Sub-Domains: What, When, & Where

Should you use a Sub Domain for your Landing Page URL?


Using a sub domain I would think that if the URL fits Google’s guidelines, that Google feels it’s more about the content of the page and how it relates to your ads and keywords. I really do not think It will not affect your quality score, but actually could improve your landing page if the keywords are the highlights in the URL. Try it and see, but….I really do not think it will hurt your search results.


What is a Subdirectory?

Subdirectories, also referred to as Folders, are any extesion of the main domain. For example http://offers.mywebsite/blog. The word “blog” is a subdirectory of the main domain.

How to Set Up a Custom Sub Domain:

A sub domain is the piece of your web address that is most likely “www” and appears in bold in the following example:http://offers.mywebsite/blog. Since the “www” sub domain is probably where you keep your main website, you can’t publish landing pages there. Instead, you’ll need to create a new sub domain that you can use.


When deciding what to choose for this new sub domain, keep in mind:

  1. It will be a real, visible part of your landing page address.

What is a Subdomain?

Every website has a subdomain and you can see it in the example, whereas the subdomain is “www“. It’s the section just before your main domain, or “top-level” domain, By default, each top-level domain has a subdomain of “www”.

You can replace the www with a different subdomain. One of the best examples I can give of an extremely successful subdomain website ishttp://offers.mywebsite/blog. After you go to this page, click to a different city. You will see the website looks exactly the same, but the URL has changed to a different subdomain. Each subdomain website is Search Engine Optimized for that city.

What is a Subdirectory?
