Subdomain vs Subdirectory
Subdomains are separate sites under a main domain, while subdirectories are folders; each has distinct SEO implications.
Definition
The debate of subdomain vs subdirectory is a common consideration in SEO strategy. A subdomain (e.g., blog.example.com) is a separate section of your main domain, while a subdirectory (e.g., example.com/blog) is a folder within your main domain.
From an SEO perspective, using a subdirectory can help consolidate your domain's authority and improve overall rankings because all link equity is directed to the main domain. Conversely, subdomains can be useful for creating distinct sections of a website that target different audiences or serve different functions.
Why It Matters
The choice between a subdomain and a subdirectory can significantly affect your site's SEO performance. Search engines often treat subdomains as separate entities, which may dilute your site's overall authority if not managed correctly.
Example
If a business has a main site at www.example.com and creates a blog, choosing a subdirectory (example.com/blog) can help the main site rank better in search engines by pooling SEO benefits, as opposed to creating a subdomain (blog.example.com) which may rank independently.
