Has anybody met this problem before? I have a website where I place three ads unit in 1 page. For some pages only 1 ad unit is appearing and the ads are not related to the content. At first I though it was because I didn't had a lot of content but now I added more content and the problem persisted! I am using mod_rewriting does that affects google adsense!?

anybody had the same problem?

patience!
4 hours isn't a lot to wait for someone with an answer.

It simply means there isn't enough advertisers to fill the other units.

OKi chrishirst thanks loads :-) sorry for the impacience:-)

If the ads are irrelevant means that the content of your page does not interest many advertisers.

Inside a homepage should better not put many similar ads!
