Google Ads Tests Nano Banana Pro AI for Creative Automation

Google Ads is intensifying testing on Nano Banana Pro (NB), its new AI-powered image generation and editing tool designed to streamline creative production across Performance Max, Display, and automated campaigns. The model introduces conversational image creation directly inside Google Ads, enabling advertisers to produce seasonal, mood-based, and material-specific visuals without the need for photoshoots or external design tools. Key Highlights Nano Banana Pro delivers fast, high-quality seasonal and material-based visual variations, making it a strong tool for ideation and asset-heavy campaigns like PMax and Display. Testing shows apparent limitations—brand restrictions, demographic bias, and unrealistic outputs—meaning NB is not yet suitable for regulated or brand-sensitive campaigns. Advertisers should treat NB as a creative accelerator, not a replacement for professional design, and continue using isolated testing and human review processes. Driving the news Ameet Khabra, founder of Hop Skip Media, conducted extensive real-world evaluations of Nano Banana Pro across three verticals—mattresses, HVAC, and real estate. Her tests aimed to understand how well NB performs under campaign-level conditions in which asset accuracy, brand consistency, and policy compliance directly affect performance outcomes. Khabra’s findings show the tool is powerful but imperfect, offering significant benefits for ideation while still requiring human oversight for brand-sensitive or regulated industries. The Good: Rapid Visual Variations With High Accuracy Testing revealed NB excels in scenarios where advertisers need quick creative diversification: Seasonal transformations rendered with accurate lighting, ambiance, and environmental cues. Material and finish edits—such as altering cabinet textures or furniture fabrics—preserved perspective and detail. Significant object additions behaved predictably, allowing reliable scene expansion for general marketing. Prompt refinement capabilities turned simple inputs into richer, more descriptive instructions. These strengths position NB as a valuable tool for campaigns that require continuous asset refreshes, such as PMax. The Bad: Brand Limitations and Visual Errors Still Persist Despite strong performance, Nano Banana Pro has limitations that advertisers need to manage carefully: Brand restrictions prevent the generation of logos, branded products, and detailed text overlays. Demographic bias and misplaced objects occasionally result in inaccurate or inappropriate visuals. Zoomed-out scenes and cross-image combinations can yield unrealistic or distorted results. These issues make NB unreliable for industries with strict identity, compliance, or representational requirements. The Weird: Literal Interpretations and Over-the-Top Choices NB also displayed unusual quirks during testing: Some prompts—like “luxury” or “masculine”—were interpreted too literally. Seasonal or holiday overlays occasionally became excessively aggressive. Mixed visual elements sometimes produced contradictory contexts. Bottom line for advertisers Nano Banana Pro is a promising creative accelerator—ideal for ideation, seasonal updates, and generating variations at scale. However, it is not yet a replacement for professional creatives in regulated or brand-sensitive environments. Testing in isolated asset groups, paired with human review, remains essential.
