The easiest and most common answer would of course be Adsense. It's simple - just place and forget. But I believe you can still squeeze a lot out of your visitors by doing more. What would you do? CPA definitely does not work and converts crap on informational site. After all, information is free. Tried adding Amazon too but earned my pennies, Adsense was making 100x more than what Amazon would make me. Clickbank isn't exactly the best either (somewhat like Amazon) unless it's a review site. So what would you do? I have a few informational sites that I plan to use Adsense on them but was just thinking how I can use them to their maximum potential. Any opinions\advice would be appreciated.
