A Brief Introduction to Subdomains vs. Subdirectories

Before you dive into the nitty-gritty of SEO and blog placement, let's start with a basic understanding of what subdomains and subdirectories are.

Subdomains: A subdomain is a separate section of your website that acts as a distinct entity. It appears as a prefix to your main domain name, like "" or ""

Subdirectories: On the other hand, subdirectories are folders or directories within your main website. Subdirectories are typically used to organize and categorize content on your website.

With a clear understanding of subdomains and subdirectories, let's look at how each can affect your SEO.

Subdomains vs. Subdirectories for SEO

When it comes to SEO, there is no one-size-fits-all answer regarding whether to use subdomains or subdirectories. The choice you make should be based on your specific goals and circumstances. Analyze each approach's pros and cons.

Subdomains and SEO


  • Isolation of Content: Subdomains allow you to isolate specific content areas, which can be beneficial if you have distinct sections of your website with different target audiences or topics. For instance, if you run an e-commerce site, you might have a blog on a subdomain to keep it separate from your product pages.

  • Flexibility: Subdomains offer greater design and functional flexibility.

  • Keyword Opportunities: Each subdomain can target its own set of keywords, potentially increasing your overall organic visibility.


  • Diluted Authority: A subdomain's authority and backlinks may not directly benefit another subdomain since search engines regard it as a separate entity. Your domain authority can be diluted as a result.

  • Technical Complexity: Managing multiple subdomains can be technically challenging, requiring more effort and potentially higher hosting costs.

  • Cannibalization: There's a risk of keyword cannibalization when you have similar content across subdomains. This can confuse search engines and affect your rankings.

Subdirectories and SEO


  • Consolidated Authority: Subdirectories are part of the main domain, which means they share the same domain authority and backlinks. Any SEO efforts and backlinks directed at the main domain can benefit subdirectories.

  • Simplified Management: Managing content within subdirectories is typically easier and more straightforward. You have one central location for your website's content.


  • Less Isolation: Subdirectories do not offer the same level of isolation as subdomains. If you have drastically different content sections, it might be challenging to keep them separate.

  • Less Design Flexibility: While you can customize subdirectories to some extent, they may not offer the same design flexibility as subdomains.

  • Keyword Limitations: Subdirectories share the same set of keywords associated with the main domain, which can limit your ability to target specific keywords for different content areas.

How to Move Your Blog from Your Subdomain to Your Main Site

If you've decided that it's in your best interest to move your blog from a subdomain to your main website, here's a step-by-step guide on how to do it effectively while preserving your SEO efforts.

Step 1: Backup Your Subdomain Content

Before making any changes, ensure you have a complete backup of your subdomain's content. This includes all articles, images, and any associated databases. This precautionary step ensures that you can recover your content if anything goes wrong during the migration.

Step 2: Create a Subdirectory

On your main website, create a subdirectory where you want to host your blog content. For example, if your blog was previously on "," you might create a subdirectory like ""

Step 3: Copy Content

Transfer your blog content from the subdomain to the new subdirectory. Ensure that all images, media files, and internal links are updated to reflect the new subdirectory location.

Step 4: Set Up Redirects

As a means of maintaining SEO value and ensuring that visitors are directed to the new location, 301 redirects should be set up between the old subdomain URLs and the corresponding URLs in the subdirectory. It informs search engines that your content has been permanently moved.

Step 5: Update Internal Links

Review all internal links within your website and update them to point to the new subdirectory URLs. This includes links within your content, navigation menus, and footer links.

Step 6: Update XML Sitemap

Your website's XML sitemap should include the updated URLs from the subdirectory. You can submit this sitemap to search engines through their respective webmaster tools.

Step 7: Monitor and Test

Make sure you closely monitor the performance, rank, and traffic of your website after the migration. Test the functionality of all internal links and make sure there are no broken links or issues with the new setup.

Step 8: Inform Google

Google Search Console's "Change of Address" tool can be used to notify Google about the migration. As a result, Google will be able to recognize the change and update its index accordingly.

Internal Linking

Integrate internal links between your website's blog posts and pages. Besides improving user navigation, internal links help search engines understand the context and relevance of your content.
