Referral domains are domains that have at least one link from their websites/sources to your website.
Links from these sites are called backlinks. You can get multiple backlinks from one referral domain.
One of the key digital marketing jobs would be to analyse all the backlinks your website gets to ensure that the links to your site aren’t ‘toxic’. If you find toxic links it’s advised that you either ask them to remove the link first or if they refuse or are inaccessible add them to your disavow list to prevent your own website from appearing toxic.
