Crawler crawl big data accurate customer acquisition: proxy IP pool integration practice

When Crawler Meets Anti-Crawler: Why is Your Data Always Being Pinched?

Crawler friends understand that the biggest headache is that the target site suddenly gives you a403 BundleThe first thing you need to do is to get your hands on a script to monitor your competitors' prices. Last month, an e-commerce friend complained that they monitor the competitor's price of the script for three consecutive days was ban, the loss of more than 100,000 business opportunities. This is the time to sacrifice our killer -proxy IP poolThe

The average user may think that just any free proxy will work, but in real scenarios, those public proxies are like rotten cabbage in a food market-Eight out of ten are bad.The case of a recruitment platform capture last year showed that the success rate of using a self-built proxy pool was 27 times higher than that of a single IP. Last year, a recruitment platform crawling case shows that the collection success rate using a self-built proxy pool is 27 times higher than that of a single IP, which is the value of professional tools.

Hands on with building a reliable IP pool

Let's start with a misconception: not all businesses need to build their own IP pools. Professional service providers like ipipgo have already done all the dirty work for us.rationalization. Here's a practical program to share:

import requests
from ipipgo import IPPool Here we use the ipipgo SDK.

 Initialize the IP pool
pool = IPPool(
    api_key="your unique key", proxy_type="dynamic_resi", select dynamic_resi package
    proxy_type="dynamic_resi", select dynamic_residential package
    region_rules=["us", "jp", "kr"] specify region rotation
)

def smart_crawler(url).
    for retry in range(3).
        proxy = pool.get_proxy()
        try.
            resp = requests.get(url, proxies=proxy, timeout=8)
            if resp.status_code == 200: return resp.
                return resp.text
        except Exception as e: pool.report_failure(pool.report_failure)
            pool.report_failure(proxy) Automatically mark IPs as failures.
    return None

This program has three great tricks:

1. Automatic switching of geographic fingerprints
2. Failed IP Smart Fuse
3. Accurate control of flow costs

The devilish details of IP pool maintenance

Many newbies planted in the IP pool maintenance, here to share a few bloody lessons:

Special Reminder: If you are doing social platform collection, make sure to use residential IP. last year, we tested and found that the blocking rate of using data center IP is as high as that of residential IP.11 timesThe

Real-world case: how to use the right IP to save money

A cross-border e-commerce customer originally burned more than 20,000 per month on the proxy IP, changed to ipipgo's program after the cost down to 6800. the secret is:

- Dynamic residential for daily monitoring ($7.67/GB)
- Static residential for business-critical use ($35/IP per month)
- Add a cross-border line during the promotion

They've now increased their average lifetime per IP from 3 days to 27 days, and the secret is thatIntelligent Traffic Distribution Algorithm+ipipgo's IP Quality.

A must-see QA session for the little guy

Q: What should I do if my proxy IP is slow?
A: Prioritize checking the protocol type - do data collection with HTTP protocol faster than Socks5 20% or more. If it does not work, contact ipipgo technical support to open an exclusive channel.

Q: There are always a couple of sites that are dead on arrival that I can't crawl?
A: Try TK dedicated line agent, this line takes the internal channel of the operator, the success rate is higher than the ordinary line 40%.

Q: How do I choose the best value for my package?
A: high-frequency, low-concurrency selection of dynamic standard version, the need to maintain long-term sessions with static residential, enterprise-level projects directly to customer service to customize the program.

A final word from the heart: being in the data business is like fighting a guerrilla war.The IP pool is your ammo dump... Instead of wasting time on free proxies, you should use professional services to spend your energy on your core business. After all, we want data results, not to fight with anti-crawling mechanisms, right?
