TripAdvisor closely monitors the overall value of the commissionable click-outs to make sure that the traffic converts sufficiently for our booking partners. If the traffic doesn't convert well downstream for our partners, we reserve the right to remove the publisher from the program.
Additionally, we continuously monitor for fraudulent click activity and commission is only paid on valid clicks. If TripAdvisor suspects a publisher to be unscrupulous we will need to pause activity for the publisher in question with immediate effect. The suspension will mean that the affiliate can no longer promote Trip Advisor whilst they are under investigation. If this occurs, all transactions for the month will be reversed and accepted/declined after further investigation.
