When using Semrush’s Backlink Gap tool, what does the "Weak" category refer to in the filtering?

The "Weak" category in Semrush's Backlink Gap tool identifies referring domains that have a low Authority Score. These are domains that link to your competitors but not to your site, and Semrush assesses them as having lower overall authority. While these links might not be as impactful as those from high-authority sites, they can still contribute to your backlink profile and offer opportunities for growth. The other options are incorrect because: "Referring domains with high Toxicity Scores" describes toxic backlinks, which Semrush identifies separately, not as "weak" in this context. "Referring domains sending more backlinks to your entered competitors than to you" is a general characteristic of all domains identified by the Backlink Gap tool, not a specific filter category. "Referring domains with poor backlink profiles" is too vague; "low Authority Scores" is the precise metric Semrush uses.
