First of all, Interest-Based seems to be a low ctr, however they do pay well. This is probably because Google wants the higher paying ads following people around, not the 5 cent clicks.

Placements pay very well for us with a decent ctr, just slightly lower ctr than the contextual ctr.

How can we see who are the "Placement" advertisers? I promise not to approach them directly!
