Understanding the Google Webmaster Guidelines
If you care about your website ranking in Google search engine results, you must read and understand the Google Webmaster Guidelines. However, for most non-techie site authors such as bloggers, the guidelines is hard to understand.
Feedthebot is a site dedicated to help you understanding the Google Webmaster Guidelines. It provides a detailed look at each guideline by defining the terms that are used, explaining the concepts and providing examples of common violations.
I highly recommend it to every webmaster and bloggers!
