Last May, Google introduced Webmaster Academy, a program designed to help would be webmasters learn what they need to know about getting a site up and running with Google. This includes information about how Google Search works, how to create a site, and how to use Google's diagnostic tools like Webmsater Tools.
The program is divided up into short lessons, which let you track your progress (not entirely unlike Khan Academy).
Until now, Webmaster Academy was only available in English. Today, Google announced that it is launching in 20 new languages.
"The Webmaster Academy was built to guide webmasters in creating great sites that perform well in Google search results. It is an ideal guide for beginner webmasters but also a recommended read for experienced users who wish to learn more about advanced topics," says Giacomo Gnecchi Ruscone from Google's Search Quality team.
Webmaster Academy is accessible from Webmaster Central. You can see the full language list at the bottom of this page.
