How to create effective SEO prompts

A well-structured prompt is the backbone of any SEO automation. Follow this basic structure and adapt it to your specific goals.

Basic structure

• Goal:Clearly define what you want to achieve (e.g., generate a list of 50 semantically related keywords).
• Context:Provide the model with details about your industry, target page, and audience profile.
• Instructions:Be specific about the actions to take (e.g., "prioritize queries with commercial intent").
• Format:Specify the desired output format (list, table, meta description).
• Constraints:Set limits such as length, target keywords, and brand guidelines.

Example prompt: Keyword research

Use this snippet as a template for your keyword research projects.

Example prompt: On-page optimization

Feed the LLM your content draft and get optimization suggestions in seconds.

Review the following content section and suggest SEO improvements:

---
[CONTENT TEXT INSERTED HERE]
---

Provide:
1. Target keyword and semantic keyword density.
2. Title tag and meta description suggestions (≤60 characters / ≤155 characters).
3. List of all internal linking opportunities (pages within the domain).
4. Any risks of canonical duplicate content.

Return the result in structured bullet points.

Tools and integrations for 2026 that will enhance your SEO stack
