A split is the percentage you keep versus what the agency takes for its work.
Deals often land between roughly 30% and 50% to the creator, depending on how much the agency handles. Promotion-only takes less; full-service (traffic, chatting, content) takes more.
Never compare splits by the number alone. A 30% split with strong traffic can pay more than a 50% split with none. Compare the work included.
Tell us a percentage split or a fixed amount, so the deal you want is clear from the start.
