Detect Google SERP Intent Drift with Claude & WhatsApp Alerts (n8n)

Detect Google SERP Intent Drift and get WhatsApp alerts with Claude + n8n

If your keyword rankings are changing, the reason is often a shift in Google’s SERP intent. This n8n workflow monitors Google SERP snapshots over time, uses Anthropic Claude to classify dominant intent, detects meaningful intent drift, and sends WhatsApp alerts when drift crosses your confidence threshold.

What this workflow does

• Runs daily for all tracked keywords (or starts immediately via a POST webhook when a keyword is submitted; a manual trigger is included for testing).
• Builds a per-run keyword queue from the incoming webhook keyword, or by fetching your tracked keyword list from your historical database API.
• Collects live SERPs using your SERP API, normalizes top results and SERP feature flags, and saves daily snapshots to the historical database.
• Creates intent signals over time by converting a window of historical snapshots into a content-composition profile (informational, commercial, UGC/forum, video, other) plus SERP features.
• Uses Claude for intent classification by sending the period-by-period composition timeline to Anthropic Claude to determine dominant intent and confidence.
• Detects meaningful intent drift using Claude again, based on composition/feature deltas, and generates a narrative with recommended actions.
• Sends WhatsApp alerts for keywords with drift above the configured confidence threshold and sufficient history, plus a run digest (also returned as the webhook response when applicable).

Use cases

• Catch when “best …” queries shift from informational to commercial intent and adjust landing pages.
• Monitor brand/product keywords where SERP features (e.g., video/UGC patterns) indicate changing user needs.
• Give SaaS teams early warning so SEO content updates match the current SERP intent.

Technical details

• Designed for n8n with nodes including: if, set, code, webhook, whats app, and sticky note.
• Integrates with a SERP API for top results + feature flags, a historical database API for keyword tracking/snapshots, and Anthropic Claude for intent + drift reasoning.
