Google has launched a new resource named Webmaster Academy.
This is a resource to teach small businesses the basic of how Google search works, ranks content and how they can improve their web sites.
Vanessa from Google Places Help said this is what to expect:
An explanation of how Google Search works
How best to represent a brick and mortar business online
An introduction to Search Engine Optimization
There is some pretty useful beginner content on the Google Webmaster Academy so check it out and recommend it to some newbies.
