What is Web Scraping?

As we all know, the Internet is a repository of information. Several businesses make the most of web scraping. Indeed, a business can gather and analyze the data of its competitor’s website. You can implement price monitoring and adjust your pricing methods as well.

Web scraping is the process of extracting data from the Internet, websites, social media, blogs and so on. With the help of software tools, web scraping can be implemented easily. For instance, web scraping using Python is the most popular. 

How Does Web Scraping Work?

The very objective of a web scraper tool is to extract and store data for analysis. Usually, web scrapers are given URLs of websites from which you need to collect the data from.

Typically, a web scraper tool collects the data from the web pages. It is used for extracting the needed information. Then, the data is exported to an Excel spreadsheet or other formats for further analysis.

What is Web Scraping in Python?

Web scraping in Python automates the process of data collection from the Web. To start with, you need to gather the desired data. All you need is the URL of the target website from which you want to scrape the data. The data collected in the unstructured format needs to be transformed into structured ones to get useful insights. For this purpose, data is collected, stored and processed.

A Few Fundamental Steps in Web Scraping

If you want to extract data with web scraper using Python, follow the below fundamental steps:

• Select the URL from which you want to extract data
• Identify the data you want to collect
• Write the code
• Run and extract the data
• Store the fetched data 

The Web Scraping Process

When you run the code for web scraping, a request is sent to the URL given. Responding to the request, the server sends the data and lets you access and read the HTML or XML page. The code parses the HTML or XML page and identifies and extracts the data.

What are the Different Types of Web Scrapers?

Now that we have discussed the web scraping process, we shall go through a few types of web scrapers. Based on their functions, web scrapers are classified as follows:

Browser Extension

You can add these extensions to browsers such as Chrome, Firefox and so on. Further, you can integrate it into almost all browsers directly.

It is ideal for those businesses which want to extract small amounts of data. However, there is a drawback. It does not support Internet Protocol (IP) address rotations and scrapes only one page at a time.

The web scraper does the job! More importantly, it helps integrate advanced features. Therefore, cloud-based scrapers are useful for collecting large amounts of data.

Self-built Scrapers

It is possible to develop your web scraper tool. But at the same time, it requires the knowledge of programming language. The utilities and functionalities improve with the features added to your web scraper.

If you want more features, you may need more in-depth programming knowledge. This method is very easy to use and comes in handy. If you want to scrape similar pages, it becomes useful. Further, it is faster than manual implementation. 

Installable Software

We all know that the demand for data is continuously increasing. More businesses have started developing installable web scraping software on their computers. 

Most programs run on Windows and output the data in Excel spreadsheet, CSV or any other format. It is ideal for businesses that want to extract small and medium-sized data. Top of all, it can scrape several pages at a time.
