Here's what I've come up with.

Ok...been about 6 months in this biz now. And here's what i've come up with.

1. sponsors
a. pay per click
b. pay per sale/recurring
c. dialers
d. AVS
2. Ways to promote / site types
a. TGP's (your own or galleries)
b. AVS sites
c. Free site networks (100s of small sites with one portal page traffic monster)

Experimenting with all of these in the past 6 months has lead me to the following conclusions:

1. TGPs - using Dialers are great IF you have a MINIMUM of 60-100k a day. Mine was up to around 10k a day and I wasnt making but 10-15 bux a day.

2. AVS sites - Require lots of quality traffic to make any substantial income. Even if you say its a free after age check, people will not rip out the CC for shit. Therefore my AVS site with 3k a day was only generating 1-3 signups a day (using FreeNetPass)

3. Free site Network - Probably the best method i've found so far. I was making a site for every ARS niche (small sites with 2 galleries) and using my main site as a portal to them. I managed to get around 7-10 signups the first week using only 7 sites (cant imagine if i had one for every niche).

So...free site networks seem to be the best...make em..submit them...forget them.

This is just my opinions based on research i've done...feel free to add comments/etc if you like guys.
