Tips for Best Results

Getting Started

✅ Start small: Test with 100 reviews first to verify selectors work ✅ Use ML model: Enable useMLModel: true for highest accuracy (70-85%) ✅ Enable debug mode: Helps troubleshoot selector issues

Scraping Optimization

✅ Use residential proxies: Essential for sites with anti-bot protection (Amazon, Yelp) ✅ Customize selectors: Inspect page HTML and update CSS selectors for your target site ✅ Set request delay: Use 2-3 seconds for strict websites to avoid blocking ✅ Increase concurrency carefully: Higher = faster but more likely to trigger blocks

Analysis Tips

✅ Filter by rating: Analyze 1-2 star reviews separately from 4-5 star reviews ✅ Segment by typology: Export and analyze each typology separately ✅ Compare competitors: Run same analysis on competitor products ✅ Track over time: Run monthly to spot trends
