DR vs DA: which metric should you actually trust?

DR vs DA — the short answer

Both DR (Domain Rating) and DA (Domain Authority) are scores out of 100 that estimate how strong a website is, based largely on its backlink profile. They look almost identical. They are not the same.

The single most important thing to understand: neither is a Google metric. Google has its own internal authority models (we know this from leaked documentation), but it has never published anything called DR or DA. These two scores are invented by SEO tool vendors — Ahrefs and Moz respectively — as best-effort estimates of authority. Every SEO backlinks agency will quote you one or the other when describing the placements they're selling. They're useful proxies, not gospel.

The 10-second comparison

Both scores are logarithmic, which is a detail most clients miss. Going from DR 30 to DR 40 is roughly the same effort as going from DR 20 to DR 30 — it sounds like a small jump but represents a 10x leap in backlink quality and quantity. Going from DR 80 to DR 90 takes years of sustained editorial PR, which is why even category-leading brands top out around DR 75–85.

How DR is calculated (Ahrefs)

Domain Rating looks at how many unique referring domains link to your site, weighted by the DR of those linking domains. It's a recursive calculation: a link from a DR 90 site is worth far more than a link from a DR 20 site, because the DR 90 site itself has been validated by other DR 80+ sites linking to it.

Crucially, DR only considers backlinks. It doesn't care about your traffic, your content, your technical SEO, or anything else. It's a pure backlink-profile score — and that's both its strength (clean signal, no contamination from other factors) and its weakness (easier to manipulate by buying or building bad backlinks at scale).

DR also responds fast. Ahrefs updates its index continuously and recalculates DR daily, which means a successful PR campaign showing up in Ahrefs on Tuesday will already be reflected in your DR number by Wednesday. That feedback loop is one of the reasons most working SEO agencies have settled on DR as their default metric.

How DA is calculated (Moz)

Domain Authority uses backlinks as its primary input but also factors in 40+ other signals — though Moz has never publicly disclosed what they all are. The most-discussed contenders are spam score, MozRank distribution, on-page signal estimation, and historical link velocity. The opacity is part of why DA is regarded as slightly more "stable" than DR — it's harder to game when you don't know exactly what you're gaming.

DA also tends to be slower to react to new backlinks because of the monthly update cycle. A win in March might not show up in your DA number until late April, which makes it less useful for short-feedback-loop campaign work.

One more thing worth knowing: DA tends to be slightly more conservative than DR. Most sites have a higher DR than DA — a site with DR 70 might be DA 55. They're calibrated differently. If an agency quotes you a DA 60 placement, that's roughly equivalent to DR 70–75 on the same site. Always ask which metric an agency is quoting before you compare numbers between vendors.

Which one should you trust?

For most use cases in 2026: DR (Ahrefs). Three reasons:

1. Largest data set. Ahrefs has the largest live backlink index of any commercial tool, by some distance. More data behind the score means more accurate authority estimates, particularly for newer sites and for niches that DA's older index hasn't fully caught up with.
2. Faster updates. Daily updates mean you see new backlinks reflected fast. If you're running a PR campaign and want to know whether last week's placements have moved the needle, you can check on Wednesday and see the answer. With DA you're waiting until next month's recalculation.
3. Industry default. When other agencies quote authority scores, they almost always mean DR. When you read SEO trade press or industry research, the numbers cited are almost always DR. Standardising on the same metric as everyone else makes comparison easier.

That said, both metrics are directionally useful. A site with DR 92 / DA 85 is a tier-1 publication. A site with DR 12 / DA 8 is a brand-new blog. Anywhere in between, the two metrics are usually within ±15 points of each other and both will lead you to roughly the same ranking decision. For most everyday placement decisions, either score will do — what matters far more is what you cross-check it against.

How SEO backlinks agencies game DR and DA — and how to spot it

Because DR and DA are public, gameable metrics, an entire industry has grown up around inflating them artificially. The economics are simple: a £600 PR-style editorial SEO backlink requires hours of journalist outreach. A £80 manipulated-DR placement requires a couple of clicks on an inventory dashboard. Cheap link sellers compete on price, which means competing on pretending the cheap link is the same as the expensive one. Here's what to watch for.

"DR 90+ from £200" offers

The fastest-spotting red flag in the industry. Real DR 90+ backlinks cost £600–£1,200 because the underlying outreach work to a tier-1 journalist is expensive and slow.

If a vendor is advertising DR 90+ placements at £200, the link almost certainly comes from a PBN where DR has been pumped up by interlinking other PBN sites in a closed network. The DR number is real in Ahrefs; the underlying authority is fake; Google's models discount it heavily. You're paying for a metric, not a ranking impact.

Sites with high DR but no organic traffic

The single most reliable test we know. Pull the prospective linking site's organic traffic in Ahrefs or Semrush. Real publications have organic traffic proportional to their DR — a DR 75 niche industry publication should be doing 30,000–200,000 monthly organic visits, depending on niche.

If a site has DR 75 but only 200 monthly organic visits, the DR was almost certainly manipulated. Real readers + real DR is the unfakeable combination. Manipulated DR alone is cheap to fabricate.

Sites with high DR but mostly outbound links

Visual inspection catches this in 30 seconds. Open the site. Look at three or four recent articles. If every other article is a "guest post" linking out to commercial sites in unrelated industries — fintech, gambling, supplements, payday loans — you're looking at a link-selling site, not a publication.

Real publications have far more inbound editorial signal than outbound. Manipulated sites are the reverse. Spending 30 seconds on the site itself is faster than any tool.

Sudden DR spikes in the linking site's history

Ahrefs shows historical DR over time. A real publication's DR climbs gradually — a few points per year, with occasional bumps from major news cycles. A manipulated site's DR often shows a vertical spike at one point in time, where someone built or bought a network of sites and pointed them all at each other inside the same quarter.

You don't have to be a forensic SEO to spot this. The DR-over-time graph in Ahrefs makes it visually obvious — natural growth looks like a stairway, manipulation looks like a cliff.

What scores you should actually be targeting

For most commercial campaigns in 2026, here's the rough tier framework worth keeping in mind:

• Tier 1: DR 80+ — major publications. Forbes (DR 95), BBC (DR 95), Daily Mail (DR 94), The Guardian (DR 93), Bloomberg (DR 92), Reuters (DR 92). Hardest to win, biggest impact per placement, strongest brand-trust signal. Anyone Googling your company name will see "as featured in" snippets.
• Tier 2: DR 60–80 — established niche publications and respected industry blogs. Sweet spot for most clients on cost-per-impact. Examples vary by category but expect to see verticals like Forbes Advisor, MoneyWeek, Drapers, The Drum, Marketing Week sitting here.
• Tier 3: DR 40–60 — smaller niche blogs with real traffic. Useful for breadth, topical relevance, and natural-looking link velocity. The "everyone else in your category writes about you" layer.
• Below DR 40 — generally only worth pursuing if topically perfect for your niche AND has real traffic. Otherwise skip — the placement won't move rankings and the time cost isn't justified.

A healthy backlink profile is a mix across tiers — typically 20% tier-1, 50% tier-2, 30% tier-3. Pure tier-1 looks unnatural to Google's spam classifiers; pure tier-3 doesn't move the needle. Both extremes are red flags in different directions.

How we use DR and DA on every SEO backlink we deliver

Quick brand aside on how this shapes the work we deliver:

• We quote DR, not DA — by default, on every campaign report, every shortlist, and every monthly update. If a client asks for DA we'll provide it, but DR is the metric our team uses internally because it's what the rest of the industry has standardised on.
• Every prospective SEO backlink is verified on three dimensions — DR, real organic traffic, and content quality of the publication. A site has to pass all three checks before it goes on a target list. Roughly 40% of "high-DR" sites we get pitched by re-sellers fail one of those three checks; they don't make it onto our inventory.
• We don't sell tier mix as a black box — every campaign brief specifies the target DR distribution explicitly. If we're promising 5 placements at DR 70+ and 3 at DR 50–70, that's what's in the contract, and that's what's in the report.
• Every placement comes with a 12-month link guarantee. If a link drops, breaks, or gets switched to nofollow during the first year, we replace it free. The DR-verification work isn't worth much if the link disappears six months in — the guarantee is what makes it stick.
• DR is not the only thing that matters — for niche commercial categories, a DR 45 site with the right topical relevance and real traffic can outperform a DR 75 generalist publication. We'd rather take the right link than the highest-DR link.

If you're trying to evaluate an agency's pitch and want a sanity check on the DR/DA numbers they're claiming, contact us — we're happy to run their inventory through our verification process and tell you which placements we'd take, which we'd reject, and why.

The 30-second summary

• DR (Ahrefs) and DA (Moz) are competing scores out of 100 estimating site authority based largely on backlink profile.
• Neither is a Google metric — both are best-effort proxies. Useful, not gospel.
• For most use cases, trust DR — largest data set, daily updates, industry-standard metric.
• Always cross-check DR against real organic traffic. High DR + low traffic = manipulated. The two should be proportional.
• Watch for the four manipulation patterns: implausibly cheap "high-DR" offers, sites with no traffic, sites that are mostly outbound guest posts, and sudden vertical DR spikes in historical graphs.
• Healthy campaigns mix DR 80+, 60–80, and 40–60 placements at roughly 20/50/30. Pure tier-1 looks unnatural; pure tier-3 doesn't move rankings.
