SERP Tracker n8n Workflow: Winners/Losers + Claude + WhatsApp

Know who’s winning (and losing) your rankings—then alert your team instantly

This SERP Tracker n8n workflow monitors daily Google SERP changes for your keywords by saving historical snapshots, detecting winners/losers, analyzing patterns with Anthropic Claude, and sending WhatsApp alerts when your tracked domain moves.

What this workflow does

The workflow tracks one or more keywords and highlights meaningful SEO movement:

• Triggers daily on a schedule, via manual run/testing, or immediately through a POST webhook that registers a {keyword, targetDomain}.
• Builds a processing queue either from the webhook keyword or by fetching all tracked keywords from your historical database endpoint.
• Pulls up to the top 100 organic results for each keyword from your SERP API, normalizing results into position, domain, URL, title with a timestamp.
• Diffs current vs. previous snapshots from the historical database to detect movers, new entrants, and dropouts—then saves the new snapshot back.
• Selects winners and losers and sends the movement data to Anthropic Claude to infer shared characteristics and notable SERP changes.
• Classifies the current SERP pattern using Claude, combining Claude’s SERP insights with the tracked domain’s movement and recommended next actions.
• Sends an immediate WhatsApp alert when the tracked domain’s movement is significant.
• Generates a run digest after processing all keywords (or hitting the per-run cap) and sends it via WhatsApp.

Use cases

• SEO/SaaS teams tracking keyword volatility for multiple clients or products.
• Automation engineers validating SERP impact for a specific target domain.
