Tried searching, can't believe I cant find a thread on this.

Where to put the general adsense code? Not the ads themselves, I know how to do that. I cant remember where to put the Adsense code snippet that Google has to see in order to add my website to adsense. Please explain like Im five.

I tried the Snippet in advertisements, for platform, for forum, Google cant verify. Then I tried their Meta tag code, added it to meta tags, google cant verify that either. Im lost.

Keep in mind that there is caching in Cloud for guests (aka what Google will view as) so they likely won't be able to see it for a bit till that cache is refreshed.

If it needs to be in the head, the Google Analytics integration is good place to put it.
