How to Scrape Websites Without Getting Blocked in 2026

Getting your IP banned mid-scrape? Learn the proven techniques professionals use to collect data at scale — without triggering anti-bot systems.

Why Do Websites Block You?

Every time your scraper sends a request, the target server sees your IP address, your request headers, and your timing patterns. Anti-bot systems look for signals that reveal automated behavior:

  • Too many requests from a single IP — humans don't make 500 requests per minute.
  • No variation in headers — a real browser randomizes User-Agent, Accept-Language, and more.
  • Perfectly regular timing — bots hit endpoints at machine-clock intervals; humans don't.
  • Datacenter IP ranges — most hosting IPs are flagged the moment they appear in WHOIS.

Once you trigger one of these signals, you face a CAPTCHA, a soft block, or a permanent IP ban. The fix isn't to scrape more cleverly with a single IP — it's to stop looking like a bot in the first place.

Use High-Quality Proxies

The single most effective measure is routing your requests through proxies that look like real users. Not all proxies are equal, though. Here's how to choose the right type for your use case.

Rotating Residential Proxies

Residential proxies are IP addresses assigned to real households by ISPs. Websites see a genuine consumer connection, making them nearly impossible to distinguish from organic traffic.

Our Rotating Residential Proxies automatically cycle through a large pool of addresses on every request (or on a custom interval). You get:

  • IPs from real devices in 150+ countries
  • Automatic rotation — no manual pool management
  • High success rates on heavily protected targets like e-commerce and social media

Check out our Rotating Residential Proxies — the go-to choice for large-scale scraping.

IPv4 Proxies

Dedicated IPv4 Proxies give you exclusive use of a static IP address. They're ideal when:

  • You need a consistent identity (account management, ad verification)
  • Speed is the top priority — no sharing means no traffic spikes from other users
  • You're scraping targets that are not residential-sensitive

Because you're the sole user, trust scores build up over time on the same IP.

ISP Proxies

ISP Proxies sit in a sweet spot: they are hosted in datacenters for speed but are registered under real ISP blocks, so they pass residential checks.

Use ISP proxies when:

  • You need datacenter-level throughput and residential-level trust
  • Targets check ASN or WHOIS ownership (many do)
  • You want lower latency than a residential pool

Our ISP Proxies combine datacenter speed with ISP-level credibility.

IPv6 Proxies

The IPv6 address space is enormous — meaning each IPv6 proxy comes from an effectively unique block that anti-bot systems have little history on. IPv6 Proxies are a cost-effective option for targets that support IPv6, offering:

  • Ultra-low cost per IP
  • Massive address diversity
  • High throughput for simple, low-friction targets

Rotate IP Addresses

Even with a large proxy pool, how you rotate matters.

StrategyWhen to use
Rotate per requestMaximum anonymity; best for high-volume scraping
Rotate per sessionKeep a consistent identity across a login flow
Rotate on banDetect 403/429 responses and swap IPs automatically

Our residential proxy endpoints support sticky sessions (same IP for a configurable window) and pure rotation — you pick the mode in your request header, no extra code required.

import requests

proxies = {
    "http":  "http://user-rotate:[email protected]:10000",
    "https": "http://user-rotate:[email protected]:10000",
}

response = requests.get("https://example.com", proxies=proxies)
print(response.status_code)

For session-based scraping (e.g., logging in before scraping), swap rotate for a sticky session token so the same IP is used throughout the flow.

Add Random Delays

Even with different IPs, machine-perfect timing is a red flag. Add human-like pauses between requests:

import time
import random

def human_delay(min_s=1.5, max_s=4.0):
    time.sleep(random.uniform(min_s, max_s))

for url in urls_to_scrape:
    response = requests.get(url, proxies=proxies)
    process(response)
    human_delay()

Guidelines:

  • 1–4 seconds between page requests on most sites
  • 5–15 seconds between bulk actions (form submissions, logins)
  • Introduce occasional longer pauses (20–60 seconds) every N requests to mimic reading time

Combining random delays with IP rotation makes your traffic pattern statistically indistinguishable from real user behavior.

Additional Techniques That Help

Randomize Headers

Set a realistic User-Agent string and rotate it. Also include Accept-Language, Accept-Encoding, and Referer headers to match a real browser fingerprint.

Use a Headless Browser for JS-Heavy Sites

Sites that render content client-side require Playwright or Puppeteer. Pair these with our residential proxies by passing the proxy endpoint into the browser launch options — you get full JavaScript execution and a residential IP.

Respect robots.txt and Rate Limits

Beyond the technical measures, staying within polite scraping norms reduces the likelihood of targeted blocking and protects you legally in many jurisdictions.

Conclusion

Avoiding blocks is not about finding a single magic trick — it's about layering the right tools:

  1. Choose the correct proxy type for your target (residential for maximum trust, ISP for speed + trust, IPv4 for dedicated identity, IPv6 for budget volume).
  2. Rotate IPs intelligently — per request, per session, or on error.
  3. Mimic human timing with randomized delays.
  4. Craft realistic headers and consider a headless browser for JS-heavy sites.
