Search engine optimization
Google blog search
The Google blog search, despite its name, lists any site with RSS or Atom feeds, which includes all the Moodle forums.
They will soon have a manual submission process but for the time being you need to ping a weblog update service.
Google site maps
Site maps allow you to tell Google exactly what pages you have and when your site changes. You do this by creating a 'sitemap' using a program you can download from them, or alternatively just point them at your RSS feed.
The opentogoogle variable in Administration >> Configuration >> Variables may be set to 'Yes' to allow Google to enter your site as a Guest. In addition, people coming in to your site via a Google search will automatically be logged in as a Guest. However, people can just read the content from Google's site without ever visiting your site.
Of course, the standard stuff applies:
- Making your content interesting
- Linking to relevant sites and getting relevant sites to link to you. Moodle donations provide a way of adding a link to your site from moodle.org.
- Getting bloggers in your field to talk about your site (this seems to be the current best method)
- Using of meta-tags in Moodle forum discussion
