Why do you have to use a proxy IP for e-commerce data?
Do e-commerce friends have recently come to ask me, why their crawler is always blocked? There is a buddy even worse, just on-line 3 days of price monitoring system was pulled by the platform black. In fact, this thing is like going to the supermarket to try to eat - you repeatedly take the same tasting bowl, the clerk will not drive you strange.
Here's the kicker.IP exposure issues. Ordinary crawlers use their own server IP to furiously scan data, and the platform knows at a glance that it is a robot that is messing with it. During last year's Double Eleven, a clothing brand used an ordinary IP to collect data on competing products, and as a result, it was blocked 17 times in one hour.
The Death of the Common Crawler
import requests
for page in range(1,100): response = requests.get(f'{page}')
response = requests.get(f'https://xxx.com/products?page={page}')
You'll get your IP blocked in no time!
How proxy IPs can be e-commerce data bodyguards
The real reliable method to learn guerrilla warfare, using a proxy IP to fight a shot for a different place. Here are some recommendationsipipgos dynamic IP pool, their residential proxies are particularly suitable for e-commerce scenarios. Last month, I helped a friend deploy a price comparison system, and after rotating with random IPs, it ran for 15 consecutive days without flipping.
| IP Type | Applicable Scenarios | Shelf life |
|---|---|---|
| Server Room IP | Short-term data capture | 2-4 hours |
| Residential IP | Long-term monitoring | 12-24 hours |
| Mobile IP | High-frequency requests | 6-8 hours |
Focusing on ipipgo'sIntelligent switching modeThe IP replacement frequency is automatically adjusted according to the defense strength of the target website. There is a time to catch a large platform promotional data, ordinary proxy 10 minutes on the knees, with their family IP hard to hold out until the end of the event.
Teach you to build a collection system by hand
Here's a real-life example: you want to do competitor monitoring for your own store, how can you do it safely?
import requests
from ipipgo import RotatingProxy
proxy = RotatingProxy(api_key='your key')
headers = {'User-Agent': 'Mozilla/5.0...'}
def safe_crawler(url).
for _ in range(3): retry 3 times
try: resp = requests.get(url)
resp = requests.get(url, proxies=proxy.next)
proxies=proxy.next_proxy(),
headers=headers,
next_proxy(), headers=headers, timeout=10)
return resp.json()
except Exception as e.
print(f'Failed {_+1}th time:', e)
return None
pay attention toRandomization request interval, don't make the whole thing as regular as a machine. It is recommended to add a random wait between 2-5 seconds, and with ipipgo's geo-location filtering function, it is more natural to visit with local IPs in the target area.
Old Driver's Guide to Avoiding Pitfalls
Three common mistakes newbies make:
- Rigor mortis on a single IP (like using the same key for all locks)
- Ignore the request header disguise (like wearing pajamas to a business meeting)
- Forgetting to deal with CAPTCHA (recommend accessing ipipgo's auto-coding service)
Last week came across a crying case: a seller deployed the crawler in the AliCloud Hong Kong servers, the results of the target platform directly blocked the entire Hong Kong IP segment. Later changed to ipipgoMulti-region hybrid IP poolsIt's the only way to solve the problem.
Data cleansing tips
Getting the data is the first step, the key is what to do with it:
- Price data to be filtered for promotional prices (use regular to match full price, discount tags)
- Evaluating data paying attention to comments (ipipgo's Sentiment Analysis API can help a lot)
- Inventory data in conjunction with historical trends (don't be misled by ad hoc replenishment)
To give a practical scenario: using ipipgo's24-hour long-lasting IPMonitor the competitor's inventory changes, found that the other party suddenly restocked 5,000 pieces, immediately adjusted their promotional strategy, the conversion rate on the same day to improve 37%.
Frequently Asked Questions QA

Q: Is data collection legal?
A: As long as the user's privacy and infringing content are not touched, the collection of public data is a normal business practice (consult legal counsel for details).
Lastly, a word of caution: do not just look at the price of choosing a proxy service, like ipipgo with aautomatic retry mechanismrespond in singingInvalid IP PayoutThe only thing that is really reliable. Last time they had an IP pool failure, not only automatically switch to the backup pool, but also according to the failure time triple compensation, this after-sales really no words.
