− > Spillmark measures true lift with holdout tests, not platform-reported credit, and shows you the real profit your Meta ads make on Amazon. Built by a brand owner, tested on his own brand.− ## Three numbers. Only one of them matters.− - What Meta claims: Meta counts sales from people who saw or clicked your ad. Many of them would have bought anyway.− - What Amazon Attribution credits: Amazon credits Meta for shoppers who clicked a tagged ad and then bought. It misses people who saw the ad and searched later.− - What you'd lose if you stopped: This is the number that decides your profit. Nobody tells you this number.− Meta and Amazon both use an attribution model: a rule for which ad gets credit for a sale. Credit isn't cause. Spillmark measures cause.− 1. Upload your reports, or connect: Start with the Amazon and Shopify reports you already download. Or connect Seller Central, Meta and Shopify with read-only access.− 2. See your profit by channel: Sales minus Amazon fees, product costs and ad spend. You see what each channel really earns, not just what it sells.− 3. Run a holdout test and get an answer: Spillmark plans a test that pauses Meta ads in a few regions for a few weeks. Then it compares Amazon sales there with everywhere else. You get the sales your ads caused, with a range that shows how sure the answer is.− - Lift, or incrementality: The sales that happen because of your ads. Not the sales your ads get credit for.− Pay monthly, cancel anytime, no sales call. Test plans are priced by your Meta spend.− - Dashboard, $19 a month: See where your profit really comes from.− - Starter, $49 a month: For brands spending up to $3k a month on Meta.− - Growth, $199 a month: For brands spending over $3k a month on Meta.− ## Questions− - Is my data safe? Spillmark asks for read-only access. We never store buyer names or addresses. Your data is never shared with other brands. Disconnect any time, and we delete your data within 30 days, or delete your brand from Settings and it's gone straight away.− - Am I too small? Maybe, and you'll know before you start. Spillmark checks your order history first and shows the smallest change a test could spot. If a test can't give a clear answer at your size, it tells you, so you don't pause ads for nothing.− - How long until I get an answer? You see profit by channel as soon as your reports are in. A holdout test runs 4 to 12 weeks. Spillmark tells you how long yours needs before it starts.− - Will it change my ads? Not on its own. Spillmark plans the test and shows you what to change. Nothing changes without your approval.− - What does it cost, and what do I get for $19? $19 a month gets you the dashboard, imports and profit by channel. Holdout tests start on Starter.− - Why price tests by Meta spend? The more you spend on Meta, the more it's worth knowing what those ads really do.− - Can I switch plans? Yes, anytime from Settings. Changes apply from the next billing month. If your Meta spend goes over your plan's limit, we'll tell you and suggest the right plan. Nothing stops working mid-test.− - [Geo testing (geo lift tests)](https://spillmark.com/learn/geo-testing): Measure ads by turning them off in some regions and comparing sales.− - [Ad measurement glossary](https://spillmark.com/learn/glossary): Plain-English definitions of the terms Amazon and Meta advertisers meet: ROAS, ACoS, TACoS, attribution, incrementality, holdout tests and more.+ > See profit after fees and ads on one Amazon dashboard.
