Migrating Subdomains to a Subdirectory Structure
Explanation & Implementation Guide
Explanation
Hosting content on subdomains can create SEO challenges, as search engines may treat subdomains as separate from the main domain. This separation can reduce the benefit of consolidated domain authority, potentially impacting search rankings and organic traffic. By moving content from subdomains to subdirectories under the main domain, businesses can centralize their SEO efforts, often resulting in improved search rankings and visibility.
Implementation Guide
Identify Subdomains:
Use SEO tools such as Screaming Frog, SEMrush, Ahrefs, or Google Search Console to identify and catalog all subdomains associated with your website.
Evaluate Content and Traffic on Subdomains:
Review the content hosted on each subdomain, assessing traffic levels, engagement, and its role in your overall SEO strategy.
Plan Content Migration:
Select the content from subdomains that aligns with your main domain’s SEO goals, and plan its migration to corresponding subdirectories on the main domain.
Set Up 301 Redirects:
Implement 301 redirects from each subdomain URL to its new location in the main domain’s subdirectories. This helps retain link equity and prevents broken links.
Update Internal Links
Update all internal links across the site, including navigation menus, internal content links, and references, to point to the new subdirectory URLs.
Fixing the Issue
Monitor Indexing and Rankings:
Use Google Search Console and other SEO tools to track the indexing and ranking of migrated content. Address any issues quickly.
Update the XML Sitemap:
Add the new subdirectory URLs to your XML sitemap and submit it in Google Search Console to help search engines find and index the updated structure.
Notify Google of the Changes:
Use the Change of Address tool in Google Search Console to inform Google of the migration. This helps update Google’s index efficiently.
Monitor Traffic and Performance:
Continuously track website traffic, rankings, and user engagement to assess the impact of the migration on organic visibility and SEO performance.
