Problem is you can't set placement specific bids using a auto campaign... Any fix to this?Maybe run keyword campaigns and block out all the domains of the placements that aren't the one you're trying to target?
Just cut google out and hit them up directly.
PROTIP: Plug the URL of the placement you want to target into the Google Keyword tool. Take all of those keywords, put them into a new ad group. You'll show up on the site for much cheaper than placement targeting.
When placement targeting, your bid X quality score has to be higher than all of the other ads in that AdSense block combined. Keyword targeting, you just have to beat 1 ad in the lowest position.
