Website On-Page SEO Audit
Paste a URL and get a deep technical SEO audit with 10 specific recommendations emailed to you.
What it does
Paste any website URL to instantly receive an email with ten specific technical SEO recommendations designed to boost your search rankings. The system analyzes the site's code using AI to identify key issues and delivers a clear action plan directly to your inbox.
Step by step
- Parse the HTML response from the HTTP request tool to extract meta tags, headings, and image alt attributes.
- Construct a structured JSON prompt payload containing the scraped content and specific SEO criteria for the LLM.
- Format the final audit report as a clean HTML or PDF document before passing it to the email sending function.
Where the LLM does the work
- Analyze the provided HTML structure to identify technical issues like missing meta descriptions or broken internal links.
- Evaluate content quality and keyword density to generate ten specific, actionable recommendations for ranking improvement.
- Draft a professional and personalized summary of the findings tailored to the website owner's likely goals.
Watch out for
The scraped HTML might be dynamically rendered by JavaScript so you need to use a headless browser or API that supports JS execution to get full content.
Email providers often flag automated messages as spam so ensure you authenticate your Gmail account with SPF and DKIM records.
Large HTML payloads can exceed token limits so implement a strategy to truncate or summarize the source before sending it to the model.

Frequently asked questions
Can I use a different LLM than OpenAI?
Yes. OpenAI is only the example LLM in this recipe. The same flow works with Anthropic, Cohere, DeepSeek and Google Gemini. Swap the LLM connection and keep the rest of the setup as written.
Want this running in your business?
This is what I do. I design and build AI agents like this one, and keep them running. If you want it set up for your team instead of doing it yourself, get in touch.
Who it's for
