After correcting any problems on your site, you need to have Google rescan your site.
To get Google to re-scan your site please follow the below steps:
- Go to http://www.google.com/webmasters/
- First you have to add a file to verify his site as owned by you
- Then click the link (shown in image below) and follow the on-screen instructions “How to remove the message if you're the site's webmaster” under and re-submit saying all the files have been removed. When it asks you what you did to fix the problem you will just say “all the spammy links have been removed from the affected files”.
