Message testing with AI panels
AI panels can rank messages and list objections before you buy media. The decision-grade signal is directional: which line leads, which is confusing, who objects. On a Texas grocery brand block, Lewsearch's calibrated MAE was 4.14 percentage points and the top three brands stayed in order. That is not a click-through experiment.
What the panel can and cannot do
It can tell you which of two subject lines is clearer to Texas adults, and it can quote the objection. It cannot tell you your Meta CPA. Live tests still own conversion. The published panel error underneath the screen is 7.47% MAE on 404 public-poll items. Coverage: coverage (27 live panels · U.S. national · 4 census regions (32 audiences)). See methodology and message testing.
Worked example: rank order before spend
The Texas grocery brand block used six options, including don't-know, on 1,000 Texas shoppers. 4.14 points of MAE with a preserved top three is enough to kill a fourth-place line that an internal Slack poll had inflated. It is not enough to forecast a 2-point share shift after a $200,000 flight. If the two remaining lines are within a few points, take both to a cheap live split. Use the panel to avoid testing the line that confused people.
| Method | What it measures | When to use it |
|---|---|---|
| AI panel (Lewsearch) | Comprehension, preference, objections | Before you buy the test budget |
| Live A/B | Clicks, conversion, revenue | After the confusing variant is gone |
| Human focus group | Talk-aloud reaction | $4,000 to $12,000, weeks |
| Synthetic interviews | Themes and quotes | Discovery; Synthetic Users publishes $2–$60 / interview |
FAQ
- Can I test messages with an AI panel?
- Yes. Upload copy or creative, ask which is clearer or more credible, and read sentiment, objections, and option shares. It is a screen, not a conversion experiment.
- How accurate is that screen?
- On a UT/TPP Texas grocery brand-preference block, calibrated MAE was 4.14 percentage points and the top three brands were in the correct order. Brand as a category on the Texas panel is small-n. Treat rank order as the decision-grade signal.
- Is this an A/B test?
- It is a pre-spend read. Live A/B tests still measure clicks and conversion. Use the panel to drop the confused variant before you buy the impressions.
- Where do I run one?
- lewsearch.com/message-testing or /ab. Pricing is on /pricing. Method is on /methodology. Coverage is on /coverage.
