SEO Entity Gap Tracker: Claude + n8n + WhatsApp Alerts

Track SEO entity gaps automatically—and get WhatsApp alerts when competitors cover more

This SEO Entity Gap Tracker workflow uses Claude + n8n to extract named entities from your pages and competitor pages, then identifies missing or weakly covered entities. When gap counts cross your threshold, it sends WhatsApp alerts and a run digest.

What this workflow does

• Runs on a schedule, on-demand, or via webhook: execute weekly, manually, or when a POST webhook registers a topic with your URLs and competitor URLs.
• Builds a topic queue: uses the webhook payload or fetches all tracked topics from an external database endpoint.
• Crawls your pages and extracts entity signals: crawls provided URLs, extracts visible page text, then sends the combined content to Anthropic Claude to return a JSON list of relevant entities with prominence ratings.
• Crawls competitors (with delay) and compares: visits each competitor URL (with a short delay), extracts page text, and uses Claude again to get competitor entities + prominence.
• Computes gaps vs. competitors: aggregates competitor entities into a consensus table and determines which entities are missing from your pages or covered less prominently.
• Ranks recommendations and triggers alerts: Claude prioritizes entity gaps into ranked recommendations and thematic clusters, then sends a WhatsApp alert when gap count passes the defined threshold.
• Sends a digest at the end: after all topics (or a per-run topic limit), it sends a WhatsApp digest; for webhook-triggered runs, the digest is returned as the webhook response.

Use cases

• Detect why competitor pages outrank yours by finding named entity coverage gaps across topics.
• Operationalize SEO QA for SaaS content by getting WhatsApp alerts when issues exceed your threshold.
• Automate recurring SEO monitoring without manual audits—schedule weekly tracking or trigger via webhook.
