My company's marketing manager spent quite a lot of time figuring out what we were paying adWords for. He quickly realised that most ads were displayed on eMule-related forums, and that most clicks we paid for were thrown-away money. Lesson learnt: track carefully where ads are displayed!

You can segment AdWords to only display on Google search results. And you should.

Yep, we realized it. The "Display Network" used to work fine, though. It went downhill in the recent years.

I think things were a lot better when AdWords was less expensive back in the day (say around 2003-2005).
