Practical example: from keyword to optimized page
Here’s a ready-to-use prompt you can copy into ChatGPT, Claude, or any LLM with API compatibility. Replace[KEYWORDS]and[TARGET-AUDIENCE]with your own data.
Generate an SEO-friendly title, meta description, and introduction for the keyword "[KEYWORDS]".
Include the primary keyword in bold and keep the title to 60 characters and the meta description to 155 characters.
Write in a conversational style, addressing [TARGET-AUDIENCE], and suggest an H2 heading structure with secondary keywords.
Add a call to action at the end of the introduction.
Use schema.org Article markup for the title and meta description.Typical result (excerpt from a recent execution):

Best practices for creating effective prompts
Define the context
Start with a brief description of the page’s goal, target audience, and competitive landscape. The more context the LLM has, the more relevant the content will be.
Specify the format
Use explicit markup (e.g., "Use bullet lists," "Use a table for...") to ensure consistency in the output.
Include optimization constraints
Specify keyword density, content length, and schema usage. For example: "Keep the primary keyword density between 1% and 1.5%."
Iterate with feedback
Capture the SEO score the LLM assigns (e.g., using an integrated readability check). Use this feedback to refine the prompt in future iterations.
