Google just browses your site following hyperlinks that appear on pages. So on the openacs honmepage, for example, there are links to messages on the forums which google can retrieve.

Google can't login to the system though so it can only see content that is available to non-registered users.

If you click on the name of a poster on this forum you will not see their email address if you're not logged in and neither will Google.

As a developer you can detect if the visitor is Google and either block it or server it different content etc.

This is called cloaking and will most likely get you blocked from google indexing totally, because they test from time to time with non-detectable user-agents and ip addresses to see if you are serving the same content to the indexer and to the users, and if not then they assume that you are trying to cheat them.

They have actual people do this and if they see that you are only trying to serve the page in a way that is more google friendly they will most likely not blacklist you.
