Inserting google adsense in the part of the site with closed access (authorization)

Question

Google

Good day to all

Please tell me, because I just started to deal with google adsense:

1. Can adsense advertising be built into the site on internal pages, i.e. requiring registration + authorization?
2. Can adsense ads be displayed dynamically, i.e. at a certain moment, for example, as a popup on a page? And if so, is there a restriction on the display? It is necessary to show ads 2 times during the user's work. PS, is it possible to hide two blocks in which there are ads and then show them as popups or will it be a modification of the code?
3. Is there a javascript api for this?

Answer 1

the first one is definitely possible, the rest I don’t know

Answer 2

The answer to the first question is yes. You just need to create a separate login for the AdSense robot. See help for details .
