Common problems
Bidding on your brand name, toolbars that force a click, cookie stuffing and publicly leaked discount codes are the classics.
Often it isn't malice but unclear policy. Whatever isn't forbidden will happen.
Clear terms
Define what is allowed around brand bidding, email marketing, voucher codes, comparative claims and use of your logo and imagery.
Also describe consequences: a warning, withheld commission or termination.
Monitoring signals
Watch for partners with extreme conversion rates, very short click-to-order times, many orders from one IP, or a sudden spike without visible content.
Check where your codes circulate and search your brand name periodically in your main markets.
Returns and approval
Approve transactions only after the return window closes, so you don't pay commission on returned orders.
Communicate approval and payout timelines up front; vagueness there costs you good partners.
Compliance per market
In many countries publishers must clearly label affiliate links. Require it in your terms — it protects you too.
Check local rules per market on discount claims, price comparison and advertising to minors.
