How does Google defined of a spam website?

If you see this message on the Manual Actions page, it means that Google has detected that some of your pages may be using techniques that are outside our Webmaster Guidelines. The site appears to use aggressive spam techniques such as automatically generated gibberish, cloaking, scraping content from other websites, and/or other repeated or egregious violations of Google?s quality guidelines.


As a result, Google has applied a manual spam action to the affected portions of your site. Actions that affect your whole site are listed under Site-wide matches. Actions that affect only part of your site and/or some incoming links to your site are listed under Partial matches.

Google?s Webmaster Guidelines outline best practices for website owners, and the use of techniques that violate our guidelines may cause us to take action on a site. However, not all violations of our Webmaster Guidelines are related to content created intentionally by a site?s owner. Sometimes, spam can be generated on a good site by malicious visitors or users. This spam is usually generated on sites that allow users to create new pages or otherwise add content to the site.


If you receive a warning from Google about this type of spam, the good news is that we generally believe your site is of sufficient quality that we didn?t see a need to take manual action on the whole site. However, if your site has too much user-generated spam on it, that can affect our assessment of the site, which may eventually result in us taking manual action on the whole site.


Some examples of spammy user-generated content include:


Spammy accounts on free hosts
Spammy posts on forum threads
Comment spam on blogs
Since spammy user-generated content can pollute Google search results, we recommend you actively monitor and remove this type of spam from your site. Here are several tips on how to prevent abuse of your site?s public areas.
