How long will it take for google to reindex 301 redirected url and refresh search results with new urls.

[swapnil12]

We have set up 301 redirects for some subdomains which we are planning to use, but then we changed our focus to main domain. Google has already crawled some of the subdomain pages. As it was duplicate content over subdomains and main domain, we have set up 301 redirects for all subdomains to redirect to the main domain.

We have set up 301 redirects a month ago, but some of the search results still show old URLs. Do you need something extra for google search results to refresh with main domain and remove subdomain URLs from google searches?

We need rankings to be passed new URLs.

Hi there! Tawny from Moz's Help team here.

Hm... this is more of an SEO question than product support, but I did some digging for ya! It sounds like it typically takes anywhere from a few days to a month or more for old pages that are 301 redirected to be recognized as such and stop being indexed. Here are some resources for further reading:

Yes, like Tawny said, it can take some weeks even months to reindex specially if your site doesn't change a lot along time.

Be patient
