Domain Authority Checker — check DA & PA from a trusted provider
The Domain Authority Checker reports the Domain Authority (DA) and Page Authority (PA) of any website so you can benchmark your off-page SEO against your competitors. Both figures are third-party metrics created by Moz, and our DA checker surfaces them directly from a connected Moz integration. That means the number you see is the number the provider reports — we never invent, estimate or guess it. When no provider is connected, the tool shows “insufficient evidence” instead of a fabricated score, so you can always trust what appears.
What is a Domain Authority checker?
A domain authority checker is a tool that looks up how “strong” a domain is judged to be in search, expressed as a single comparative score. Rather than measuring your site in isolation, DA estimates how well a domain is likely to rank relative to other domains. Our checker retrieves the DA and PA values Moz has calculated and presents them clearly, alongside the context you need to interpret them responsibly — because a score without context can easily be misread.
What are Domain Authority (DA) and Page Authority (PA)?
Domain Authority and Page Authority are proprietary metrics developed by Moz. DA predicts how likely an entire domain is to rank in search results, while PA predicts the ranking strength of an individual page. Both are modelled primarily on a site’s link profile and are designed to be used for comparison — for example, weighing your site against a competitor, or one page against another. Because they are Moz’s own metrics, the only accurate source for Moz DA and PA is Moz itself.
The 1–100 logarithmic scale
DA and PA are scored on a 1–100 scale, and that scale is logarithmic. Moving from 20 to 30 is far easier than moving from 70 to 80, because the higher you climb, the harder each additional point becomes. This is why DA should be read as a comparative, third-party estimate and not as a precise measurement — and certainly not as a Google ranking factor. It is a useful yardstick for competitive benchmarking, nothing more.
How is Domain Authority influenced?
DA is driven overwhelmingly by your off-page SEO — specifically the quantity and quality of the links pointing to your site. The main inputs are:
- Backlinks. The total volume of inbound links your domain has earned across the web.
- Referring domains. The number of unique websites linking to you — usually more meaningful than raw backlink count, since many links from one site count for less.
- Link quality. Links from relevant, trusted, authoritative sites carry far more weight than links from spammy, low-quality or irrelevant sources.
Because these are the same signals that shape real search authority, DA moves in step with genuine link-building progress — though it typically updates slowly and in periodic recalculations by the provider.
How to improve your Domain Authority
You cannot “edit” your DA directly; you improve it by improving the underlying signals. The most reliable ways to raise Moz DA over time are:
- Create genuinely link-worthy content — original research, guides and resources that other sites want to reference.
- Earn links from relevant, high-authority sites through outreach, digital PR and partnerships.
- Grow your unique referring domains rather than chasing many links from the same few sites.
- Audit and clean up toxic links, disavowing spammy backlinks that could drag on your profile.
- Keep technical and on-page SEO healthy so the authority you earn is not wasted on a broken or slow site.
Why we source DA from a provider and never fabricate it
Domain Authority and Page Authority belong to Moz — they are computed with Moz’s own link index and model. There is no honest way to “calculate” a Moz score without Moz. For that reason, our DA checker only reports figures pulled from a connected Moz integration. If that integration is not configured, we deliberately show “insufficient evidence” instead of a made-up number. An estimated or guessed DA would be worse than useless: it would give you false confidence in a decision. Everything this tool displays is traceable to the named provider, or it is not displayed at all.
Domain Authority best-practices checklist
- Use DA and PA as comparative benchmarks, always against your real competitors.
- Track the trend over time, not a single snapshot — one reading tells you little.
- Prioritise referring domains and link quality over raw backlink counts.
- Pair your DA data with a Backlink Checker review to see the links behind the score.
- Never present a DA number as a Google ranking or a promised outcome.
- Only trust DA/PA figures that come from the connected provider; treat “insufficient evidence” as a valid, honest result.
Common misconceptions about Domain Authority
- “DA is a Google ranking factor.” It is not — DA is a Moz metric, and Google does not use it.
- “A higher DA guarantees more traffic.” DA predicts relative ranking potential; it does not guarantee rankings, clicks or conversions.
- “I should hit a specific DA number.” There is no universal target; what matters is how you compare within your niche.
- “Any tool can calculate my DA.” Only Moz can, because DA is Moz’s proprietary metric — anything else is an approximation at best.
- “DA changes instantly when I get a link.” It updates on the provider’s periodic recalculation, not in real time.

Frequently asked questions
What is a domain authority checker?
A domain authority checker is an SEO tool that reports the Domain Authority (DA) and Page Authority (PA) of a website. These are third-party scores created by Moz that estimate, on a 1–100 scale, how likely a site or page is to rank in search results relative to others. Our DA checker reads these figures from a connected Moz integration and displays exactly what the provider returns — it never invents or estimates a number.
Is Domain Authority a Google ranking factor?
No. Domain Authority is a metric created by Moz, not by Google. Google does not use DA in its ranking algorithm and has confirmed it does not have an internal "domain authority" score of this kind. DA is a useful comparative estimate for benchmarking your off-page SEO against competitors, but a higher DA does not directly cause higher Google rankings.
Where does the DA and PA data come from?
Domain Authority and Page Authority are proprietary Moz metrics, so accurate figures can only come from Moz. Our tool sources DA and PA from a connected Moz integration. When no provider is connected, we show "insufficient evidence" rather than a guessed value, because fabricating a third-party score would be misleading.
How can I improve my Domain Authority?
Because DA is largely driven by your backlink profile, you improve it the same way you earn genuine authority: publish content worth linking to, earn links from relevant high-quality sites, grow the number of unique referring domains, remove or disavow toxic links, and keep your technical SEO healthy. DA tends to move slowly, so focus on sustainable off-page SEO rather than quick wins.
What is a good Domain Authority score?
There is no universal "good" DA — it is comparative and depends on your niche and competitors. A new site may sit in the single digits, established brands often score 40–60, and major authoritative sites reach 80+. The useful comparison is against the sites you compete with in search, not an absolute target. Never treat a specific DA number as a guarantee of rankings or traffic.
