Crawling Google Trends Data: Dual API + Crawler Solution

Getting a data headache? Try these two tricks for Google Trends

Recently, many cross-border e-commerce friends complained to me that Google Trends data sometimes work sometimes don't work, either loading slow like a turtle, or simply can't be displayed. In fact, this thing, to put it bluntly, is your network environment is being watched. Don't be in a hurry to scold, let's directly on the dry goods today, teach you how to use proxy IP + technical means to stabilize the data.

Why does your crawler always roll over?

Google Trends' anti-crawl mechanism is a lot more cockamamie than one might think. They look at three main things:Frequency of requests, IP addresses, browser fingerprintsThe first thing you need to do is to get the same IP address as the one you are using. Especially the IP piece, if you even use the same IP wild brush, minutes to give you a blacklist. I had a trainee who didn't believe in evil and used his office network to crawl data, and as a result, the entire company's IP segment was blocked for three days.

It's time to rely on proxy IPs tofight a guerrilla war. We recommend using ipipgo's residential proxy, they have tens of millions of real home network IPs in their IP pool, randomly switching each request, definitely more reliable than those crappy server room IPs.

The right way to open the official API

Let's start with the serious path, Google actually opened up theOfficial API.. After signing up for a developer account, you'll be able to check your data 5 times a day for free. There are two pitfalls to be aware of though:

1. Credit card must be tied (although no charge)
2. Domestic IP direct access will report 403 errors

This is where ipipgo's static residential proxy comes in handy. Add these lines of configuration to the code:

proxies = {
    "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(api_url, proxies=proxies)

One advantage of using their proxy is that the IP survival time is up to 24 hours, which is especially suitable for API calls that need to maintain the session. I have tested the continuous running for a week, the success rate remains above 98%.

Hardcore crawler program (use with caution)

If the API is too restrictive, you'll have to go the crawler route. Here's a configuration plan that's been personally tested to work:

I'm going to focus on proxy settings. It is recommended to use ipipgo's short-lived proxy package, every time you open a new page to change the IP. their API response speed thief, within 500 milliseconds to get a new IP, completely keep up with the pace of the crawler.

Frequently Asked Questions QA

Q: Can't I use a free proxy?
A: Brother you try to know, 10 free IP 9 failed, the remaining one may be marked as malicious IP. ipipgo although charge, but 1 dollar can buy 500 requests, really not expensive.

Q: What should I do if it always shows that the geographic location does not match?
A: In the background of ipipgo, select the "accurate positioning" function, for example, if you want to check the U.S. data, lock the residential IP of New York City, so that Google Trends will automatically show the local results.

Q: What if the data crawl is too slow?
A: open multi-threaded ah! With ipipgo's concurrency package, it is recommended to control 5-10 threads, the speed can be increased by 3 times still not blocked.

Tell the truth.

The data collection thing, don't ever think of saving trouble. Some of my friends buy cheap and inferior agents, and as a result, their accounts are blocked, data errors, and more losses. ipipgo I've been using it for half a year, and the best thing about it is that they've got a lot of good stuff.Real-time monitoring panelThe IPs can be seen at any time, and which ones are blocked are immediately replaced automatically.

As a final reminder, even if you use a proxy, you should control the frequency of requests. It is recommended to refer to this cadence:

• General inquiries: 3-5 per minute
• High-frequency acquisition: in conjunction with 10 IP rotations, no more than 20 times per minute

In accordance with this program to get, guaranteed you can stabilize the wool of Google Trends data grip.
