Why do we need Web Scraping?


Web scraping is a technique that utilizes automated intelligence to quickly and efficiently collect large amounts of data from websites, rather than manually obtaining it. This process can save time and effort and is particularly useful for gathering large amounts of information. In this blog, we will provide detailed information about the process of web scraping to give you a better understanding of it.

What is Web Scraping?

Web scraping is a method of automatically gathering large amounts of data from websites, typically in HTML format. This data is then converted into a structured format using databases or spreadsheets for various purposes. Professionals can use various techniques for web scraping, including APIs, online services, or creating custom code. Many well-known websites like Twitter, Google, and Facebook offer APIs for accessing their data in a structured format. However, some websites do not provide such access, making web scraping tools necessary.

The process of web scraping consists of two parts:


    1. The crawler, an AI algorithm that searches the web for relevant data, and the scraper, which extracts the data from the website.

    1. The design of the scraper can vary depending on the project’s scope and complexity, allowing for efficient and accurate data extraction.

How Web Scraper Works?

Web scraping can be used to extract specific data or all data from a website, depending on the user’s needs. It’s more efficient to specify what data is needed so that the web scraper can complete the task quickly. For example, when scraping a website for home appliances, one might only want data on the different models of juicers available, rather than customer testimonials and reviews. The scraping process begins by providing URLs, then loading the HTML code for those websites. Advanced scrapers may also extract JavaScript and CSS elements. The scraper then extracts the specified data from the HTML code and outputs it in a format defined by the user, such as an Excel spreadsheet or CSV file, or other formats like JSON files.

Types of Web Scrapers:

There are several types of web scrapers available, each with its own advantages and limitations.


    • Local web scrapers: These web scrapers run on a computer using its own resources. They may use more CPU or RAM, which can result in slower computer performance.

    • Browser extensions: These web scrapers are added to the browser and are easy to use as they are integrated with the browser. However, their functions may be limited.

    • Software web scrapers: These scrapers can be downloaded and installed on a computer, providing more advanced features than browser extensions. However, they may be more complex to use.

    • Cloud web scrapers: These web scrapers run on the cloud, typically on a server provided by the company offering the scraper. This allows the computer to focus on other tasks as it does not need to use its resources to scrape the data.

Benefits of Web Scraping:

Web scraping can be used in various ways to gain a competitive edge in the digital retail market.
