I'm using ebay's RSS feed creator, where you can insert your CJ PID into a certain feed. I have the feeds running on many sites and they're getting about 3 dozen clicks per day, and I have not made a single sale in 2 weeks off of them. How do you know if they're working?? I checked the URLs, and my PID number does appear in all of them. I'm just doubting that it works at this point. Even out of probability, at least one of those people had to have bought something!
I use ebay's RSS feed in a number of ways, including BANS. I can tell you with certainty that it does work. It may be that the traffic you have are lookers and not buyers.
Yes, it absolutely works Maybe post one of your links so we can have a look (**** out your PID if you want).
