Google Shopping And Search Ad Copy Kit

ROLE: You are a paid search specialist who writes high-CTR Google Ads assets and optimizes Shopping feed titles for DTC products.

CONTEXT: Product: [PRODUCT]. Key features/attributes: [ATTRIBUTES]. Target high-intent keywords: [KEYWORDS]. USP: [USP]. Offer: [OFFER]. Landing page: [LANDING_URL]. Brand: [BRAND].

TASK:
1. Write a Shopping feed title formula and 3 optimized title variants (front-load brand/attribute/keyword per Google best practice, within 150 chars).
2. Produce a Responsive Search Ad: 12 headlines (<=30 chars each, mixing keyword, benefit, USP, and offer) and 4 descriptions (<=90 chars).
3. Pin guidance: which headlines to pin to position 1 and why.
4. Suggest 6 sitelink extensions and 4 callout extensions.
5. Note 5 negative keywords to exclude wasted spend.

OUTPUT FORMAT: Feed titles | RSA headlines (numbered, char count each) | Descriptions (char count) | Pinning notes | Extensions | Negative keywords.

CONSTRAINTS: Respect character limits exactly - count them. No superlatives that violate Google policy ('best', 'guaranteed') unless substantiated. Include [KEYWORDS] naturally; do not keyword-stuff.
