I have a site that is private and only registered users can view the content.

I installed the plugin Advertisement and create a account on Google Adsense. Add the code in the plugin. That all ok.

But as a private site, I believe Google don't can't access the site too. Because don't appear any ad in the site and Adsense can't confirm if the code is on the site.

In Configuration (Adsense) there is a form to add a login account for allow the Google access the site content, but I don't know how fill it.

I have tested many options, but do not work.

Can someone help me?
