When running an online business, one should comply with specific regulations. The European Union is special in a way that companies here should not only observe laws of their countries, but also the European Law. Three main documents regulating online businesses within the EU are E-Commerce Directive (Directive 2000/31/EC), the GDPR- General Data Protection Regulation (Directive 2016/679), and Consumer Rights Directive (Directive 2011/83/EU).
