I am new to the PPC world and the company I work for just became an open network 2 months ago. Prior to this we were a closed network and would only show certain networks or mailers our offers. We wanted to expand and allow PPC and SEO traffic for particular offers. At 1st traffic thru PPC was flowing in and then BAM! A lot of the PPC affiliates that signed up to our network were scammers approved by us only after speaking to them on the phone. We have learned the hard way. We lost 3 advertisers within 4 days of each other. We have now learned a better way to screen thru these applications (takes too much time in my opinion) and some of these look legit. But the fall back is our CEO has now put every offer we have on "Request Approval" which just takes time for the legit PPC person and our networks and mailers to get things going. What i am asking is a little advice on screening PPC from all you legit and honest PPC players.
