I recently read the ad balance slider post and adjusted my settings down to 70%. I could even go down to 60% while remaining at 100% earnings however now that there is a lot more empty space I would like to enable Amazon backup ads to display cookie-based backups ads. I notice when I go to other sites I see lots of Amazon ads related to products I was browsing previously which I assume is tracked via cookie. Is there any option to display these ads as backup ads to Adsense?
I signed up with Amazon and see they have something called "Native Shopping Ads" but that seems contextual (which would have no use on my site) and I would like ads displayed based on cookie. Is this possible?
