Gemini Prompt for Writing Subtitles

Subtitles play a crucial role in structuring written content. Whether it's a blog post, a web page, a report, or a white paper, well-written subtitles guide the reader, improve readability, and enhance natural search engine optimization. Yet, finding the right wording—informative, engaging, and consistent with the text's tone—is an often underestimated exercise. Gemini, Google's artificial intelligence model, excels at contextual understanding and generating structured text. By providing a well-constructed prompt, you can obtain impactful subtitles that capture attention, hierarchize information, and perfectly adapt to your target audience. Whether you're writing marketing, educational, or journalistic content, Gemini helps you transform a raw outline into a professional title architecture. Discover below an optimized prompt and its variants to get the most out of Gemini for writing your subtitles.

The prompt

Gemini

You are an editorial writer expert in content structuring. I will provide you with the main topic of my text, its target audience, and the desired tone. Your mission is to generate a series of subtitles (H2 and H3) that structure the content logically and engagingly.

For each subtitle, respect these criteria:

Clarity: the reader should immediately understand the section's content
Engagement: use wording that makes them want to read on (questions, numbers, action verbs)
Consistency: maintain a uniform style across all subtitles
SEO: naturally integrate relevant keywords without over-optimization
Hierarchy: H2s cover the main parts, H3s detail the subsections

Main topic: [YOUR TOPIC]
Target audience: [YOUR AUDIENCE]
Desired tone: [professional / conversational / educational / persuasive]
Desired number of H2 sections: [NUMBER]
Main keywords to integrate: [KEYWORD 1, KEYWORD 2]

Generate the subtitles as a hierarchical outline with H2 and H3, adding a brief note (1 sentence) under each subtitle indicating the planned content for that section.

Why it works

This prompt works because it assigns a precise expert role to Gemini and defines explicit quality criteria (clarity, engagement, SEO, hierarchy), which frames the generation. The bracketed variables allow full customization while maintaining a rigorous structure. The request for descriptive notes under each subtitle forces the model to validate the logic of its own hierarchy, thus producing a more consistent result.

Expected result

You will obtain a complete hierarchical outline with logically organized H2 and H3 subtitles, each accompanied by a brief description of the section's content. The subtitles will be worded engagingly, naturally integrate your keywords, and maintain stylistic consistency throughout the document.

Variants by level

FAQ

How many subtitles can Gemini generate in a single request?

Gemini can easily generate between 10 and 30 hierarchical subtitles in a single request, covering multiple levels (H2, H3, H4). For very long content requiring more than 30 subtitles, it is recommended to break the request into broad thematic sections to maintain consistency and quality of each formulation. Always specify the desired number of sections in your prompt for a calibrated result.

How to ensure generated subtitles are SEO-optimized?

To maximize the SEO optimization of your subtitles, integrate your primary and secondary keywords directly into the prompt and explicitly ask Gemini to place them naturally. Also specify that you want formulations matching your audience's search intents (questions, comparisons, lists). Finally, ask Gemini to identify featured snippet or People Also Ask opportunities to position your subtitles for high-potential queries.

Can Gemini be used to rewrite existing underperforming subtitles?

Absolutely. Provide Gemini with your current subtitles, indicating the context (topic, audience, goal), and ask it to propose 2 to 3 variants for each subtitle. Specify what isn't working (too vague, not engaging, lack of keywords) so the model targets its rewrites. This approach is particularly effective for refreshing existing content with high bounce rates or stagnating SEO rankings.
