Your Scraper Hit 187 Pages — Then Robots.txt Woke Up Mad
Scraped 300 electronics pages for a price tracker. Hit page 188, dead silence. Robots.txt changed overnight, serving 403s. Fun times.
⚡ Key Takeaways
- Refresh robots.txt every 5 minutes in long scrapers to catch mid-run blocks
- Small ecommerce sites dynamically ban via robots.txt on traffic spikes — proxies cost extra
- Ignore tutorials skipping periodic checks; they're setting you up for IP bans
