Search Engine Results Page Crawl API: Compliant Access to Ranking Data

Search Engine Results Page Crawl API: A Wild Ride Around the Threshold

Anyone who engages in data collection knows that search engine results pages (SERPs) harbor gold mines. But directly on the script to catch? Minutes to your IP blacklist. Today we will nag how to use proxy IP compliance, focusing on Amway our family!ipipgoThe service.

Why doesn't your crawler survive three episodes?

The platform's anti-crawl mechanism is stricter than a mother-in-law's censorship:
1. IP Access Frequency Monitoring: Single-IP high-frequency requests are straight-up cool
2. Request Feature Recognition: Incomplete Header or like a robot must die!
3. CAPTCHA bombing: Suddenly popping CAPTCHA interrupts the acquisition rhythm

Last week there is a SEO monitoring customers, self-built 20 server IP rotation, the results of two days all waste. Later changed ipipgo's dynamic residential agent, the average daily collection of 50,000 pieces of data stable as the old dog.

The right way to open a proxy IP

Comparison of common agent types on the market:

Focusing on dynamic residential proxies, this thing changes real residential IPs for every request, pulling in full camouflage. Take the ipipgo API for example, you get a brand new IP for every request:

import requests

proxy = {
    'http': 'http://用户名:密码@gateway.ipipgo.com:端口',
    'https': 'http://用户名:密码@gateway.ipipgo.com:端口'
}

response = requests.get('https://www.example.com/search?q=关键词',
                      proxies=proxy,
                      headers={'User-Agent': 'Mozilla/5.0'})

Real-world anti-blocking three-piece set

1. Frequency control: Don't send requests like a pile driver, randomly spaced 1-3 seconds apart!
2. Header disguiseRemember to include the parameters Referer and Accept-Language.
3. fail and try again: When you get a 429 status code, sleep on it for a while and try again with a different IP.

There's a pitfall to be aware of: don't use free proxies! Those IPs have long been marked rotten by the major platforms, use ipipgo's exclusive proxy pool to keep your IPs clean.

QA First Aid Kit

Q: Will I be blocked for harvesting Google Bing?
A: with a residential agent + control frequency is basically stable, measured ipipgo's North American node survival rate of 92% or more

Q: Do I need to maintain my own IP pool?
A: No need at all, ipipgo's API automatically assigns new IPs every time, and also has automatic failure detection.

Q: How do I break the CAPTCHA when I encounter it?
A: on the code platform with the agent, recommended XX code (here to hide the specific brand) can handle 3,000 times per hour to verify the

The doorway to choosing a proxy service

Don't just look at the price, focus on it:
- IP pool update rate (ipipgo adds 200,000+ residential IPs per day)
- Success rate guarantee (don't believe in verbal promises, you must sign an SLA)
- Does it support pay-per-use (small teams use as much as they can buy without waste)

Finally said a riotous operation: the collection task is split into multiple sub-tasks, with ipipgo nodes in different geographical areas to run in parallel, the efficiency is directly doubled. Before a customer with this method, three days to catch the end of the million keyword rankings, the father of the direct renewal fee for three years.
