Google And Yahoo Search Engine Computer Science Essay

Web hunt engines are keys to the huge hoarded wealth of information. Dependence on the hunt engines is increasing drastically for both personal and professional usage. It has become indispensable for the users to understand the differences between the hunt engines in order to achieve a higher satisfaction. There is a great mixture of hunt engines which offer assorted options to the web user. Therefore, it is important to measure and compare hunt engines in the pursuit of a individual hunt engine that would fulfill all the demands of the user.

The chief job is confronting by people, which search engine is really utile for happening dependable, relevant and fresh consequences. There are plentifulness of hunt engine are available for seeking but, this thesis will cover which engineering are running behind Google and Yahoo! ! hunt engine.

Google and Yahoo! have their ain algorithm for indexing the web site.

Introduction of Search Engine:

In simple words a Search engine is package that searches through a database of web pages or web resources for a piece of information, keywords, constructs etcaˆ¦

There are many types of Different Search Engine available in Market.

for illustration msn, Google, Yahoo! , inquire etcaˆ¦

Primarily package plan called automatons or spiders that crawl through all the files on the Internet and download them into a searchable database.These works every bit indexes to the literature available on the web. In the context of the Internet, Search engines normally refer to the World Wide Web and non other protocols or countries.

Search engine is helpful for placing beginnings, set uping luminary, look intoing facts, and discoursing what names to utilize for different things.

There are a figure of hunt engines available on the web. Most of the Search engines provide website reappraisals and home page services in add-on to keyword hunts.

But, in this present survey two most popular hunt engines have been studied in footings of its available web resources with mention to Physics-India in Google and Yahoo! .

Introduction of Google

Google is one type of web hunt engine. When user wants to happen something around the universe utilizing cyberspace at that clip Google comes into the image. Google Search is the most-used hunt engine on the World Wide Web. So Google provide the full information base on keyword which is put by the user in to seek box of Google hunt engine. When user entry any keyword for hunt Google show all the related consequence of the keyword.

Introduction of Yokel!

Yokel! is one of the best known and most popular Internet portals. Originally a capable directory of sites, it now is a hunt engine, directory, and portal. To travel to the Yokel! ! portal and chief starting point, useA www.Yahoo! .com.

For direct entree to the hunt engine, and for the directory useA This reappraisal chiefly coves the hunt engine characteristics. Use theA tabular array of contentsA on the left to voyage this reappraisal.

Literature reappraisal and proposed overview:

Search engine engineering has had to scale dramatically to maintain up with the growing of the web. In 1994, one of the first web hunt engines, the World Wide Web Worm ( WWWW ) [ McBryan 94 ] had an index of 110,000 web pages and web accessible paperss. As of November, 1997, the top hunt engines claim to index from 2 million ( WebCrawler ) to 100 million web paperss ( from Search Engine Watch ) . It is foreseeable that by the twelvemonth 2000, a comprehensive index of the Web will incorporate over a billion paperss. At the same clip, the figure of questions search engines grip has grown improbably excessively. [ 1 ]

In March and April 1994, the World Wide Web Worm received an norm of about 1500 questions per twenty-four hours. In November 1997, AltaVista claimed it handled approximately 20 million questions per twenty-four hours. With the increasing figure of users on the web, and automated systems which query hunt engines, it is likely that top hunt engines will manage 100s of 1000000s of questions per twenty-four hours by the twelvemonth 2000. The end of our system is to turn to many of the jobs, both in quality and scalability, introduced by scaling hunt engine engineering to such extraordinary Numberss. [ 2 ]

With the explosive growing of World-Wide-Web ( WWW ) , printing papers on Internet has become more popular.But how to turn up what we need in the ocean of information is an progressively of import and pressing job. To simplify the job of acquiring relevant consequences based on the hunt question, the Internet hunt

engines were created that allowed seeking a batch of information from the World-Wide-Web in the signifier of Web pages [ 3 ] .

Search engines are among the most successful application on the Web today. They act as a system for seeking the information available on the Web by automatically seeking the contents of other systems and making a database of the consequences [ 4 ] .

The most celebrated hunt engines include AltaVista, Infoseek, Google, and MSN. They provide good seeking ability by indexing more pages on the Web and keeping the updated indices in their databases. Despite so many hunt engines are available to assist user in happening the information of their involvement, seeking on the Web is non an easy undertaking. The job is due to the huge sum of informations on

the Web and its rapid updating and growing [ 5 ] .

History of Search Engine

The first Web hunt engine was “ Wandex ” , developed by the World Wide Web Wanderer in 1993. Another really early hunt engine, Aliweb, besides appeared in 1993 and still runs today. One of the first engines to subsequently go a major commercial enterprise was Lycos, which started at Carnegie Mellon University as a research undertaking in 1994.

Soon after, many search engines appeared and vied for popularity. These included

WebCrawler, Hotbot, Excite, Info seek, Inktomi, and AltaVista. In some ways they competed with popular directories such as Yokel! ! . Subsequently, the directories integrated or added on hunt engine engineering for greater functionality.

In 2002, Yahoo! ! Acquired Inktomi and in 2003, Yahoo! ! Acquired Overture, which owned AlltheWeb and AltaVista. In 2004, Yahoo! ! Launched its ain hunt engine based on the combined engineerings of its acquisitions and supplying a service that gave pre-eminence to the Web hunt engine over the directory.

Before the coming of the Web, there were hunt engines for other protocols or utilizations, such as the Archie hunt engine for anon. FTP sites and the Veronica hunt engine for the Gopher protocol.

Recent add-ons to the list of hunt engines include, AlltheWeb, Ask Jeeves, Clusty, Gigablast, Ez2Find, Teoma, WiseNut, GoHook, Walhello, Kartoo, Snap and Mamma.

Figure: 2 hunt engine market

As per above figure: 2 Google and Yahoo! screen most of the market of the universe. Both have more popularity so other hunt engine. Google beat the Yokel! at some degree

History of Google Search Engine:

Google was co-founded by Larry Page and Sergey Brin while they were making their Ph. D. at Stanford University in 1998 and was officially launched in the autumn of 1999. This is a straightforward engine that does non back up advanced hunt sentence structure doing it really easily to utilize and retrieves pages ranked on the footing of figure of sites associating to them and how frequently they are visited, bespeaking their popularity ( ibid ) . It claims that 97 % of the users find what they are looking for.

Degree centigrades: UsersJIMIT DOSHIDesktopew dwnldgoogle snapshot.png

Figure:3 Google place page overview

Its success was based in portion on the construct of nexus popularity and PageRank. How many other web sites and web pages link to a given page is taken into consideration with PageRank, on the premiss that good or desirable pages are linked to more than others. The PageRank of associating pages and the figure of links on these pages contribute to the PageRank of the linked page. This makes it possible for Google to order its consequences by how many web sites link to each found page. Google ‘s minimalist user interface was really popular with users, and has since spawned a figure of impersonators.

Google has been estimated to run over one million waiters in information centres around the universe, and procedure over one billion hunt petitions and about 24 PBs of user-generated informations every twenty-four hours

Alternatively of ranking pages, this engineering uses an algorithm that follows links on a web page to happen other pages that link back to the first one and so on from page to page.


Google includes the following most of import characteristics:

Cached page archives.

Consequence clustered by indentation.

Result displayed option, from 10-100.

“ Google Search ” Supports:

Implied Boolean ( + ) mark, ( – ) mark.

Double quotation marks ( “ ” ) for phrases.

Stop words.

Other Search Options Available with Google:

“ I ‘ thousand Feeling Lucky ” ( goes straight to exceed graded site in question )

“ Google lookout ” ( convey up list of related sites )

“ Uncle Sam ” ( Searches govt. and Milsites )

“ Search within consequences ” option

Field seeking with ‘link ‘ merely.

History of Yokel! Search Engine:

Yokel! was co-founded by Stanford University Graduate pupils Jerry Yang and David Filo in January of 1994.Yahoo! is a capable Directory and besides a commercial portal compiled by homo. It is oldest every bit good as largest directory on the web.

Degree centigrades: UsersJIMIT DOSHIDesktopew dwnldsnapshot of yahoo.gif

Figure: 4 Yokel! hunt engine

Yokel! allows the user to set a hunt question, its strength lies in the classs and each that can take a user step-by-step to the desired capable class.


Yokel! is hierarchically organized with capable catalogue or directory of the web which is browseable and searchable.

Linkss to assorted services are accomplished in two ways such as by user ‘s entries and through automatons that retrieve new links from known pages.

Yokel! indexes web pages, UseNet and e-mail reference.


Topic and part specific “ Yokel! ”

Automatic shortness.

No instance sensitiveness.

The sentence structure that Yahoo! follows for seeking is reasonably standard among all hunt engines.

Search Option:

Users can shop Yahoo! ! Simply by snaping on the assorted classs listed on each page, or can seek Yahoo! ! By come ining a word into the hunt box that appears on every page in the directory. Again one can unite the two schemes and can “ shop and so hunt ” or “ hunt and so browse. ”

Other Search Options:

Yokel! ! News

User may unite any of the question sentence structure every bit long as the sentence structure is combined in the proper order, which is + , – , T: “ ” , and * .

If Yahoo! does non happen any duplicate entries, refering to a question, in its chief database, the question will automatically be transferred to the Inktomi database, a hunt engine that automatically ‘crawls ‘ the text of the full web. Inktomi database contains consequences for literally 1000000s of single web pages.

Yokel! therefore looks for information in:

Yokel! ! Categories.

Web sites listed in Yokel! .

Web pages indexed by Inktomi.

Working of Google Search Engine:


Figure: 5 how work Google hunt engine

Google Search ( or Google Web Search ) is a web hunt engine owned by Google Inc. Google Search is the most-used hunt engine on the World Wide Web, having several hundred million questions each twenty-four hours through its assorted services.

The order of hunt consequences on Google ‘s search-results pages is based, in portion, on a precedence rank called a “ PageRank ” . Google Search provides many options for customized hunt, utilizing Boolean operators such as: exclusion ( “ -xx ” ) , options ( “ twenty OR yy ” ) , and wildcards ( “ x * x ” ) .

The chief intent of Google Search is to run for text in Web pages, as opposed to other informations, such as with Google Image Search. Google Search provides at least 22 particular characteristics beyond the original word-search capableness. These include equivalent word, conditions prognosiss, clip zones, stock quotation marks, maps, temblor informations, film beginnings, airdromes, place listings, and athleticss tonss. There are particular characteristics for day of the months, including scope, monetary values, temperatures, money/unit transitions, computation, bundle trailing, patents, country codifications and linguistic communication interlingual rendition of displayed pages.

Datas about the frequence of usage of hunt footings on Google ( available through Google Adwords, Google Trends, and Google Insights for Search ) have been shown to correlate with flu eruptions and unemployment degrees and supply the information faster than traditional coverage methods and authorities studies.


Google ‘s rise to success was in big portion due to a patented algorithm called PageRank that helps rank web pages that match a given hunt twine. When Google was a Stanford research undertaking, it was nicknamed BackRub because the engineering cheques backlinks to find a site ‘s importance. Previous keyword-based methods of ranking hunt consequences, used by many hunt engines that were one time more popular than Google, would rank pages by how frequently the hunt footings occurred in the page, or how strongly associated the hunt footings were within each ensuing page.

The PageRank algorithm alternatively analyzes human-generated links presuming that web pages linked from many of import pages are themselves likely to be of import.

The algorithm computes a recursive mark for pages, based on the leaden amount of the PageRanks of the pages associating to them. PageRank is thought to correlate good with human constructs of importance. In add-on to PageRank,

Search Consequences:

The exact per centum of the sum of web pages that Google indexes is non known, as it is really hard to accurately cipher. Google presents a two-line sum-up and besides a prevue of each hunt consequence, which includes a nexus to a cached ( stored ) , normally older version of the page.

Google ‘s cache nexus in its hunt consequences provides a manner of recovering information from web sites that have late gone down and a manner of recovering informations more rapidly than by snaping the direct nexus. This characteristic is still available, but many users are non cognizant of this because it has been moved to the prevues of the hunt consequences presented following to these.

Non-index able informations:

Despite its huge index, there is besides a considerable sum of informations available in online databases which are accessible by agencies of questions but non by links. This alleged unseeable or deep Web is minimally covered by Google and other hunt engines.

The deep Web contains library catalogs, official legislative paperss of authoritiess, phone books, and other content which is dynamically prepared to react to a question.

Google Optimization:

Since Google is the most popular hunt engine, many webmasters have become eager to act upon their web site ‘s Google rankings. An industry of advisers has arisen to assist web sites increase their rankings on Google and on other hunt engines.

This field, called hunt engine optimisation, efforts to spot forms in hunt engine listings, and so develop a methodological analysis for bettering rankings to pull more seekers to their client ‘s sites. Search engine optimisation encompasses both “ on page ” factors and Off Page Optimization factors ( like ground tackle text and PageRank ) .

The general thought is to impact Google ‘s relevancy algorithm by integrating the keywords being targeted in assorted topographic points “ on page ” , in peculiar the rubric component and the organic structure transcript ( note: the higher up in the page, presumptively the better its keyword prominence and therefore the ranking ) . Too many happenings of the keyword, nevertheless, cause the page to look fishy to Google ‘s Spam checking algorithms. Google has published guidelines for website proprietors who would wish to raise their rankings when utilizing legitimate optimisation advisers.


Google hunt consists of a series of localised web sites. The largest of those, the site, is the top most-visited web site in the universe. Some of its characteristics include a definition nexus for most hunts including dictionary words, the figure of consequences you got on your hunt, links to other hunts ( e.g. for words that Google believes to be misspelled, it provides a nexus to the hunt consequences utilizing its proposed spelling ) , and many more.

Search Syntax:

Google ‘s hunt engine usually accepts questions as a simple text, and breaks up the user ‘s text into a sequence of hunt footings, which will normally be words that are to happen in the consequences, but one can besides utilize Boolean operators, such as: citations Markss ( “ ) for a phrase, a prefix such as “ + ” , “ – ” for qualified term or one of several advanced operators, such as “ site: ” . The WebPages of “ Google Search Basics ” describe each of these extra questions and options.

Query enlargement:

Google applies query enlargement to the submitted hunt question, transforming it into the question that will really be used to recover consequences. As with page ranking, the exact inside informations of the algorithm Google utilizations are intentionally vague, but surely the undermentioned transmutations are among those that occur:

Term reordering: in information retrieval this is a standard technique to cut down the work involved in recovering consequences. Steming is used to increase hunt quality by maintaining little syntactic discrepancies of hunt footings.

There is a limited installation to repair possible misspellings in questions.

Working of Yahoo! Search Engine:

Yokel! ! Search is a web hunt engine, owned by Yokel! ! Inc. and was as of 2009, the 2nd largest hunt directory on the web.

Yokel! ! Search, originally referred to as Yokel! ! provided Search interface, would direct questions to a searchable index of pages supplemented with its directory of sites.

Yokel! does non utilize Web Crawling for recovering the consequences. It uses Inktomi for acquiring consequences of keywords which are non found by the Yokel!

In 2009, Microsoft and Yahoo! announced a trade in which Bing would power Yahoo! ! Search.

Search Technology Acquisition:

Seeking to supply its ain hunt engine consequences, Yahoo! ! acquired their ain hunt engineering.

In 2002, they bought Inktomi, a “ behind the scenes ” or seek engine supplier, whose consequences are shown on other companies ‘ web sites and powered Yokel! ! in its earlier yearss. They purchased Overture Services Inc. , which owned the AlltheWeb and AltaVista hunt engines. Initially, even though Yokel! ! owned multiple hunt engines, they did n’t utilize them on the chief Yokel! .com web site, but kept utilizing Google ‘s hunt engine for its consequences.

In 2003, Yahoo! ! Search became its ain web crawler-based hunt engine, with a reinvented sycophant called Yokel! ! Slurp. Yokel! ! Search combined the capablenesss of all the hunt engine companies they had acquired, with its bing research, and set them into a individual hunt engine. The new hunt engine consequences were included in all of Yahoo! ! ‘s sites that had a web hunt map. Yahoo! ! besides started to sell the hunt engine consequences to other companies, to demo on their ain web sites.

In 2007, Yahoo! ! Search was updated with a more modern visual aspect in line with the redesigned Yokel! ! place page. In add-on, Search Assisst was added ; which provides real-time question suggestions and related constructs as they are typed.

In 2008, Yahoo! ! Search announced the debut of a new service called “ Construct Your Own Search Service, ” or BOSS. This service opens the doors for developers to utilize Yahoo! ! ‘s system for indexing information and images and make their ain usage hunt engine.

Table: 1 Google & A ; Yahoo! Comparison

( A. ) Similarities of Google and Yahoo! Search Engine

Several similarities of Google and Yahoo! Search engines are found after sing both web sites and proving with a question.

First of wholly, both search engines give great advantages for users ; they provide optional tips or techniques to assist users seek expeditiously. Some similar tips are found.

The first technique is utilizing specific and alone words to depict what we are looking for. If the keywords are more general or equivocal words, the big figure of irrelevant feedback paperss will be retrieved.

Another technique is utilizing citation Markss around keywords so that the seekers can happen the exact words and contract the figure of hunt consequences.

There are several techniques to contract the hunt consequences, including

( 1 ) restricting sites/domain, .edu,,

( 2 ) stipulating types of files to.htm/.html, .pdf, .doc, and.txt,

( 3 ) utilizing operator ( – ) before the word that we do non necessitate it appears in the hunt consequences,

( 4 ) utilizing operator ( + ) before the word that we do necessitate it in the hunt consequences, and ( 5 ) utilizing Boolean operators like AND, OR, and NOT to stipulate seeking footings.

The other techniques are utilizing extra options to acquire more relevant hunt consequences. For case, users can stipulate updated files, states, linguistic communications, and figure of consequences per page.

These techniques from both hunt engines are really helpful for users to recover more precise consequences. For illustration, giving the question like “ swine grippe ” + unt, both search engines returned many web pages about swine grippe with the word “ unt ” , which is the University of North Texas. This can cut down non merely the clip procedure the hunt engines, but besides the clip to ticket the best precise hunt consequences.

The 2nd similarity of these hunt engines is that they provide many classs for the hunt consequences, such as web, images, pictures, shopping, intelligence, and athleticss. With choosing a specific class like images, a user can recover merely images on the webs. Users can besides specify specific type of file like.pdf, .doc, and.jpg, which helps users to acquire more precise and cut down clip procedure.

Third, when typing the keywords, Yokel! suggests the full key words every bit good as Google. This helps users to choose the full question every bit fast as possible. Proposing the full keyword is a smart undertaking for both hunt engines because it is an Artificial Intelligent portion, which tries to think users what the following word of the question is. For illustration, when typing “ swine ” , both search engines suggested the word “ grippe ” as the following word.

Next, the hunt consequences of both engines are rather similar forms, which show the rubric in the first line, the brief description of web page in the following several lines, and the URL or web page ‘s reference. This snipping for each web consequence is adequate information that a user can rapidly scan and travel to happen information from other web pages in the graded consequences.

Last but non least, after submitted a question, both search engines instantly returned the relevant consequences, along with the big entire figure of web sites retrieved. This shows the ability and efficiency of both search engines.

Obviously, with these beforehand tips for both hunt engines provided on their web interface, they become the most top-two popular usage over the others in the universe. These are the great hunt engines that people use to happen tremendous information on the Internet since they provide the ways to recover more relevant hunt consequences.

( B. ) Contrast between Google and Yahoo! Search Engine

Interface, Design, and Layout:

The most obvious difference between these two Web sites is about the Interface, Layout, and Design of the pages.

Google offers a really Clean and simplistic interface, whereas Yokel! ! ‘s is busy and cluttered.

Simple design should ever be used to avoid complexness and confusion to the user. When a user is non required inordinate text and images, they will experience more at easiness and comfy while utilizing your Web site.

Ultimately, a simplified interface means that the Web site will be accessible to all types of people with different accomplishment degrees, therefore increasing the potency for a important user return.

Another cardinal facet of Design and serviceability is specifying or understanding the intent of the Website. Due to the simplistic nature of the Google Web site, it is rapidly evident to the user that the intent of the site is for seeking.

The user is instantly drawn to the centre of the screen where information about the Web site is readily available. In blunt contrast, Yahoo! ! ‘s place page is a disorderly muss. It can be ill-defined to the user what the chief intent of the Yokel! ! Main site is.


Ad is a necessary characteristic of many Web sites. However, most users see advertizements as a nuisance. As such, it is of import to avoid advertizements every bit much as possible.

This is particularly true of any big ocular advertizements and particularly pop-up advertizements. Both Google and Yahoo! ! utilize text-based and low-intrusion advertizements when a hunt is initiated.

However, Yahoo! ! makes usage of several other types of ocular advertizements through its Web site, which finally do non reflect the demands of the user. Ad should non be an issue for the pupil ‘s professional ePortfolio.


Consistency is a important component of Web site design. Although both Yahoo! ! and Google offer many of the same characteristics ( electronic mail, intelligence, and hunt ) , the internal pages of each respective.

Web site are drastically different. Google continues with its subject of clean interface throughout every one of its Web pages.

This has the consequence of uniformity and consistence. Yahoo! ! , on the other manus, has drastically different pages in its Web site.

For illustration, Yahoo! ! Autos looks wholly different than Yokel! ! Music or Yahoo! ! News. Each channel maintains a nexus to the chief Web site, but finally, there is small consistence within the Yokel! ! Web site.

Navigation and Usability

A concluding component of successful Web site design is the pilotage and serviceability of the Web site. When planing a site, it is indispensable to make pages that can be viewed by multiple users with entree to multiple engineerings.

Not everyone has the same size proctor, non everyone uses the same Internet browser, and non everyone utilizes the same font type or size. Therefore, it is imperative that one keeps the user in head in developing a functional Web site that can be accessed and used by all.

Finding your manner through a Web site should be comparatively easy to make. Use devices such as breadcrumb trails ( strings of text ) , headings or footers, and tabbed shoping to farther relieve the confusion of voyaging a Web site. Some of these devices may non be available utilizing Drupal for the pupil ‘s ePortfolio.


Visiting both Google and Yahoo! web pages and proving them with a keyword, some differences between them are found.

First, Yahoo! hunt engine home page seem to be more colourful and attractive than Google. Yokel! provides non merely the interface but besides updated intelligence, new tendency, other links like game, hot occupations, courier, films, athletics, finance, cars, travel, eBay, and conditions.

These colourful links with little images are on the sailing master bill of fare that users can rapidly ticket and snap these links. Google home page, on the other manus, does non supply unrelated links. In fact, it shows merely the hunt interface, the Google ‘s trade name ( image ) , and other classs of hunt types, such as images, pictures, map, intelligence, books, finance, bookman, and translate.

Second, Google seems to recover relevant consequences faster and more precise than Yahoo! . When proving both hunt engines with the questions “ swine grippe ” + unt, which means that we want to seek the exact “ swine grippe ” and return the consequences incorporating the word “ unt ” , Google returned the consequences faster and more relevant consequences than Yahoo! ;

Google returned many web sites about swine grippe incorporating the word “ unt ” in every web site within 0.12 seconds. Furthermore, the first top five of the consequences from Google are more relevant than those from the Yokel! . These represented that Google took greater advantages over Yokel! .

Third, although both search engines provide many extra classs to assist users, Google gives more utile classs including books, interlingual rendition, bookman, paperss, reader, sites, and groups.

These classs provide great advantages for academic people like pupils, research workers, professors, or even doctors. Therefore, users can seek whatever they want with these classs provided in Google.

Accomplishments of Google Search Engine

Google AdSense

I: searchgoogle-adsense1.jpg

And on the other manus, this service besides be a money machine for Google. Equally many as 30 % of Google ‘s entire gross in the one-fourth 4 2010 comes from AdSense.

2. YouTube

I: searchyoutube_logo_standard_againstwhite-vflKoO81_.png

Google decided to purchase YouTube in 2006 with a immense sum, USD 1.65 billion. For several old ages, it was rumored this site does non bring forth net income. But now no longer seem so, YouTube was reported to be a large beginning of gross to 3 billion ad positions per hebdomad.

3. Google Maps

I: searchmap3.png

Google Maps is non a large gross manufacturer, but are the anchor for other Google services such as Latitude, Places and Maps Navigation. Service function is important for Google to cover with competition.

Gross comparing Google and Yahoo! of twelvemonth 2011:

Its latest fiscal consequences, for the 2nd one-fourth of 2011, showed falling grosss and net incomes that were mostly down to its procrastinating show advertisement concern.

Plotted historically, this all starts to look terminal. Overall grosss have n’t been this low since the 2nd one-fourth of 2012, and overlaid with Yahoo! ‘s strategic moves off from tech to media, back to tech and so back to media once more more late – as Ross Levinsohn indicated. This graph shows the familiar diminution.

Yahoo V Google grosss Figure: 16 Google gross ( ruddy ) vs Yahoo! gross ( bluish ) – Q1 1996 to Q2 2011

Display advertisement was one time Yahoo! ‘s nucleus concern, and one it could trust on working. Repeated executive shufflings, low morale and a revenue-sharing understanding in hunt with Microsoft have all sucked the success out of the company. Yokel! is now faced with sitting back and watching its challengers benefit from the growing in advertisement show – non merely some serious attempt from Google which now outsells Yokel! in show, but besides Facebook, which has increased its show ad cost-per-click 74 % in the past 12 months. ( We ca n’t plot Facebook ‘s grosss here, because it ‘s a private company, but you can wager that it is another of the topographic points that Yahoo! ‘s lost gross has gone to.

Yokel! ‘s stock dropped at the terminal of the US twenty-four hours but rose once more after hours.

Second one-fourth of 2011:

aˆ? Revenues excepting traffic acquisition costs [ the sum Yokel! has to pay out to sites for directing it traffic ] were $ 1.076bn, down 5 % twelvemonth on twelvemonth.

aˆ? Net net incomes were $ 237m, up from $ 213m in Q2 2010.

aˆ? Display advertisement gross rose 2 % from Q2 2010, though it had seen 6 % growing in Q1.

aˆ? Search gross fell to $ 371m, down 15 % year-on-year.

From the analysts:

aˆ? “ Despite some optimism about, growing in hunt advertisement gross, Zacks acknowledges that Carol Bartz ‘ turnaround program is traveling really easy. “ There are a twosome of factors that will probably work against it. The first is the turning importance of Google ‘s show web, which has steadily expanded the market in the small-medium concern section and enabled it to displace Yahoo! ! as the biggest participant in the overall show ad market. We think there is limited satisfaction in the fact that Yokel! remains good positioned at the large participants. The composing appears to be on the wall. ”

aˆ? Clayton Moran of Benchmark in Florida: “ It ‘s about difficult to believe they can go on to let down the Street, which we thought had reasonably weak outlooks, but they ‘ve done that. ”

aˆ? Ben Schachter of Macquire Research: “ They are seeking to repair batch jobs that do necessitate to be fixed, but unluckily as they are repairing those jobs, new 1s are starting up. ”

What ‘s the solution?

Carol Bartz ( who has been in the top occupation since January 2009 ) is running out of clip to turn out that Yokel! is n’t in terminal diminution. Every go throughing one-fourth – and amid progressively negative studies – her staff cuts, executive alterations, selloffs ( goodbye Delicious, now owned by the cats who created YouTube ) and ambitious statements on the house ‘s strategic way do n’t look to be doing any difference at all. That search/advertising trade with Microsoft is besides neglecting to assist ; Yahoo! incriminations that outright for drawing down its gross figures because of the portion it has to give Microsoft.

You can wager that behind the scenes, programs are reasonably advanced for cut offing Yahoo! ‘s most profitable parts – viz. its 43 % interest in Chinese e-commerce group Alibaba, the high-profile exposure sharing site Flickr and its advertisement gross revenues substructure. The inquiry is, one time those are gone, what ‘s left, and to whom does it hold any value? Yahoo! now merely seems good for pulling orbs, but they ‘re low-value 1s. It ‘s become the Woolworths of the cyberspace.

Now vibrating at $ 14.59 per portion, those dizzy yearss of February 2008 when Jerry Yang proudly headed off that $ 31 per portion, or $ 44.6bn offer, to purchase Yahoo! . That now seems something of a Pyrrhic triumph.

Difference between Google and Yahoo! SEO:

How are you all making today? It ‘s been a busy hebdomad me. I have been utilizing assorted analytic tools to analyze and analyse my website traffic beginnings and few of them are: Stat counter, Google Analytics, Complete, Alexa and most significantly my web hosts ain Awstats applications.

Recently I have been making a batch of keyword research utilizing Market Samurai and it has helped me top musca volitanss on the Google hunt engine consequences on the keywords of my most popular web log stations. In add-on, to analyze my visitant human ecology and the traffic form I was making a spot of research. One peculiar fact that struck me while making all the research is that 96 % of my website traffic is from Google hunt engine and 4 per centum from other hunt engines like Yokel! and Bing.

Google Domination

In the hunt engine sphere, Google merely dominates that traffic that I receive organize the web site. This does non intend that people do non utilize Yokel! , Bing or other Search engines. It merely means that I am merely optimized for Google and do non rank anyplace on Yokel! . Even though about 80 % of the Internet users use Google hunt, There is a bracket of 20 % of users utilizing Yokel! hunt – This means you have a immense potency to convey some untapped beginning of traffic to your web sites.

Factors impacting the Difference between Google and Yahoo! SEO On Page SEO factors are given more importance by Yokel!

Keyword denseness is critical for Yokel!

Internal links count for page rank in Yahoo! System. Yokel! does non look into Java and iFrame use every bit much as Google bots does.

The above are few major differences between the Google and Yahoo! Algorithm or the factors that they consider before ranking a page in hunt engines. The factors in item are explained below:

On-Page SEO factors:

On page SEO factors impacting your ranking is something that you have entire control on. If you are utilizing a Word Press web log, so I take entire control of the On page SEO utilizing 2 stop uping – wpSEO and SEOPressor. In instance you are non utilizing a blogging platform, still you could better your onpage optimisation, look into out my elaborate article on Onpage SEO optimisation here

Keyword Density:

The factor is already portion of the OnPage SEO. KD is the ratio between entire figure of keywords as calculated against non-keywords used in the organic structure text, rubric, link-anchor text, and meta tickets. Even though Google besides gives it importance but its relatively less of import unlike in Yokel! .

Internal links count for page rank in Yahoo! system: Google considers merely external backlinks as a factor impacting the Google PageRank while Yahoo! besides has an internal PageRank system that is on the other manus influenced by internal linking besides. Hence Internal cross linking is good if you want to optimise for Yokel! hunt. The Yokel! page rank is called as “ web rank ” and is on a graduated table from 0 – 10.

Java and iFrame use:

Google has an extended hunt and indexing algorithm. Yahoo! on the other manus does non index or look into Java and iframes every bit much as Google does.


If you are looking frontward to accomplishing higher ranking in Yahoo! hunt consequences, so you must affect the Yokel! Slurp ( bot ) with first-class onpage SEO. Make sure you have the right keyword denseness, Title, Headings, Meta tickets, Internal links etc.

Bonuss: If you want to see how your page would look for a hunt engine bot through its eyes, look into out the Search Engine Spider position simulator. Hope this article on Difference between Google and Yahoo! SEO was helpful.

This logic is why Yahoo! lost to Google in the first topographic point.

At some phase Yahoo! began to set the advertizer foremost. It stopped seeing clients as people it needed to assist happen what they wanted rapidly. It fell into the trap of gluey marketing-keep them on the site every bit long as possible ; demo them as many ads as possible.

The Yokel! home page started off as a straightforward directory of the Web and for many old ages it stayed like that. However, sometime after 2000 it began to acquire more and more complicated and advertiser-focused. By 2004, there were 255 links on the Yokel! home page. It had reached a phase of monolithic, overbearing jumble and bumptiousness.

“ It had nil to make with the user, but what Yahoo! wanted the user to make, ” Yahoo! ‘s Tapan Bhat, senior frailty president of Integrated Consumer Experiences told the Wall Street Journal in July 2008.

However, Yahoo! did seek to refocus. By 2006, there were about 170 links on the home page. By 2007 it was down to about 140, by 2008 about 120 and by 2009 about 100.

This is the age of client power, client control, client laterality. Today, the client is non king ; the client is dictator. Google, so far, has put the demands of the client, non the advertizer, foremost.

Yokel! and Google have the same advertisement gross theoretical account. However, Google is n’t focused on increasing page positions and ad arrangements but instead on increasing relevancy. It is focused on doing ads utile.

In world, Google is non a hunt engine ; it ‘s a clip salvaging device.

Difference between Yahoo! Finance and Google Finance:

Yokel! Finance and Google Finance serve an progressively of import map in this twenty-four hours and age. Let ‘s see what both sites have to offer.

Yokel Finance
