Quick summary: 15 ready-to-use Gemini (Nano Banana) prompts built for Instagram Reels. For each prompt, you’ll get: the prompt text, a 3-second scroll-stopping hook, a caption example, a 3-beat storytelling format (hook/reveal / CTA), and tweak tips. Use these to create short-form videos that retain viewers and get shares.
Why Gemini (Nano Banana)? Google’s Nano Banana update made on-device image editing and stylized outputs far easier and faster, which creators are already using to create striking visuals and formats that perform on Reels. If you pair those visuals with tight hooks and clear CTA, you get the best chance to go viral.
How to use this post
- Copy the prompt into Gemini Nano Banana (or Gemini app).
- Generate the image or visual. Export vertical or 9:16 assets for Reels.
- Film short video clips that match the generated visual (or use the image as overlay/background).
- Use the 3-second hook as the first voice line or on-screen text. Keep the rest under 30–45 seconds.
- Use the suggested caption and CTA. Track retention and iterate. Best practices for hooks and structure are referenced below.
Hook & structure refresh (3 quick rules)
- Hook: First 3 seconds — provoke curiosity (question, shocking stat, “you won’t believe…”) or promise value. Short and direct wins.
- Retention: Use a 3-beat script: Hook → Value/Reveal → CTA (Save / Follow / Try). Keep edits fast, cuts on beats.
- Format: Reels that reveal transformation, show a step, or reveal a surprising fact tend to get extra replays (which signals the algorithm).

This simple structure follows proven short-form frameworks and helps improve retention.
Production checklist (so these actually perform)
- Vertical 9:16 assets: Always export Gemini outputs in 9:16 (or crop smartly) for Reels.
- First 3 seconds = promise: Use the hook as text + voice. No fluff.
- Add captions/subtitles: Auto-captions increase views and accessibility.
- Use trending audio: Pair visuals with trending sounds, trending audio = reach.
- Fast cuts: 1–3 second clips, keep pace after the hook.
- Pin CTA: Ask for saves or shares; “save this prompt” is a strong CTA.
- Test & iterate: Post A/B variations of hooks for 2–3 days; keep what sticks.
SEO & distribution tips (get found)
- Publish each prompt post with a clear H1 and include the full prompt in a
<pre>block (so Google understands it). - Include example outputs (images) with descriptive alt text like “Gemini Nano Banana portrait of [subject]”. This helps image search and discovery.
- Add short explainer paragraphs that teach how/why the prompt works — Google values original context.
- Share each pack to niche communities (r/MidJourney, r/PromptEngineering, creator Discords) and add linkbacks.
A/B testing plan (quick)
- Test hooks first — make 3 variations of the first 3 seconds. Track retention.

- Test thumbnails (first frame) — often determines CTR.
