I am creating a private Google site page for a university project, and only my project's teammates can access the site. (of course) But I want to make sure that everyone participates by coming to the site. Is it possible to check whether your private members access the site or not?
There's no automatic logging of the specific users that visit your site. You can, however, get general metrics from Google Analytics. If you need to know whether people visit a page, you could try requesting an action by all users which is logged. For example, they could comment on the page or submit a form.
