Creative A/B Testing
Pick the winner before you spend on Meta.
Most A/B tests burn budget on live traffic. Lewsearch lets you compare two concepts with directional synthetic respondents first, then a Quick A/B with a client-ready PDF in minutes.
Flash A/B runs on Pro. Every work-email signup gets 1 free study, enough for a full Quick Review or Quick A/B.
Two tiers
Flash for a directional read. Quick A/B for the client-ready report.
Flash A/B
Directional · n=50
- ✓50 respondents, each sees both versions (paired)
- ✓Paste copy or public URL, no upload
- ✓No study charge, with a daily limit. On Pro and above
- ✓Printable web page, no PDF
Quick A/B
~6 min · client-ready
- ✓500 respondents, each sees both versions (paired)
- ✓Image, PDF, DOCX, or URL upload
- ✓Counts as one study, A/B included, no surcharge
- ✓PDF emailed + interactive results
Sample deliverables
Real output from a DTC headline A/B test, not a mockup.
Same stimulus we used for smoke testing: two spring-sale headlines. Quick is the emailed client-ready PDF. Flash is on-screen only. A downloadable sample file is not posted on this site yet.
Quick A/B
Full synthesis memo with methodology notes and both stimuli shown. What you email before the client meeting.
Flash A/B
Flash is on-screen only. A sample is available on request.
When agencies use it
Before the pitch, before the media plan, before the client asks “why this one?”
The math
| Live ad A/B | Lewsearch | |
|---|---|---|
| When you learn | After spend | Before spend |
| Cost to compare 2 concepts | $500-$5,000+ ad spend | One study |
| Time | Days (impression threshold) | minutes, not a live send |
| Output | Conversion rate only | Sentiment, themes, quotes, winner |
Flash is directional qualitative feedback, not a replacement for live conversion data.
Two versions. One question. Answers in minutes.
Sign up, paste Version A and Version B, and run a Quick A/B. Flash is on Pro for now.
