I have had a website that did not make much until I added some MarketHealth links. My site comes up number one in it's market, gets hundreds of visitors/day. Not every one goes to my MH links of course, but of those that do, 1 in 60 buys. That's been standard for about 3 months.
In the past there were some complaints about sales skimming, and this may be going on now. It's impossible to tell. I am happy for the conversions I get, of course I always want more.
The other compaint is from people who haven't read MH's explanation of the tracking cookie and how to rid of it on your computer, so you will see your own number on your own click-throughs.
The AM has been very good at helping me with my site. Payment always comes through on time. Happy I am.
