Ad copy variants

Ad copy for Meta, Google or LinkedIn in the right lengths, ready to A/B test.

Write ad copy for {{PLATFORM: Meta / Google Search / LinkedIn}} promoting {{OFFER}} to {{AUDIENCE}}.

Goal: {{GOAL: clicks, sign-ups, purchases}}.

Give 5 variants, each using a different angle (pain, outcome, social proof, urgency, curiosity). Respect the platform's limits:
- Google Search: 15 headlines (max 30 characters) and 4 descriptions (max 90).
- Meta: primary text (max 125 characters visible), headline (max 40), description (max 30).
- LinkedIn: intro text (max 150), headline (max 70).

No claims I cannot prove. Mark the variant you would test first.
