Rate Limiting and Respectful Crawling
Learn how to throttle requests, honor crawl-delay, and avoid overloading servers so your scraping stays ethical and sustainable.
Why Rate Limiting Matters
Even when scraping is legally permitted, hammering a server with rapid requests can degrade the site for real users and get your IP banned.
Respectful crawling means pacing your requests so you gather data without harming the host.
The Cost of a Request
Every request consumes server CPU, bandwidth, and database load. A scraper firing hundreds of requests per second behaves like a denial-of-service attack, even unintentionally.
- Small sites have limited capacity.
- Bursts spike server load.
- Steady, slow traffic is far kinder.
