Detect Competitor SEO Changes with Claude & WhatsApp Alerts

Detect competitor SEO changes fast—get WhatsApp alerts powered by Claude

This n8n workflow crawls your competitors on a schedule or via webhook, stores full site snapshots, diffs each run, and uses Anthropic Claude to explain the likely SEO strategy behind changes—sending WhatsApp alerts for significant shifts and a final digest.

What this workflow does

• Runs on schedule or on-demand: you can trigger it automatically, via a POST webhook to register a competitor, or manually for testing.
• Builds a competitor queue: it creates the crawl list from the webhook payload or by fetching your tracked competitors from your historical database API.
• Crawls competitor sites: it fetches HTML pages up to your configured page and depth limits, extracting titles, canonicals, H1s, JSON-LD schema types, internal link counts, word count, and a content hash.
• Diffs against the last snapshot: it retrieves the previous snapshot from the historical database API and computes changes such as new content clusters, deleted pages, URL migrations, title changes, schema changes, internal link changes, and content updates.
• Explains the strategy with Claude: the workflow sends detected changes to Anthropic Claude to generate a strategic narrative, confidence score, and recommended counter-actions. It then flags significant shifts based on change-volume and confidence thresholds.
• Notifies via WhatsApp: significant strategy changes trigger a WhatsApp alert. After processing all competitors (or reaching the run limit), it sends a WhatsApp digest and returns the digest via the webhook.

Use cases

• Track SEO volatility for key competitors and react immediately to migrations, schema changes, or large content updates.
• Maintain an always-on competitor intelligence workflow for SaaS operators and in-house SEO teams.
• Automate reporting in n8n with WhatsApp notifications instead of waiting for manual audits.

Technical details
