To understand that it is a subdomain, let's first see the parts of a URL. If we consider a simple URL it consists of 4 elements:
- Protocol domain: a communication protocol of the internet, which serves to protect the confidentiality and the integration of the users. That is to say, it is a system that encrypts the data of the users. In theory, all the pages should be served through the protocol https:// (HyperText Transfer Protocol Secure, hypertext transfer Protocol) to ensure a secure connection, especially if we manage the personal data of our users. If you do not encrypt the data, Google could not position the website in question.
- Yourdomain: Is a domain name extension that serves to organize the different sections of a web site, and categorize your content. Below, we will see the importance of this subdomain.
- Domain name: it is a unique name that is used to acknowledge a web page.
- Domain extension: it is the end that is located after the point and at the end of the URL that serves, among other things, to identify the geographic location of a web site.
What is the importance of a subdomain?
The importance of the subdomain web lies in the fact that each subdomain leads to a different web. That is to say, in the case of having two URLS as blog.elabsconsulting.com and www.elabsconsulting/blog, blog. and www. determine that these two URLS are two websites is different. It is very important to take this factor into account as Google will crawl as many websites as subdomains have.
Continuing with the above example, we are going to see the differences that we found between each subdomain:
- With respect to its nature:
- elabsconsulting.com: it is a website that is not part of elabsconsulting.com. Adding blog. we indicate that this URL is not within the web of Elabs Consulting.
- elabsconsulting.com/blog: is a folder within the web of elabsconsulting.com it, therefore, forms part of this web site.
- With regard to the authority web:
- elabsconsulting.com: external links that are pointing to this website does not transfer authority to elabsconsulting.com because it is a different web.
- elabsconsulting.com/blog: in this case, the external links yes that provide authority and relevance elabsconsulting.com.
- In connection with the positioning of the domain:
- elabsconsulting.com: keywords worked on this blog will have no effect in the domain of elabsconsulting.com.
- elabsconsulting.com/blog: to be part of the same web, all the keywords that are working on this blog, yes that affect your seo.
In the hypothetical case that we would like to work with SEO by using a blog in Elabs Consulting with keywords new, it would be interesting for this blog to be part of the web-site (elabsconsulting.com/blog).
When do generate more of a subdomain?
In most cases, doesn't make much sense to create different subdomains websites for the same domain name, whether it is advised that all services are grouped in the same web. Would only be useful when:
- A web page has many URLs (10.000 URLs approximately). As an example, we put the case of The "la Caixa", which consists of several sub-domains: press.la caixa.is portal.la caixa.it is, what.la caixa.it is, among others.
- When we don't want that the content will affect the positioning of the web. A very clear example would be a forum. Usually the pages of forum serve to build a community around a brand, but do not help to position a website.
