Website SEO Audit n8n Workflow: Multi-Agent Claude Crawler

Get an instant, page-by-page SEO diagnosis—powered by six Claude agents in an n8n workflow.

This Website SEO Audit n8n Workflow: Multi-Agent Claude Crawler crawls your site from a start URL, extracts key on-page SEO signals from every page, and uses six Anthropic Claude analyses to score issues and return a complete JSON SEO audit report with site-wide averages and worst-page findings.

What this workflow does

• Receives crawl input via an n8n webhook (POST) (or can be run manually), including a start URL and crawl limits.
• Crawls with a queue: loops through discovered internal URLs until the queue is empty or the maximum page limit is reached, with a configurable request delay.
• Parses on-page SEO signals for each page by fetching HTML and extracting: title, meta description, canonical, robots meta, headings, JSON-LD presence, word count, image alt coverage, plus internal/external links.
• Scores and detects issues with six Claude agents, covering technical factors, intent, entity/topic alignment, internal linking, content quality, and architecture—then merges results into a single page diagnosis with an overall score and severity-sorted issues.
• Returns a final site report as JSON, including page-level diagnoses, site-wide averages, recurring issues, and the worst-performing pages.

Use cases

• Run an SEO audit workflow before launching a migration or redesign.
• Continuously validate key on-page SEO signals across an expanding content catalog.
• Spot systematic problems (e.g., missing canonical tags, weak metadata, or thin content) and prioritize fixes using severity rankings.

Technical details

• n8n webhook (POST) to start the crawl and return JSON results.
• Uses nodes: if, set, code, wait, merge, and webhook.
• Six Anthropic Claude agents analyze each page’s extracted SEO signals and produce JSON responses that are combined into the final report.
