What Is a Good Domain Authority Score — And What Does It Actually Mean?

If you've spent any time in SEO, you've probably seen Domain Authority (DA) thrown around as a measure of how well a site might rank in search results. But what counts as a "good" score? The answer depends heavily on context — and understanding why is more useful than chasing a number.

What Is Domain Authority?

Domain Authority is a proprietary metric developed by Moz. It predicts how likely a website is to rank on search engine results pages (SERPs), scored on a scale from 1 to 100. Higher scores suggest stronger ranking potential.

It's worth being clear about something upfront: DA is not a Google metric. Google does not use Domain Authority in its algorithm. It's a third-party estimate, useful as a comparative tool but not a direct measure of search performance.

Other platforms have similar metrics — Domain Rating (DR) from Ahrefs and Authority Score from Semrush work on similar principles but use different data sets and calculations. Scores from one tool rarely match another for the same domain.

How Is Domain Authority Calculated?

Moz calculates DA using a machine learning model that incorporates dozens of signals, but the heaviest factors include:

• Linking root domains — the number of unique domains linking to your site
• Link quality — whether those links come from authoritative, trusted sources
• Link profile diversity — a natural mix of domains across industries and content types
• Spam score — toxic or manipulative links can drag the score down

The scale is logarithmic, not linear. Moving from DA 10 to DA 20 is relatively straightforward. Moving from DA 60 to DA 70 requires a substantially larger investment in link building and authority.

What Do Different DA Ranges Mean? 📊

Here's how DA scores are broadly interpreted across the industry:

Sites like Wikipedia, YouTube, and major news outlets routinely score in the high 90s. A small business blog launching this year might start at DA 1.

Why "Good" Is Always Relative

Here's the part most articles skip: a good DA score is defined by your competitive landscape, not by an absolute number.

If you're trying to rank for local plumbing services, you may be competing against sites with DA scores in the 15–35 range. A DA of 30 could be more than enough. If you're publishing content in the personal finance or health space, you're likely facing established domains with DA scores of 60, 70, or higher.

The only DA score that matters is whether yours is competitive relative to the pages currently ranking for your target keywords.

This is why SEOs look at relative authority rather than raw numbers. If you have a DA of 45 and every competitor on page one is between 30 and 50, you're in a reasonable position. If those competitors sit at 70+, the gap matters.

Variables That Shift What "Good" Looks Like

Several factors determine how meaningful your DA score is for your actual goals:

• Niche competitiveness — Finance, law, and health are notoriously hard. Local or niche markets are often far more accessible.
• Site age — Older domains with consistent publishing histories tend to accumulate more links naturally over time.
• Content quality and volume — A site with fewer, high-quality pages can outperform a high-DA site with thin content on specific queries.
• On-page SEO — DA measures off-page link signals only. Technical SEO, page speed, and content relevance operate independently.
• Link acquisition strategy — Paid links, link exchanges, or spammy directories can inflate or distort DA without translating to real ranking improvements.

A site with DA 35 and excellent on-page SEO, strong topical authority, and clean technical fundamentals can outrank a DA 55 site that has neglected those areas. 🎯

DA as a Diagnostic Tool, Not a Goal

One practical way to use DA is as a comparative health check, not a target to hit. When auditing competitors or evaluating link-building prospects, DA helps you quickly filter:

• Prospective link partners — Is this site worth pursuing for outreach?
• Competitor gap analysis — How far is your profile from sites currently outranking you?
• Site acquisitions or mergers — What kind of authority does a domain carry before you invest in it?

Using DA as the goal rather than the gauge leads to chasing metrics that don't necessarily correlate with actual traffic or rankings. Sites have grown to hundreds of thousands of monthly visitors with DA scores well below 50, while other high-DA domains see minimal organic traffic.

One More Thing Worth Knowing 🔍

DA scores fluctuate. Moz periodically recalibrates its model, which can cause scores across the entire index to shift — including yours — even if your link profile hasn't changed. A sudden DA drop doesn't always mean something went wrong. Comparing your score to competitors after any recalibration event gives a more accurate picture than tracking your raw number in isolation.

Whether a DA score is "good enough" for your specific situation comes down to your niche, your competition, your content strategy, and how you're using the metric in the first place. Those variables look different for every site.
