Ad Copy Generator + A/B Tester

Write Google Ads RSA copy and run structured tests to find winning messaging.

Setup

Read and follow ../shared/preamble.md (MCP detection, account selection) and ../shared/analysis-principles.md (evidence requirement, guardrails). Both apply throughout.

Reference

Read on demand:

• references/rsa-best-practices.md — character limits, headline formulas, pinning, A/B mechanics, common mistakes. The source of truth for what to write.
• references/rsa-testing-lab.md — how to choose RSA test metrics, diagnose ad-group intent bloat, decide pinning, and avoid chasing Ad Strength over business outcomes.
• ../manage/references/industry-benchmarks.md — industry CTR/CVR benchmarks for sanity-checking targets.
• ../manage/references/quality-score-framework.md — only when QS improvement is the explicit goal.

Business context — non-negotiable input
