Deterministic attribution,Meta to Amazon.
Your Meta ads drive Amazon sales you can't see. Bridge gives every buyer a single-use promo code and reads each redemption back through Amazon's own order data — joined to the exact ad set that caused it, every 15 minutes. Codes, not models. If the code was redeemed, the ad worked.
One board. Reds on top.
Every cohort is one offer tied to one ad set. The board sorts by True CPA against your break-even — and cohorts younger than 72 hours show grey, because early CPA always looks terrible and we don't call verdicts on immature data.
How the loop closes.
Five steps, none of them clever. Every one uses the platforms' own front doors.
A Meta ad meets a buyer
Traffic lands on a hosted funnel page — or your own lander wired to the Bridge API. One offer per cohort, one cohort per ad set.
The lead claims a code
Email required; phone optional behind a “text me my code” incentive with explicit, recorded TCPA consent. The single-use Amazon code arrives instantly by email — and by SMS only with that opt-in.
The code gets redeemed on Amazon
Codes are single-use: one buyer, one redemption. Each cohort's promotion carries a seller-defined tracking ID, created in Seller Central from a click-by-click runbook we generate for you.
The poller joins the loop
Amazon returns that tracking ID on every redeemed order. Our poller sweeps orders every 15 minutes and matches each redemption to its cohort — deterministically, through Amazon's own data.
You decide with real numbers
Spend ÷ redemptions = True CPA, judged against the break-even you set. Net revenue accounts for the discount, estimated fees, and Brand Referral Bonus. Green means scale. Red means kill. Grey means wait — the flight is under 72 hours old.
What Bridge never does.
Attribution products get sellers in trouble by being clever in ways platforms punish. Bridge is built the boring, durable way.
- No purchase-event leakage
Amazon-derived purchase data is never sent back to Meta or any ad platform. Meta receives only events that happen on our own funnel.
- No buyer PII from Amazon
We read order and order-item data only. No buyer names, no addresses, no PII — by hard product rule.
- No early verdicts
No red-or-green judgment before a flight is 72 hours old. Leads take time to redeem; early CPA always looks bad, so we don't let it lie to you.
- No consent shortcuts
Email always; SMS only with explicit, recorded TCPA opt-in and instant STOP handling. We've walked away from lists that didn't meet that bar.
Modeled vs. deterministic.
- The pixel loses the trail the moment the buyer leaves for Amazon
- The platform grades its own homework
- Lift studies and MMM answer last quarter's question
- “Trust the model” is the whole pitch
- A single-use code travels with the buyer to checkout
- Amazon's own order data confirms the redemption
- Spend joined to revenue every 15 minutes, per ad set
- Every row is auditable — code, order, cohort, timestamp
Talk like the board.
- Cohort
- One offer: a promotion flight tied to one ad set — its tracking ID, discount, code pool, flight window, and break-even CPA.
- Tracking ID
- A seller-defined promotion name that Amazon returns on every redeemed order. The join key between Meta spend and Amazon revenue.
- Code pool
- Pre-generated single-use Amazon claim codes, assigned to leads exactly once. Pool depth and burn rate live on the board.
- Flight
- The cohort's live window. Drives live, scheduled, and expired states — and the waitlist when codes run out.
- Break-even CPA
- The most a redemption may cost in ad spend before the offer loses money. The red/green line of the whole board.
- True CPA
- Spend ÷ redemptions. Actual Amazon orders, not leads.
- Net MER
- Net revenue — after discount, estimated fees, and Brand Referral Bonus — divided by spend.
- 72-hour rule
- No verdicts until a flight matures. Grey numbers, no judgment.
The board travels.
Every flight gets a white-label, read-only live share link — Meta spend → Amazon revenue, by cohort — that you can hand to a partner, a boss, or a buyer. Live data behind an unguessable URL, revocable any time.
First flights are live now. One early read: a gut-health brand's first Bridge flight coincided with its best sales-and-traffic week of the year on Amazon. We publish mechanics, not cherry-picked ROAS — on a walkthrough, the board speaks for itself.
The same loop points at retail: through a rebate-platform partner, Meta ads drive Target and Sam's Club purchases, with redemptions confirmed back to the ad account. If your revenue lives on someone else's shelf, Bridge is how your ads get credit for it.
Cross the bridge.
