Matt Cutts (and his cat) explains in this video How to ask Google a Reinclusion Request after your site was banned from Google Results.
Matt answers the questions:
- How do I do a reinclusion request?
- What should I put into a reinclusion request?
- What does Google need to know before it reincludes a site in its index?
It is very important to register in Webmasters Google Tools.
Correct the reason that you think your site was banned from Google Results (Google will never tell you the reason).
Fill there a Reinclusion Request, you must apologize to Google, give very specific information about the mistake and promise that it is not going to happen again.
Matt Cutts is the head of Google’s Webspam team.
