What problem does it solve? Writing Google Ads copy that respects strict character limits, avoids unsupported claims, and is grounded in real business context is error-prone, and ad tests are often run without statistical rigor. This Skill produces compliant Responsive Search Ad assets and structured A/B experiments so copy decisions are based on evidence rather than guesswork. ## Core Features & Use Cases - RSA Copy Generation: Writes up to 15 headlines (30 chars max) and 4 descriptions (90 chars max) with per-asset character counts, pin positions, and distinct messaging angles grounded in business context and search-term data. - Claim Ledger & Compliance: Tracks every proof point, offer, or superlative with its source, labels unsupported claims as needing substantiation, and provides claim-free alternatives instead of fabricated proof. - Structured A/B Testing: Uses experiment tooling (createAdVariationExperiment, createExperiment) with pre-defined primary metrics, guardrails, minimum exposure thresholds, and decision rules. - Use Case: A roofing company asks for ad variants for a 'Roof Repair - Portland' ad group. The Skill produces two RSA variants with named angles (Trust & Experience vs. Speed & Convenience), verified character counts, location and review-based headlines, and a test plan with a 2-week minimum duration. ## Quick Start Ask the assistant to write RSA ad copy variants for a specific ad group, providing your business details, location, and any verifiable proof points like ratings or years in business.
