Web scraping is a process that enables computers to extract information from websites without their permission. It's the process of using scripts, known as web scrapers, to extract data from web pages and store it in databases and other software systems.
A web scraper is a tool that helps you to extract data from websites. There are a number of web scrapers available on the market today. The best web scraper will depend on how you plan to use it, what your budget is and what your preferences are.

If you're creating web-scraping agents for a significant number of distinct websites, you'll probably discover that about half of them are very simple, 30% are somewhat complex, and 20% are really difficult. It will be virtually impossible to collect significant data for a small percentage of the population.
Web scraping is an important part of the process since it allows for the rapid and effective extraction of data in the form of news from a variety of sources. After that, the data can be processed to get the necessary insights. As a result, it is also possible to maintain track of a company's brand and reputation.
