What is Parked Domain?

A parked domain is an added domain name (also called alias) to your current website. It is a common practice for various businesses to have multiple domain names parked to their primary one, thus open the very same website. It generates more traffic and it is often considered to be a helpful precaution against cybersquatters. 

In other words, having parked domains is having multiple domains that point to the same website and share the same content.
