Copy-paste prompt
Write a JSON spec for each of my [7] listing images, then generate them with Nano Banana Pro. For each image include: - "slot": main / secondary - "product_truth": what must stay exactly true (shape, color, size, label, what's in the box): [facts] - "amazon_rules": for the main image, pure white background, product only, no text or badges - "search_intent": the search query or buyer question from my Brand Analytics data this image answers: [queries] - "do_not_invent": features, claims, certifications or accessories that must not appear - "composition": layout, angle, props Generate from my raw photo following each spec exactly, and list anything you couldn't follow.
The source didn't publish its exact prompt. We wrote this starter so you can try the same workflow. Replace anything in [brackets].
What they did
An agency describes the system it built for one client whose listing had a CTR of about 0.6% and a CVR above 10%, so the problem was the click, not the page. They start from a raw phone photo and write a structured JSON spec for each image: what must stay true about the product, what Amazon allows in that image slot, the buyer or search intent from Brand Analytics the image should answer, and what can't be invented. Nano Banana Pro then generates main images, infographics, lifestyle shots and intent-driven visuals, and they measure CTR changes.
How it went
The post describes the system and the starting numbers (CTR about 0.6%, CVR above 10%). It gives no after numbers.
We only report what the source says. Results are self-reported unless noted.
Worth knowing
Agency post with no results yet. The useful idea is the JSON spec: it pins down product facts and Amazon's slot rules before the image model gets creative.
