[adsense ads do not show up]

1) Have you checked the cache?

2) Remove your tag and replace it with something like: <div id="test100">TEST</div>, see if the word TEST shows up.

[Detect empty banners]

I'm using ad tags from a third-party and I want another zone and specific HTML to be displayed when the banner is empty.

Is this possible with Revive?

 

Edit: to make things more clear, as most of you know sometimes the tags don't show any ads due to various reasons.

I want to detect this and when the page is empty, a small piece of HTML (provided by me) should be shown along with another zone.
