There are two different ways to go in order to get a player tracked under you. Either by a refferal link or by a bonus code.

The tricky thing about using only a refferal link is that links are using cookies. So if a player visits another affiliate site before your site and clicks on a link a cookie file will be stored on his computer. 2 hours later when he gets to your site and decides to sign up though your link he still might be tracked under the previous site because of the cookie in his computer.

Usually bonus codes overrides referral links. Use both to be on the safe side.
