Message and ad copy testing

Message and ad-copy testing
before you buy the media

Klingbar runs synthetic focus groups against a library of 185 personas tuned to the same audience parameters you use on Meta, Google, and LinkedIn. Put a tagline or an ad in front of the room, read what landed and what missed, and capture the exact words your buyers use — before a single dollar goes to media.

Live session · 10 personas

Maya, 32 Resonant
"Onboard in an afternoon" is the line that would stop my scroll. Every other tool promises weeks, so a half-day setup is the thing I'd screenshot.
Daniel, 41 Dissent
"An afternoon" reads like marketing to me. I'd believe "by Friday" before I'd believe a half-day claim with no caveats.
Lia, 24
I don't onboard tools, my team does. The promise is right; the word "onboard" makes me feel like I'm not the one being spoken to.

A vague time claim reads as marketing, not proof.
Run · variant by variant

Test every line against the audience you'll buy

Drop a headline, a subject line, an ad, or a landing-page hero in front of the room and run the session. Each persona reacts in their own voice — what they'd forward, what they'd scroll past, where the claim feels like proof and where it reads as marketing. Then probe the pushback: ask the follow-up, surface the real objection, and watch where the room agrees and where it splits on dissent.

Because the panel is synthetic, you can run the same message against a tighter segment, or run three variants back to back, in the time a single survey would take to field. Compose the room from the same filters your media team already targets, so a winning line is validated against the people you'll actually reach. Browse the full persona library to see who you can put in the room.

Synthesis · their words

The exact words they used, not a paraphrase

The synthesis names a resonance score, the objections that came up, and the language patterns the room reached for on their own. Those phrases are the payload: copy that uses your buyers' words clears the ad auction cheaper and converts warmer than copy written in your own voice.

Lift the winning phrases straight into the next ad, the landing-page hero, the subject line. Run the revised message back through the same room to confirm the lift held. It's the same loop behind concept testing — only here the unit under test is the language itself.

De-risk the spend

Test the message before the media budget

Most ad spend is a bet on a message that nobody outside the building has read yet. You write three headlines, pick one on a hunch, and let the auction tell you weeks later — in spend — which one your buyers ignored. A losing line doesn't just underperform; it burns budget teaching you something a room could have told you on day one.

A synthetic focus group moves that read forward. Run the variants, see which claim earns resonance and which draws dissent, and capture the language your buyers use to describe the value — all before the first impression is bought. Then take the validated line live with the model details behind the panel documented in our write-up on AI focus groups, and the full three-step loop laid out in how it works. You still buy the media; you just stop paying it to do your message testing for you.
