How does web scraping work?
Firstly, a web scraping bot simulates the act of human browsing the website. With the target URL entered, it sends a request to the server and gets information back in the HTML file.
Next, with the HTML source code at hand, the bot is able to reach the node where target data lies and parse the data as it is commanded in the scraping code.
Lastly, (based on how the scraping bot is configured) the cluster of scraped data will be cleaned, put into a structure, and ready for download or transference to your database.
