Pay bump refers to the increase in the payout that affiliates receive for any particular offer. Generally, the affiliate managers fix a specific payout for affiliates when they start. If an affiliate could send targeted traffic consistently, increasing overall sales, the merchants will be willing to increase the money paid to the affiliate agent. All merchants would want their agents to be satisfied because only motive affiliates will work harder to increase exposure. Typically, the pay bump results in 5% to 10% increase in the regular payout. Some affiliate managers provide pay bump as a reward after achieving a tough target.
