Definition
Authority Score is Semrush's estimation of a website's overall strength. It combines factors such as backlink quality, backlink quantity, organic search traffic and spam signals into a single number (0-100).
Why It Matters for SEO
While no third-party metric is perfect, Authority Score provides a quick way to benchmark your domain against competitors and to track progress over time. It's useful for vetting potential link partners.
