Deleted duplicate subdomain with heavy internal links – should I recreate it?
Posted by on February 28, 2026 at 10:27 pmLooking for some advice.
I had a duplicate subdomain that Google indexed. It had ~300 internal links on each page pointing to my main site. I decided to delete the entire subdomain and added a 301 redirect in my
.htaccessfile from the subdomain to the main domain.Immediately after deleting the subdomain, rankings dropped across a lot of pages that had internal links pointing to them.
It’s been over 2 months and rankings haven’t recovered.
My question:
Would it make sense to recreate the duplicate subdomain with the internal links pointing back to my main site, and then 301 redirect everything again? Or would that potentially make things worse?Trying to understand if I killed internal link equity or triggered something algorithmic.
Appreciate any insight.

Recreating it just to 301 it again probably won’t fix this.
If that subdomain was fully indexed and had 300 sitewide links per page, you basically removed a massive internal link network overnight. Even if it was “duplicate,” Google may have been treating it like a separate entity passing equity.
A 301 consolidates signals, but it’s not instant and not always 1:1, especially at that scale. Two months isn’t crazy long in that context.
Before rebuilding anything, I’d check:
Are all old URLs properly 301ing and not 404ing?
Did crawl frequency drop in GSC after removal?
Were any of those links actually driving traffic or external links?Recreating and redirecting again could look messy and unstable. I’d focus on rebuilding strong internal linking directly on the main domain instead of relying on a duplicate structure.
Out of curiosity, was the subdomain truly duplicate content, or slightly different templates/URLs? That detail matters a lot.
