List of PPC Search Networks

I'd like to make a list of all the different PPC networks that have showed promise. I won't include the big 3. Please reply and I will update the OP. Where possible, I'd also like to include the type of demographic and the scope of the advertising.

1. Looksmart
2. Marchex (GoClick/AdHere)
3. AdSonar (Quigo) - (Huge companies like AOL, NYTimes, Fox)

Tons of impressions, low CTR (I think it has to do with the placement of the advertisements - placed on AOL and NYTimes currently. Testing different ads to see if this helps. Clicks that are being received don't convert to the merchant.. targeting is an issue on general traffic sourcing.)

4. FindIt-Quick.com
5. 7Search
6. Pulse360 (Moniker/Kanoodle)
7. Youtube PPC
8. Myspace PPC

18-24 Male: high daily volume, but not converting to the merchant lander, this shows that the clicks are either not on purpose or just happy clicking. I'm going to pause this age group for offer 1.
9. Facebook PPC

10. Bidvertiser
11. FindWhat
12. Findology
13. Search123
14. Enhance Interactive
15. AmpKeywords.com
16. Text Link Ads
17. Go Wholesale
18. Miva
19. Ask.com
20. Search Anyway
21. JumpTap (Mobile market)
22. Copernic Media
23. Clicksor
24. Search Feed
25. Mama
26. StumbleUpon
