When using the Backlink Gap tool, what does the "Best" category refer to in the filtering?

In the Backlink Gap tool, the "Best" category identifies referring domains that are linking to your competitors but not to your website. This is crucial for competitive analysis because these are high-value backlink opportunities. If these domains link to your competitors, it suggests they are relevant to your niche and could potentially link to you as well, helping you close the "backlink gap." The other options are incorrect because: "Referring domains sending links to you, as well as to the entered competitors" describes shared backlinks, which are not the focus of the "Best" category for gap analysis. "Referring domains with the highest Authority Scores" is a general filtering option, not specific to the "Best" category's definition of a backlink gap. "Referring domains sending links to you, but not to your entered competitors" describes your unique backlinks, which are not what you're looking to gain from competitors.
