Python Web Scraping: How to Avoid Getting Blocked in 2026

Jun 14, 2026 • 6 min read

Websites are getting better at detecting bots. Here's what actually works in 2026 to avoid getting blocked.

1. Rotate User-Agents

Use a pool of real browser User-Agent strings and rotate them between requests. Chrome, Firefox, Safari — mimic real visitors.

2. Add Random Delays

Don't request pages at machine speed. Add random pauses between requests (1-5 seconds). Human browsing is irregular.

3. Spoof Headers

Send realistic Accept-Language, Referer, and Sec-Fetch headers. Most bots don't bother with these, making them easy to detect.

4. Use Rotating Proxies

For large-scale scraping, rotate IP addresses via proxies. Services like BrightData or ScraperAPI handle this for you.

5. Handle JavaScript Properly

Modern websites rely on JavaScript. Use Playwright (not just requests) for sites that load content dynamically.

6. Respect robots.txt

Check the target's robots.txt file. Ignoring it can get your IP banned and may have legal implications.

7. Monitor Response Patterns

If you suddenly get CAPTCHAs, different HTML, or 403 errors, stop immediately — you're being detected.
