Finds fault with Google's Secret SauceAs complex as Google's PageRank may be, search experts at Yahoo seem to think it's not complex enough. Based on patent filings, Yahoo is dabbling in ranking algorithms that incorporate more user behavior data in advance of the company's next run at toppling Google's haloed relevance.

Seeing will be believing when it happens, of course, as Google is highly secretive about how its search engine calculates PageRank. If history is any indication, they're already way ahead on behavioral factoring.
Nonetheless, Yahoo can afford the best search engineers in the business (if they can get them before Google does, anyway) and the patent filings shed some light on how PageRank is currently calculated and ways it might be improved in the future.
Bill Slawski, Director of Search Marketing at KeyRelevance, goes into painstaking detail of Yahoo's user data challenges at his SEObytheSea blog. Patent language, especially when dealing with algorithms, can be confusing and dense, so we'll just highlight a few interesting points and leave the lexicographical deciphering to you.
Some Yahoo assumptions about PageRank and flaws associated:
- Internal and external links are often weighed equally even though internal links can be less reliable and more self-promotional. Some links, like disclaimer links, are rarely followed.
- PageRank ignores that webpages are often purchased and repurposed, decay or become less valuable over time at variable rates.
- Current calculations, like TrustRank, are engineered more to combat webspam than to reflect actual user behavior.
- Sometimes PageRank deals with links in bulk, aggregating according host or domain, also known as blocked PageRank.
What Yahoo plans to do about it:
- Measure link weight – influenced by the frequency with which users follow a link
- Note when links are ignored and users leave (teleport) to another page of their choosing
- Calculate the probability that a user stops and reads a webpage rather than views it and moves on.
- Incorporate user data into the algorithm – "User Sensitive PageRank could reflect "the navigational behavior of the user population with regard to documents, pages, sites, and domains visited, and links selected."
- Personalize PageRank based on demographic information – age, gender, income, user location)
- Emphasize recent information
- Weigh anchor text more heavily – the patent filing calls anchor text "one of the most useful features used in ranking retrieved Web search results"

Talk or Action
The issue I have with this is, if Yahoo is able to develop this system, and it is more accurate than Google, why do their SERP's not reflect it?
Relying More On User Data
Yahoo has always paid more attention to human behavior in regards to a website - looks like this time there is an increasing relience on this factor, which I personally think is good as long as high competitive keywords are involved!
yes i would agree to need to
yes i would agree to need to find a middle ground consering this
thanks

Yahoo really needs to stop
Yahoo really needs to stop Google's Monopoly right now -_- before its to late
thanks
thanks ; )
thanks
thanks for that valuable advice here...i really appreciate it
cool design web web
Nice comments
Its really a great article.
Why Google
I know google have also commercial service but in term of support google provide equal effort for commercial and non-commercial user. Google bot is very very very which is never possible to reach.
thanks
thanks for that post there ;)
thanks
thanks for that post ...
Ineresting Appoach
Ineresting appoach Yahoo is taking with the user influence. Eventually we all know it's going to lead to that. I'm actually suprized it has not yet been done with Google. I would expec them to be doing something similar to this soon with their search. Or well, may be they are and just have not let us in on it.
If this is the case
Well, if this is the case, my question would be then why on a user-level are Yahoo.com SERP's traditionally not as targeted and as relevant as Google.com? Breaknig the down the methodology behind someone else's machine only makes sense when you can use that information to develop a superior machine, or at least work towards it - two things I do not see Yahoo doing.
Yahoo handling pagerank and algorithm
Unfortunately google did come up with a very stron algorithm when it comes to page and website relevance, and it will be difficult for Yahoo to ever compete with it imho. Google is simply way to far ahead of the game. As well, Google has streamlined its search which is functioning (sic) properly, while Yahoo seems to continue to have issues with quality of search results.
Lower costs
Maybe they can lower there costs to help everyone out.
Google
Cant see anyone toppling Google for quite some time
hmmmm
I think this could be a good starting point for yahoo to pull itself out of the hell it has slipped into. Although "page rank" means very little if the incoming links are not engineered properly.
I prefer google better, it
I prefer google better, it gives me better top ten exposure for all of my search keywords, yahoo give me different results.

Yahoo vs Goo gle
Goo gle is better than Yahoo right now...
But when Yahoo merge with Microsoft...
Goo gle will become extinct!
Page Rank Info
Well the page rank algorithm is changing constantly. So, it doesn't matter if YAHOO says that it isn't that good. Because nobody cares what yahoo thinks because their search engine SUCKS!! lol.
google tops
while yahoo has some good features site explorer for one, if your running an online business you have to focuses your attention on big G , the multitude of apps available from your google account far out weigh anything yahoo offers,and as the big player in the search game if your not focusing there your not doing yourself any favours
Google vs Yahoo
...I'd take Google any day.
We love Yahoo
Yahoo has been around a lot longer then Johnny come lately Google. Google does well in searches but now Yahoo just made an adjustment and is above Google. Yahoo has far better News, e-mail, social aspects, video IM messenger, yellow page look up, travel and hundreds of other things that Google does not have. Google will not know how to handle their first problem when it comes up. Yahoo has been through it and will once again rise up and beat google and leave sorry google in the dust.
search engine
What make a compitition better, make a search and result better.
what about msn. visit optimization page in 123ecommerce.net, the secret is not easy to catch.
Yahoo Google comparison
I think Yahoo is a far better search engine. It always delivers consistent relevant results. The question here really should be...Can Google ever catch up with Yahoo and become a major portal? Yahoo is the number 1 site on the internet, and it has been for a long long time! I don't think Yahoo has anything to worry about.
Yahoo already caught Google long ago
Yahoo delivers higher quality search results already. Google's results are great if you are looking for the site that bought their way on to Google. If you are not willing to play their game then good luck. Hat's off to Google for "monetizing" the web. But I have a nice little business and I only rank on Yahoo. I stopped trying to rank on Google a long time ago. #1 on Yahoo and #9 on Google. The 8 sites above are usually never relevant and most of them are indian scraper sites of my site with a bazillion links from other scraper sites. Goooooogle s s s s sucks.
Competition is a Good Thing
Regarless of what one thinks of Google or Yahoo, competition is the only way to keep the game going forward. Google is often critized for being a bully when it comes to page rank. One can argue the case either way and still not have a commonly agreed point of view.
It can be tough for those of us who have to contend with getting or keeping page rank, regarless of who you favor. One thing is pretty much certain, what ever happens between Google and Yahoo will keep the SEO community busy for some time to come.
It also important to note that the search engine game is an open field where anyone can play. If someone comes along with a better mouse trap the world will quickly beat a path to their door.
Why Google Anyway?
I realy hate to Google, always have. Most site owners thing that by ranking high in Google they have a great site. Just getting ranked anywhere is a task nowadays. But more importantly is getting people over to your site, be it through Google, Yahoo!, Ask or even MSN pathetic attempt at a search engine.
The programming behind a search engine is not magic. What search engines should really do is delete all the old and irrelevant sites from years back. There's so much junk returned, most are just link sites of no importance.
I say hats off to Yahoo! Don't let Google bother you.
Their site is much more than a search engine, the way it should be.
ps - please read here for more info about Google's bad business practices:

Another point of view
If you are not lazy Yahoo is interesting because you get much more results, especially from people who don't care so much about how they'r ranked, more social.. On the other hand when you have a well ranked Site Google will be more satisfying as your site will be in the first 10 instead of the first 100 in Yahoo !
I am not an engineer neither a businessman, (plus I write broken english).. But I can tell you : You take all that ranking stuff to serious! That is because you are all trying to sell the same stuff..
The competition can be won once and for all if you do your very own thing. Sit back, relax and find your own way, it is right in front of you, the easy one
Take me as an example: I am a painter and I paint on the cobblestones of Paris..This way I have no competitor at all, I am just the best contemporary art cobblestones of Paris rock painter ever in the entire universe !jaspert.free.fr

Selling Out
First Yahoo and then Google became the peoples champions against the might of Microsoft, offering equality in the search results. Each in turn has attended to the making of a profit, which is fair and to be expected but in doing do has forgotten the spirit of the search. Results were once mixed with junk that made good reading and encouraged scrutiny to gain the best results. Complaints meant they focused on giving people the quick answer through businesses that would pay for sponsorship or improved listing positioning, and in doing so removed the cognitive design of the human mind. Lazy surfers love the easy approach yet fail to realise that their actions have played firmly into the hands of big business at the expence of the smaller or more localised traders. I am not saying that sponsored listings should be stopped, far from it, but something certainly does need to be done to put the fun of the search back into the system, afterall it is the surfers that matter most - not the companies tempting with large cheques.
Yahoo vs. Google????
Yahoo is so far behind as it is. You can even PUT THE NAME of a .COM website in there...and IT STILL WON'T SHOW UP ANYWHERE. As I read on this blog...Yahoo is useless...both for businesses and users who are searching for them.
Yahoo
A good thing about constant changes to the algorithms is that those who stay on top of the trends are rewarded.
Live is better
Yahoo crawl sites with 5-10 boots and google with only 1 :) maybe this is the "secret" ;) Yahoo is not good. Not for me !
and for video or images content, live.com is the king.
Yahoo vs. Google
Google's algorhythm isn't the biggest reason they are competing so well against Yahoo. Google has a HUGE advantage in that they don't charge you for inclusion in their directory. Yahoo didn't used to when they started out, but then they got greedy. And that's when Google took over.
Yahoo is CLUELESS
I believe Yahoo is clueless. They have changed the system so many times they forgot what is most important - relevant search results !!!!
Most of the keywords deliver nothing but junk. The index quality is pale in comprising to Google. Yahoo will never catch
http://www.goarticles.com/cgi-bin/showa.cgi?C=720144
On 12/13/07 we had no choice but to stop all our ad campaigns and our client's campaigns on Yahoo Ads. As well as notify our colleagues and ask them to start an investigation on this issue. We believe Yahoo company is involved in committing fraud against its own advertisers. We have documented several occasions where we have bid and started to pay for a keyword. Immediately the page rank that was #10 under the same term has disappeared or dropped down dramatically to position #30. This appears to be be done purposely in order to drain the yahoo ads account funds faster. Ultimately creating major revenue for the company. Basically if you have a good rank on the term and you decide to buy the term to appear in sponsored links also, you are guaranteed to loose your great rank and other ranks. Our site had ranked always 5-12 under term auditions since the year 2000. Since we signed up with yahoo ads and bid on some terms we lost ranks. The damage that was caused from by this drop has been estimated in well over 100,000 dollars because we have lost traffic. In fact we only spent about $500 on ads monthly and lost $10000 monthly because of that. So is it really worth it ? On another note Yahoo is involved in commiting fraud against its own advertisers.
Paid Inclusion Skews Results
In my opinion, the quality of Yahoo!'s search algorithm is irrelevant as long as they continue to skew their results so heavily toward their paid inclusion program.
Where is the competition of Google?...
The domination of Google in the Search Engine field would deserve a heavy weight response from the competition and - why not? - a more accurate evaluation of every internal and external link.
Can Yahoo Catch Google? - I Dont Think So!
It would be really great if yahoo could take a serious slice of the search engine market and actually manage to produce some relevant results. The problem is that although Yahoo doesnt like to think it has a problem with SPAM sites it does. You only need to look at any search term and the vast majority of the results after the first page are sub domains starting with the keyword. Whatever floors that Google may have (and there are quite a few) they still produce fairly acurate relevant results (although they do have a tendency of throwing out good sites as well as bad ones in their attempt to beat spam).
Attending to their own policies...
In my experience as a paid advertiser on almost all of the existing search engines, I realize the massive benefits I receive when the search engines actually follow their own policies. For instance, Google and Yahoo both have a "double serving policy" or a policy that keeps one company from creating multiple identities through different looking websites and advertising on the same keywords. In the data industry, there is a large group of websites created by the same company who blanket the paid results, which ends up devaluing the search results for visitors because they are selling the same product in the end. Google has been proactive in finding links between these websites, knocking them off one by one when they find another link, but Yahoo (who has the exact same policy) has very reluctantly listened to my complaints and has continually avoided doing anything about the situation. Once Yahoo takes their paid advertisers seriously and starts to follow their own policies, then and only then will they be moving closer to being a class-act search engine like Google.
Yahoo
I like Yahoo better, it gives me better top ten exposure for all of my search keywords, google is taking forever.
Would that mean the rich get richer?
surely if they will be adding a measure of user frequency that would mean the rich will get richer all the time and the poor poorer – imagine trying to get a new site included, you would never be able to compete against older sites regardless of content or links.
They won't catch up.
Even if yahoo's search is more accurate they won't catch up. People are used to googling things. It has become "the search engine." Too many programs have google search bars interwoven in their pages.
Yahoo! is Doing What Goolge Has Already Done
In some instances I like Yahoo! seach results over Google search results, but for some reason I still use Google search heavily and put more focus on ranking in Google. This is because Google has leveraged itself as a search company or THE search company, while Yahoo! is more of a portal -- news, email, chat, groups, social, etc. with search just being another portal widget.
Anyway, with that said, I believe Yahoo! is light years behind Google when it comes to search technology, and if they are attempting to counter act on Google PageRank technology then they already taking the wrong approach, because they plan to create a PageRank algorithm which is the complete opposit of Google technology. This is wrong for many reasons, but the main reason is because Google is a powerful company who employs top engineers, this mean everything Yahoo! is about to try has either already been done or been tested and most likely proven to be a failure, since Google themselves is not coding their algo in this type of way.
Instead Yahoo! should trail and follow exactly how Google PageRank work and improve upon that, otherwise they will be just trying what already has been done and will continue to be lightyears behind Google if they keep trying to go against the grain. Plus, Yahoo! like to share their data to the public so they need to take into consideration the fact if they provide PageRank in a certain manner it may make it easily exploited for SEO. I applaud Yahoo! efforts, but I think they should rethink their strategy and go about this the right way.
Simply put...
Google vs Yahoo
