Monthly On-Page SEO Audit n8n Workflow: Gmail + Telegram Reports

Catch SEO issues every month—automatically

This n8n workflow performs a monthly on-page SEO audit of your key site pages (plus sitemap.xml, robots.txt, and llms.txt), then delivers an HTML report via Gmail and a quick status summary via Telegram. No manual checking—just reliable alerts you can act on.

What this workflow does

• Runs on a schedule: a cron run at 7:00 AM on the first day of every month.
• Loads audit configuration (base URL, page paths, report email, telegramChatId, and optional tag-length limits) from the Set Audit Configurations step.
• Builds full URLs for each configured page plus sitemap.xml, robots.txt, and llms.txt.
• Fetches and records results using HTTP requests (captures HTTP status code and response body).
• Checks core on-page SEO elements and page health, including:
  • HTTP 200 requirement
  • Title, meta description
  • Canonical URL
  • Exactly one H1
  • JSON-LD and Open Graph title
  • Accidental noindex detection
• Generates an HTML table report, emails it through Gmail, and sends a short issue summary to Telegram.

Use cases

• SaaS operators who want consistent SEO monitoring for landing pages and product documentation.
• Automation engineers building monthly QA for technical SEO signals and tag correctness.
• Teams that need rapid visibility when sitemap.xml / robots.txt / llms.txt content or page metadata changes.
