Web scraping or web harvesting refers to the extraction of data from websites. The extracted information is collected and exported into a format that is more useful for future retrieval and analysis. Generally, the extracted data is stored in a spreadsheet or a database. Web scraping can be done manually using software and can be tedious and boring, hence an automated process is implemented using a bot or a web crawler in most cases. Websites come in many shapes and forms, as a result, web scrapers vary in functionality and features. The main step is to fetch a page and extract information to be used for another purpose somewhere else.
