Google’s Own Listing Gets Hijacked

I spent yesterday sending four or five emails with a reader who couldn’t believe that search listings on Google actually could get hijacked. Yes, I told him — they do.
Today, there was a great example to show him. Google itself had one of its own listings hijacked.

SEO DotComicide spotted this and posted with a screenshot. JenSense also has a screenshot and
a longer look here. I’ll do a summary below.

Search for adsense or google adsense on Google. What
currently comes up first is this:

Google AdSense
Google AdSense is a fast and easy way for website publishers
of all sizes to display relevant Google ads on their website’s
content pages and earn money – 16k – CachedSimilar pages

Notice the URL:

That’s definitely not Google’s! Yet if you click on it, you end up at the official Google page, located here:

What’s happening? The URL that’s listed is using a meta redirect command like this:


That fast redirect is being treated by Google as if it is a 302 temporary redirect. And in that case, it may substitute the page being pointed at by the redirect with the
address of the page doing the pointing.

Claus Schmidt did a bang-up explaining this in great detail back in March. See his Page Hijack: The 302
Exploit, Redirects and Google
for more on it.

FYI, Yahoo seems to have solved this problem by going against the way redirects are officially supposed to be treated. Barry Schwartz explains more at the end of this post:
Redirects and Rewriting

I heard from someone out at SES Toronto that despite this, Yahoo was still having problems similar to Google with redirection hijacking. However, I talked with Claus today,
and he’s not heard of this coming back as a problem. Neither have I. Which begs the question, if Yahoo can do it, why can’t Google?

For more background, see links in these past posts:

Want to discuss? You’ll find chatter at Threadwatch and
, as well as at our own Search Engine Watch Forums, in the Google AdSense Page
thread. That thread also covers how another site has managed to hijack the backlinks to Google itself. Instant PR 10 site!

Postscript: Google sent me this comment yesterday: “We are aware of the problem and working to remedy the situation.”
