Geo Lift Testing Software
Looking for geo lift testing software that measures Meta ads on Amazon? Spillmark matches US states, plans the holdout, and reports lift with a range.
- States matched on your own ship-to history
- Pre-test check: can this design answer at your size?
- You approve before any region pauses
What you get
Spillmark runs geo holdout tests: ads pause in one group of states and stay on in the rest. It compares Amazon orders between groups and reports caused sales with a range.
Free holdout and brand-size calculators help you plan. Paid Starter ($49/mo) runs the live test on your data.
Sized before you spend the pause
Spillmark checks your order history and shows whether a geo holdout can answer at your size. If a test cannot give a clear answer, it tells you before you approve a pause.
When this fits
Use geo lift when you can target Meta by location and read Amazon sales by ship-to state. User-level platform lift studies are a different tool for outcomes those platforms can see.
Questions
- Do I pick the states myself?
- Spillmark plans matched groups from your history. You review and approve before anything pauses.
- What if my brand is small?
- The pre-test check and free brand-size calculator show the smallest lift a design can see. Do not pause for a test that cannot speak.
- Is open-source GeoLift enough?
- You can run GeoLift yourself. Spillmark adds planning on your orders, a locked ledger, profit context and an approval flow.
