What is a referring domain?
If a blog links to you from 40 different posts, you have 40 backlinks but one referring domain. Links from many different, relevant sites generally indicate broader authority than many links from a single site.
Why it matters
Growth in referring domains from relevant sites is one of the clearest signs a site's authority is increasing, and comparing counts with competitors shows how big the gap is.
