Hey guys, this is my first time posting. I am looking into ppc ad networks. I have had some success with AdWords but have had zero success with networks like ezanga. I am looking to display my ads on a site with good conversion rates. Most likely I will be doing ringtone campaigns and dating. I am thinking about using Chitkia, Oridian, Pulse360, SearchFeed, Miva or Enhance Interactive. Looking for some of the experienced guys and girls to let me know if these are good choices, and suggest any others. Thanks!
