It’s been a subject of intense debates within the SEO circles whether it’s best to register a brand new domain name or create a sub-domain within an existing domain, while optimizing certain keywords. Well, each one has its pros and cons. Here I’ll tell you their advantages and advantages.
Advantages of a domain over a sub-domain:
Some people simply create sub-domains off existing domains, whenever they enter into a new niche, while others use standalone domains to target every niche. In terms of search engine optimization (SEO), both a standalone domain and sub-domain can be used, as long as you optimize the site properly for search engines. However, some search engines tend to lend slightly more weight to domains than sub-domains. Even though full-fledged domains are assigned a bit more authority than sub-domains, other SEO efforts are needed to enhance rankings in organic search results. While the main domain is generally assigned an IP address in a web hosting account, the domain only shares that IP, and banning the domain will also affect the sub-domain. And since search engines view sub-domains as different domains that are independent of their main domains, they don’t derive any juice from all the backlinks pointing to their main domains.
In a situation where you want to venture into a new business that is entirely different from your present business, a sub-domain is not a good option. For example, if your current business is car sales and want to go into SEO, purchasing a new domain name dedicated to search engine optimization seems to be the ideal thing to do.
Advantages of sub-domain:
Sub-domains have enormous advantages – keywords in the URL. Like you must have known, most keywords have already been registered as domain names by other people, and hence no longer available. Sub-domains enable a webmaster to put targeted keywords and key phrases in URLs, an option hardly available in new domain names.
In terms of cost, sub-domains do not require any form of formal registration and renewal as domain names do. So, it provides a way to have an online presence without spending any extra registration and web hosting cost. You can even sign up with a free web hosting provider and have your sub-domain up and running in a few minutes.
In summation, search engine algorithms assign a bit more importance to a full-fledged domain than a sub-domain, though not entirely. If you can afford it, register a new domain name for your website. But if you can’t, create a sub-domain in an existing site, and go from there. Whichever option you choose, you still have to do the necessary SEO for your site, which will help it to rank well on SERPs.
