Marketing Incrementality Tools
Looking for marketing incrementality tools aimed at Amazon brands on Meta? Spillmark runs geo holdout tests and reports caused sales with a range.
- Geo holdouts from your order history
- Design locked before the test starts
- Free calculators while you decide
What you get
Spillmark plans geo holdout tests for Meta ads across US states from your Amazon order history. It shows holdout share, length, smallest detectable effect and expected cost before you approve a pause.
Starter is $49/mo. Dashboard alone is $19/mo if you need profit first.
How results stay honest
The test design is locked with a hash before the test starts. Results go on an append-only ledger. When a result is too uncertain to call, Spillmark says so.
When this fits
Pick Spillmark when Meta → Amazon is the decision. Enterprise suites still fit multi-channel global brands with dedicated analysts.
Questions
- Is this the same as Meta conversion lift?
- No. Meta lift studies count outcomes Meta can see. Spillmark counts Amazon orders by ship-to state while Meta is paused in some states.
- Where is the method?
- See how lift is calculated on spillmark.com/how-lift-is-calculated.
- Free tools?
- Yes. spillmark.com/tools has holdout, brand-size and waste calculators.
