Who would have guessed that one of the best ways to spam Yahoo would have been spamming Google?
Earlier today, Barry Schwartz posted on Search Engine Roundtable about the phenomena where Google is ranking well in the Yahoo UK SERPS for the phrase “Buy Viagra”. Sure enough, when I checked the results for myself, in the Yahoo UK SERPS, for ‘Buy Viagra’!
A little deeper research into the matter indicated quickly where the source of this is quickly apparent. Perform a quick search on Yahoo for the phrase ‘buy viagra’ while constraining the search to the Google.com domain.
The first thing you will probably notice about the 37 SERPS returned is that there are a bunch of pages written up in full of pill-spam. These notebook pages are full of non-nofollowed links pointing to further spam sites.
This is extremely ironic, considering how Google pushes the NOFOLLOW tag to be used for user-generated content. Perhaps they should look at what they are allowing people to post on their domain?
Examples:
Secondly, there are a number of attempts to gain links through Google redirects, which are indexed by Yahoo!. This generates more non-nofollowed links on the Google.com domain. Again, ironic lack of NOFOLLOW tags on Google’s part…
Examples:
Lastly, there are various other pages linked in there, such as the Zeitgeist, a CSE for viagra purchases, and a link to Google trends.
Now, I highly doubt that there are thousands of sites out there linking to Google with the anchor text ‘buy viagra’. As a result, I don’t think it would be a stretch to suggest that the main thing propelling Google near the top of the ‘buy viagra’ SERPS in Yahoo would be these keywords on Google’s sites.
Building off of this, I would suggest that Yahoo places an unbelievably high value on the Google.com domain. Since the fact that those keywords only appear on 37 seperate pages on the Google domain was enough to push Google.com quite high in the Yahoo.com SERPS, I suspect that if one was to load as many pages on the Google.com domain (thinking of Google Base and Google Notebook, in particular), it would be possible without too much effort to rank for competitive terms in Yahoo.
I await your thoughts on the matter!
