How hard is it to catch real reviews? Try this trick.
Friends who want to pick Yelp merchant reviews to do market analysis, nine out of ten planted in the anti-climbing mechanism. Last week a cross-border friends and I touted, just grabbed 200 pieces of data account was blocked, but also received a warning letter from the platform. In fact, the problem is in the IP - with their own computer IP repeatedly request, not seal you seal who?
Normal proxy IPs don't work well either, Yelp is on it.Data Center IPSeal. We have tested that on average 30 requests will trigger a CAPTCHA if accessed with a server room IP. This is when theResidential Proxy IP, especially with US local home broadband IPs, the success rate doubles straight away.
IP Type | success rate | Average survival time |
---|---|---|
private IP | <10% | 20 minutes. |
Server Room Agents | 30% | 2 hours. |
Residential agent (recommended) | >85% | 12 hours + |
Hands-on agent matching
Demonstrated here in Python, the logic is similar in other languages. The key is toDifferent IP for each request, don't catch an IP and gripe hard.
import requests
from ipipgo import RotateProxy This is the key toolkit.
proxy_pool = RotateProxy(region='us', type='residential')
for page in range(1, 11): proxies = proxy_pool.
proxies = proxy_pool.get_proxy()
try.
resp = requests.get(
'https://www.yelp.com/biz/xxx/review_feed', proxies={'http': 'http': proxies()
proxies={'http': proxies, 'https': proxies}, timeout=10
timeout=10
)
Processing the data code...
print(f "Page {page} crawled successfully! Current IP: {proxies}")
except Exception as e.
print(f "This IP hangs, automatically switch to the next one: {proxies}")
proxy_pool.ban_proxy(proxies) Marks the IP as invalid.
Watch this.ipipgo.RotateProxyModule, a smart scheduling library we've encapsulated with our own services. It will automatically exclude invalid IPs, and can also filter IPs by state, for example, when catching New York restaurant reviews exclusively, it is more realistic to use local IPs.
A guide to avoiding the pit (blood and tears)
1. Don't kill yourself by requesting a frequency.Even if you use a residential IP, 10 requests in 1 second will still be exposed. Suggest random delay 2-5 seconds, in the middle of the night can be adjusted faster!
2. User agents should be rotated: Prepare 10 major browsers for UA random use, don't clear the Python request header!
3. CAPTCHA recognition leaves a way outCAPTCHA: Don't be hard on yourself, record the link for manual processing later!
4. Don't store data locally.: It is recommended to transfer directly to the cloud, accessing the storage service with a residential IP is easily exposed

– 7×24 technical support: The last time I had a problem at 3am, customer service gave me a solution in 10 minutes!
Frequently Asked Questions QA
Q: Will I be sued by Yelp?
A: It's not illegal to grab public data at a reasonable frequency, but don't grab users' private information. It is recommended not to exceed 5,000 entries per day
Q: Why is residential IP more expensive?
A: It's expensive to maintain! You have to sign agreements with countless households and ensure network quality. But with ipipgo's hourly billing model, catching data scenarios is actually more cost-effective
Q: Can I still use my blocked IP?
A: Our IP pool is updated daily with 30%, and the tagged IPs will be refrigerated for 7 days. It is recommended to match with automatic replacement module to save your mind
Q: Do I need to maintain my own IP pool?
A: Not at all! ipipgo's API automatically assigns available IPs and can also be set to exclude specific ASNs (e.g., identifying the data center operator)
One last rant: don't use free proxies on the cheap! Someone used a flagged IP pool before and ended up with a total loss of accounts. Professional things to professional tools, save time to analyze a few more bad reviews, maybe you can find the blue ocean market?
