Data scraping (also called web scraping) is the process of extracting information from websites. Data scraping focuses on transforming unstructured website content (usually HTML) into structured data which can be stored in a database or spreadsheet.
Unfortunately, there is no efficient way to fully protect your website from data scraping. This is so because scraping technology (also called data scrapers or web scrapers) simulates a human browsing the website thereby making the process of detection far more difficult.
Even if you block the IP address of a data scraper, this will not prevent it from accessing your website. Most data scraping bots use large IP address pools and automatically switch the IP address in case one IP gets blocked. And if you block too many IPs, you will most probably block many of your legitimate visitors.
One of the best ways to protect globally accessible data on a website is through copyright protection. This way you can legally protect the intellectual ownership of your website content.
Another way to protect your site content is to password protect it and charge your users for accessing the information. Therefore, even if someone wishes to scrape the data from your site, you are not a monetary loss.
