A unique hit is when in the above scenario only 1 hit will show up instead of 5 in your stats. Same surfer clicks through 5 times, only 1 unique hit shows up. Most programs show both unique and raw. We do. (CCBill's script does not)

The above rules apply to all the tour pages. Some sponsors report all and some no. You can have:

1st page raw
1st page unique
2nd page raw
2nd page unique
join page raw
join page unique

etc etc

A qualified hit means that after the surfer clicks your link and you send him to the tour, he then clicks again to the second page. Some might also report a qualified hit only when they click through to the join page. Depends on the sponsor and the tour. (tour might only have 2 pages for example)
