G2 Review Capture Tool: SaaS Rating Capture API

How does the G2 comment grabber tool really work? Hands-on with proxy IPs to get your hands on data

Old iron people do market research, certainly encountered this situation: want to batch capture G2 platform product ratings, the results just climbed a few data on the blocked IP. this time on the need for proxy IP as a "cloak of invisibility", today we talk about how to use ipipgo's proxy service to deal with this problem in the vernacular.

Why does your crawler always get pulled by G2?

Many newbies tend to make two fatal mistakes:use one's own computer's IP address to do the hard workrespond in singingFixed frequency requestG2's anti-climbing mechanism is not vegetarian, found that the same IP high-frequency access, minutes to you to pull the blacklist. Last year, a SaaS friend wrote his own script to capture data, and as a result, the company's network IP was permanently blocked, and even normal access is a problem.

 Bug Demonstration (Don't learn!)
import requests
for page in range(1,100):
    response = requests.get(f "https://www.g2.com/products?page={page}")
     You'll get your IP blocked soon...

The right way to open a proxy IP

Here's where we have to bring out our godsend, ipipgo, who have three great dynamic residential proxies:

Focus on configuration tips:Random proxy cut per request + simulate real person intervals。建议设置3-7秒随机，别让平台看出规律。

 Example of correct posture
import requests
from ipipgo import get_proxy ipipgo's SDK
import time
import random

for page in range(1, 10): proxy = get_proxy(type='residential')
    proxy = get_proxy(type='residential') get residential proxy
    try.
        response = requests.get(
            url=f "https://www.g2.com/products?page={page}",
            proxies={"http": proxy, "https": proxy},
            timeout=10
        )
        print(f "Page {page} data fetched successfully!")
        time.sleep(random.uniform(3, 7)) random wait
    except Exception as e.
        print(f "Problem encountered: {str(e)}")
        ipipgo.report_failure(proxy) report failed IPs

A practical guide to avoiding the pit

Recently, a user feedback that the use of a proxy is still blocked, troubleshooting found three common problems:

1. The header information is not disguised.: Remember to add User-Agent, not Python's default!
2. The concurrency number is too high.: single thread recommended for newbies, add slowly once you're proficient
3. Didn't handle the CAPTCHA.: When you encounter a validation page to pause the collection, ipipgo's API supports automatic meltdowns

The QA that everyone is asking about

Q: Is it illegal to collect G2 data?
A: It is legal to collect public ratings as long as they do not involve private user data. But be careful to comply with the platform's robots.txt rules

Q: Which of ipipgo's packages is best?
A: Individual user selection"Green Pine Edition"(5GB/month traffic), business users directly on the"The Rock."With dedicated API gateway and failure retry mechanism

Q: Do free proxies work?
A: Never! Those open proxy pools have been tagged by G2 for a long time, using free proxies is like shooting yourself in the foot!

Finally nagging a word: data collection is a protracted war, choose the right proxy service provider will be half successful. ipipgo recently upgraded the IP pool cleaning system, new user registration also sends 1G test flow, there is a need for the old iron may wish to try.
