Proxies for Web Scraping
Web scraping uses proxies to distribute requests across many IP addresses so a target site never sees enough traffic from any single address to trigger a block. Instead of one IP making thousands of requests, a rotating pool spreads the load, mimics organic traffic, and keeps a scraper running. For public data collection, an anonymous or elite proxy that hides your origin IP is the practical minimum.
Why scrapers need proxies
Anti-bot systems fingerprint the source IP. Once a single address exceeds a request threshold, the site responds with CAPTCHAs, 429 Too Many Requests, or a hard block.
A proxy pool solves this by rotating the visible IP on each request or session, so the per-IP request rate stays under the radar while total throughput scales up.
Choosing the right proxy
Anonymity matters most: elite (high-anonymity) proxies send no headers that reveal a proxy is in use, while transparent proxies leak your real IP and are useless for scraping.
Latency matters second: a scraper is only as fast as its slowest proxy, so filter for sub-second response times before adding an IP to your rotation.
Protocol matters third: HTTPS and SOCKS5 proxies handle encrypted traffic and modern sites; SOCKS5 also supports UDP and authentication.
How to filter proxies in Proxcy
- Filter Anonymity to Elite to exclude proxies that leak your origin IP.
- Sort by Speed and keep only sub-500ms proxies for a responsive rotation.
- Filter Protocol to HTTPS or SOCKS5 for encrypted, modern-site compatibility.
- Pick a country close to the target server to minimize round-trip latency.
Frequently asked questions
What kind of proxy is best for web scraping?+
Elite (high-anonymity) HTTPS or SOCKS5 proxies are best, because they hide that a proxy is in use and encrypt traffic. Filter Proxcy to Elite anonymity and sub-second speed, then rotate across the pool.
How many proxies do I need to scrape a website?+
It depends on the site's rate limit. If a site blocks after 10 requests per minute per IP and you need 600 requests per minute, you need at least 60 rotating IPs to stay under the threshold.
Will rotating proxies stop me from being blocked?+
Rotating proxies dramatically reduce IP-based blocks, but sites also fingerprint browsers, cookies, and behavior. Pair proxies with realistic headers, request delays, and session handling for the best results.
