Meta → Amazon attribution
See every Amazon sale your Meta ads drive.
Amazon only credits shoppers who click a tagged link. Spillmark measures the ones who saw your ad and bought later, so you know your real Meta ROAS and where to put the next dollar.
Early access is opening to a small group of sellers first.
01
Connect Meta and Amazon
Link your Meta ad account, Seller Central, and Amazon Ads in a few clicks. Read-only access.
02
Tag every ad automatically
Spillmark adds Amazon Attribution tags to your Meta ads, so every click-through sale is credited to the right campaign and ad.
03
Measure the sales tags miss
Most shoppers see an ad, then search Amazon later. Geo holdout tests compare Amazon sales in regions with and without your ads to measure that lift.
Questions
- Doesn't Amazon Attribution already do this?
- It only credits shoppers who click a tagged link and buy. Anyone who sees your ad and searches Amazon later is invisible to it. Spillmark uses Amazon Attribution for the clicks and measures the rest.
- Who is it for?
- Amazon sellers and brands spending on Meta ads who want to know what that spend is really returning on Amazon.
- What will it cost?
- Plans will start at $20/month. Early-access members get founding pricing.
