Web Data Extraction: The Definitive Guide

  • 29/06/2022

A method for gathering copious quantities of data from websites on the internet is called web data extraction (also known as web scraping, web harvesting, screen scraping, etc.). Website data can only be accessed by using a web browser and is not readily available for download. The web, on the other hand, is the biggest collection of free data, and since the internet’s beginnings, this data has been expanding at exponential rates.

Web data is very useful to e-commerce sites, media companies, research institutions, data scientists, and the government. It may even assist the healthcare industry with continuing research and disease outbreak forecasting.

Web data extraction applications:

1. Valuing intelligence

Given the tightening of online competition, pricing intelligence is an application that is growing in popularity every day. E-commerce sites constantly monitor their rivals by utilizing web crawling to get real-time price information from them and to improve the pricing on their own catalogs. This is accomplished by using web crawlers that have been designed to extract product information such as name, price, variation, and so forth. An automated system uses this information to analyze the pricing of rivals to determine the best prices for each product.

2. Brand monitoring

Today, every firm is aware of how crucial customer attention is to the expansion of its operations. If they wish to thrive in this competitive industry, it would be preferable for them to establish a good reputation for their brand. The majority of businesses today employ web crawling tools to keep an eye out for mentions of their brands and products on well-known forums, eCommerce sites, and social media platforms. In turn, this may assist them in staying up to speed with client feedback and resolving problems that can damage brand reputation as soon as possible. A customer-focused company will, without a doubt, see growth.

3. Market analysis

Unless you have a vast quantity of data at your disposal, market research is incomplete. Web data extraction is by far the most straightforward technique of gathering the data needed for market research, taking into account both the shortcomings of conventional methods of data capture and the abundance of pertinent data that is readily available online. Web data has improved as a source for market research as firms move from physical locations to online ones.

4. Competitive research

Before the advent of online scraping technology, it was never as easy to keep an eye on competitors. To gain the upper hand in the competition, it is now simple to install web spiders and closely monitor the actions of your rivals, such as the promotions they are running, social media activity, marketing plans, press releases, catalogs, etc. Crawls conducted in close to real-time go much farther and provide organizations access to rival information as it happens.

5. Sentimental evaluation

Sentiment analysis involves data that has been taken from websites where users may express their thoughts, criticisms, or evaluations of goods, services, movies, music, and other consumer-oriented offerings. Any sentiment analysis project would start with extracting this user-generated content, and web scraping is an effective tool for this.
