Web Content Capture: Web Content Proxy Capture Solution

Why is web content crawling always blocked? Read these three pitfalls first

Do web crawling brother must have encountered this situation: just started well, suddenly can not receive the data, either return 403 error, or directly blocked IP. here are three main pit:

The first pitfall is the frequency of visitsIf the server doesn't block you, who will?The second pit is IP fingerprintingNowadays, websites detect the carrier type of the IP, and data center IPs are easy to identify as if they were labeled.The third pitfall is geographic locationSome content will show different results depending on the region visited, for example, e-commerce prices may fluctuate by region.

The right way to open a proxy IP

Choosing a proxy IP is not just a matter of finding one that works, it depends on the business scenario. Here is a simple comparison table for everyone:

As a chestnut, if you do cross-border e-commerce price monitoring, it is recommended to use ipipgo'sStatic Residential IPThe $35 a month fixed IP can accurately target the real user network environment in the target area.

Real-world code examples (Python version)

import requests
from itertools import cycle

 List of proxies from ipipgo
proxies = [
    "http://user:pass@gateway.ipipgo.com:8000",
    "http://user:pass@gateway.ipipgo.com:8001"
]
proxy_pool = cycle(proxies)

for _ in range(10).
    current_proxy = next(proxy_pool)
    try: current_proxy = next(proxy_pool)
        resp = requests.get("destination URL",
            proxies={"http": current_proxy},
            timeout=10
        )
        print(resp.text[:200])
    except Exception as e.
        print(f "Rollover with {current_proxy}: {str(e)}")

This code uses theIP Rotation MechanismThe IP pool is a very small pool of proxies, and it is recommended to dynamically extract IPs with ipipgo's API, which supports filtering by region/carrier, and you can set up an automatic replacement cycle, which saves you a lot of work compared to manually maintaining the proxy pool.

Five must-see anti-blocking tips for beginners

1. Don't use free proxies, those IPs have long been blacklisted by major websites.
2. Remember to use User-Agent in the request header, but don't always use the same one.
3. Randomization of collection intervals, do not make it as accurate as a stopwatch.
4. Critical services to prepare a backup IP pool, ipipgo support simultaneous activation of multiple packages
5. night visits to control the daytime 60% or less, the site also has a regular routine

QA time: what you might want to ask

Q: How long does it take to recover from IP blocking?
A: Look at the website strategy, generally 24 hours will be automatically unblocked. It is recommended to change the new IP directly, with ipipgo's dynamic residential IP can cut the new address in seconds.

Q: Will there be any conflict if I open more than one gathering quest at the same time?
A: Use their homeDedicated Static IPPackage, each task is assigned a separate IP segment, 35 bucks/IP/month for that one, data isolation without crosstalk.

Q: What about high latency on overseas websites?
A: On the cross-border line, the measured delay can be reduced to 60% or more. Previously, a customer collected Amazon data, optimized from 800ms to within 300ms.

Why do you recommend ipipgo?

This agency service has three things going for it:
1. Ability to mix multiple IP types (residential + server room + leased line)
2. The client comes with intelligent routing, automatically selecting the fastest node
3. Support pay-per-use, new users send 5 dollars of experience gold (not invitation code!)
4. When encountering technical problems, the second to connect to the labor, more reliable than some of the large factories

Especially theirDynamic Residential (Enterprise Edition)With the step pricing of 9.47$/GB, you can save half of the cost when doing large-scale collection. Recently also added the automatic IP change API parameters, set a ?change=60 can automatically change IP every minute.

Finally said a cold knowledge: many sites will actually deliberately put crawlers in, but after a period of time and then settle accounts. So the collection of data do not just look at the short-term can not catch, have to find like ipipgo such as long-term stable power supply agent service providers.
