I know we can use gravity as somewhat of a proxy, but the thing that is missing with that is the volume of inbound hops. A product could have high gravity (ie: decent sales), but it could be because affiliates out there pushing it with massive lists, etc. So, yah, 300 or so distinct affiliates made a sale, but is that a guarantee of high conversion? Is the data available anywhere (like maybe CBEngine PRO)? I've had moderate success with the few CB products I've marketed, and am looking for the next one. (Me and everyone else, right?)
The only tool that will show you conversions is the one that will hack into clickbank's databases. But what you can do is sort ClickBank products by their monthly visitor counts Hope this helps
You can simply ask the publisher. If you think there are some affiliates that use high converting methods (like email lists), ask the publisher to exclude them from the conversion ratio calculation. nadavs
