Open any SEO tool and you will see a number attached to almost every website: Domain Authority. It gets treated like a report card, obsessed over, and sometimes gamed outright. Here is what it actually is, where it comes from, and whether chasing it is still a smart use of your time in 2026.
What Is Domain Authority?
Domain Authority (DA) is a third-party metric created by Moz, scored from 1 to 100, that predicts how likely a website is to rank in search results compared to others. Higher generally means a stronger backlink profile and more established trust.
Domain Authority is a prediction tool built by an SEO software company — not a number Google calculates, stores, or looks at when ranking your site.
How Is Domain Authority Calculated?
DA is generated by a machine learning model that looks at dozens of factors from a site’s backlink profile: the number of linking root domains, the quality and trustworthiness of those domains, link diversity, and spam signals. The model is trained to correlate its score with how well sites actually perform in Google’s results.

Does Google Actually Use Domain Authority as a Ranking Factor?
No. Google has repeatedly and directly stated that Domain Authority (and similar third-party scores like Ahrefs’ Domain Rating) are not inputs into its ranking systems. Google uses its own internal signals — descended from PageRank and layered with modern quality and E-E-A-T evaluations — which are not publicly scored or exposed as a single number at all.
So Does Domain Authority Still Matter in 2026?
Indirectly, yes. While it is not a Google ranking factor, DA remains genuinely useful as a rough benchmark: comparing your site’s backlink strength against competitors, and tracking your own progress over time. The mistake is treating the number itself as the goal. Buying low-quality links purely to inflate a DA score tends to backfire — Google’s 2026 core updates have increasingly rewarded genuine brand signals and penalized manipulative link-building, regardless of what any third-party score shows.
How to Improve Your Site’s Real Authority
- Earn backlinks through genuinely useful content, original research, and digital PR.
- Build brand recognition so people search for you by name — a signal Google increasingly weighs directly.
- Use internal linking to spread authority from your strongest pages to newer ones.
- Periodically audit and disavow obviously toxic or spammy backlinks.
Domain Authority vs Other Metrics
Different tools use different scales that are not directly comparable: Moz’s Domain Authority, Ahrefs’ Domain Rating, and Majestic’s Trust Flow all measure similar concepts slightly differently. Never compare a DA score from one tool against a DR score from another as if they are the same metric — use one tool consistently to track your own trend over time.
Frequently Asked Questions
What is a “good” Domain Authority score for a new website?
Brand-new sites typically start around 1–10. Reaching 20–30 within the first year through genuine content and links is a realistic, healthy pace.
Can I increase my DA quickly?
Not sustainably. DA moves slowly because it reflects accumulated backlink trust — shortcuts tend to create risks that outweigh any short-term score bump.
Does DA affect my Google rankings directly?
No — but the underlying backlink quality it estimates absolutely does influence real rankings, since links remain one of Google’s core trust signals.
