Cheap Crawler Agent: Cost-effective Crawler Agent IP Recommendation

First, why do crawlers need proxy IPs?

That is to say, who has not encountered the bad thing of IP being blocked in data collection? Website anti-climbing mechanism is now very fine, the same IP visit too often, minutes to you blacklisted. At this time, the proxy IP is like the resurrection coin in the game, change the IP can continue to wave.

To give a real example: there is a price comparison software buddies, using their own broadband IP to catch e-commerce data, the results of the third day was blocked to death. Later, he changedDynamic Residential Proxy for ipipgo, set the auto switching frequency and ran it for a month straight without flipping.

import requests
from itertools import cycle

 Proxy format provided by ipipgo Account:Password@ip:Port
proxy_list = [
    'user123:pass456@47.91.123.45:8080',
    'user123:pass456@138.68.234.67:8080'
]
proxy_pool = cycle(proxy_list)

for _ in range(10): proxy = next(proxy_pool)
    proxy = next(proxy_pool)
    try.
        response = requests.get('https://target-site.com',
                              proxies={'http': f'http://{proxy}'},
                              timeout=5)
        print(f "Successful access using proxy:{proxy}")
    except.
        print(f "This IP is banned ➡️ {proxy}")

Second, cheap no good? Don't step on these pits!

Proxy IP prices on the market range from not asking for money to hundreds of dollars, but cheap ≠ it works. Say a few real cases:

Here's the point:Never just look at the unit price! Some proxies look cheap, but 8 out of 10 do not work, the actual cost is higher. Like ipipgo's proxy pool comes with survival detection and automatic filtering of invalid IPs, which is a real money saver.

Third, how to choose a cost-effective agent? Remember these three hard indicators

1. IP purityThe IP address of the IP address is the IP address of a real person, not the IP address of a computer room, many websites will detect the IP address, and the IP address of a computer room is too obvious and easy to be recognized.

2. Toggle Freedom: Can you set whether to switch by times or by minutes. For example, if you collect a certain east, you have to switch once every 3 minutes, and a certain treasure may have to switch every request.

3. Channel StabilityThis is something that a lot of people will overlook. Some proxies have high and low latency, timeout halfway through the acquisition, and the data is missing.

Take the ipipgo.Intelligent Routing AgentTo cite a chestnut, they have a unique technology - according to the target site automatically match the optimal line. Collection of domestic e-commerce go telecom nodes, climbing international station cut Hong Kong exports, this trick can really save 30% above the cost of time.

Like ipipgo such a self-built server room service providers, although the price is not the lowest, but wins in the stability and worry. After all, the loss of collection business downtime, can be more expensive than the proxy fee is not?
