Video Transcript

A subdomain is essentially a subdomain of an existing domain on your hosting account. So for example, we were just looking at a site called CTLP-Lesson 4 which is a subdomain of So a subdomain usually precedes the domain name in the URL like this, CTLP-Lesson and you can see that here, that’s what this is., this CTLP-Lesson4 is my subdomain inside of the main domain which is

I do this for my lessons, right? CTLP refers to Customize Thesis Like a Pro and then I have hyphen lesson whatever for each lesson in that series. That just helps me keep all these kind of stuff straight.

And so, anyway, that is a subdomain. A subdomain is something that is preceded by this. Jared, I just actually answered the question, “Why do a subdomain?” I do a subdomain because… well, there’s a number of reasons actually. One of the reasons why you do a subdomain is that you don’t have to pay for it, right? So I could do a regular domain, and but I would pay domain registration fees for each one of those each year whereas subdomains do not require any additional… generally, do not require any additional registration fees.

Now actually, I do have a hosting account with a company called LFC hosting and I like very much for Windows hosting but they do charge you for every subdomain which seems to be almost Neanderthal but it doesn’t matter to me because I don’t need it there. But I would never host this kind of an account with them because I actually use lots and lots of subdomains.

And you might… well, another example of why you might do a subdomain is for example, This is my old architecture site, one of my old architecture sites. As a subdomain of is my blog and it’s in… I chose to configure that subdomain as looking like /blog here instead of being a .blog in front. Today, I probably wouldn’t do that. Today, I would probably do .blog but back when I created this back in… I don’t know, ’08 or whenever it was, that was the choice I made.

And so, this is a subdomain of the main website and this is the main domain. So that’s another reason why you might do a subdomain. You have a you know, you have a blog site and a regular static site.

And I think somebody just asked, “Is there a benefit to putting the subdomain in front?” Yeah, I think there is, actually. Maybe not necessarily with blog but I think that Google prefers or gives prominence to subdomains over and against subdirectories. And so you know, for example, you had a website that was you know, let’s see… well, if you could construct a subdomain and a domain name together, such that it sounded like a semantic URL like howtobuild… you know, I think that’s not a good example but… I’m drawing a blank here for the moment but there is a WordPress… I’m sorry. It is my understanding that Google favors subdomains over subdirectories and how much they favor them, I don’t know. But I think the conventional wisdom these days is if you have the opportunity, if it makes sense to do it as a subdomain rather than a subdirectory, you should do it as a subdomain. I can’t think of a good example of that at the moment though.

So anyway, that’s a subdomain.
