Analyzing Yahoo/Inktomi's & Google Ranking Algorithms

Will The algorithms change and if how for Yahoo/Inktomi

[aaaaa]

;)
Google is now reported to be responsible for 70% of the search engine results - because of it's databases being "powered" for:
--> YAHOO - web search
--> AOL
--> NETSCAPE
--> IWON
--> EARTHLINK
etc...
If Yahoo uses Inktomi's search as it's default search - as it recently now uses Google - it may be vital to accummulate as much information on the new or changed ranking algorithms that will be used.
As much as Google is now analyzed, will "link popularity"
and "popularity of links" and Title - keyword order be as much of a prority.
Will Meta Keywords and Meta Description Tags play the same role in Inktomi (Google is now acknowledging Meta Description Tags).
Any updates or analysis anyone could bring would be helpful to all SEO's if there are any changes to Yahoo search.
Even if Yahoo continues it's relationship with Google, the fact the MSN and HotBot uses Inktomi will still put the information to good use!

Good points AAAAA. Even though we have no idea how Yahoo will use Inktmomi, it seems most people are preparing for this by starting to optimize for Ink again.

From my epxerience, Ink is using link popularity extensively. I think they also give a page points based on how long its been in the database. Plus the normal stuff - keyword density, keyword in all the important places, etc.

When I started my web site Ink was a pure PFI engine, so I completely ignored it. Since last August it has started spidering the web, and my site got included. I have made no attempt to "optimize for Ink", but my pages show up in roughly the same positions on the Ink and Google SERPs.

So I suspect that a site optimized for Google should do well in Ink with no further work.

Google prioritizes EXACT keywords in Title (no stemming)

and Exact KeyPhrase or Keyword Order in the Title.

Google EXCLUDES words like: the for etc. in the ranking Algorithmic results.

(Pictures Beatles will yeild a much different result than Beatles Pictures or Beatles Picture)(Beatles will yeild the same as 'The Beatles')

Also, Google demands that EVERY.
word in the query be on the Resulting WebPages, with very very few exceptions. .

Additionally, looking at Google's Adwords Keyword Suggestion
Tool, there are substantial difference in the Overture's Results (which focus on Yahoo Msn etc)

Also, will a Dmoz Listing have the significant effect that it currently has on Google.

Lastly, if Looksmart declines in popularity - Inktomi's results will graduallly become more important on MSN (the third most used search service) - the combined result could make an Inktomi listing more or equally valuable as a Google Listing.

Hey aaaaa,

"Also, Google demands that EVERY. word in the query be on the Resulting WebPages, with very very few exceptions."

Check the cached pages on Google. It is common to get this message -

"These search terms have been highlighted:

These terms only appear in links pointing to this page: "

In fact, it is not that uncommon to find pages without ANY of the words in the query on the page. The secret is anchor text. Very important point to remember when it comes to Google.

Regards

Google now uses Meta description and alt tags in it's ranking prioritization, I have noticed that in many instances (view source) I have found the words there.

Google also has an interesting "result":

if there is more than ONE space between two keywords in a Google Search - the results are sometimes slightly different...

Also, when doing an "Advanced Search" on Google you will often get more site (usually extra webpages belonging to a particular site - than you get doing the default 10 results-per-page. So a given webpage may be several places further down in the results.

Additionally, Yahoo, Aol, Iwon etc. are usually limited to offering "WebSite" results (compact) while a Google search will sometimes "pull" webpages with lower pagerank up right under the main page for a given search result if the title is similar.

Lastly, Geocities sites that have nothing to do with one another will often benefit from this - but - be absent from Yahoo, Aol etc for the same search - because they are programmed as being "WebPages"

:) adwords.google.com/select/main?cmd=KeywordSandbox

compare Google's keyword suggestion tools that searches Aol and Google among others to...

:) inventory.overture.com/

which searches Yahoo Lycos HotBot Msn among others

The results are extremely valuable for complete search engine optimization and also interesting to see the differences in the keyword search frequencies of their searchers

GOOGLE recently has added a new database center (number eight)

[aaaaa]

Inktomi Corp. scheduled a special meeting Yesterday for its stockholders regarding its merger agreement with Yahoo! Inc.
Yahoo! plans to buy Inktomi for $235 million, or $1.65 per share,

[running scared]

aaaa - you trying to rack up those post numbers quickly ;)

Interesting point about different key phrases used by users of the different search engines. Multiple multiple word phrases are very common on Google. Could optimisation of Ink mean having to concentrate on shorter phrases more? Will Yahoo users already be learning to go for longer phrases as a result of having Google SERPS?

[aaaaa]

A new flaw in Google Search

Google ignores common words and characters such as "where" and "how", as well as certain single digits and single letters, because they tend to slow down your search without improving the results. Google will indicate if a common word has been excluded by displaying details on the results page below the search box

placing the word "and" between two search terms will give you significantly different results.

Googles' ranking algorithms then change dramatically.

Japan's Largest Portal Joins Google's Growing Sponsored Links Distribution Network

MOUNTAIN VIEW, Calif. -- November 18, 2002 -- Google, developer of the award-winning Google search engine, today announced that Yahoo! JAPAN will join Google's network of Japanese advertising partners. Google will also continue to provide Yahoo! JAPAN users with web-wide search results, including more than 100 million Japanese language web pages, for search queries conducted on www.yahoo.co.jp.

Yahoo! JAPAN users will soon see sponsored links provided through the Google AdWordsTM advertising program.

with Overture purchasing AltaVista , and AllTheWeb

if Overture uses the same format that it has used with their Go.com, Excite.com, WebCrawler.com

(using their listings FIRST , then Inktomi second)

Inktomi may be POSSIBLY powering:

Lycos
AllTheWeb
Yahoo
AltaVista

Google was granted a patent by the United States Patent Office for a method of determining the relevance of Web pages in relation to search queries.
The patent, filed on Jan. 30, 2001, and was granted Tuesday.

Google turns up an initial set of documents related to the keyword and then ranks each page with a "relevance score." Next, it calculates a

"local score value" that quantifies "an amount that the documents are referenced by other documents in the generated set of documents

. Finally, the local score values influence the relevance ranking of a page.

"a search engine modifies the relevance rankings for a set of documents based on the interconnectivity of the documents in the set. A document with a high interconnectivity with other documents in the initial set of relevant documents indicates that the document has 'support' in the set, and the document's new ranking will increase. In this manner, the search engine re-ranks the initial set of ranked documents to thereby refine the initial rankings."

this topic was spidered and is now #17 on Google, for the term "google ranking"

Does that mean that this methodology is patented, or simply the underlying (and hidden) algorithms they employ to perform searches using that methodology?

Extrapolation Methods for Accelerating PageRank Computations

2003

We present a novel algorithm for the fast computation of PageRank, a hyperlink-based estimate of the ``importance'' of Web pages. The original PageRank algorithm uses the Power Method to compute successive iterates that converge to the principal eigenvector of the Markov matrix representing the Web link graph. The algorithm presented here, called Quadratic Extrapolation, accelerates the convergence of the Power Method by periodically subtracting off estimates of the nonprincipal eigenvectors from the current iterate of the Power Method. In Quadratic Extrapolation, we take advantage of the fact that the first eigenvalue of a Markov matrix is known to be 1 to compute the nonprincipal eigenvectors using successive iterates of the Power Method. Empirically, we show that using Quadratic Extrapolation speeds up PageRank computation by 25--300\% on a Web graph of 80 million nodes, with minimal overhead. Our contribution is useful to the PageRank community and the numerical linear algebra community in general, as it is a fast method for determining the dominant eigenvector of a matrix that is too large for standard fast methods to be practical.

[dbpubs.stanford.edu:8090...]

Topic-Sensitive PageRank

2002

In the original PageRank algorithm for improving the ranking of search-query results, a single PageRank vector is computed, using the link structure of the Web, to capture the relative "importance" of Web pages, independent of any particular search query. To yield more accurate search results, we propose computing a set of PageRank vectors, biased using a set of representative topics, to capture more accurately the notion of importance with respect to a particular topic. By using these (precomputed) biased PageRank vectors to generate query-specific importance scores for pages at query time, we show that we can generate more accurate rankings than with a single, generic PageRank vector. For ordinary keyword search queries, we compute the topic-sensitive PageRank scores for pages satisfying the query using the topic of the query keywords. For searches done in context (e.g., when the search query is performed by highlighting words in a Web page), we compute the topic-sensitive PageRank scores using the topic of the context in which the query appeared.

Google is possibly no longer displaying the recent date
that a given Web Page had spidered - when it has been spidered in the last two days...

You can however, use the "daterange" query to find out when a site was last spidered and which links to the site was last spidered...
