Nice!
Was that a paid spot or free? You should still see some sales for another week, and then sporatic ones in the archive... ;)
Thats about normal, CTR on tgp is generally 1-4% you could say you are in the middle, or above average.
Galleries like milf hunter, etc, that are REALLY popular, and really spent some time building them, get higher ctr's...
Good job on ur first gallery on the hun tho
