It is important to have domain names to help potential visitors find your website. Without assigned names for websites, we would only be able to access them by entering their IP address.
Since an IP address is a string of numbers like 87.249.281.92 it is obvious that it would be very hard to search for a site if we didn’t use domains to make things easier.
By adding keywords and brand names to domains, it is much easier for people to search for websites and find what they are looking for online.
