TLDR
Every piece of information that we need in our daily lives can be obtained from the internet. You can extract data from the web and use it to make the most effective business decisions. If you want to programmatically capture specific information from a website for further processing, you need to either build or use a web scraper or a web crawler. There are multiple types of web crawlers, including a general purpose crawler, a focused crawler and incremental crawler that only crawls pages related to pre-defined topics.via the TL;DR App
