A referring domain is a unique website with at least one link to your site. For instance, several pages on one website, such as the homepage, blog and service page, can link to you but this counts as one referring domain and not three.
Referring domains are a vote of confidence to the search engines, as your content is more likely to be useful, trustworthy, and deserves to rank high in the search results when multiple authoritative websites link to it.
Search engines value backlink diversity because it indicates broader trust across the web.
Your website may have 500 links back to it, but if they’re all coming from just a handful of domains, that link profile is worth far less than those same links coming from 50 different high authority websites.
