The first page of Google remains a major goal, but it’s important to separate useful metrics from myths. Domain Authority (Domain Authority, DA) is a metric created by SEO tools (especially Moz) to estimate how competitive a domain is in search. It is not a Google ranking factor per se, but it is useful as a comparative benchmark and for prioritizing SEO work.
Key takeaway: don’t go after “a big number”, but go after relevant organic traffic, leads and conversions. DA helps you understand if the foundation (especially the link profile) supports these results.
What is Domain Authority (DA)
DA is a 1-100 scale metric used to estimate a domain’s ability to rank in results (SERPs). It is an approximation made by SEO platforms, not an official Google score.
DA vs DR vs Authority Score
- DA (Moz): estimation of domain “strength”, strongly influenced by links and their quality.
- DR (Ahrefs): similar metric, with its own calculation methodology.
- Authority Score (Semrush): Composite score, different in method from Moz/Ahrefs.
Important: Do not directly compare DA with DR or Authority Score as if they were the same unit of measure. Consistently use a single suite of trending tools.
How domain authority is calculated
The exact methodology differs from one tool to another, but in practice the score mainly reflects:
- The number of referring domains, not just the total number of backlinks.
- Link quality (relevance, trust, editorial context, naturalness).
- Link distribution (diversity, anchors, landing pages).
- Spam signals or unnatural patterns.
The scale is generally logarithmic, meaning that it is much easier to go from 20 to 30 than from 70 to 80.
Why SEO matters in 2026
Even though DA is not used by Google as a ranking factor, it often correlates with better results because it reflects a simple truth: sites with a solid link profile and good reputation tend to perform better in search.
In addition, the competition for visibility remains huge: Ahrefs studies show that a very high proportion of pages do not get traffic from Google, usually due to lack of demand, lack of links or content that does not satisfy the search intent.
What authority score should you be aiming for?
The correct answer is: relative to your niche. A “good YES” for a local clinic, a B2B SaaS or a national eCommerce can look completely different.
- Compare yourself to direct competitors, not global giants.
- It follows the trend (steady growth) rather than an absolute value.
- Correlate with real KPIs: keyword positions, organic traffic, leads, sales.
How to Increase Domain Authority: Practical Steps (Updated for 2026)
1) Build backlinks by “link earning”, not by “link spam”
Target editorial links from relevant sites (industry, press, partners, reputable directories, local resources). Quality and relevance beat quantity. Avoid site networks, spam directories and “link packs”.
2) Create content worth citing
Content that attracts links naturally is usually one of the following:
- Definitive guides (complete, updated annually).
- Case studies with concrete results and clear methodology.
- Resources (templates, checklists, calculators, free tools).
- Original data (mini-reports, benchmarks, surveys).
3) Link internally “like an editor”, not like a robot
Internal linking helps both the user and the crawlers. Link important pages (services, categories, hubs) from relevant articles with natural anchors. A real bonus is that you also improve your distribution of authority between pages.
4) Audit links and treat “toxicity” with discernment
Periodically check the domains that refer to you. If you notice a pattern
