Practical workflows: Examples of automation prompts
Below are three reusable prompts you can copy into your favorite LLM tools (ChatGPT, Claude, Cohere Command, etc.) to automate common SEO tasks.

You can run this prompt in batch for every URL on your site, turning a repetitive task into an automated process.
On-page optimization prompt
Integrating this prompt with an LLM sandbox like E2B or Vercel allows you to process hundreds of pages per minute, keeping costs low thanks to per-second pricing.
