We define web scraping as the process of extracting data from websites. It involves using web scraping software to access pages and collect structured data from them. With this technique, you can capture information quickly, and then store it in a database, spreadsheet, or any other place for further analysis. So, web scraping means a highly efficient method for collecting large volumes of data.

The legality of web scraping depends on the website's terms of service, the nature of the data extracted, and how it's used. Generally, fetching publicly accessible data for personal, non-commercial purposes is considered legal web scraping. However, scraping can violate terms of service or copyright laws if it involves copyrighted material, private databases, or is done without authorization. Always check local web scraping laws before engaging in this activity

To do web data scraping, you've got to deploy web page scraping tool or scripts that send requests to websites and then parse the HTML code to extract data from website. This data is then typically converted into a structured format—CSV, Excel, or JSON. The process of scraping the web usually involves navigating web pages, identifying and extracting relevant data, and handling errors or changes in website layout to maintain data accuracy.

Web scraping is used for a variety of purposes. B2B data scraping is particularly popular among businesses that rely on the exchange of data like background check companies. It's also a go-to solution for companies that perform in highly competitive markets—ecommerce, finance, etc. Additionally, web data extraction is employed in academic research to collect large datasets from public sources.

There are numerous web scraping tools available, from simple browser extensions to comprehensive web page scraping software. They allow users to extract data from any website.

Choose the best web scraper appropriate for your skill level and web scraping project's needs. Write the scraper to send requests and parse the HTML to extract the data you need. Save the scraped data into a structured format—CSV, Excel, or a database. Implement error handling, manage IP bans, and solve CAPTCHAs if necessary. Always ensure you comply with legal guidelines and the website’s terms of service.

Web crawling vs web scraping are related but serve different purposes.
