Is this a common tread for stats with sponsors?
 

For years i did only webcams and dating sites. So those sponsors dont show 1st page, 2nd page and join page hits. Now im pushing i guess you would call it mainstream porn and looking at stats for a particular sponsor. The join page hits are double of the 2nd page hits is this common?

It CAN be common depending on the tour and how the sponsor counts join page hits.

For example, if the sponsor counts raw join page hits, PLUS has lots of links (blind especially) to the join page, then it could be entirely normal.

There are also cases where the tour is heavily laden with sample movies etc. Where you may get a surfer browsing tons before clicking the one clearly marked Join link. Resulting in really LOW join hits (but perhaps exactly as productive).
