Simple Crawler: Zero-Code Data Collection Platform

Teach you how to use proxy IP to do data collection.

Recently, many friends asked me how to engage in web page data collection, and do not want to write code how to do? Here to teach you a wild way, with ready-made tools + proxy IP can be done. Do not underestimate this trick, many companies are secretly used, especially to do market research and competitive analysis.

For example, you want to monitor the price fluctuation of a certain treasure goods? The traditional method is easy to be blocked IP, this time you need a proxy IP torotational identityThe first thing you need to do is to get a new number to play the game. As if playing the game to open a small number, a number was blocked immediately change the new number then play.

 Pseudo-code example (actual tools have ready-made settings)
Capture task = set target URL
Cycles = 100 per day
Proxy settings = ipipgo_rotate_proxy()
Execute capture (capture task, proxy settings)

Why do I have to use a proxy IP?

Many websites have anti-crawl mechanisms, just like the neighborhood access control system. Assuming that you enter and exit from the same door 50 times a day, the security guard must check your documents. Proxy IP is equivalent to a myriad of passes, each time in and out of a different face.

Measured data: Without proxy IP, a website is blocked after 1 hour of continuous collection. With ipipgo's dynamic residential proxy, there is no problem for 3 days of continuous collection. Here we should pay attention to the selection ofHigh Stash Agents, like ipipgo's package will indicate the anonymity level, don't go cheap and buy transparent proxies.

Zero code collection tutorial

Recommended to use ready-made collection tools, such as a certain clawfish or octopus (note that not ads). Set up the key to three steps:

1. Enter the target URL in the tool
2. Find Proxy Settings in Advanced Settings
3. Fill in the address of the API provided by ipipgo.

Focus on the agent configuration parameters:

Question 1: What should I do if my proxy IP is slow?
A. Preferenceslocal carrier line的代理。比如你在广东，就选ipipgo的华南节点，实测能降60%

Problem 2: The acquisition was interrupted halfway through?
A: Check the proxy IP's(med.) recovery rateIt is recommended to set up an automatic detection mechanism. ipipgo background can check the online status of each IP

Question 3: Data capture incomplete?
A: It may be a problem with the way the site loads, try turning it on in the toolJavaScript Renderingmode, remember to use it with a proxy IP

Why do you recommend ipipgo?

After using seven or eight proxy services, I finally settled on ipipgo for three main reasons:
1. Real residential IP pools (unlike some server room IPs that are recognized as soon as they are used)
2. Exclusive supporthourly rate(Especially friendly to small projects)
3. Fast customer service response (last problem solved in 10 minutes)

They recently put on a newIntelligent RoutingFunction, can automatically match the fastest node. Measured collection speed increased by more than 2 times, the key is that the price did not increase, this point is quite conscientious.

Common QA for white people

Q: Is it illegal to collect data?
A: It is legal to collect public data as long as it does not touch personal privacy and sensitive content. It is recommended to look at the robots.txt file of the website before collection.

Q: How many IPs are needed per day?
A: 50-100 common items per day is enough. ipipgo's starter package is just enough, you can upgrade anytime if you don't have enough!

Q: Will proxy IPs be detected?
A: It depends on the quality of the proxy. I used a free proxy before and got banned in 10 minutes, but after I switched to ipipgo's high stash proxy, I was fine for a week straight!

As a final reminder, data collection is aboutthe principle of proportionalityIt's a good idea to set a reasonable collection frequency. Don't paralyze people's websites, set a reasonable collection frequency. If you really can't decide, you can directly copy the parameter suggestions given by the official website of ipipgo, and their technical team has tested the safety threshold.
