Yelp Data Capture: Yelp Proxy Data Collection

Why do I have to use a proxy IP for Yelp data capture?

Engaged in Yelp data collection know, this platform anti-reptile mechanism thief ruthless. Directly with their own IP hard just, light is blocked heavy is permanently black. Recently, there is a catering analysis of friends, with their own broadband even climbed 3 hours, the next day even normal access to the pop-up verification code - how to do business?

at this momentproxy IPThis is where it comes in handy. To put it bluntly, it is to let different IPs take the blame for you, spreading the single request to multiple "vests". For example, if you want to capture restaurant data in Los Angeles, use the local residential IP to request in turn, the system will think it is a normal user browsing, which is much more reliable than the data center IP.

Don't Step on the Three Pits of Choosing Proxy IPs

There are many proxy services on the market, but 90% are not suitable for Yelp collection. Last year I tested a certain service provider that claimed to have millions of IP pools, and as a result, 6 out of 10 IPs were recognized by Yelp as crawlers, which was a pure waste of money.

This is a must.Exclusive Residential Agent for ipipgoThey have a real home network environment fingerprint on each IP. Last week's actual test caught 20,000 merchant information, the success rate stays above 98%, midway did not trigger the wind control at all.

Hands-on with ipipgo to grab Yelp data

Sign up for an ipipgo account first and generate an API key in the backend. It is recommended to choose the US residential IP package, and prioritize the target business area if you break it down by city. Here is a Python example:

import requests

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"
}

headers = {
    "User-Agent": "Mozilla/5.0 (Windows NT 10.0) AppleWebKit/537.36..."
}

response = requests.get(
    "https://www.yelp.com/biz/目标商家",
    proxies=proxies,
    headers=headers,
    timeout=15
)

Note three things:1. change a different UA header for each request 2. don't set the timeout lower than 10 seconds 3. immediately pause to change the IP when you encounter a CAPTCHA. ipipgo has an interface to automatically change the IP in the background, and it is recommended that you change the vest for every 50 requests.

A practical guide to avoiding mines

Don't think you can do whatever you want just because you're on a proxy, Yelp's anti-crawl monitors these behaviors:

• Click on the "Load More" button continuously.
• Page dwell time below 20 seconds
• Suddenly switching geographic locations

It is recommended to use random scrolling page + simulated click operation. For example, after grabbing the merchant detail page, first randomly browse 3-5 other pages, and then continue to collect the next target. ipipgo'sIP Survival TimeIt is recommended to control within 30 minutes, long time with the same IP will be blocked.
