Web scraping tools, or web scrapers, are software developed for data extraction. They’re the most customizable option and make the data extraction process simple and user-friendly, all whilst giving you unlimited access to the entirety of a website’s available data. Web scraping is as close as it gets to taking data harvesting matters into your own hands.

It means they don’t want anyone to scrape their data without explicit permission, even if it’s publicly available. If they have Robot Exclusion Standards in some or all parts of their website, avoid it. First and foremost, you should respect the website owner’s rights over their data. You should also avoid doing anything illegal with the data you harvest, such as unwarranted marketing campaigns and harmful apps.Įthical data harvesting is a slightly more complicated matter. In terms of legality, as long as you don’t go for black-hat techniques to get your hands on the data or violate the website’s privacy policy, you’re in the clear.

The first and last steps are fairly straightforward. Instead of only relying on official sources of information, such as previous studies and surveys conducted by major companies and credible institutions, data harvesting allows you to take data harvesting into your own hands.Īll you need is a website that publicly offers the type of data you’re after, a tool to extract it, and a database to store it. Data harvesting is the process of extracting publicly available data directly from online websites.
