Ok so I know about the majors; Google, Yahoo, MSN. I want to know if anyone has an experience utilizing any other networks besides those. Has your ROI been worth it? Does there appear to be click fraud? What are the min bids.
I'm looking for networks with low min bids on key terms like .01-.05. If anyone knows where there are networks that give you free credit to start promotion that is even better.
I appreciate all feedback good and bad.
