A custom domain is a personalized web address for a website or online platform. It replaces the generic domain provided by the hosting service with a unique and memorable domain name. Using a custom domain can help establish a brand identity, improve search engine optimization, and increase the credibility of the website.
For example, a business owner may choose to use a custom domain instead of a subdomain provided by a website builder to create a more professional image for their business. Custom domains can be purchased from a domain registrar and connected to the website through the hosting service.
