If you don't like interest-based ads appearing on your site, you can try turning them off.

(Or at least you could a few months ago, because I did).

I found that EPC fell slightly, and CTR didn't change - so my EPM ended up lower.

I was surprised by that result - but that's why it's worth testing.
