Domain Authority (DA) is a 1–100 score, created by Moz, that predicts how well a website can rank in search results based on its backlink profile. Page Authority (PA) is the same idea for a single page. You can check any site's DA free using Moz's Link Explorer, browser extensions, or by requesting your real numbers from us above. A "good" DA is relative to your niche, but DA 40+ is the credibility threshold for most businesses. To increase your DA, earn quality backlinks from diverse, trusted domains and keep your spam score low — or use BoostMyDA's done-for-you service to reach DA 40+ in 14–21 days.
There's no single "official" free DA lookup anymore — Moz limits free checks — so here are the three reliable ways to find any site's Domain Authority.
Moz's own tool gives the original DA, PA and spam score. A free Moz account includes a limited number of checks each month. Visit Moz Link Explorer.
Tools like MozBar or Ahrefs' toolbar show authority scores right in your browser as you visit any site — handy for quick competitor checks.
Enter your URL in the box above and we'll send your exact Moz DA, PA and spam score on WhatsApp, plus an honest read on your gap to DA 40+. No signup.
Other reputable tools with their own authority metrics include Ahrefs (Domain Rating) and Semrush (Authority Score). Each calculates authority a little differently, so scores vary between tools — that's normal.
If you'd rather check yourself, here are the most reliable free Domain Authority and Page Authority checkers — what each is best for, and the catch with each. Most "free DA" tools pull their number from Moz's data behind the scenes.
The original DA and PA, straight from the source — plus spam score and top linking domains. The most trusted number, since every other "DA" tool ultimately traces back to Moz's data.
Shows Ahrefs' own Domain Rating (DR) instantly with no account. The only major tool offering genuinely unlimited free checks, though DR is a different metric from Moz DA.
Semrush's Authority Score blends backlinks with traffic and spam signals. Backlinko's free, no-login checker pulls from the Semrush index — handy for a traffic-aware view.
Neil Patel's tool shows a link-based Domain Score plus traffic and keyword data in plain language. The friendliest option for beginners and small projects.
Check several URLs at once with no login. It pulls directly from Moz's data, so the number you see is Moz's DA, surfaced in a simpler interface.
Instead of one DA number, Majestic splits link quality (Trust Flow) from link quantity (Citation Flow). The TF/CF ratio reveals whether a profile is genuinely trustworthy or just large.

Important: DA (Moz), DR (Ahrefs) and Authority Score (Semrush) are separate metrics — a site at DA 42 on Moz might show DR 58 on Ahrefs. Both are correct; they're just different estimates of the same idea. Pick one tool and track it consistently against the same competitors each month.
"Good" depends on your niche and competitors, but this is the general scale the industry uses. Rather than chasing a number, compare your DA against the sites you're directly competing with.
| DA Range | Rating | Typical site type | What it means for you |
|---|---|---|---|
| 0–20 | Poor | New or very small sites | Little authority yet — needs link building. |
| 20–40 | Below average | Young blogs, local businesses | Building, but most niches need more. |
| 40–60 | Solid | Established businesses & blogs | Credible and competitive — the sweet spot. |
| 60–80 | Good | Recognised brands, strong publishers | Strong authority in competitive niches. |
| 80–100 | Excellent | Major authorities (Wikipedia, news) | Among the most trusted sites online. |
Tip: a brand-new site usually sits between DA 10–20 — that's completely normal. What matters is steady growth over time, not the starting number.
A 1–100 score from Moz predicting how well an entire domain can rank, based mainly on its backlink profile, unique referring domains, and spam score. It uses a logarithmic scale — moving from DA 20 to 30 is far easier than 70 to 80.
The same concept applied to a single page rather than the whole site. Your homepage often has higher PA than a brand-new blog post on the same domain.
Ahrefs' equivalent metric, scored 0–100 based purely on backlinks. Semrush has its own "Authority Score" that also factors in traffic and spam signals. Because each tool uses a different index and formula, the same site can score differently on each — so always compare like-for-like.
No — DA is a Moz metric, not used directly by Google. But the quality backlinks that raise DA are exactly the signals that do influence real Google rankings, which is why a higher DA usually correlates with better visibility.
Moz weighs several link-based signals together. These are the factors that move your DA up — or drag it down.
The number of links pointing to you, weighted heavily by how trusted and relevant the linking sites are.
Links from many different domains count for more than many links from a single site. Diversity signals natural authority.
Toxic or low-quality links raise your Moz spam score and pull DA down. A clean profile protects both DA and rankings.
A lot of bad advice circulates about DA. Here's what's true and what isn't, so you don't waste money chasing the wrong thing.
Want your score higher? These are the levers that actually move DA — and where most DIY efforts stall.
The single biggest driver. Aim for links from real, indexed, high-authority sites relevant to your niche — guest posts, digital PR, resource pages and genuine mentions.
Many unique linking domains beat a pile of links from one place. A varied, natural-looking profile is what Moz rewards.
Audit your backlinks (Google Search Console helps) and disavow spammy ones. Toxic links can lower DA and even trigger Google penalties.
Solid on-page SEO and sensible internal linking help Moz and Google crawl and value your pages — supporting authority over time.
Doing it yourself typically takes 6–12 months of consistent effort. If you need authority faster, that's exactly what we do.
Use Moz's Link Explorer (limited free checks with an account), a browser extension like MozBar, or simply enter your URL above and we'll send your exact Moz DA and PA on WhatsApp — free.
Because DA (Moz), DR (Ahrefs) and Authority Score (Semrush) are separate metrics from different companies, each with its own backlink index and formula. The same site can score differently on each — that's expected. For the original DA, use Moz's number.
Generally: 0–20 poor, 20–40 below average, 40–60 solid, 60–80 good, 80–100 excellent. For most businesses, DA 40+ is the credibility threshold. Always compare against your direct competitors rather than chasing an absolute number.
No. DA is a Moz metric, not used directly by Google. But the backlink signals that raise DA do influence real rankings, so a higher DA usually goes hand-in-hand with stronger organic visibility.
DA measures the authority of your whole domain; PA measures a single page. Both run on a 1–100 scale and are based on backlink data.
Earn quality backlinks from diverse, trusted domains, clean up toxic links, and strengthen on-page SEO. DIY usually takes 6–12 months. BoostMyDA does it for you — DA 40+ in 14–21 days, or a full refund.
Moz recalculates DA roughly monthly as it refreshes its link index. Small fluctuations between updates are normal across the whole industry.
Most free checkers are accurate because they pull the number directly from Moz's data — so you're seeing Moz's real DA in a simpler interface. The exceptions are tools showing a different metric (like Ahrefs DR or Semrush Authority Score), which are accurate but measure authority their own way.
A brand-new site usually starts around DA 1, climbing to roughly DA 10–20 in its first year as it earns links. That's completely normal — focus on steady growth rather than the starting number.
Yes. DA can drop if you lose high-quality backlinks, your spam score rises from toxic links, competitors gain stronger profiles, or Moz updates its algorithm. A backlink audit usually reveals the cause.
Doing it yourself through organic link building typically takes 6–12 months. With a focused white-hat campaign like BoostMyDA's, most sites reach DA 40+ in 14–21 days — or you get a full refund.
Both matter. DA reflects your whole site's strength, while PA tells you how well a specific page can rank. For commercial or landing pages you care about, a strong PA is just as important as overall DA.
BoostMyDA increases your Moz Domain Authority to 40+ in 14–21 days with safe, white-hat backlinks — or your money back.
