It's a night thought but until Google or someone they can buy out comes up with a level of artificial intelligence advanced enough to be able to comb through hundreds of thousands, possibly millions of competing pages related to the same search and determine which provide the best information, it ain't gonna happen. In fact, a human would have trouble doing this for even a small set of pages without extensive research unless they were familiar with the topic.
They do this now.
The Google system uses a form of LSI (Latent Semantic Indexing) to compare and evaluate not only the words on the page but the relationship of the words to one another.
This is one of the things that was done to the long tail in the Mayday update. Instead of allowing long tail searches to be ranked by exact match, as was done previously, the long tail searches were brought into the LSI type scoring.
The reason original search engines had indexes which were manually created by humans was because that was the best way to ensure quality. As the web grew that became far too limiting to be practical.
Keyword density based algorithms could comb through huge data sets but are easy to manipulate. That's why Google started using links as a major factor in ranking. The idea is that a link is a vote that a particular page is relevant enough to earn one. This allows links to act as a sort of human editing system. Now it's not perfect but it's just on in hundreds of factors modern search engines use.
The idea that a link is a vote worked until the SEOers figured out that search positions could be manipulated with links.
Google engineers quickly noticed this trend and continuous changes were made to the ranking algos. (From inception in '98 to June 2002, small tweaks were continually made to the ranking process with a minimum of 19 days and a maximum of 54 days between updates.
This has continued through the years and resulted in some major updates.
I have documented them in my "An incomplete history of the Google search engine from a SEOers viewpoint." article on nbs-seo
Real tests done by many authorities in the SEO and internet marketing arenas such as SEOMoz has shown that linking is still the biggest factor and that on-page factors are important but secondary.
Do you realize how out of date SEOMoz's articles on linking factors ARE?
They were published before Caffeine, Mayday and even before the removal of the PR tool from Google's webmaster tools.
Another factor in their keeping this myth going is because of all the software they sell for linking. They have 11 tools JUST for linking.
Lots of potential revenue loss.
Think that's crap? There are tons of examples of web pages that rank #1 for keywords that appear nowhere on them or on their site for that matter. So why are they #1? Because of anchor text in their off-site backlinks. If that's not proof that what the OP is saying is wrong then what is?
Please show me some m8?
Except for Google bombs, I have never seen this and I do literally thousands of searches every month.
The idea of "one link, one (weighted) vote" was a stroke of genius, at the time. I do not think Google anticipated the amount of link brokering and link manipulation that would result.
I imagine that fighting paid and non relevant links has cost them millions.
With both the Mayday and Caffeine updates Google moved away from having links influence search positions using a much more complicated (advanced) algo set which concentrated on the relevance between linked and linking pages.
They changed the algo for PR in Mayday and very few caught it when they replied to Vanessa Fox.
I asked Google for more specifics and they told me that it was a rankings change, not a crawling or indexing change, which seems to imply that sites getting less traffic still have their pages indexed, but some of those pages are no longer ranking as highly as before
Vanessa, bless her little Google heart, seems to have totally missed the point. (Or she is still being paid by Google to mislead the SEOers.)
She confuses rankings with indexing, 2 different things entirely.
Look at the words Google used in their reply.
rankings - crawling - indexing
rankings = PR - crawling = how often your pages are visited by the googlebot and indexing = the position in the serps.
The Mayday algo change affected the way PR is calculated.
It would not affect the way your site was crawled (The upcoming Caffeine update was going to do that).
It would not affect your indexing in the SERPs even if you lost PR.
(I had one
If links and PR had an effect on SERPS, they could not say a PR algo change would not affect your indexed positions in search results, as they most definitely would.
(Unless they are lying to us).(
