Nano Banana prompts for ads: 20+ templates that actually work

Most Nano Banana prompt guides give you "a cat wearing a hat" examples. Not useful if you're trying to ship ad creatives. This guide is different: every prompt below is built for product photography, lifestyle ads, UGC-style content, and social media creatives. Copy them, swap in your product details, and generate.

All prompts work with Nano Banana 2 (Gemini 3.1 Flash Image) and Nano Banana Pro. NB2 is faster and handles text rendering better, so it's the default recommendation for ad work.

How should you structure a Nano Banana prompt for ads?

The biggest mistake people make is writing vague one-liners. Nano Banana performs best when you prompt it like you're briefing a commercial photographer. That means specifying six things:

Element	What it controls	Example
Subject	The product or person	"a matte black wireless earbud case"
Composition	Camera angle and framing	"shot from a 45-degree angle, shallow depth of field"
Lighting	Mood and professionalism	"soft diffused studio lighting, single key light from left"
Setting	Where the scene happens	"on a marble countertop, minimalist kitchen background"
Style	The visual treatment	"editorial product photography, clean and modern"
Action	What's happening	"lid slightly open, one earbud floating above"

Skip any of these and the model fills in the gaps with generic choices. That's how you end up with stock-photo-looking output.

Nano Banana 2 also accepts image references alongside text prompts. Upload your actual product photo and use the @Image1 tag in your prompt to maintain product accuracy. This alone fixes most "doesn't look like my product" complaints.

Product photography prompts

These work for e-commerce listings, display ads, and hero images. Each prompt assumes you want clean, studio-quality output.

Hero product shot:

Editorial product photograph of [YOUR PRODUCT] on a [surface material] surface.
Shot with a 85mm lens at f/2.8, shallow depth of field. Single soft key light
from upper left, subtle fill light from right. Background is [color] gradient,
slightly out of focus. Product fills 60% of frame. No text, no props. 4K resolution.

Lifestyle context shot:

[YOUR PRODUCT] sitting on a [specific surface] in a [room type]. Morning light
coming through a window on the left side. A [contextual prop like coffee mug or
notebook] sits nearby but slightly out of focus. Shot on a 35mm lens, natural
color grading, warm tones. The scene feels lived-in, not staged.

Flat lay:

Top-down flat lay of [YOUR PRODUCT] centered on a [background color/texture].
Surrounded by [2-3 contextual items] arranged asymmetrically. Even, shadow-free
lighting. Negative space on [left/right] for text overlay. Shot at f/8 for
sharpness across entire frame. Clean, editorial style.

Multi-angle set (for carousels):

[YOUR PRODUCT] photographed from a [specific angle: front/side/back/three-quarter].
Pure white background, no shadows. Product centered in frame with 15% padding on
all sides. Studio flash lighting, even exposure. Color accurate, no filters.
E-commerce product listing style.

Run this prompt four times, changing the angle each time, and you get a full carousel set.

These create the kind of images you'd run on Instagram, Facebook, or TikTok feed ads. The goal is to look native to the platform, not like a studio shoot.

UGC-style "person using product":

A [age range, gender] [doing specific action] with [YOUR PRODUCT] in [specific
real-world location]. Shot on an iPhone, natural lighting, slightly warm color
grade. The person is [specific expression or body language]. Candid, not posed.
Slight grain. The [product] is visible but not the forced center of attention.
Aspect ratio 4:5.

Before/after split:

Split image, left side and right side. Left: [describe the "before" scenario
without the product, slightly muted colors, messier]. Right: [describe the
"after" scenario with the product, brighter, cleaner]. Same camera angle on
both sides. Dividing line down the center. Documentary photography style.

Testimonial-style background:

Blurred lifestyle background of a [specific environment like home office, gym,
kitchen]. Warm, natural lighting. Shallow depth of field, everything slightly
out of focus. Space in center-left for text overlay. Aspect ratio 1:1.
No people, no products. Soft, approachable color palette.

This gives you a background for overlaying customer quotes or review text in your ad editor.

Vertical video thumbnail style. [Person or product] in center
frame, [action happening]. Bright, saturated colors. Text-safe
zones at top and bottom (leave empty). Energetic, casual mood.
Shot from eye level. Aspect ratio 9:16.

[YOUR PRODUCT] in a lifestyle setting, [specific scene]. Warm
natural lighting. Product positioned in lower-right third.
Upper-left third has clean negative space for headline text.
Aspect ratio 4:5. Instagram feed aesthetic, slightly desaturated.

Close-up of [person's hands/face] interacting with [YOUR PRODUCT].
Shot vertically, filling the frame. Natural indoor lighting.
Slight motion blur on hands to suggest movement. Top and bottom
20% of frame slightly darker for text. 9:16 aspect ratio.

Wide shot of [YOUR PRODUCT] in [setting]. Clean composition with
product in right third. Left two-thirds has simple, uncluttered
background for headline and CTA overlay. Professional lighting,
brand colors [specify hex codes]. 16:9 aspect ratio, banner ad
composition.

Text-heavy ad prompts

Nano Banana 2 finally renders text reliably. Previous versions mangled anything beyond three words, but NB2's text rendering scored near the top of GenAI-Bench benchmarks. Here's how to use it.

Sale/promo graphic:

Bold promotional graphic on a [brand color] background. Large white text reading
"[YOUR HEADLINE - keep under 5 words]" centered in the upper third. [YOUR PRODUCT]
in lower half, shot from a slight angle. Small text "[SUBHEADLINE]" below the
product. Clean, modern sans-serif typography. Aspect ratio [specify].

Price card overlay:

Product card design. [YOUR PRODUCT] on a clean white background, occupying the
left 60% of the frame. Right side has a vertical [accent color] stripe with
white text: "[PRODUCT NAME]" in bold, "[PRICE]" in large font below, and
"[SHORT TAGLINE]" in smaller text. Minimal, Apple-style aesthetic. 1:1.

Even with NB2's improvements, keep text prompts to 6 words or fewer per text element. Longer phrases still produce occasional letter swaps. For headlines over 6 words, generate the image without text and add the copy in your editor.

Prompts for A/B testing variations

The real value of AI-generated ad creative is testing volume. One prompt structure, five variations, run them all and let the data decide.

Pick your base prompt

Choose any prompt from the sections above that matches your ad format. This becomes your control.

Create a variation matrix

Change one variable at a time. For a product shot, your matrix might be:

Variation A: Change background color (white to warm beige)
Variation B: Change lighting direction (left key light to overhead)
Variation C: Change setting (studio to kitchen counter)
Variation D: Change composition (centered to rule-of-thirds)

Generate at 512px first

Nano Banana 2 added a 512px resolution tier specifically for rapid iteration. Generate all variations at low-res to evaluate composition and mood. Pick winners, then regenerate at 2K or 4K.

Use conversational editing, not re-rolls

If a generation is 80% right, don't start over. Tell the model what to fix: "Move the product slightly left and make the lighting warmer." NB2 is better at targeted edits than cold re-generation.

At $0.067 per 1K image on NB2, running 50 variations costs about $3.35. That's less than a single stock photo license.

Common prompt mistakes (and how to fix them)

Too vague: "A nice photo of my product" gives you generic output every time. Fix it by specifying the lens, lighting, angle, and mood.

Too many instructions in one prompt: Don't ask for a lifestyle scene with text overlay, multiple products, and a specific background all at once. Break complex compositions into steps. Generate the scene first, then use NB2's editing capabilities to add elements.

Wrong aspect ratio: Nano Banana defaults to square if you don't specify. Always include "aspect ratio [X:Y]" at the end of your prompt. Get this wrong and you'll crop important elements later.

Forgetting brand consistency: If you're generating a set of ads for a campaign, include specific color hex codes and style descriptors in every prompt. "Brand color #2D5BFF as accent" is better than "blue accent." Without this, each generation picks a slightly different shade and your campaign looks inconsistent.

Fighting the model's strengths: Nano Banana excels at photorealistic output and product photography. Pushing it toward heavy illustration or graphic design styles produces weaker results. Use it for what it's good at.

How to go from Nano Banana images to finished ads

Generating the images is step one. You still need to composite them into actual ad creatives with copy, CTAs, brand elements, and correct export specs. That's where the workflow usually breaks down. You end up in Figma or Canva or Photoshop assembling the final pieces manually.

Cospark

Cospark connects image generation to the rest of the ad production workflow. Generate product shots with models like Nano Banana 2, then produce video ads, add voiceovers, overlay captions, and export finished creatives for every platform. One tool instead of five.

Frequently asked questions

What's the best Nano Banana model for ad creatives?

Nano Banana 2 (Gemini 3.1 Flash Image) is the better choice for most ad work. It generates at Flash speed (under 2 seconds typical), renders text more reliably, and reaches 4K resolution. Nano Banana Pro still edges ahead on some complex multi-step edits, but NB2 wins on speed-to-quality ratio for production workflows.

How many words can Nano Banana 2 render accurately?

Short text (1-5 words) renders accurately in most generations. Longer text (6-10 words) works but may need a regeneration or two. Beyond 10 words, generate the image without text and add copy in your ad editor. The improvement from the original Nano Banana to NB2 is significant, but it's still not a typography tool.

Can I use Nano Banana images in paid ads?

Yes. Google's terms allow commercial use of images generated through the Gemini API. Check the current terms of service for your specific access method (direct API, Google AI Studio, or third-party platforms), since usage rights can vary by integration.

How much does it cost to generate ad creatives with Nano Banana 2?

Google AI Studio offers a free tier with 500 requests per day. Beyond that, API pricing is $0.067 per 1K image, $0.101 per 2K, and $0.151 per 4K. For context, 100 ad variations at 1K resolution costs $6.70. Third-party providers like fal.ai may offer different rates.

Should I use the @Image tag for product shots?

Yes, always. Upload a real photo of your product and reference it with @Image1 in your prompt. This gives Nano Banana a visual anchor so the generated output actually looks like your product. Without it, the model invents product details and you get something that resembles your product category but not your actual item.
