There are a couple easy fixes that you can do to help you if your site has been bit by the Penguin.
And I am guilty too, so if you look at this site, I repeat a bunch of words in the category links. Hopefully by the time you see this it is fixed. Mr Penguin says, "So stop the incessant repeating of words."
As far as the links coming into your site, you probably have the same anchor text repeated over and over.
Instead add links that use the following as anchor text.
- Your URL as so: www.yourdomainname.com
- Click Here
- The Title Of Your Website
This will help to dilute the over use of your main keyword in your links.
