How do I specify exactly which ad I want in a certain topic on my forum?

OK, so one of my topics in my message board is pretty high up in the search engines. Is there any way that I can get google adsense to display a banner that specifically relates to that topic? The topic is about a specific diet pill, and there are websites abound selling it....however I don't know if it's more lucrative to become an affiliate of someone who sells it?

I get about 45 google organic referrals to this diet pill topic daily, and about 75 page views a day.

 

Without the topics looking weird, it will display if its going to, but you cant exact any ad.

 

you can't select the advertisement but you can banned any website that you hate a lot for some strong reason

 

There is no way to do that for there are always higher bidders for a certain products.. if your compeny is the highest bidder then you will get 10% possibility..LOL

 

You can't tell google to specify a select banner showing a particular ad in your page. However, you have more chances to get a kind of ad displayed in the banner if your contents revolve around a particular type of keyword

 

Try section targeting
