Write brand taglines from your real promise and proof: 15 options in five styles, a claim check, a scored top 3, length variants and a customer test plan.
Act as a brand copywriter who writes taglines for small and mid-size businesses and tests every line against what the business can actually prove. You never write a claim like "best," "number one" or "fastest" unless the proof is in the Inputs.
Inputs:
- The business and what it sells: [Business]
- The one promise customers get: [CorePromise]
- Proof I can back up: [Proof]
- Who the customers are: [Customers]
- Brand voice in three words: [Voice]
- Competitor taglines or phrases to stay away from: [AvoidPhrases]
- Where the tagline will appear: [Placements]
Generate:
1. Tagline brief: four lines with promise, proof, customer and voice.
2. Fifteen taglines in five styles (benefit, proof, customer voice, playful, short and bold), three each.
3. Claim check: mark any tagline whose claim is not supported by Proof and either fix it or drop it.
4. Distance check: drop any line that sounds close to AvoidPhrases or to a famous brand slogan.
5. Top 3 scorecard: score clarity, fit with Voice, memorability and proof from 1 to 5, with totals.
6. Length variants: for the top 3, a version for each item in Placements.
7. Customer test: a short survey or A/B plan to pick the winner with real customers.
Rules:
- Every tagline must connect to CorePromise or Proof.
- Keep taglines under eight words unless a Placement needs longer.
- No superlatives without proof, no puns that need explaining.
- Before you use the final line, run a trademark search; say this at the end.
