Test with sample products and activate --- 📖 Usage Guide Google Sheet Structure Your Google Sheet should have the following columns to ensure the workflow functions correctly: Product URL (Text): The direct URL to the Google Shopping product page. This is the primary identifier for the product. Product Name (Text): The name of the product. This will be automatically populated or updated by the workflow. Old Price (Number/Currency): The price of the product from the previous check. This column is crucial for price comparison. New Price (Number/Currency): The most recently scraped price of the product. Ratings (Number): The star rating of the product. Reviews (Number): The total number of reviews for the product. Timestamp (Datetime): The date and time when the price check was performed. Adding Products Add Google Shopping URLs to your Google Sheet. The workflow will fetch product details and track prices. Historical price data builds over time. Understanding Price Alerts The default setting for this workflow is to send an email alert when the new price equals the old price. This might seem counterintuitive, but it's useful for specific scenarios, such as: Monitoring stable pricing: If you are tracking a product and want to be notified when its price has remained consistent over time, indicating a potential stable buying opportunity or a benchmark. Verifying data consistency: To confirm that the scraping process is working correctly and consistently retrieving the same price when no changes are expected. You can easily customize the alert logic to trigger on different conditions as described below. Customizing Alert Logic Price drops: newprice < oldprice Significant drops: newprice < (oldprice 0.9) (e.g., price dropped by more than 10%) Price increases: newprice > oldprice Any change: newprice != oldprice Reading the Results Real-time pricing data Historical tracking Product metadata Timestamps for each check --- 🔧 Customization Options Add More Data: Descriptions, availability, seller info, shipping, images Modify Email Templates: Customize subject and body Multiple Recipients: Duplicate email node and change recipients Webhook Integration: Add real-time triggers or Slack alerts --- 🚨 Troubleshooting Bright Data connection failed: Check API credentials and dataset access No price data extracted: Verify URLs and test with different products Google Sheets permission denied: Re-authenticate and check sharing Emails not sending: Re-auth Gmail OAuth and verify recipients Filter not working: Check price formats and logic Workflow failed: Check logs, retry logic, and network status --- 📊 Use Cases & Examples E-commerce Monitoring: Track competitor pricing and trends Deal Hunting: Get alerts for price drops on wishlist items Inventory Management: Monitor supplier pricing for procurement Market Research: Analyze pricing trends and generate reports --- ⚙️ Advanced Configuration Batch Processing: Increase batch size, add delays, use parallel processing Price History: Store historical data, calculate averages, forecast trends Tool Integration: CRM, Slack, databases, BI tools (Tableau, Power BI) --- 📈 Performance & Limits Single URL: 2–5 seconds Concurrent Requests: 3–5 (depends on Bright Data plan) Data Accuracy: 95%+ Success Rate: 90%+ Daily Capacity: 100–500 products Memory: 100MB per execution API Calls: 1 Bright Data + 2 Google Sheets per product --- 🤝 Support & Community n8n Forum: < Documentation: < Bright Data Support: Via your Bright Data dashboard GitHub Issues: Report bugs and request features --- 🎯 Ready to Use!
