Off-Page SEO & Links

Authority Score

Quick Definition

Authority Score is Semrush's 0–100 metric for domain strength, similar to Moz's Domain Authority and Ahrefs's Domain Rating.

In context

All authority scores are third-party metrics, not Google ranking factors. They're shorthand for backlink profile strength but don't reflect content quality, technical SEO, or actual ranking ability for specific keywords.
