Is it Bad for SEO to Use a Subdomain for Your Blog?

If you're responsible for promoting your organization, you've likely thought about Search Engine Optimization or SEO.

The topic of SEO seems to be top of mind for just about everyone we work with. There is a lot of good information available about SEO and unfortunately, there are some myths circulating.

One such myth is the "subdomain vs. subfolder" argument.
subdomain or subdirectory

Let's back up a bit and explain. There are a couple of ways to host a corporate blog on your website. One way is to place it under a subfolder (aka subdirectory) on your website. For example, if we went this route, our blog would live at the address "". This works fine and is usually how things are set up if your blog platform is part of your website CMS.

However, if your blog is hosted on a different platform than your website (such as HubSpot or tumblr, for example) then you might find it easier to set up a subdomain (called a CNAME) like "" or "" to host your blog. If you look up at your address bar right now you'll see that our blog is indeed hosted at "".

Here's the issue: many people today still think this makes a difference in your SEO strategy. They get all up in arms when they see blogs hosted on a subdomain and claim that the SEO Gods will punish your website for comitting such as tragic offense. They explain that the magical SEO juice will not "flow to your primary domain" and that this will hurt your search engine rankings.

Many years ago when the Internet was ruled by the machines and Google was a mindless robot, this may have mattered. And I'm being a bit dramatic. For fun.

However, today it just doesn't matter.

Google is smart enough to see both and as tied to the same website.

But don't take my word for it. Let's hear it from Matt Cutts, head of Google's Webspam team.
