Zillow Crawl: Real Estate Data Crawling Tool

Why do Zillow crawlers always get blocked? You may have missed this trick

Brothers who engage in real estate data crawling should understand that Zillow's anti-crawling system is stricter than the neighborhood gates. Last week, an old man complained to me that he had just written a crawler script that ran for less than 10 minutes, and his IP address was blacked out. This is not unusual, the key is to know how to bypass theirIP Recognition TrapThe

Why don't regular proxy IPs work well?

Many proxy service providers on the market provide IPs that are used to find three fatal injuries:

1. IP pool is too small (a few thousand is simply not enough for rotation)
2. survival time is too short (just bought and then failed)
3. Wrong type of protocol (using the wrong proxy protocol directly exposes the identity)

Especially with a site of Zillow's caliber, their wind control system recognizes theData Center IPThe characteristics of the It's like a security guard recognizing a delivery battery truck, accessing it with a regular server room IP and getting flagged in minutes.

Hands-on: getting customized solutions with ipipgo

Here we share a configuration plan that our team has tested to be effective (personally tested 3 weeks of continuous crawling without flipping):

import requests
from itertools import cycle

 Dynamic residential proxies provided by ipipgo
proxy_list = [
    'http://user:pass@gateway.ipipgo.net:3000',
    'http://user:pass@gateway.ipipgo.net:3001', ...
    ... Prepare at least 50 entries
]
proxy_pool = cycle(proxy_list)

for page in range(1,100): proxy = next(proxy_pool)
    proxy = next(proxy_pool)
    try: response = requests.get()
        response = requests.get(
            f'https://www.zillow.com/search/?page={page}',
            proxies={'http': proxy, 'https': proxy}, timeout=15
            timeout=15
        )
         Remember to add random delays and UA rotation.
    except.
         Automatically remove invalid proxies
        proxy_list.remove(proxy)

Here's the kicker, ipipgo'sDynamic Residential AgentsThere are two masterpieces:

1. Real user behavior simulation - Each requested IP comes from real home broadband
2. Automatic geo-location matching - Use the local exit IP if you want to climb the price of the house.

Parameter Configuration Pitfall Prevention Guide

It is not enough to have a good agent, the parameters are not adjusted well, as usual. These parameters must be set correctly:

Frequently Asked Questions QA

Q: I've already used a proxy IP and I'm still blocked?
A: Check if you are using a transparent proxy (use ipipgo's high stash proxy to hide the X-Forwarded-For header)

Q: What if I need to crawl the home prices of a specific city?
A: ipipgo supports filtering IPs by city, for example, to crawl Los Angeles data, choose their California residential IP pools

Q: How do I break the CAPTCHA when I encounter it?
A: Don't be rigid, immediately switch IP when encountering CAPTCHA (we suggest to cooperate with ipipgo's instant switching API)

Why do you recommend ipipgo?

We tested over a dozen providers and settled on ipipgo because of these three things:
1. ExclusiveResidential IP Dynamic Pool(Others use static IPs over and over again)
2. Automatic IP change per session (no need to clean cookies manually)
3. Support for customized crawler solutions on demand (their technical customer service can really solve problems)
