Google's Own Listing Hijacked On Google
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 ...
www.all-in-one-business.com/adsense/ - 16k - Cached - Similar pages
Notice the URL:
www.all-in-one-business.com/adsense/
That's definitely not Google's! Yet if you click on it, you end up at the official Google page, located here:
https://www.google.com/adsense/
What's happening? The URL that's listed is using a meta redirect command like this:
META HTTP-EQUIV="Refresh" CONTENT="0; URL=https://www.google.com/adsense/"
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.
