Nano Banana Ad Variant Prompts: 15 Templates for Consistent Campaign Creatives

Jan 29, 2026

Nano Banana ad variant prompts (10 templates for consistent campaigns)

Back to hub

If you run ads, your problem is not "make one cool image." Your problem is "make usable variations that look on-brand."

These templates are designed for:

  • copy-safe negative space (you add text later)
  • consistent lighting and palette across a set
  • A/B tests where only one variable changes

The rule that makes ad variants work

Change one variable per variant. If you change subject, background, lighting, and style at once, you cannot learn what caused performance changes.

Ad prompt formula

Goal + Hero subject + Format + Layout + Brand palette + Constraints

Constraints you will reuse:

  • "no text, no letters, no watermark"
  • "leave [X]% empty space for copy"
  • "clean composition, minimal props"

10 copy-paste prompts for ad variants

1) 1:1 paid social set (4 variants)

Create 4 square (1:1) ad-ready variations featuring [PRODUCT] as the hero. Keep lighting and style identical. Change only the background: (A) clean white, (B) soft gradient in [BRAND COLORS], (C) subtle paper texture, (D) blurred lifestyle backdrop. Leave 30% copy-safe empty space. No text.

2) 4:5 feed format (product and copy space)

Vertical 4:5 ad image with [PRODUCT] as hero, premium commercial lighting, clean background, strong focal point, leave top third empty for headline overlay, no text, no watermark.

3) 9:16 story or reels hero (copy-safe)

Vertical 9:16 story ad background with [PRODUCT/SUBJECT], dynamic lighting, clean composition, leave center area empty for copy overlay, no text, no letters.

4) Before vs after (no words)

Create a split-screen image showing before vs after for [USE CASE]. Left side looks messy or problematic, right side looks clean or optimized. Modern commercial look, consistent lighting, no words, no text.

5) Minimal prop swap A/B test

Create 3 ad variations of [PRODUCT] with identical lighting and camera angle. Only change one prop: (A) [PROP A], (B) [PROP B], (C) [PROP C]. Clean background, copy-safe space, no text.

6) Colorway test (same scene)

Create 3 ad variations of the same scene with [PRODUCT], identical composition and lighting. Only change background color to (A) [COLOR A], (B) [COLOR B], (C) [COLOR C]. No text.
Create a consistent 5-image carousel visual set for [TOPIC]. Same palette [COLORS], same lighting, same style. Each image shows one concept visually (no words). Clean modern design, no text.

8) Landing hero background (abstract, copy-safe)

Website landing hero background for [INDUSTRY], abstract shapes and gradients in [BRAND COLORS], modern, friendly, lots of negative space for headline overlay, no text.

9) Seasonal ad set (tasteful)

Create 3 seasonal ad variations featuring [PRODUCT] with subtle [SEASONAL ELEMENTS], premium commercial lighting, clean composition, copy-safe space, no text.

10) Multi-format export pack

Generate the same ad creative for [PRODUCT] in 3 formats: 1:1, 4:5, 9:16. Keep style and lighting identical. Ensure copy-safe space in each. No text.

Troubleshooting (ads)

Problem: images are not copy-safe. Fix: explicitly reserve space.

Problem: variants do not look like a set. Fix: lock palette and lighting.

Problem: generator inserts text or fake logos. Fix: ban it.

FAQ

Q1: Should I generate ad copy inside the image? A: Usually no. Use "no text" and overlay copy later so you can iterate faster and localize.

Q2: What is the best way to A/B test? A: Change one variable per variant (background or prop or crop). Keep everything else fixed.

Q3: Which formats should I produce? A: Start with 1:1 plus 4:5 plus 9:16. That covers most paid social placements.

Q4: Next steps? A: More templates at /nano-banana-prompts. Generate now at /ai-image-generator.
