What is a subdomain?
- Extensions of your root domain that you can use for a number purposes:
- Hosting content – setting up a blog – blog.yourdomain.com.
- Testing – a place to test offline content before pushing live to your final domain – staging.yoursite.com.
- Private content – we use training.webris.org to host internal training content for staff members.
Why do subdomains be important?
- They should be strategically planned into your SEO. For example:
- blog.yoursite.com should be set to “index” and have its personal set of directives (robots.txt and sitemap.xml) for proper search engine indexation.
- staging.yoursite.com should be set to “noindex” to avoid duplicate content penalties and searchers stumbling on content that wasn’t approved to go live yet.
