How to Choose the Best Proxies for Web Scraping
The best proxies for web scraping are rotating residential proxies for protected sites and datacenter proxies for high-volume scraping of sites that don't aggressively block. The right setup distributes your requests across many IPs, targets the correct location, and paces requests so you avoid rate limits, CAPTCHAs and bans.
Which proxy type should you use?
- Protected sites (e-commerce, search, social, travel): rotating residential proxies for the highest success rates.
- High-volume, lightly protected sites: datacenter proxies for the lowest cost and fastest speed.
- Persistent sessions or logins: ISP proxies for a stable, trusted IP.
How proxy rotation works
Rotation assigns a fresh IP automatically — either on every request or after a set interval — so no single IP sends enough traffic to trip a rate limit. For workflows that need session continuity (multi-step forms, logins), use sticky sessions to keep the same IP for a defined time window.
Geo-targeting for accurate data
Prices, search results and content vary by location. Target by country, city or ASN to collect data exactly as a local user would see it. This is essential for price monitoring, local SEO and market research.
Practical tips to avoid bans
- 1Rotate IPs and spread requests across a large pool.
- 2Add realistic delays (1–5 seconds) and randomise them.
- 3Send realistic headers and rotate user agents.
- 4Respect robots.txt and reasonable request volumes.
- 5Use sticky sessions only where continuity is required.
- 6Monitor response codes and retry with backoff.
Proxies remove the IP bottleneck, but clean headers, pacing and good crawl logic are what keep success rates high on the toughest sites.
Frequently asked questions
What proxies are best for web scraping?
Rotating residential proxies are best for sites with strong anti-bot protection, while datacenter proxies are best for high-volume scraping of sites that don't block aggressively.
How many proxies do I need for scraping?
It depends on request volume and the site's rate limits. With rotating residential proxies you scale bandwidth rather than counting IPs, because the pool rotates automatically across millions of addresses.
How do I avoid getting blocked while scraping?
Rotate clean IPs, pace and randomise requests, send realistic headers, target the right location, and back off on errors. Residential proxies plus good crawl hygiene keep block rates low.
