I need setup a pay per click campaign quickly Out of the three ppc networks which one would enable me to do this without building a landing page & the quickest review of the keywords for the quality score. Yahoo MSN AdWords or another ppc that would convert for direct linking to a CPA offer.
I have no experience with exoclick, but AdWords is always fast. The review of your ad, if any, comes after you're already running. And I've never had my keywords reviewed or held up like Yahoo does.
