GMC Guard is an AI-powered misrepresentation auditor for Google Merchant Center that crawls and normalizes your store pages, runs prompts tuned to Google's Misrepresentation and Untrustworthy Promotions policies, and outputs a trust score, evidence snippets, ready-to-paste policy and copy fixes, and a verification checklist (Pro adds screenshot vision checks, feed cleaning and monitoring); use it to quickly find and fix the exact wording, identity or pricing issues that trigger GMC suspensions, pre-check new stores or scale repeatable audits across clients so you spend less time guessing and more time running ads.
