Everyday, we come across different forms of Data. Data that we analyze, understand, and sometimes, even collect. These three key ways of interacting with data form the bedrock of data analytics. In the current digital landscape of the world, data analytics has quickly grown to become an integral part of many businesses, with many using web scraping, AI, machine learning, and a host of other techniques and technologies to gather unique insight in hopes of improving their business.

That said, in this article, we’ll be taking a look at web scraping, one of the many techniques that businesses use to collect data from websites on the internet. We’ll be explaining what it is, why it's important, considering the legal implications of it, and getting into the details of how it works.

Let’s get to it!

What is Web Scraping?

If you've ever manually used your mouse to highlight certain details from a website, and then copied it to an Excel sheet, congratulations! You just practiced web scraping, albeit on a much smaller scale.

Web scraping, or data scraping as is sometimes referred to, is a data collection technique that is used to collate content and information from the internet, typically with the help of web scrapers.

If you’re wondering, web scrapers generally refer to software applications or bots that are programmed to navigate, retrieve relevant pages, and extract valuable information from web pages.

Using web scrapers is what differentiates web scraping from manually copying information from a website to an Excel sheet.

Web scraping is automated, and can copy millions of data automatically in mere minutes. Usually, this “millions of data” will initially be on a web page or web pages, before they are compiled to any offline storage of your choosing.

Is Web Scraping Legal?

Before delving further into the article, let’s address the elephant in the room: Is it legal to copy information from someone’s website? Is web scraping legal? Isn’t that a type of copyright infringement? Well, not exactly.

Web scraping isn’t hacking. It’s simply copying information that is already publicly available. information that humans can read, into a more machine-friendly format. So yes, it is legal. But there’s a catch.

While it is legal to scrape the web, there’s a limit to the kind of information you can scrape, and how you do it. Generally, you want to avoid personal data, and server overload. Your main focus should be on the publicly available information.

To further understand this concept, take a look at this example: while it is perfectly legal to take pictures with your phone, taking pictures of sensitive locations or confidential documents could result in bad legal repercussions.

Types of Web Scrapers

Now, let’s examine the types of web scrapers that exist. Web scrapers can be classified based on various criteria, including their origin, structure, and execution environment. Let’s look at these classifications:

1. Self-built vs. Pre-built Web Scrapers

  • Self-built Web Scrapers are scrapers that are programmed by expert programmers using Python
  • Pre-built Web Scrapers unlike self-built are already made, and are available for download. They often come equipped with advanced customizable options, and are suited to the needs of novices.

2. Browser Extension vs. Software Web Scrapers

  • Browser Extension Web Scrapers are integrated as extensions in browsers and are easy to run. However, they tend to be limited by the browser’s features and abilities. This type of web scrapers tend to function even better on antidetect browsers, but more on that latter.
  • Software Web Scrapers are downloadable and installable on computers. They are more complex than browser extensions, and they offer advanced features without the limitations tied to the browser's capabilities.

3. Cloud vs. Local Web Scrapers

  • Cloud Web Scrapers operate on off-site, or as the name implies, cloud-based servers provided by the scraper's company. Doing this takes the load off your computer and carries out the entire scraping process without the limitation of your computer’s hardware capabilities.
  • Local Web Scrapers run on your computer, and they utilize your software and hardware capabilities.

Different kinds of web scrapers all have their advantages and disadvantages depending on your use case. All in all, when you’re ready to begin web scraping, there will be one that suits your needs and expertise.

Tools You’ll Need to Start Web Scraping

Depending on the type of web scraping you want to carry out, there are three major tools you’ll need:

1. Antidetect Browser

Antidetect browsers utilize advanced technologies like data spoofing to safeguard the privacy of internet users. Some top-notch antidetect browsers, like the industry-leading AdsPower, will also offer multiple profile management. You can read all about antidetect browsers in this in-depth article.

Why do you need an antidetect browser for web scraping? Well, many websites use a lot of tracking technologies including cookies, digital fingerprints, and web beacons to gather information from their visitors. So while you’re scraping a website, said website could be gathering information about you. Hence the need for an antidetect browser.

For an antidetect browser that combines effectiveness with affordability, AdsPower is the go-to choice.

2. Python

Python is perhaps the most important programming language to learn if you’re trying to become an expert at many different types of data extraction and web scraping.

How to Get Started with Web Scraping

The specific approach to these steps may vary depending on your chosen tools, but for simplicity, we'll focus on the fundamental, non-technical aspects. Here are the sequential steps you should undertake:

Identify the URLs for scraping

While it may seem straightforward, the initial task is to determine the website you want scrape. For example, if your focus is on exploring customer book reviews, you may target relevant data from platforms like Amazon, Goodreads, or LibraryThing.

Inspect the webpage

Before coding your web scraper, it's crucial to understand what information it needs to collect. Right-clicking anywhere on the website's front end provides options like 'inspect element' or 'view page source.' This action unveils the site's underlying code, serving as the data source for the scraper. By the way, you can also use pre-built web scrapers.

Get to scrapping

Now that you've identified the relevant URLs and inspected the webpage structure, it's time to initiate the scraping procedure. This involves implementing the necessary code or utilizing web scraping tools to extract the desired data from the websites you've targeted. The specific method for carrying out this step may vary based on the chosen tools, but the fundamental goal remains the same: to systematically gather valuable information from the web.


Over time, web scraping has significantly evolved into a very important aspect of data analytics, and indeed businesses all around the world. It has empowered businesses to efficiently extract and analyze vast amounts of information from the internet. And as technology continues to advance, the role of web scraping is likely to expand.
