Avelyn Austin and I recently recorded a webinar entitled Google Sitemap Basics. Check out the Search Mojo YouTube channel to view this webinar, as well as past webinars hosted by Search Mojo.
Google Sitemap Basics includes information about general Sitemap and Sitemap Index components, along with information on how to generate them, and register with the search engines. For convenience, the recording can also be viewed below.
Next month, we plan to release a webinar recording involving Specialized Sitemaps.
