Yelp Web Crawl: Residential Agents Get Business Reviews

Why do you have to use a residential agent to climb Yelp?

Engaged in web crawling old iron know, like Yelp such a big platform anti-climbing mechanism than the cell gate control is also strict. Last year with a data center IP to climb, just sent a few requests to be blocked IP, angry I almost smashed the keyboard. Later foundResidential agents are the way to go, especially to climb merchant reviews, a situation that requires the simulation of a real person's actions.

As a chestnut, you want to crawl 500 reviews of a certain hotpot restaurant. If you use a normal proxy, Yelp will detect a large number of visits from the same IP segment and pop the verification code for you directly. But with ipipgo's residential proxy, each request comes from a real home network, just like different customers using their own wifi to brush reviews, the platform can't tell if it's a real person or a program.

How do you choose the right type of agent?

Agents on the market are divided into three categories, let's directly on the comparison table is clearer:

Focusing on ipipgo's one-of-a-kind specialty: their residential agency willAutomatic rotation of ASN numbersThis feature is very useful when crawling comments, as it disguises itself as a different ISP for each request.

Configuration Steps for Real-World

First install the Python environment, here is a demonstration with the requests library. Suppose you want to crawl reviews of Chinese restaurants in San Francisco:

import requests
from time import sleep

proxies = {
    'http': 'http://用户名:密码@gateway.ipipgo.com:端口',
    'https': 'http://用户名:密码@gateway.ipipgo.com:端口'
}

for page in range(1, 11): url = f"{page}".
    url = f "https://www.yelp.com/biz/xxxx/review_feed?page={page}"

    try: response = requests.get(url, proxies=proxies, timeout=10)
        response = requests.get(url, proxies=proxies, timeout=10)
         Remember to add a random delay here, not too regular
        sleep(1.5 + random.uniform(0, 2))
        print(response.json())
    except Exception as e.
        print(f "Error on page {page}: {str(e)}")

Key Points to Note:

1. Get it in the ipipgo backendDynamic authentication informationTheir authentication methods are automatically updated on a weekly basis
2. Don't set the timeout to more than 15 seconds, or you'll be easily flagged by the anti-climbing system.
3. Random delays are recommended at uneven intervals, such as between 1.5 and 3.8 seconds

Common Rollover Scene QA

Q：Why was I blocked even though I used a proxy?
A: 80% of the time the session is not handled properly, each request has to bring a new cookie. suggest using ipipgo'ssession hold functionThey have a X-Session-ID header parameter that specifically addresses this issue.

Q: What should I do if the crawling speed is too slow?
A: You can open ipipgoConcurrent Channel PackageThe maximum support is 50 IPs requesting at the same time. But be careful to control the request interval, don't hang the other server.

Q: How do I break the CAPTCHA when I encounter it?
A: This is the time to offer up ipipgo'sMan-Machine Validation SolutionsThey have a smart recognition system that automatically switches between high reputation IPs. if you can't do it, just pause for half an hour and let the proxy pool refresh itself.

Say something from the heart.

Last year, I used a free proxy to climb Yelp and was warned by the platform with a lawyer's letter. Then I switched to ipipgo and found that professional service really saves my heart. Their customer service has a hidden feature-Scenario Customization ServiceIf you want to crawl a website, tell them the type of website you want to crawl, and the technical team will help you to adjust the proxy parameters.

Lastly, a reminder: although it is not illegal to crawl public data, do not engage in DoS attacks that kind of naive batch operation. Use ipipgo'sIntelligent flow control functionThe data can be obtained both securely and consistently over time by setting up a per-minute request limit.
