The essential points from this guide -- each one is explained in detail below.
Rotate IPs per request using a residential proxy pool.
Send realistic browser headers with every request.
Pace requests at human-like intervals (1-5 seconds between requests to the same domain).
Implement retry logic with exponential backoff for failed requests.
Monitor success rates per target and adjust strategy when they drop.
The most effective anti-ban measure is per-request IP rotation through a large residential proxy pool. Each request should come from a different IP address. With a pool of 90.4M+ IPs, no single IP accumulates enough requests to any one target to trigger rate limiting. Use a backconnect gateway that handles rotation automatically.
Anti-bot systems inspect your request headers for bot indicators. Every request should include a current User-Agent (rotate between recent Chrome, Firefox, and Safari user agents), Accept and Accept-Language headers matching the User-Agent, and consistent header ordering. Missing or inconsistent headers are the second most common cause of blocks after IP reputation.
Burst traffic (hundreds of requests per second to one domain) is trivially detectable. Add randomized delays between requests: 1-5 seconds for moderate pacing, 3-10 seconds for sensitive targets. Vary the delay randomly to avoid predictable patterns. Distribute concurrent requests across different target domains rather than hammering one domain.
When you encounter a block (403, 429, CAPTCHA), do not immediately retry with the same IP. Switch to a new IP, wait a random interval (exponential backoff: 2s, 4s, 8s, 16s), and retry. Track per-target success rates. If success drops below your threshold, pause scraping that target and adjust your strategy before resuming.
