@brian you need to ensure that the BP component Site Tracking is enabled. You’ll find this in Settings => BuddyPress. You may also need to allow search engines to search the site, this is found in Settings => Reading and select Allow search engines to index this site.

The site tracking is needed for BP to add posts and comments to the activity stream. As for the search engine indexing, I know that in times past, if search engines were blocked, then BP would track the site either. I don’t know if this was ever changed in BP so just double-check that setting.
