Swapping the welcome deposit-bonus for cashback held conversion and cut bonus cost 33%

Operator A/B on 7,400 first-depositors, casino, 75-day tracking.

Deposit-match bonuses pay out upfront to everyone; cashback only pays losing players, which structurally favors the operator.

Group A — 100% match up to $100: signup-to-deposit 36%, bonus-cost/NGR 28%.
Group B — 15% weekly cashback, no upfront match: signup-to-deposit 34%, bonus-cost/NGR 19%.

The two-point conversion dip was real but small — the headline match clearly does some acquisition work. The bonus-cost saving (−33% relative) more than covered it.

The retention twist: cashback group's day-60 retention ran 24% vs 20%, because cashback gives losing players a reason to come back next week, while a one-time match gives no ongoing hook.

Net contribution margin/player: $88 (match) vs $107 (cashback), +22%.

The honest limit: in markets where every competitor screams "100% bonus," dropping the match outright cost more conversion (tested separately, ~5 points) — there, a small match plus cashback beat either alone.

Benchmark of the day: recurring cashback typically beats a one-time deposit match on both bonus-cost/NGR and day-60 retention — but keep a token match in match-saturated markets.
