This project was pretty tough. Exporting data from SQL into a variety of text formats is never simple. Each CPC marketing campaign engine has different requirements. One mistake or formatting error and the entire feed file gets kicked back out.
Compounding the issue is the delay in testing. Some of these feed engines take 24-48 hours just to tell you it worked or it failed. But at this point, I believe it is ready for beta with support for the following marketing feed files:
Yahoo Search Marketing
There are several more formats I will be adding, so if you have any suggestions please post here and I'll do my best to get them added. PriceGrabber.com is one I'll probably add.
