I'm wondering which placements work the best for you?
Personally, I only have 2 ads - ad_above_content and ad_below_content. I refuse to put ads in threads at all. Currently, I get the most clicks from the above content.
What is your experience? Oh, and this is not a discussion about Google adsense or anything like that. It's not about the ads themselves. It's about placement effectiveness for your forum.
