Domains serve as the place you tell people to visit to come to see your website. Depending on the Site5 web hosting plan you choose, you can host multiple domains on a single account. You can also point your domains to specific locations or park your domains on a single website. If you have access to host multiple domains and websites, you will also gain email and website statistics for each.
A subdomain gives you the ability to put a prefix before your domain name. An example of this would be photo.yourdomain.com. Site5 provides you with the tools to quickly setup subdomains for your main website and for any other domains you are hosting with us. You also have full access to email and web statistic functionality with each subdomain you create and host at Site5.
