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, Flash A/B in ~30 seconds, or Quick A/B with a client-ready PDF for $38.
Work-email signup includes 1 free credit, up to 4 Flash A/B runs (~$5 effective each) or one Quick Review (single).
Two tiers
Gut-check fast. Upgrade when the client needs a deck.

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, 50 respondents per tier. Flash is the printable web result (~30 sec). Quick is the emailed client-ready PDF.
Flash A/B · ~$5 effective
Sentiment, winner, themes, and respondent quotes from a DTC headline test. Printable web export (~30 sec run).
Quick A/B · $38
Full synthesis memo with methodology notes and both stimuli shown. What you email before the client meeting.
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 | $5–$38 |
| Time | Days (impression threshold) | from ~30 sec to 6 min |
| Output | Conversion rate only | Sentiment, themes, quotes, winner |
Flash is directional qualitative feedback, not a replacement for live conversion data. Use it to narrow concepts before media.
