When the Default Domain Indexing setting is disabled, Google and other search engines will not index the super.site version of your site. This means it won’t appear in search results under that domain. However, visitors can still access your site using the super.site URL, your content remains publicly available, just not indexed for search.
Redirect Default Domain
When the Redirect Default Domain setting is enabled, any visitor who goes to your super.site URL will automatically be redirected to your custom domain. This helps consolidate traffic to your main domain and avoids duplicate content issues, which is also better for SEO.
