Can Yahoo manipulate Google's SERPs?

Is this not bias

[shaadi]

When searched for "Search Engine" (without quotes) on Google, Yahoo, Inktomi. All the three SERPs differ. How can Yahoo manipulate Google's SERPs? Is this not bias.

Inktomi
[search.positiontech.com...]

Yahoo Search #10

Google
[google.com...]

Yahoo Search #3

Yahoo
[search.yahoo.com...]

Yahoo Search #1

With Google #2 and clearly Google's SERPs are manipulated.

This is interesting. I see the same results that you noted, but notice that on Ink, the listing is for www.yahoo.com, and on Yahoo, the listing is search.yahoo.com.

Don't forget:
[search.msn.com...]

I've seen this on a variety of SERP's.

I have a site that recently got banned from Google, yet it is ranking in Yahoo in the top 5 for a single word.

I think Yahoo is applying its own filters to the data based on the other search engines they own. The site in question has a massive amount of backlinks in Alltheweb, Altavista and Ink, and I think Yahoo is keeping it in their SERP's as a result.

Personally, I subscribe to the belief that Yahoo has created their own algorithm that is applied to all their databases. I think it'll be a compilation of the results of all 3 databases, without them distinguishing where the weight is being applied.

This would be a very difficult algorithm to break.

2_much, that sounds very intresting.

Yahoo has been manipulating Google SERPs for a long time (It started in May 03 as memory serves)....See [webmasterworld.com...]

Note that they only manipulate their SERPs when the default 20 results per page are used. Use Yahoo Advanced Search and set the results per page to 100...now you have clean Google results.

I don't see why this is biased? Google SERPs are only an opinion of Google, Inc., Yahoo SERPs are an opinion of Yahoo's.
