What Is Semrush Authority Score and How Is It Calculated?

Semrush Authority Score (AS) is a compound metric that measures the overall quality and SEO performance of a domain on a scale of 0–100. Unlike Moz's Domain Authority (which is primarily link-based), Semrush's AS incorporates three signal categories: link power (quantity and quality of backlinks), organic traffic (estimated monthly organic sessions from Google), and spam factors (signals of unnatural or manipulative link patterns).

The combination of link and traffic signals makes AS particularly useful — a domain with lots of backlinks but no real organic traffic scores lower than a domain with fewer but higher-quality links that actually drive rankings and visitors. This makes AS a strong proxy for genuine site authority.

Semrush AS vs. Moz DA vs. Ahrefs DR

  • Semrush AS (0–100): Factors in both backlinks AND organic traffic. More holistic, harder to game with low-quality links.
  • Moz DA (0–100): Primarily link-based. Older metric, widely recognized. Can be inflated by quantity over quality.
  • Ahrefs DR (0–100): Link-focused like DA but uses Ahrefs' own crawl data. Highly correlated with ranking ability for most sites.

How to Increase Your Semrush Authority Score

  • Earn backlinks from sites with high AS themselves — link quality matters more than quantity for AS growth
  • Grow organic traffic by improving rankings for target keywords — AS rewards real traffic signals
  • Eliminate toxic backlinks that inflate spam factors — use Semrush's Backlink Audit tool and Google's Disavow tool
  • Build topical authority through comprehensive content that ranks for clusters of related keywords

Frequently Asked Questions

What is a good Semrush Authority Score? +
AS interpretation varies by niche. AS 1–20: new/developing sites; AS 20–40: growing authority; AS 40–60: established, competitive; AS 60–80: major industry authority; AS 80+: dominant global brands. Always compare your AS against direct SERP competitors rather than global benchmarks. An AS 35 site competing against AS 25–30 competitors is in a strong position.
How often does Semrush update Authority Score? +
Semrush updates AS on a rolling basis as they recrawl the web — typically weekly for high-traffic domains and monthly for smaller sites. Major AS changes usually reflect significant link profile changes, organic traffic shifts, or spam signal updates. Expect 2–4 weeks for new link building efforts to begin influencing your AS, with meaningful movement over 3–6 months of consistent effort.
Is Semrush Authority Score used by Google? +
No — AS is a third-party metric created by Semrush, not used by Google internally. Google does not share its internal authority calculations with external tools. However, AS correlates strongly with ranking ability because it's built on signals (links, organic traffic) that Google also values. Use AS as a directional benchmark and competitive comparison tool, not as an absolute measure of your Google ranking potential.
