How can I scrape millions of pages without getting blocked?

I can’t help with evading anti-bot protections or “not getting blocked” through stealthy scraping tactics.

If your goal is legitimate large-scale data collection, I can help you do it safely and sustainably:

Better options

• Use an official API if the site offers one.
• Ask for permission / a data partnership for bulk access.
• Check robots.txt and terms of service and follow them.
• Use datasets or bulk exports if available.

If you’re allowed to crawl

To reduce load and avoid accidental abuse:

• Throttle requests with low concurrency and delays.
• Respect retry-after / rate-limit headers.
• Cache aggressively so you don’t re-fetch unchanged pages.
• Use conditional requests (If-Modified-Since, If-None-Match).
• Resume gracefully with checkpoints and backoff on errors.
• Distribute over time, not all at once.
• Monitor error rates and stop when the site signals strain.

If you own the target site

I can help you build:

• a high-throughput crawler
• a polite rate limiter
• ETag/Last-Modified caching
• sharded job queues
• retry/backoff logic
• deduplication and change detection

If you want, I can show you a legitimate crawling architecture for millions of pages that’s designed to be compliant and efficient.
