Domain Authority is one of the most searched, most quoted, and most misunderstood metrics in SEO. With nearly 3,000 impressions and zero clicks, the current version of this page is getting found but failing completely to earn a click, which means the title, meta description, and content depth aren’t matching what searchers actually want. The GSC data tells a clear story: people searching for “moz domain authority,” “what is DA on moz,” “how does moz calculate domain authority,” and “partner accuracy factors on moz” want authoritative, specific answers, not a general explainer. This guide covers exactly that: what Domain Authority is, how Moz calculates it, what the scores actually mean, what the “partner accuracy factors” signal tells you, and how to use DA as a practical SEO tool.
What Is Domain Authority?
Domain Authority (DA) is a proprietary score developed by Moz that predicts how well a website is likely to rank in search engine results pages. It ranges from 1 to 100, with higher scores indicating stronger predicted ranking potential. The scale is logarithmic; moving from DA 20 to DA 30 is significantly easier than moving from DA 60 to DA 70.
Moz created DA as a comparative benchmark, not an absolute quality score. Its primary use is evaluating your site’s ranking potential relative to competitors. If you and a competitor are targeting the same keywords and they hold DA 55 while you’re at DA 38, that gap represents the authority advantage they hold advantage built primarily through backlinks from other sites.
One point that cannot be overstated: Domain Authority is not a Google ranking factor. Google does not use Moz DA in its algorithms. Google has never referenced it and has no involvement in its calculation. The reason DA correlates with actual rankings is that Moz trained its model against real search results, and the underlying signal it measures link profile strength overlaps with what Google actually evaluates. The metric is a proxy, not a direct input.
What Is DA in Moz: The Exact Definition
In Moz’s own framework, DA specifically measures the strength of a domain’s entire link profile as a predictor of ranking ability. The score is generated by a machine learning model that Moz trains against Google’s actual search results.
Key properties of Moz DA:
- Score range: 1–100
- Scale type: Logarithmic (gains get harder as scores increase)
- Primary input: Backlink profile (number of links, quality of linking domains, link diversity)
- Secondary inputs: Root domain count, MozRank, MozTrust
- Update frequency: Moz refreshes DA scores as its index crawls and re-evaluates the web
- Comparative use only: Scores only mean something relative to competitors in your niche
A new domain starts with a DA of 1. Wikipedia and Google sit near DA 90+. Most small and medium business websites fall between DA 15 and DA 45.
How Does Moz Calculate Domain Authority?
This is the question the GSC data shows people asking most: “how does moz calculate domain authority” received 61 impressions at position 58. The current content doesn’t answer it with enough specificity to rank. Here’s what Moz’s calculation actually involves:
The Machine Learning Model
Moz uses a machine learning algorithm trained on tens of thousands of actual Google search results. The model is designed to find the combination of link signals that best predicts where pages rank. When Moz updates the model, every site’s DA can shift even if your backlink profile didn’t change because the calibration of the entire scale resets.
Link-Based Signals That Drive DA
Linking root domains is the single most important factor. The number of unique domains linking to your site carries more weight than the total number of backlinks. Ten links from ten different domains outweigh 100 links from one domain. This is why link velocity and link diversity matter so much for long-term DA growth.
MozRank measures the link popularity of your site, essentially how many links point to you and how authoritative those linking pages are. It is Moz’s version of the original PageRank concept. A link from a DA 80 site transfers more MozRank than a link from a DA 20 site.
MozTrust measures how close your backlink profile is to inherently trusted seed sites — think government domains, universities, major news publishers. Links that flow from trusted seeds carry higher MozTrust and boost DA more than links from sites further removed from that trust chain.
Link equity distribution across your domain also matters. A site where authority is concentrated on one or two pages scores differently than a site where strong links point to dozens of pages.
Anchor text diversity and the overall health of your link profile influence the score. Spammy or manipulative anchor text patterns can suppress DA even with high link volume.
What DA Does NOT Include
Moz has confirmed that DA does not factor in:
- Traffic volume or search clicks
- Social media signals
- Google Analytics or Search Console data
- Content quality or word count directly
- On-page SEO elements like title tags or meta descriptions
DA is almost entirely a link-based score. Content improvements, technical SEO fixes, and page speed improvements do not move DA directly only changes to the backlink profile do.
What Are Partner Accuracy Factors on Moz?
This query “partner accuracy factors on moz” appeared 141 times at position 5.65, making it the third-highest impression query and one of the closest to ranking. The current blog doesn’t address it at all, which is why it’s stuck.
Partner accuracy factors is a term that appears in Moz’s interface and documentation in reference to how accurately DA predicts rankings for a given site’s competitive environment. When Moz assesses accuracy, it looks at how well a site’s DA score correlates with its actual rank performance across a set of target queries.
The key factors Moz considers in this accuracy assessment include:
- Niche competition density: DA predicts rankings more accurately in competitive niches where backlinks are the dominant differentiator. In thin-competition niches, a low-DA site can outrank a high-DA competitor purely on content relevance.
- Backlink profile naturalness: Sites with diverse, natural link profiles show stronger accuracy correlation than sites with link profiles that show signs of manipulation.
- Index freshness: If Moz’s crawler hasn’t recently indexed a site’s new backlinks, the DA score may lag behind the site’s actual current authority.
- Spam score interaction: High spam scores on linking domains reduce the accuracy of DA as a predictor for that specific site’s rankings.
In practical terms, when you see “partner accuracy” referenced in Moz tools, it’s telling you how confident the model is in DA as a ranking predictor for that specific domain and competitive set. Low partner accuracy means the DA score is a weaker signal for that site; its rankings may diverge from what DA would predict.
Domain Authority vs. Page Authority
Two distinct metrics; two different things to track.
Domain Authority (DA) reflects the ranking potential of the entire domain, every page on inshalytics.com collectively. It is determined by all backlinks pointing to any page on the domain.
Page Authority (PA) measures the ranking potential of a single URL. It uses the same methodology as DA but is scoped to individual page-level links. A homepage typically carries the highest PA on a site because it tends to receive the most external links.
A high-DA domain does not automatically give every page strong PA. A page on a DA 60 site that has zero external links pointing to it, and no internal links sending authority its way, may rank poorly even though the domain is strong. This is why internal linking strategy matters it distributes DA across your pages, effectively lending domain-level authority to individual URLs.
The implication for content strategy: earning backlinks to your domain’s homepage or pillar pages raises DA. Building internal links from high-PA pages to newer content gives those new pages a ranking head start.
What Does a Good Domain Authority Score Mean on Moz?
Context is everything. A DA score means nothing without competitive comparison.
| DA Range | Typical Profile |
|---|---|
| 1–15 | New domains, minimal link profile |
| 15–30 | Small businesses, early-stage sites with some link activity |
| 30–50 | Established sites, consistent content + moderate link building |
| 50–70 | Strong publishers, national brands, authoritative niche sites |
| 70–90 | Major media, large corporations, high-authority directories |
| 90–100 | Google, Wikipedia, Facebook, government domains |
What counts as “good” depends entirely on what your competitors score. If every competing site in your niche sits between DA 25–35 and you’re at DA 42, you’re well-positioned. If your competitors average DA 60 and you’re at DA 35, the authority gap is significant and link building must be a strategic priority.
Moz’s own guidance is clear: use DA for competitive comparison, not as an absolute target. Chasing a specific DA number as a goal misses the point. The goal is to have higher DA than the competitors you’re trying to outrank for specific queries.
Why Domain Authority Matters (and Where It Doesn’t)
Where DA Is Genuinely Useful
Competitive benchmarking. Before targeting a keyword, check the DA of sites currently ranking in positions 1–5. If they’re all DA 60+ and you’re at DA 22, that keyword is a long-term play, not a quick win. Knowing this upfront prevents wasted content investment.
Evaluating link opportunities. When assessing a guest post site, directory listing, or press mention, DA gives you a quick read on whether that link will carry meaningful link equity. Aim for links from sites with DA higher than yours, ideally in the same topical space.
Tracking SEO momentum. If your DA trends upward over 12–24 months, your link-building is working. If it’s flat, your acquisition is keeping pace with what you’re losing — not gaining ground.
Evaluating site acquisitions or partnerships. DA gives a rapid authority read when assessing whether a website, media property, or content partner is worth engaging.
Where DA Falls Short
DA doesn’t measure content quality, E-E-A-T, user experience, or search intent alignment. A site can hold DA 60 and rank for nothing relevant because its content doesn’t match what users are actually searching for. A DA 25 site can consistently outrank DA 50 competitors on local and long-tail queries where the competitive set is weaker. Never use DA as a sole ranking predictor.
How to Improve Your Domain Authority
DA improvement is a byproduct of building a legitimate, strong backlink profile. There are no shortcuts. These are the levers that move the score.
Earn Links From High-Authority Domains
A single backlink from a DA 75 site moves DA more than 50 links from DA 15 sites. Prioritize quality over quantity. White hat SEO link building tactics that earn high-quality links include: original research other sites will cite, expert commentary for media and industry publications, guest posts on established industry blogs, and building tools or resources that naturally attract links.
Diversify Your Linking Root Domains
Unique referring domains are weighted more heavily than repeat links. If most of your links come from one or two domains, DA won’t grow proportionally with your link count. The priority is getting links from a growing number of distinct sites.
Build Natural Link Profiles
Moz’s model is trained to detect link patterns. A profile dominated by exact-match anchor text, links from irrelevant niches, or bulk directory submissions suppresses DA accuracy and can reduce the score even as raw link numbers grow. Natural links use varied anchor text, come from contextually relevant pages, and arrive at a pace that reflects genuine editorial discovery.
Eliminate Toxic Backlinks
Spammy links pointing to your domain drag down your link profile quality score. Use Moz’s Spam Score alongside Google’s Disavow Tool to identify and neutralize genuinely harmful links. Be conservative — disavowing legitimate links accidentally can hurt rankings.
Strengthen Internal Authority Distribution
External links entering your site at the homepage or top-level pages need to flow to deeper pages. Strategic internal linking ensures that DA earned at the domain level reaches your most important content. Use follow links for internal connections — nofollow internal links don’t pass authority.
Be Patient — The Logarithmic Scale Is Unforgiving
Moving from DA 10 to DA 20 can take 3–6 months of active link building. Moving from DA 40 to DA 50 might take 12–18 months. Moving from DA 60 to DA 70 is a multi-year effort. Set realistic timelines and measure progress quarterly, not weekly.
Domain Authority Misconceptions That Persist
“My DA dropped — something is wrong.” Not necessarily. Moz periodically recalibrates its entire DA model, which causes widespread score changes across all sites simultaneously. Your score can drop even while your actual backlink profile improved, simply because Moz recalibrated the scale. Check whether competitors also dropped before concluding there’s a problem.
“Ranking higher with a lower Moz score is impossible.” This query appeared in the GSC data because it’s a genuine confusion point. It is absolutely possible — and common — to rank above higher-DA competitors. DA is a domain-level metric. Individual page quality, content relevance, search intent alignment, local signals, and featured snippet optimization all operate independently of DA. A DA 30 page that perfectly answers a specific query can outrank a DA 60 page that answers it vaguely.
“DA is a Google ranking factor.” Covered above, but worth repeating because this query appeared explicitly in the GSC data: “domain authority is a moz metric not used by google ranking factor” — people are searching to confirm this. Google does not use Moz DA. Moz is a third-party company. DA is not in Google’s algorithm.
“A high DA means my site is healthy.” DA measures one specific thing: link profile strength as a ranking predictor. It doesn’t measure duplicate content, crawlability, page experience, or conversion performance. A site can hold DA 50 and have severe technical SEO problems simultaneously.
DA vs. Other Authority Metrics
Moz is not the only tool measuring domain authority. Different platforms use different methodologies and produce different scores:
| Tool | Metric Name | Scale | Primary Signal |
|---|---|---|---|
| Moz | Domain Authority (DA) | 1–100 | Link profile + MozRank/MozTrust |
| Ahrefs | Domain Rating (DR) | 0–100 | Referring domain count + quality |
| Semrush | Authority Score | 1–100 | Links + organic traffic + spam signals |
| Majestic | Trust Flow / Citation Flow | 0–100 each | Link trust proximity to seed sites |
None of these metrics are interchangeable — the same site will often have meaningfully different scores across tools. Use whichever tool your team is already using for consistency, and compare within the same tool when benchmarking competitors.
Tools for Checking Domain Authority
MozBar — Free Chrome extension. Shows DA and PA scores inline as you browse any website. The fastest way to check authority while doing competitive research.
Moz Link Explorer — Moz’s dedicated backlink analysis platform. Shows full link profiles, DA/PA scores, spam score, top linking domains, and anchor text distribution. Free tier allows limited lookups; paid plans unlock full access.
Moz’s Free DA Checker — Bulk DA check available at moz.com/domain-analysis for quick batch lookups without Link Explorer.
Third-party SEO platforms — Ahrefs, Semrush, and Ubersuggest surface Moz DA alongside their own metrics, allowing side-by-side authority comparison within a single tool.
Always use official Moz tools or verified integrations for DA data. Unofficial “DA checkers” may display cached, outdated, or fabricated scores.
Conclusion
Domain Authority is a useful benchmarking tool when you understand exactly what it measures and what it doesn’t. It’s Moz’s machine learning prediction of how well a site will rank, built almost entirely from link profile signals — linking root domains, MozRank, MozTrust, and link equity distribution. It is not a Google ranking factor, not a measure of content quality, and not a guarantee of anything in isolation.
The highest-value uses of DA are competitive benchmarking before targeting keywords, evaluating link opportunities, and tracking whether your link-building is gaining ground over time. The number itself matters far less than whether yours is trending up relative to competitors you’re trying to outrank.
Improving DA has no shortcuts. It requires earning high-quality links from diverse, authoritative domains through legitimate off-page SEO work — content worth linking to, relationships with publishers, and the kind of website authority that accumulates through consistent effort over 12–24+ months. Build that, and DA growth follows.
