The number of conversions that MSN reports from their conversion tracking is about double of the actual number of conversons I have received. Has anyone else had a problem w/ inaccurate conversion rates supplied by MSN tracking? I can't seem to figure out why they would have such an inflated number of conversions?

Yes, their conversion tracker does track close to double the conversions. Always has for us... support has been of basically no help.

Do you have more than one conversion pixel in place, say like a Google or Yahoo tag? Say a user searches for "your product here" on Yahoo, visits your site, then doesn't convert. A few days later he comes back and does a search on MSN for "your product here," visits your site, and completes a purchase. We found for some of our efforts this was a nasty little double counting culprit.

Good luck!
