What Is Proxy Rotation
Proxy rotation means automatically changing the IP address your requests come from, either on every request or after a set interval. It spreads your traffic across many IPs so no single address makes a suspicious number of requests, which is the single most effective way to keep a scraper or automation running.
Why rotation matters
Websites rate limit and block IPs that send too many requests too fast. If all your traffic comes from one IP, that IP quickly looks like a bot and gets throttled or banned. Rotation makes your activity look like many separate users instead of one.
How rotation works
- Rotating endpoint: your provider gives one proxy URL that returns a new IP on each request. Your code never changes.
- IP list rotation: you hold a list of proxies and pick a different one per request.
- Timed rotation: the IP changes on a schedule, for example every few minutes.
ShiftProxies rotating residential and mobile endpoints give you a fresh IP per request from one URL, so you get rotation without managing a list at dashboard.shiftproxies.com.
When to rotate and when not to
- Rotate for large crawls and independent page fetches where each request stands alone.
- Do not rotate in the middle of a logged in session or a checkout. Use a sticky session there, because changing IP mid session is itself a red flag.
Rotation is not enough on its own
Rotation solves the volume problem, but you also need realistic headers, randomized timing, and high trust residential or mobile IPs on protected sites. A clean rotation with an obvious bot fingerprint still gets caught.
Summary
Proxy rotation distributes requests across many IPs so none of them looks like a bot. Rotate for discovery and bulk crawling, stay sticky for stateful flows, and pair rotation with good headers and pacing.
