I started playing a bit with Google custom search engine, and created this simple
Adult Sponsor Search Engine, which basically performs a google search limited to 800 adult affiliate program domains.
The idea is to get better search results by targeting only relevant sites, and excluding all others. Obviously it can't replace hand made affiliate program directories etc, but could still be an useful tool for affiliates.
Would like to know if anyone finds this kind of tool useful, or if you have any ideas how to make it even more useful.
