Monitor competitor campaigns weekly using BrowserAct, OpenRouter, Google Sheets and Slack

Automate competitor campaign monitoring using BrowserAct & Openrouter

This workflow acts as an automated marketing analyst. It runs weekly to scrape competitor landing pages, compare them against historical data to detect changes in pricing, messaging, or offers, and delivers a strategic intelligence report to your Slack channel.

Target Audience Marketing managers, product strategists, and e-commerce owners who need to track competitor moves without manual checking.

How it works Scheduled Scan: The workflow triggers automatically every week. Retrieve Targets: It fetches a list of competitor URLs from a Google Sheet. Scrape & Compare: It loops through each URL. BrowserAct scrapes the live page content. An AI Agent (using OpenRouter/GPT-5) compares the live data with the previous week's data stored in the sheet. It detects price changes, new bundles, or messaging shifts. Update Database: The new data is saved to the Google Sheet for next week's comparison. Generate Report: A final AI Agent aggregates all the findings into a high-level summary, highlighting only significant changes (e.g., "High Severity" updates). Notify Team: The report is formatted for Slack and posted to your marketing channel.

How to set up Configure Credentials: Connect your BrowserAct, Google Sheets, Slack, and OpenRouter accounts in n8n. Prepare BrowserAct: Ensure the Competitor Campaign Monitoring (Huel) template is saved in your BrowserAct account. Setup Google Sheet: Create a Google Sheet with columns for Page URL and fields to store historical data (e.g., last_scrape_data). Configure Slack: Add your Slack Channel ID to the Send a message node. Activate: Turn on the workflow to start the weekly monitoring cycle.

How to customize the workflow Change Frequency: Adjust the Weekly Trigger to run daily or monthly depending on how fast your competitors move.

Add Email Alerts: Add a Gmail node to send the report to stakeholders who aren't on Slack.
