Domain Rating vs Domain Authority: DR vs DA, Explained Properly

Domain Rating vs domain authority comes down to who built it: Domain Rating (DR) is Ahrefs' 0 to 100 score of backlink strength alone, while Domain Authority (DA) is Moz's 0 to 100 score built from a machine-learning model. They almost never match for the same site, Google uses neither to rank you, and this guide shows which one to trust when you are actually judging a backlink prospect.

I wrote this because Search Console shows people landing on this site after searching domain rating vs domain authority, domain rating checker and free dr checker, all sitting between position 80 and 90 with real impressions and no page built to answer any of them. Below I explain how Ahrefs and Moz actually calculate their numbers, what counts as a solid score for an Indian business rather than a global publisher, and the specific checklist I use before deciding whether a backlink prospect is worth pursuing.

Domain Rating vs Domain Authority: the short answer

Domain Rating and Domain Authority answer a similar question with different math, and neither one is a Google ranking factor. DR comes from Ahrefs and looks only at your backlink profile: how many separate websites link to you and how strong those linking sites are. DA comes from Moz, explained fully in my domain authority guide, and layers a machine-learning model on top of comparable link data, trained to predict how often a domain shows up in real Google results.

Both run on a 0 to 100 logarithmic scale, which means the climb from 10 to 20 takes far less link-building effort than the climb from 60 to 70. Semrush publishes a third number, Authority Score, which I cover below since it adds a factor the other two skip entirely: real organic traffic.

The practical answer most people actually want is this: check DR first if you are prospecting backlinks, since Ahrefs runs one of the largest independent link indexes and DR updates continuously. Check DA as a second opinion, since Moz's scoring model was built specifically to correlate with Google rankings rather than raw link volume. Never expect the two numbers to match, and never trust either one on its own. The rest of this guide explains exactly why, and what to check instead.

How Ahrefs calculates Domain Rating

Ahrefs defines Domain Rating as the strength of a website's backlink profile compared to every other domain in its index, scored on a 100-point scale. The calculation runs on link equity: every domain passes a share of its own rating to the domains it links out to.

The mechanic that matters most for backlink prospecting is how that share gets split. A domain divides its rating equally among every domain it links to. A DR 10 site that links out to three other domains passes more influence to each of those three than a DR 80 site that links out to a million domains across its entire footprint. This is why a small, tightly curated resource page sometimes hands you more real benefit than a mention buried in a massive, link-heavy footer. Not every link participates in this split either; a nofollow link typically passes little or no Domain Rating even when it sends real referral traffic.

Ahrefs runs this calculation continuously as its crawler finds new links, rather than on a fixed monthly schedule, so DR for an actively linked-to domain can shift within days of a real link appearing. That continuous recrawl is also why DR sometimes looks more volatile than DA for a site that just earned or lost a handful of links.

How Moz calculates Domain Authority

Domain Authority also runs 0 to 100, but Moz builds it from six link-graph inputs fed into a machine-learning model rather than backlink data alone: linking root domains, MozRank, MozTrust, a Spam Score adjustment, anchor text distribution and total backlink volume. The model is trained to predict how likely a domain is to appear in Google's actual search results, then it gets retrained periodically as those results shift.

That training step is the real difference from DR. Ahrefs measures link strength directly. Moz asks a model to estimate ranking likelihood from link patterns, which means DA can move even when your raw backlink count barely changes, if the pattern of those links starts to resemble sites that already rank well. Two sites with a similar number of referring domains can also show noticeably different DA if one has a healthier anchor text mix or a lower Spam Score.

Moz's free Link Explorer gives ten lookups a month on any domain, competitors included, which makes it the easier of the two tools to use for spot-checking a prospect without a paid account. I use it as the second opinion after an Ahrefs DR check, not as my primary number, since Ahrefs' index tends to be larger for the kind of mid-sized Indian business sites I work with day to day.

Semrush Authority Score: the third number worth knowing

Semrush describes Authority Score as a compound metric built from backlink signals, estimated organic traffic and spam factors, also on a 0 to 100 scale. Folding in traffic is what sets it apart from DR and DA, both of which look at links alone.

That traffic component makes Authority Score useful as a tiebreaker. A site with a modest backlink profile but real, growing organic traffic can outscore a link-heavy site that gets almost no search visitors, which is exactly the pattern worth catching before pitching a guest post to a domain that looks strong on paper but is quietly dead in the search results. I do not lead with Authority Score, but I check it whenever DR and DA disagree sharply on the same prospect.

Why the same site shows three different numbers at once

Say a Pune based B2B manufacturer's site shows Ahrefs DR 38, Moz DA 24 and Semrush Authority Score 31 in the same week, purely as an illustration. All three readings can be correct at once, because each company is answering a slightly different question with data nobody else has access to.

Ahrefs and Moz maintain separate web crawlers that discover different links at different times, and neither company shares its index with the other or with Semrush. A backlink Ahrefs found last month might not appear in Moz's index for another six weeks, and a low-quality forum link Moz's spam filters flag might not register as a problem in Ahrefs' math at all. Update cadence widens the gap further: DR recalculates near-continuously as Ahrefs' crawler works, DA has historically moved on something closer to a monthly cycle, and Authority Score sits somewhere in between.

None of this means one score is wrong and the others are right. Compare DR against DR over time, and DA against DA, rather than asking why the two numbers do not match each other. The gap between your score and a competitor's, measured with the same tool, is the only comparison that actually means anything.

What counts as a good DR and a good DA for an Indian business

Both scores are logarithmic, so the honest answer depends on who you are being compared against, not a fixed number either company publishes. Treat the bands below as realistic working ranges rather than a formula, since neither Ahrefs nor Moz publishes an official definition of good.

For a small, single-location Indian business two to five years into consistent SEO work, DR 10 to 25 and DA 15 to 30 are both realistic and healthy. A regional player with genuine press coverage and a handful of strong industry backlinks can reasonably sit at DR 25 to 45 and DA 30 to 45. National publishers, large marketplaces and category-leading brands routinely show DR and DA above 70, a range built on years of organic press coverage that a single-location business has no practical reason to chase.

Do not treat DR and DA as interchangeable inside these bands either. A site can show DR 35 and DA 22 at the same time and still be perfectly healthy for its size, since the gap reflects each tool's own math rather than a problem with the site. Judge each number against competitors checked with that same tool, exactly as I cover in more depth in my domain trust score guide.

Free ways to check DR, DA and Authority Score

You do not need a paid subscription to get a first reading on any of the three. Ahrefs publishes a free public Website Authority Checker that returns DR for any domain with no login required, separate from Ahrefs Webmaster Tools, which needs you to verify ownership before it shows the fuller Site Explorer view of your own backlinks.

Moz's free Link Explorer gives ten lookups a month for any domain, competitor sites included, which makes it the simplest way to get a DA reading without an ownership check getting in the way. Semrush's free account includes a handful of Authority Score lookups a month through its own checker tool.

My own free Website Authority Checker uses Open PageRank rather than DR or DA, since Open PageRank is the only major score with no login and no monthly cap. I use it as a fast first pass on a long list of prospects, then run the shortlist through Ahrefs and Moz for the DR and DA reading that actually matters for a go or no-go call. For the full walkthrough across every tool mentioned here, see my how to check website authority guide, and for free tools beyond authority checking, my roundup of free SEO tools for small business.

Which one to trust when judging a backlink prospect

Here is the actual checklist I run before saying yes to a guest post, a directory listing or a partnership link. No single score decides the outcome. The combination does.

Step 1: Check DR and DA side by side, not one in isolation

Run the prospect's domain through Ahrefs' free checker for DR and Moz's Link Explorer for DA, and pair it with a free Website SEO Checker run so a weak on-page setup does not slip past you too. A site that scores reasonably on both authority metrics is a safer bet than one that scores high on only one, since that gap often means an unusually skewed link pattern.

Step 2: Check the specific page that will link to you, not just the domain

A DR 60 domain with your link buried three folders deep on a page Google has never bothered to index passes you nothing. Search for the exact page URL in Google to confirm it is indexed, and check whether that page carries any referring domains of its own using the same free tools.

Step 3: Check Spam Score and outbound link count for dilution risk

Pull Moz's Spam Score for the domain, and count how many external links sit on the actual page that would carry yours. Remember Ahrefs' own math: a domain that links out to hundreds of sites on one page splits its rating that many ways, so your real share of a DR 50 site's authority can end up smaller than a clean mention on a DR 20 site that rarely links out.

Step 4: Check topical relevance and real organic traffic

Cross-check Semrush's Authority Score or a free traffic estimate to confirm the site gets genuine search visitors, not just backlinks pointing at an otherwise dead property. A relevant local or industry site with modest DR and real traffic is usually worth more than an unrelated high-DR site that exists mainly to sell links.

Step 5: Make the call and log the decision

Set a simple rule before you get pitched, for example: proceed if DR and DA both clear your minimum band for the category, the linking page is indexed, Spam Score is low and the topic is relevant. Log every prospect and outcome in a sheet so next quarter's decisions get faster and more consistent than this quarter's, the same habit behind my SEO KPIs to track guide.

Common mistakes when comparing DR and DA

Panicking over a gap between the two scores. A site showing DR 40 and DA 22 has not necessarily lost authority somewhere; the two tools are measuring related but different things with different data. Track each one against itself over time instead of expecting them to converge.

Rejecting a prospect on domain score alone. A relevant, real page on a modest domain regularly outperforms an irrelevant mention on an impressive one, the same page-level lesson I cover in page authority vs domain authority. Check the linking page before you check the domain.

Paying for links to move either number fast. A sudden cluster of low-quality links can nudge DR or DA up for a few weeks before the next significant recrawl catches the pattern and the score corrects back down, often alongside a manual action risk that costs far more than the link was worth. Real, earned links from relevant sites remain the only durable way to move either score, the same approach behind my small business backlink guide.

Treating a lookalike checker's teaser number as the real one. Several third-party sites show a rough DR-style estimate without ever pulling real Ahrefs data behind it. When a number matters for a real decision, check it on the tool that actually owns the metric, not an imitation.

The honest bottom line: Google uses neither

Ahrefs states plainly that there is no evidence search engines use Domain Rating, Domain Authority or any similar score as a ranking factor. Google's own John Mueller has said much the same thing directly: Google does not evaluate a site's authority and does not hand out a score for it.

That does not make either metric useless. It just means you should use them for what they actually measure. DR and DA correlate with rankings because the underlying signal, real websites choosing to link to you, is something Google's own systems do care about. The score is a proxy for that signal, not the signal itself, and definitely not something anyone at Google looks up before ranking your page.

Use DR to size up a backlink prospect quickly. Use DA as your second opinion. Use Authority Score to catch a site that looks strong but gets no traffic. Then get back to the off-page SEO work that actually moves all three at once: earning links from real, relevant sites your customers already trust.

Frequently asked questions

What is a good domain rating?

There is no fixed good number because Domain Rating is logarithmic and relative to whoever you compete with. For a small, single-location Indian business a few years into consistent SEO work, DR 10 to 25 is realistic and healthy. A regional player with genuine press coverage can reasonably sit at DR 25 to 45. National publishers and large marketplaces routinely show DR above 70, a range built from years of organic press that most small businesses have no practical reason to chase.

Is DR or DA more accurate for judging a website?

Neither is more accurate because they measure related but different things: DR looks purely at backlink data, while DA adds a machine-learning layer trained to correlate with Google rankings. Ahrefs generally crawls a larger link index, which makes DR useful as a first check, while Moz's free Link Explorer makes DA easy to pull as a second opinion. Use both together rather than picking one as the definitive number.

How do I check domain rating for free?

Ahrefs publishes a free public Website Authority Checker that returns Domain Rating for any domain with no login required, separate from Ahrefs Webmaster Tools, which needs site ownership verification for its fuller backlink reports. Paste the bare domain and read the score in a few seconds. Check your own domain and a handful of competitors or prospects the same way so the number has something to compare against.

Why do Ahrefs and Moz show different scores for the same website?

Because the two companies run separate web crawlers that discover different backlinks at different times, use different formulas to weigh link quality, and update on different schedules. Ahrefs recalculates Domain Rating near-continuously, while Domain Authority has historically moved on something closer to a monthly cycle. A site can show DR 38 and DA 24 at the same time and both readings can be correct by each tool's own logic.

Does a high DR or DA guarantee good Google rankings?

No. Ahrefs itself states there is no evidence search engines use Domain Rating or Domain Authority as a ranking factor, and Google's John Mueller has said directly that Google does not evaluate a site's authority or hand out a score for it. Both metrics correlate with rankings because they track real backlinks, a signal Google does value, but a page that matches search intent poorly can still underperform regardless of how high its domain score reads.
