1. Can ChatGPT write Facebook ads that comply with Meta's advertising policies?
ChatGPT can write ad copy, but it cannot guarantee policy compliance for every ad category. Meta's advertising policies restrict certain claims in categories including health, finance, housing, employment, and political ads. Always review AI-generated ad copy against Meta's current advertising policies before publishing, particularly for claims about outcomes, results, or benefits. The responsibility for compliance rests with the advertiser, not the AI tool.
2. How much should I budget to test a new Facebook ad campaign?
A useful starting rule is to budget at least 5-10x your target cost per acquisition (CPA) per ad set per week to give the algorithm enough data to optimize. For example, if your target CPA is £50, budget at least £250-500 per ad set per week. Testing without sufficient budget produces unlearnable results — you cannot tell whether an ad failed or simply did not have enough impressions to be fairly evaluated.
3. Which AI model is best for Facebook ad copy?
Claude tends to produce the most psychologically nuanced and emotionally resonant ad copy — particularly for hooks that tap into specific audience emotions and desires. GPT is strong for structured campaign strategy and A/B test planning. Grok can produce more direct and culturally current copy styles that work well for certain audiences. Chat Smith lets you access all three in one place so you can test different copy styles across models and find the approach that converts best for your specific audience.
