I'm building a large authority site the site is pretty new, but it already had 17 or so articles on it between 500 and 1,500 words in lenigh all with custom images created etc. Even though there's not much traffic I thought I'd install Adsense to get that out of the way, the ads started displaying instantly for around 3 days after I installed them. Then I checked today and they're not displaying and there's just white spaces were my ads are supposed to appear, does anybody know why this is happening? Is this normal practice? I've never given Adsense attention in all my years of IM, so even though I understand it I don't etc.

I'm complying with all their TOS, and I have their privacy policy installed and easily accessible.

Thanks for your help.
