There are a lot of businesses who sidestep the use of subdomains because they consider them counterproductive in areas like the presence of a prefix name in front of their website, concern over indexing, as well as not liking the way it looks.
Subdomains are the second-level, or a substitute, of an actual domain. A domain name address shows as: www.johndoe.com, while http://blog.johndoe.com is representative of a subdomain name. Subdomains are always identified with “http://subdomain/maindomain.com”, rather than having a www in the beginning of their name.
Domains and Subdomains Ranking
Research shows subdomains rank quite well, and most people believe there’s no prejudice against them when search engine bots and spiders are ranking both regular domains and subdomains. It really doesn’t matter if you have a regular or subdomain name, as the most important thing is that your website delivers value to your target audience. Of course correct SEO keywords and optimization doesn’t go astray!
A lot of people are concerned if their main domain name gets banned, the same would happen to the subdomains and this is a legitimate concern. The key is to simply do the right thing so you don’t have to face this!
One other point to remember is if you want to sell your site you will have to give all the subdomains along with it, so try not to be tempted to use subdomains as a way of not paying for domain names if you feel you might one day sell some of your virtual businesses.
Personally I rarely will use a subdomain and just don’t see the need for it, but if it’s something you want to do because it suits your circumstances in the short and long term then there is really nothing stopping you.
