The first thing is to read the rules of the affiliate program clearly. Some programs don’t allow certain kinds of redirects, especially if you try to hide where the traffic is coming from. You should always use the correct tracking links they give you and avoid using double redirects or masking unless it's allowed. If you change the link too much or use redirect methods they don’t like, you can lose your commissions or even get banned. It’s always better to be safe than to risk your whole campaign. Have you seen redirect issues affect performance or accounts before?
