Use both, in order. Gifting is cheap and great for awareness and for testing which creators actually deliver but you cannot demand a post, control timing or claim usage rights. Paid buys you guaranteed deliverables, usage and control. The smart play is a funnel: gift widely, see who performs and genuinely likes the product, then pay the winners for real campaigns. Gifting alone is not a strategy and paying everyone cold is a waste.
Use them as a funnel
Gift to test, pay to scale the winners. They work together, not either-or.
Gift for awareness
Cheap and wide but no guaranteed post, timing or usage. Treat it as a try-out.
Pay for control
Guaranteed deliverables, usage rights and timing. This is where campaigns live.
Pay the proven ones
Move creators who deliver on gifting into paid. Never pay cold.
