What is Domain Authority?

Most marketing teams get completely tangled up with Domain Authority. They check it religiously but couldn’t explain what it measures if their jobs depended on it. Moz created this 1-100 scoring system to predict how well sites might rank. Higher numbers supposedly mean better chances. Here’s what catches everyone out though: Google has never used Domain Authority for anything. It’s just Moz’s educated guess, not some official ranking signal. Understanding this distinction matters if you want your SEO strategy to make sense.

How Domain Authority Gets Calculated

Behind the scenes, Moz throws 40+ signals into a machine learning system that’s been trained on real search results. Backlinks carry most of the weight here. How many different websites link to you matters, plus whether those linking sites have any clout themselves. One link from the BBC trumps dozens from random blogs that nobody’s heard of.

DA scores work on a logarithmic scale, which trips people up constantly. Going from 20 to 30? Pretty straightforward with some decent content and outreach. But pushing from 60 to 70 is brutal. Every single point becomes a slog because the low-hanging fruit disappears and quality publications start getting picky about who they’ll link to.

Don’t freak out when your DA bounces around for no obvious reason. Moz keeps updating their data and tweaking the algorithm, which means your score shifts relative to everyone else’s changes too. We’ve watched clients lose sleep over a five-point dip that had absolutely nothing to do with their website. Look at patterns over months, not daily fluctuations.

DA Isn’t the Only Authority Metric

Here’s where it gets messy. Moz kicked things off with Domain Authority, then Ahrefs and SEMrush decided they could do better with their own versions. Different calculations, different data sources, different names for what’s in practice the same idea.

Don’t expect the numbers to line up because they won’t. One site we checked recently scored DA 42, DR 56 and AS 35 all at once, which sounds contradictory but actually makes perfect sense. Each platform’s measuring something slightly different with proprietary datasets that overlap but don’t match exactly. Averaging these scores together? That’s just creating confusion where none needs to exist.

What Drives Your DA Score

Backlinks drive everything here, though the specifics get complicated:

• Linking root domains carry more weight than total links. Ten links from ten different websites beat fifty links from two. Google thinks the same way, which is partly why DA correlates loosely with rankings.
• Authority passes through links. A mention from an established industry publication moves the needle more than dozens of directory listings or blog comment links ever could.
• Relevance counts. Links from websites in adjacent industries or covering related topics signal genuine endorsement rather than random acquisition.
• Profile health affects the calculation. Sites with natural, steady link growth score better than those with obvious spikes from link schemes or sudden drops from lost partnerships.
• Domain age plays a quiet role. Established sites with years of consistent link building tend to score higher than newer domains, even with similar raw link counts.

Why B2B Teams Should Care About DA

B2B marketing teams actually find DA useful despite all its quirks.

Got three competitors sitting pretty at DA 55-60 while you’re languishing at 32? That’s boardroom gold right there. Try walking into a meeting and explaining why you need more “link equity” without any numbers to back it up. Good luck with that. DA hands you something concrete when you’re pushing for off-page SEO investment.

Why waste time chasing links from DA 15 sites when DA 50+ opportunities are sitting right there in your space?

Keyword rankings bounce around like a pinball machine. Algorithm tweaks, personalised results, competitors making moves, all creating noise that’s impossible to explain in quarterly reports. DA moves at glacial pace, which actually helps when you need to demonstrate sustained progress rather than justify why you dropped from position 4 to position 7 this month.

Domain Authority provides consistency that rankings can’t match. Where individual keyword positions fluctuate daily based on personalisation and algorithm changes, DA shifts slowly and predictably over quarters, making it ideal for executive reporting.

Where Domain Authority Falls Short

Agencies love chasing DA because it’s neat and measurable. Problem is, they get tunnel vision and completely ignore what it doesn’t tell you.

Worth repeating because people keep forgetting this. Google doesn’t use it. We’ve seen DA 35 sites absolutely demolish DA 60 competitors for commercial keywords that actually matter. Better content and solid on-page work beats higher scores every single time.

Think your DA 50 means every page will rank well? Think again. DA measures domains, not individual pages, which means your homepage might look impressive while product pages sink without a trace. Poor internal linking and thin content don’t register in domain metrics, but they’ll kill your rankings fast.

Here’s what DA completely ignores. Content quality, search intent matching, Core Web Vitals, mobile experience and E-E-A-T signals. Basically hundreds of factors that Google actually cares about when deciding who ranks first.

Private blog networks can pump up DA scores overnight without moving the needle on actual rankings. Some agencies love this trick because they get to show impressive DA improvements while organic traffic stays flat (or worse). Your DA went up 15 points but you’re still buried on page three? Time for some awkward conversations.

What’s a Good DA Score?

Your market dictates everything here. That DA of 38? Could be brilliant if you’re in a niche B2B sector where most competitors hover around 28. But stick that same score in a competitive space where the big players are sitting at 70+ and you’re basically invisible.

Between 30-50 covers most business websites. Starting from scratch means single digits and you’re looking at two or three years of solid work just to hit 30. Enterprise organisations? They’re often cruising past 70, while household names push toward 90+.

Want to check where you stand? Moz Link Explorer gives you free domain checks. Run your competitors through it and see what you’re up against. If they’re averaging DA 48 and you’re stuck at 31, that 17-point gap isn’t closing overnight (we’re talking 12-18 months of serious effort).

How to Improve DA

No shortcuts exist here and the tactics that actually move DA are exactly the same ones that build real authority.

Want links that actually matter? Build something worth linking to. Original research beats rehashed industry statistics every time. thorough guides that solve real problems become bookmarks. Thought leadership means taking a stance, not regurgitating what’s already been said a thousand times. Generic blog posts won’t earn editorial mentions no matter how polished the prose.

Target publications that make sense for your industry. Trade media loves linking to relevant expertise and industry associations often showcase member insights. Check where your competitors get their links using the Ahrefs backlink checker. Most sectors have three or four key publications that regularly link out.

Technical problems kill link equity faster than you’d think. Broken internal links create dead ends, redirect chains dilute authority and orphaned pages waste existing link value. A technical SEO audit usually uncovers simple fixes that help your existing links work harder.

Don’t rush to disavow links unless you’re certain they’re toxic. Google’s disavow tool works for obvious spam or deliberate negative SEO attacks, but removing borderline links often backfires. We’ve seen sites lose rankings after disavowing perfectly legitimate (if not stellar) backlinks.

Anyone promising DA improvements in under six months? They’re talking poor quality. Meaningful gains take 6-18 months minimum and that’s if you’re doing everything right with zero shortcuts.

Building Domain Authority isn’t about gaming the system. It’s about creating the kind of website that other sites naturally want to reference . one with authoritative content, technical excellence and genuine expertise in its field.

Using DA Without Overvaluing It

Check quarterly, never weekly (you’ll drive yourself mad). Compare against your actual competitors, not some random number you found online and use it for link prospecting decisions. Beyond that, it’s pretty limited.

Don’t rely on just one metric though. SEMrush’s domain overview or Ahrefs Domain Rating will show you different angles because each tool picks up different signals.

Here’s the thing about chasing DA directly. It leads to terrible decision-making and shortcuts that’ll bite you later. Build quality content, nurture real relationships and nail your technical foundations instead. The authority scores follow naturally when you focus on what actually matters.

We don’t chase numbers for the sake of it. Our approach focuses on building authority that actually moves the needle for your business, which means sustainable practices over quick wins. When we handle WordPress development, we’re thinking about internal linking architecture, page speed optimisation and the technical groundwork that’ll support your SEO efforts for years to come. Because honestly? The actual score is just a reflection of what really matters: creating sites that people want to link to and search engines trust.
