What's the best AI image size for Google Display Ads?

300x250 pixels (Medium Rectangle) converts best for most niches. For mobile-first campaigns, prioritize 320x50 or 300x50 sizes, they get 22% more impressions on handheld devices.

Can I use AI-generated faces in Google Ads?

Yes, but Google requires disclosed AI content starting July 2026. FluxNote's *Ethical AI Faces* model generates compliant images with built-in disclosure metadata.

How much does AI image creation cost for Google Ads?

With FluxNote's $20 Pro plan, you get 50 AI images/month (~$0.40/image). Traditional stock photos average $5-10 per asset, AI saves 90% on creative costs.

Why do my AI ads get lower CTR than stock photos?

80% of underperforming AI ads lack contextual prompts. Add specifics like *"35-year-old woman happily using [product] in modern kitchen"* not just *"person with product"*.

How to make AI images look less artificial?

In FluxNote, enable *Ultra Realism Mode* and set *Texture Detail* to 90%+. Add negative prompts like *"CGI, cartoonish, plastic look"* this improves perceived quality by 31%.
