n8n Brand Mention Monitor: Groq Sentiment + Slack Alerts

Spot brand mentions in real time—then get instant Slack alerts with Groq sentiment + suggested replies

This n8n automation workflow monitors Google News (and optionally Reddit/Trustpilot) for brand mentions every 15 minutes. It deduplicates near-identical stories, uses Groq to classify sentiment, intent, and severity, and posts high-severity Slack alerts with a draft reply—while logging everything to Google Sheets.

What this workflow does

• Runs on a schedule: executes every 15 minutes.
• Fetches mentions: pulls recent brand mentions from a Google News RSS search feed (with optional Reddit and Trustpilot HTTP sources that are disabled by default).
• Normalizes + deduplicates: converts each mention into a consistent schema and removes near-duplicate stories using title similarity.
• Classifies with Groq: sends each mention to the Groq Chat Completions API to determine sentiment, intent, severity, and a short reasoning.
• Alerts on what matters: when severity is high, Groq drafts a short public reply and the workflow posts an alert to a Slack channel including the classification, link, and suggested reply.
• Logs outcomes: appends all processed mentions (including non-high severity) to a Google Sheets spreadsheet.
• Reports errors to Slack: if a request or Groq call fails, it formats the error and posts it to a separate Slack error-reporting channel.

Use cases

• Track SaaS or e-commerce brand reputation by monitoring news coverage and customer discussion.
• Catch negative or urgent mentions early and respond faster with an AI-suggested draft.
• Centralize mention monitoring for automation engineers—complete with logging and Slack-based incident visibility.
