Data collection and annotation service: IP proxy solution for efficient data collection and annotation

Getting stuck with data collection? Let's see if you've stepped in these potholes first

Friends engaged in data collection understand that the biggest headache is that the target site suddenly gives you aIP blockingThe first thing I want to do is to get the best out of it. Last week there is an e-commerce comparison of buddies and I touted, just run two days on the blocked more than 200 IP, collection efficiency directly decimated. What's more troublesome is that some platforms will detectfrequency of visitsThe same IP accesses more than one direct pop-up captcha, and the data quality falls directly into the ditch.

Here's a hidden trap many people don't pay attention to - some websites recordIP Behavioral Characteristics. For example, if you always visit with a fixed IP at 3 a.m., or if you visit the exact same path every time, the system will return fake data to you even if you don't block the IP. Last year, we tested, the same time with a fixed IP collection of a travel platform, the return of the house price information 30% are expired data.

The right way to open a proxy IP

Truly reliable solutions have to play aroundIP Rotation StrategyThis is the first time I've seen this. Here to share a practical skills: the dynamic IP and static IP mixed use. For example, if you use a dynamic IP to do page traversal, you can cut to a static residential IP when you encounter key data extraction, which ensures collection stability and reduces the probability of being blocked.

 Python example: IP rotation using the ipipgo API
import requests

def get_proxy():
    api_url = "https://api.ipipgo.com/getproxy?type=dynamic&protocol=http"
    resp = requests.get(api_url).json()
    return f "http://{resp['ip']}:{resp['port']}"

proxies = {
    "http": get_proxy(),
    "https": get_proxy()
}
response = requests.get("destination URL", proxies=proxies, timeout=10)

Notice in the code thetimeout parameterSettings, this many people will ignore. It is measured that setting a timeout of 8-12 seconds can effectively avoid the traffic anomaly detection of the anti-climbing system, and improve the success rate of 40% or more than the default configuration.

Choosing the right service provider is half the battle

There are a variety of proxy IP services on the market, but there are threeiron ruleIt must be memorized:

1. Look at protocol support: at least dual protocol support for Socks5 and HTTPS
2. Look at the purity of the IP: Residential IPs have 3-5 times higher survival rate than server room IPs
3. Look at the movement control system: API responsiveness directly affects collection efficiency

The focus here is on ipipgo'sTK LineThis is their unique secret. We have tested the collection of a short video platform data, the ordinary agent success rate is only 62%, cut to TK line directly soared to 91%, and the data latency is reduced by about 200ms.

Configuration tips that even a novice can get started

Newbies often make the mistake of putting all their eggs in one basket.Four-step configuration method::

1. Selection of packages by type of business (don't go for the enterprise version if the standard version is enough)
2. API to get IP with a regional parameter (e.g. &country=US)

3. Setting the automatic IP change threshold in the collection tool (300-500 times/IP is recommended)
4. Regularly clear local cookies and cache

There's a detail that's easy to overlook--time zone matchingFor example, it is better to use the local IP segment from 10:00 am to 4:00 pm to collect American websites. For example, to collect American websites, it is better to use local IP segments from 10:00 am to 4:00 pm, so that the access timestamp looks more "normal". Previously, we used this method to increase the collection success rate of a news website from 71% to 89%.

Frequently Asked Questions

Q: What should I do if I always encounter CAPTCHA when collecting?
A: three directions of investigation: ① IP purity is up to standard ② access frequency is too high ③ request header information is complete. It is recommended to use ipipgo's static residential IP test, if still out of the verification code should be adjusted to collect strategies

Q: Why do I need both dynamic and static IPs?
A: Dynamic IP is responsible for "charging" to catch the list page, static IP is responsible for "attacking" to catch the details page. This combination not only reduces costs and ensures that the key data collection, just like the infantry and special forces in the war.

Q: How to judge proxy IP quality?
A: Prepare three test sites: ① can show the real IP detection page ② have a basic anti-climbing e-commerce site ③ need to log in the forum. Test IP stealth, availability and stability respectively, and test continuously for more than 24 hours.

Last but not least: after deploying the ipipgo solution to our customers, the average acquisition efficiency has increased by 2.3 times and the cost of IP loss has been reduced by 671 TP3T. especially for theircross-border rail lineIn the collection of multi-language sites, the delay can be controlled within 800ms, which is more than twice as fast as the regular line. Engage in data collection in this line, the right tool can really lessen the three-year detour.
