bl4ckmaN^, YSM and AdCenter are both completely open for Water For Gas products. We are getting a lot of sales coming from YSM and AdCenter traffic. We are also seeing quite a few sales from Google PPC as well. Adwords isn't allowing phrases like "water for gas" or "run your car on water" but they do allow a lot of other related words/phrases (e.g., "water powered car" or "hydrogen fuel"). These longer tail keywords are much cheaper and seem to be converting better (for our affiliates). I ran a quick campaign with the $75 AdCenter credit and did pretty good considering I'm a PPC novice. I'm not running anymore because I really don't want to compete with our affiliates. You should definitely be promoting this niche as it is pretty much easy money. We have a couple of affiliates who are just killing it right now with our product. Just running the numbers, they're grossing well over $500-$1000 a day (Tuesday was way bigger). Did you see my thread on 100% commissions? http://forums.digitalpoint.com/showthread.php?t=882692 PM me if you have any other questions or want me to look over your campaign. Scotty
