Google Compliance Slams Low Level Obfuscation

Recently I reported on what I considered a Google Adsense page that was basically “browser spam”- a page constructed to stuff the index with pages in order to redirect traffic through Adsense ads. The problem was the only content on the page was an Adsense ad.

Sorry my friends at Google but you knew it was coming. Here is one reason why merchant’s want granular control over where their CPC ads are placed. Pay attention Microsoft and Yahoo!

Note the use of canonical domain name: spywareremoval

Primary domain name: cnetspyware.com

And the hot button words in the sub directory: windows-xp-spyware

Lastly, and most importantly note the quality content…

It appears the powers that be at Google that read Revenews.com took the snapshot seriously.

If you visit the “content-rich” (cough) http://www.spywareremoval.cnetspyware.com/windows-xp-software you will notice there are no more Google Adsense ads being displayed. The page does sport a nifty obfuscated script which I may get around to de-obfuscating if I get bored. Based on analysis of pages in the MSN index I would hazard a guess the “content” is basically a low-level form of cloaking. To see how I make this logical deduction reference the MSN Index Results as of July 30, 2005:

http://search.msn.com/results.aspx?q=site%3Awww.cnetspyware.com

Note the titles, then hit the page and view source and you’ll be treated to similiar low-level obfuscation.

document.write(asdplf.toLowerCase());

Thumbs up to Google for a quick response but I would prefer a perfect world where these kinds of pages never make it into the index at all.

Now if Google wants to go the extra mile they might take the second step and simply eject the remaining two pages of this domain out of Google index and it would be just a little less polluted. MSN needs to get a clue.
