Why do you need a web scraper?

There are many different use cases where you might need to build a web scraper. All cases center around the fact that information on the internet is often disparate, but can be very valuable when collected into one single package. Often, in these cases, the person collecting the information does not have a working or business relationship with the producers of the data, meaning they cannot request the information to be packaged and delivered to them. Because of the lack of this relationship, the one who needs the data has to rely on their own means to gather the information.
