Innovation Google SEO Tools
I figured I would write about this cuase I know there is a lot of people out there still learning seo, and I figured this would be another good tool for any one that is a google junkie, matt cutts actually talked about this tool in his video at Matt Cutts Google Tools. He disucssing exactly the tool do, and what to use them for, and how to be used which he sounded very excited about this.
What these to Google web master tools do is support multiple features, and it will tell you when you have been penalized for something, and what need to be cleaned up.
