Flat $ off, % off, BOGO, or a free-shipping threshold — each pulls a different lever on conversion and margin. CustomFit tests them head-to-head on live traffic and crowns the winner on profit per visitor, so you discount smarter, not deeper.
Flat amount, percentage, BOGO, tiered, and free-shipping thresholds — compared head-to-head on the same traffic.
The cheapest-looking offer often wins on conversion and loses on margin. We rank offers by profit per visitor, not raw CVR.
New visitors, returning customers, and high-intent carts can each get the offer that converts them best.
“$5 off” and “15% off” can be identical in value yet perform worlds apart, and a free-shipping threshold can beat both while nudging basket size up. The only way to know which your buyers respond to is to test the framings against each other.
Discounts move conversion, but the wrong one quietly torches your margin. CustomFit ranks every offer on profit per visitor and enforces a margin floor, so it never crowns a promotion that converts well but loses you money.
We assumed a percentage off would win. The free-shipping threshold beat it on profit per visitor and pushed AOV up at the same time — we'd have left that money on the table.
From a set of offers to a profit-ranked winner — no code.
Set up flat, %, BOGO, and threshold variants you want to compare.
Tell CustomFit the profitability line a winning offer must clear.
Visitors see different offers; we measure profit per visitor, not just CVR.
Promote the most profitable offer — or schedule it to a campaign window.
Discount A/B testing compares different promotional structures — a flat amount off, a percentage, BOGO, or a free-shipping threshold — on live traffic to find which lifts revenue most. Because the cheapest-looking offer often wins on conversion but loses on margin, CustomFit ranks offers by profit per visitor and enforces a margin floor so you never ship an unprofitable winner.
The right offer often costs less margin than the one you'd have guessed — testing finds it.
Threshold offers can raise AOV while still converting — a double win a flat discount misses.
Scope offers to new visitors so you don't discount customers who'd have paid full price.
Find the promo that converts paid traffic without eroding ROAS.
Rank offers on profit and ship the most efficient one.
Discount with a margin floor, not on a hunch.
Discount A/B testing compares promotional structures — flat amount off, percentage off, buy-one-get-one, and free-shipping thresholds — on live traffic to learn which your buyers actually respond to. Two offers of identical face value can convert very differently, and the framing often matters as much as the number.
The crucial discipline is judging offers on the right metric. The cheapest-looking discount usually wins on raw conversion rate — which is exactly why conversion rate is the wrong yardstick. CustomFit ranks every offer on profit per visitor (conversion multiplied by margin) and enforces a margin floor, so it never crowns a promotion that converts well but quietly loses money.
Offers can be scoped by segment — a first-order incentive for new visitors, a threshold nudge for returning shoppers — and time-boxed to a campaign window so they appear only when they should. Everything is built no-code and measured against a holdout, so you scale only the promotions that genuinely grow profit.
Flat amount off, percentage off, BOGO, tiered/quantity discounts, and free-shipping thresholds — all head-to-head on the same traffic.
The cheapest offer usually wins on conversion but can lose on margin. Profit per visitor (conversion × margin) reveals the offer that actually grows the business.
Yes. You set a margin floor, and the optimizer never ships an offer that converts well but falls below your profitability line.
Yes. Offers can be scoped by segment — new vs returning, by campaign, by cart value — so each audience sees the promotion that converts it best.
No. Marketers build and test offers in a no-code visual editor; developers can use the API and SDKs when they want deeper control.
