Seems we all have the same problems
What I can say in few words is:
1. NICHE - The less 'usual' niche, the more signup willing surfers
2. SOURCE - 100k hits from Worldsex is not 100k form The HUN (HUN is really easier converting, however there seems to be also sponsors converitng WORLDSEX traffic)
3. LINKS - If you link the sponsor with blind links You will get higher click-through ratio, but NO signups. I use to say the truth to surfer (that he has to pay)
4. SPONSOR - This is what have you to try for yourself: For me working last two months:
AP (1:100 this month, average about 1:800)
DJPRODUCTIONS (1:1000, first-page ratio)
5.RECURRING or PER SIGN-UP : For TGP I would like to take my 30-40 bucks /signup and run away, I think TGP surfers don't stay too long with any program.
My 2 cents
