Scale The Ads Causing Sales. Cut the Ones That Don't.
Geo-based randomized controlled trials isolate true incremental lift across every channel and campaign - showing you which ads actually create new customers, and which are burning money by stealing the credit.
Attribution Misleads. Measure Incrementality.
Most advertisers still use click-based attribution. Single- or multi-touch, it credits whatever was clicked before a purchase - that's correlation, not causation.
The result: ads closest to the purchase get over-credited, while demand creation - often weeks earlier or on YouTube where clicks are weak - gets undercounted. Retargeting looks like a hero because it harvests demand created elsewhere.
As budgets and channels scale, the bias compounds: true customer creators get cut, CAC rises, and "winners" stall. Measure incrementality - the sales that wouldn't have happened without the ads - and invest in demand creation, not credit collection.
"Half the money I spend on advertising is wasted; the trouble is, I don't know which half."
Randomized Controlled Trials: The Gold Standard In Measurment
To scale without wasting budget, measure with randomized controlled trials (RCTs). Randomly assign comparable geo regions to treatment (ads on) and control (ads off), then compare outcomes. The difference is true causal lift (incrementality) - the same method used in clinical medicine, applied to advertising.
What incrementality unlocks: capabilities attribution can't deliver.
Prove Cause & Effect
Geo-based RCTs show incremental customers and revenue - what your ads cause, not just what gets clicked.
One Test, Cross-Platform Truth
Get a causal read across Meta, Google, TikTok, YouTube in a single experiment - one answer, no stitched reports.
Online + Offline Sales, Unified
Measure total lift across .com, Amazon, and retail so you see impact where money actually changes hands.
Move Budget With Confidence
Know which channels, campaigns, and creatives create incremental sales - back winners and cut waste fast.
Automated End-to-End
Simulates and selects the region split, pushes geo changes to each campaign, then cleanly reverts them when the experiment ends - no manual edits.
Privacy-Safe & Future-Proof
Geo-based RCTs don't rely on user-level data - privacy-safe and resilient to regulation or platform changes.
How to Optimize for Incrementality with Ad Causal
Design a Randomized Geo Trial
Pick the campaigns to test. We simulate region splits and use stratified sampling to assign comparable regions to treatment (ads on) and holdout (ads off). With Advanced Synthetic Controls, we build a near-identical counterfactual for each treatment region - isolating cause and effects of advertising.
Launch & Manage Automatically
We automatically deploy the new geo targeting region split to your campaigns, monitor contamination, ingest resulting sales data, then revert geo targeting cleanly once done - no manual edits. Weekly incrementality reports show a clear treatment-vs-control chart, daily lift and running incremental revenue.
Measure Incrementality
End-of-trial, you get a causal read: percentage incremental lift, total incremental KPIs (with upper and lower bounds), daily treatment effect, confidence score, and diagnostics for power, holdout integrity, and contamination. Use it to scale winners, cut waste, and plan next spend with projected lift.
