Semrush Authority Score checker uitgelegd (met gratis alternatieven)
Wat Semrush Authority Score daadwerkelijk meet, hoe je de score van elk domein gratis kunt controleren, en de gratis insluitbare alternatieven die geen Semrush-abonnement vereisen.
What Semrush Authority Score is
Semrush's Authority Score (AS) is their composite domain-strength metric — a 0-100 score combining:
- Backlink profile strength
- Estimated organic traffic
- Spam score
- Natural profile signals (link diversity, anchor variety)
It was launched as a competitor to Moz DA + Ahrefs DR. Today it's one of the three industry-standard domain-authority metrics. Semrush's free public Authority Score Checker lets you look up any domain without an account — but you only get the AS number, no breakdown.
How AS compares to DA and DR
| Metric | Owner | Composite? | Free public lookup |
|---|---|---|---|
| Authority Score (AS) | Semrush | Yes (links + traffic + spam) | Yes |
| Domain Authority (DA) | Moz | No (link-graph only) | Via our free DA checker |
| Domain Rating (DR) | Ahrefs | No (link-graph only) | Via our free DR checker |
If you want a single composite score across all three perspectives, our free Trust Score combines DA + DR + age + HTTPS + Lighthouse signals into one 0-100 grade.
When AS matters (and when it doesn't)
AS matters most for organic-traffic-focused SEO work — guest posting, content partnerships, organic link building. It matters less for technical SEO (where Lighthouse score + Core Web Vitals dominate) or for paid placements (where direct traffic + audience match dominate).
