What Is a Good Domain Authority Score (And What It Actually Means)
Domain Authority gets cited constantly in SEO conversations — but the number itself is often misunderstood, misused, or treated as more definitive than it actually is. Here's what the score really measures, what counts as "good," and why the answer depends almost entirely on context.
What Domain Authority Actually Is
Domain Authority (DA) is a score developed by Moz that predicts how likely a website is to rank in search engine results pages (SERPs). It runs on a logarithmic scale from 1 to 100 — the higher the number, the stronger the site's predicted ranking ability.
The score is calculated using dozens of factors, but the most significant is link equity: how many external websites link to your domain, and how authoritative those linking sites are themselves. A single link from a high-DA news outlet carries far more weight than dozens of links from low-quality directories.
Important caveat: Domain Authority is a Moz proprietary metric — not a Google ranking signal. Google does not use DA when deciding where to place your pages. It's a third-party approximation, useful for competitive analysis but not a direct line into how search algorithms evaluate your site.
Other tools offer similar metrics under different names — Ahrefs uses Domain Rating (DR), Semrush uses Authority Score — and while they measure broadly similar things, the numbers won't match across platforms.
What the Score Range Looks Like in Practice
| DA Score | General Profile |
|---|---|
| 1–20 | New or very low-authority sites; limited backlink profile |
| 21–40 | Developing sites with some links; room to grow |
| 41–60 | Established sites with a solid backlink profile |
| 61–80 | Strong, well-linked sites — often larger brands or publishers |
| 81–100 | Major platforms, news giants, government/educational domains |
Sites like Wikipedia, YouTube, and major news outlets sit in the 90s. A regional business or niche blog might sit comfortably in the 30s and still outrank competitors in its specific category.
Why "Good" Is Relative, Not Absolute 📊
The most common mistake is treating DA as an absolute goal — chasing 70+ when the actual question should be: good compared to what?
The only DA score that matters is one that's competitive within your niche. If you're operating in a local service category where competitors average a DA of 25–35, a score of 40 is strong. If you're competing against established media publications in the 70s, a DA of 40 leaves significant ground to cover.
This is why SEO professionals typically use DA as a comparative benchmark, not a target in isolation:
- Competitive analysis — comparing your DA against direct competitors
- Link prospecting — evaluating whether a site is worth pursuing for a backlink
- Measuring momentum — tracking whether your own score trends upward over time
A site's DA also tends to rise slowly and non-linearly. Because the scale is logarithmic, moving from 20 to 30 is significantly easier than moving from 60 to 70. Growth in the upper ranges requires a sustained, high-quality link-building effort over months or years.
The Variables That Shape Your DA
Several factors determine where a site sits on the scale and how quickly it can move:
Backlink quantity and quality — The volume of unique referring domains matters, but quality weighs more heavily. Links from authoritative, relevant sites in your industry count for far more than mass links from unrelated or low-quality sources.
Site age and history — Older domains with clean histories tend to accumulate more links naturally over time. A brand-new domain starts at 1 regardless of content quality.
Niche and industry — Some industries generate links naturally (news, research, technology). Others — trades, local services, B2B niches — typically see lower DA ceilings across the board, which reframes what a competitive score looks like.
Toxic or spammy backlinks — A backlink profile filled with low-quality or manipulative links can suppress DA and, more importantly, create risk with search engines. Regular backlink audits matter here.
Internal link structure and technical health — While less impactful on DA specifically, overall site authority is influenced by how well a site is structured for crawling and indexing.
New Sites vs. Established Domains 🆕
A brand-new domain will almost always start with a DA of 1. That's not a problem — it's a starting point. What matters is the trajectory.
Sites that publish consistently useful content, earn genuine backlinks from relevant sources, and avoid manipulative link-building tactics tend to build authority steadily. Most legitimate new sites reach DA 20–30 within one to two years with active effort. Reaching DA 50+ typically requires a meaningful volume of high-quality inbound links and sustained content investment.
When DA Matters Less Than You'd Think
High DA doesn't guarantee ranking success on any individual page. Page-level authority, topical relevance, content quality, and search intent alignment all play roles that DA alone doesn't capture.
It's entirely possible for a DA 30 site to outrank a DA 60 site for a specific keyword if its content is more relevant, better structured, and more directly answers what the searcher is looking for. DA predicts general ranking potential — it doesn't determine it on a query-by-query basis.
This is also why a low DA score isn't automatically disqualifying. Many niche sites with modest authority dominate their specific topic areas because they've built deep, relevant content that serves a defined audience well.
The Gap That Determines Everything
Understanding the scale, the benchmarks, and the variables is useful groundwork — but what "good" looks like for any specific site comes down to who you're competing with, what industry you're in, how established your domain is, and what you're actually trying to rank for. Those factors vary too much from one situation to the next for a single number to mean the same thing twice.
