  • 29/08/2022

It’s difficult to expand your web scraping enterprise on your own. To prevent frequent mistakes, careful planning and preparation are necessary. It will take longer and be more difficult if you try to handle everything on your own.

How easy is it to prevent being stopped when online scraping, though? To learn more about the errors to avoid when expanding web scraping, keep reading.

Web scraping: What Is It?

Using software and automated technologies, web scraping is the process of collecting data from a website. To gather data for analysis, it is frequently used in BI (business intelligence) and data science applications.

This is a condensed explanation of web scraping. Let’s now examine the common errors to avoid during web scraping.

1. Leaving out Raw Data

Permanently storing raw data is a crucial stage in the data extraction process. All of the information in a file, including metadata and other specifics that are typically removed during file processing, is included in raw data. When attempting to find and comprehend trends in a dataset, for example, this additional information can be useful.

Another important step is protecting this raw data. Before beginning an inquiry, it’s important to double-check that your file-processing program removes this data.

2. Not Understanding the Ethical Consequences of Scraping

Many companies look down on scraping. When you are scraping their data, they frequently send you a warning letter. This is something you must bear in mind as you expand your scraping activities.

It could be preferable to scrape the data in a different way if the websites you’re scraping don’t want you to do so.

Consider scraping data from CAPTCHA-protected websites. To bypass CAPTCHAs, use an OCR provider. This is an acceptable way to grow your scrapping business.

3. Unsecure Proxy Servers

There are several varieties of proxies, so one will always fit your needs. Proxy servers capture data and reroute it to a different IP address.

Free proxies are great for web scraping but insecure. A malicious proxy may modify the HTML of the web page you request, transmit misleading information, and disconnect or block your IP address. Dedicated proxies make web scrapers reliable.

4. Unaware of Other Factors Needed to Scale Requests

Therefore, make careful to consider the requirement for a larger proxy pool, extra storage capacity, etc., while scaling out your web scraping. By doing this, you can make sure that your business can handle the added load without any problems. When expanding the number of queries, if you don’t also scale these other elements, your web scraping operation’s performance and stability will probably suffer.

5. Not Concerned about Headers

When you request a webpage, your browser sends a ton of headers. Headers reveal personal information about you. Therefore, It is crucial to be aware of them.

These headers can be used to give your web scraper a more human appearance. They must be copied and pasted into the code’s header element. Then, your request will appear to be coming from a legitimate browser.

Additionally, using User-Agent and IP rotations will extend the lifespan of your scraper. You can scrape any website, dynamic or static, using these methods.

6. Seeing Past IP Blocks

When web scraping, don’t forget about how to get around IP limitations. You most definitely don’t want it to happen.

But you need to take care of this problem as soon as you can. Because a rotating proxy service passes your requests across millions of residential proxies, you can avoid being blocked by using it.
