Failure modes and when not to use

• Google policy traps: Phone numbers in ad text, bullet lists, generic CTAs like "click here", excessive punctuation or symbols, exclamation marks in headlines, mismatched landing-page claims.
• Meta policy traps: Text-heavy creatives (still hurts delivery), undisclosed AI-generated imagery, personal-attribute claims, restricted-category targeting mistakes.
• Always fact-check: The tool generates from your description. You are responsible for accuracy of claims. Ad platforms hold the advertiser liable, not the generator.
• High-stakes or restricted verticals: For finance, health, legal, political, or gambling ads, use generated copy only as a starting point and run full compliance review before upload.
• Brand voice and legal: If you have strict disclaimers, pricing rules, or tone requirements, add them manually after generation.
