If you're familiar with SEO best practices, you might have heard of the noindex meta tag that tells search engines not to index a page.

This is particularly important if you're using Dub with a custom domain – specifically a subdomain – for your short links, since having them indexed could potentially have a negative impact on your SEO.

To prevent this, Dub automatically serves short links with a noindex response header when you're using a custom domain. This tells search engines not to index your short links, keeping them out of search results.

  1. Go to the Dub dashboard.
  2. Click on the Domains tab on the top navigation bar.
  3. Click on the button of domain that you want to set as thenoindex header for, which will open a dropdown menu.
