This process is commonly known as Indexing. Often internet sites like Google, Yahoo, Bing are search engines that make utmost use of this service to bring relevant content to the User’s Intent.
Web Scraping is a process in which you can gather data from any source. Be it a website, or an excel sheet with a trillion-attribute data. Thus, from a process perspective, Web Scraping is more of a contextualized process when compared to Web crawling. This is because using Web Scrapping you can extract data under a particular topic. Like extracting the costs of a certain product or reviews of certain products and similar examples as well.

Being Language neutral is a considerable expectation from the audience side, which can help businesses target websites all around the globe in multiple languages.

To carry out a perfect scrapping scenario, make sure that you have the apt third-party HTML libraries. These Libraries helps in sending HTTP requests to the URLs of the target website.
