The Google Webspam Report extension allows you to report spammy webpages which ranks high in the google search results but contains questionable content. And in fact, any webpage that appears to be spammy can now be reported easily.
According to this page on Google Webmaster, you can report a spam page if it has one of the following “problems”
– Hidden text or links
– Misleading or repeated words
– Page does not match Google’s description
– Cloaked page
– Deceptive redirects
– Doorway pages
– Duplicate site or pages
– Paid links
If you use Google Chrome, you will see a new “Report Spam” link on every search result listing after you install the Google Webspam Report extension. It will also allow you to report any webpage.
Black hat and dodgy webmasters beware!
