How to write ad copy that converts
Write variants by angle, not by synonym
Five headlines that say the same thing in different words teach you nothing. Test different reasons to click: pain, outcome, proof, offer and audience.
Respect the limits before you're in the ad editor
Google headlines truncate at 30 characters, and Meta primary text gets cut after a line or two on mobile. Write to fit, instead of trimming the best line later.
Match the landing page
The ad's promise should be the first thing people see after they click. A mismatch hurts conversion and, on Google, quality score.
Specific beats clever
“Taxes done in one click” outperforms wordplay nobody gets in the second they spend scrolling past.
Call out the audience
“For freelancers” in a headline filters out the wrong clicks before you pay for them.
Only claim what's true
“#1”, “best” and “guaranteed” can get ads rejected. Use proof you can back up.
The snippet
This is the exact prompt the tool above runs. Save it as a snippet in Snippetbar and it works on any text you select.
You are a performance marketer. Write ad copy for {platform: Google Search | Meta | LinkedIn} from the input below.
Rules:
- Use only facts from the input. No invented stats, awards, discounts, or superlatives ("#1", "best", "guaranteed").
- Write 4 variants, each testing a different angle: Pain, Outcome, Proof/Specific, Offer (or Audience if no offer).
- Respect limits: Google headline ≤30 chars, description ≤90. Meta primary text ≤125 chars, headline ≤40. LinkedIn intro ≤150 chars, headline ≤70.
- Plain, concrete language. No exclamation marks, no emoji unless the input uses them.
