What are the Best AdSense placements in forum?

I have read several articles and seen the heatmap. But this is based on ordinary websites. Can you provide me suggestions what the best placements are in a forum list and in a thread?

Cheers!

 

Forums specifically get repeat visitors, meaning that they are more prone to banner blindness. With that said, the "best" ad placement is going to be different for each site, as each has unique users. At Ezoic we have found that testing many different ad placements and using the data from user interaction is the best way to maximize your revenues. If you try more aggressive ad placements and it doesn't harm UX, those ad placements are sustainable long term. If it hurts UX metrics, best to try new ad placements.

 

Of course on forum the best ad placement is within the messages.
What I did is for each discussion page, I take the first 3 messages and I put 2 adsense in each :
- One adsense ad in a floating div at the top of the message, so the text wraps around it (either float left or float right)
- One adsense text link after the message and before the user's signature

So for a discussion with several pages, on each page the first three messages have adsense.

I tried to put adsense in the header, in the footer, in between messages, it doesn't work well at all !
