Yes but you may run into a problem. When users click you link or go to your aff url to sign up Party will ask them for a bonus code when depositing. I would say that close to 90% of your visitors will turn around and Google a party poker bonus code. Then they put this code in and that site gets credit for the player and the commision.
For Party the bonus codes are very important. Almost everyone will go searching for a code even if they come from your site.
If you really want to cut down on that list your bonus code directly under your URL/banner. It may help a little. Or try your ass off to get listed high on Google for Party Poker Bonus Code. That would be hard though if your site is newer.
