When Google looks to evaluate the authority of a site, it would much rather see 20 sites casting a digital vote for your site (which is really what linking is) than one site casting 20 digital votes. I’ve seen countless backlink profiles of sites with thousands of links originating from only a couple of dozen different sites, often the result of footer or sidebar links that perpetuate themselves every time a new page is created. If I could only use one metric when talking about a backlink portfolio’s health or when comparing two sites’ backlinks, I would use unique LRD’s over total links every time.
