Migration: Subdomain to Subfolder

Bring your subdomain into the main site.

Moving a section like blog.yoursite.com into yoursite.com/blog is a genuine URL change, even though it sounds small. Every address in that section moves, and it usually needs rebuilding inside your main site's platform, not just a DNS tweak.

The entity map

Every page, moved into the main site.

Every page in the subdomain, inventoried

We crawl the subdomain in full and cross-check Search Console for which of its pages actually earn impressions or clicks, so nothing valuable gets dropped when the section moves into the main site's structure.

Rebuilding the section on the main platform

A subdomain often runs on a different platform than the main site, for example a separate WordPress blog sitting on top of a custom-built main site. Moving it into a subfolder usually means rebuilding that content inside the main site's own templates, not just changing where it lives.

The redirect plan

A 301 from every old subdomain URL to its new subfolder path, deployed at cutover. Because the subdomain is typically retired afterward rather than kept as a separate live site, the redirect needs to cover the entire address space, not just the pages that get manually rebuilt first.

Tracking that must survive

If the subdomain had its own GA4 property or view, that data needs consolidating or archiving, and any conversion tracking scoped to the subdomain needs to be rebuilt against the new subfolder path.

What actually changes moving into a subfolder

If your subdomain and main site currently report separately

we note that Search Console's domain-level property can already group a subdomain's data with the main site's reporting, so combined reporting on its own is not always a reason to migrate, if the two sections work fine as they are.

If your subdomains are set up per country or region

we flag that as a different situation entirely, since a subdomain used deliberately for international targeting is not the same case as consolidating one section into the main site, and collapsing it into a subfolder without a proper international SEO plan can cause real problems.

If the subdomain runs a different CMS than your main site

we scope the rebuild honestly, since matching design, navigation, and functionality inside a new platform is real work, not a redirect exercise, and usually the larger part of the project.

What we cannot promise

We cannot promise the consolidated section performs identically to the standalone version on day one, since Google has to reprocess the whole thing under new URLs. What we can promise is a complete map and close monitoring after launch.

How the migration runs

01

Inventory and plan the rebuild

We crawl the subdomain, confirm which pages need to move, and scope what rebuilding that content on the main platform actually involves.

02

Build and test on staging

The section is rebuilt under its new subfolder path and checked against the redirect map before anything is made public.

03

Launch and monitor

Redirects go live at cutover, Search Console gets the new sitemap, and we watch closely as Google reprocesses the moved section.
