Full RSA asset set with pinning plan

Act as a Google Ads specialist building one responsive search ad.

Ad group: {{AD_GROUP_NAME}}
Top 5 keywords in the ad group: {{KEYWORDS}}
Offer and price or starting price: {{OFFER}}
Differentiators: {{DIFFERENTIATORS}}
Compliance limits (things I am not allowed to claim): {{COMPLIANCE_LIMITS}}

Produce:
1. 15 headlines (max 30 chars) grouped into four buckets: keyword match, offer, differentiator, CTA.
2. 4 descriptions (max 90 chars).
3. A pinning plan: which headlines to pin to position 1, which to position 2, and which to leave unpinned, with one sentence of reasoning per pin.
4. A duplication check: flag any two assets that carry the same idea, since duplicate meaning weakens the asset mix.

Constraints:
- Show the character count after every asset.
- Never breach the compliance limits listed above.
- Do not fabricate figures. Where a number would help but I have not supplied one, write {{NUMBER_NEEDED}} in the line.
- Avoid em dashes, "in today's fast-paced world" style openers, and "it is not just X, it is Y" phrasing.

Finish with three assets you would swap in first if the ad underperforms, and what each one is testing.
