Google has updated its webmaster tools section this week with a new toy called keyword significance. Even though it hard to tell what you can really do with this data it does give you some good insight on how Google interprets your sight and this will help in your SEO optimization. In Google’s post they talk about how the tool should help you with your site:
“This will be really useful when you re-implement your site on a new technology framework, or need to identify which URLs may have been hacked. For example, if you start noticing your site appearing in search results for terms totally unrelated to your website (for example, “Viagra” or “casino”), you can use this feature to find those keywords and identify the pages that contain them. This will enable you to eliminate any hacked content quickly.”

If you read one of my last posts about how Google now offers malware alerts you can really see how this new tool and their last ones are starting to help protect the website owner. I love the new how Googlebot sees your website tools as this gives you some great vision into your SEO organic strategy.
