Domain authority and page authority: what they mean for SEO

If you've read anything about SEO, you've probably seen domain authority mentioned. It's the number between 1 and 100 that supposedly predicts how well your site will rank. Many website owners obsess over it. Some teams check it daily. Others ignore it completely because they're confused about what it actually means.

Domain authority and page authority are metrics created by an SEO software company to predict how likely a website or web page is to rank well in search results. But here's the critical part: they are not Google ranking factors. Google doesn't use them to rank websites. They're estimates, useful signals for comparison—but not the direct reason your site ranks or doesn't rank.

Understanding what these metrics actually do, and what they don't, will save you from wasting effort on the wrong things.

What domain authority actually is

Domain authority (DA) is a score from 0 to 100, created by Moz (an SEO software company), that predicts how likely an entire domain is to rank well. It's calculated based on backlink data—how many backlinks your site has, how many different domains are linking to you, and the authority of those linking domains.

The score is logarithmic, meaning it gets harder to improve as you go higher. Moving from a score of 10 to 20 is easier than moving from 40 to 50. Moving from 70 to 80 requires significantly more backlinks from increasingly authoritative sites. This reflects reality: Google trusts established sites more than brand new ones.

A brand new website has a DA of 1. A well-established site in a competitive industry might have a DA of 50 or higher. The largest, most well-linked sites in the world have scores in the 80s and 90s (only a few major sites like Wikipedia and government sites hit the top).

What page authority actually is

Page authority (PA) is similar, but it measures a specific page rather than your entire domain. A single page on your site can have a PA of 30 while your domain has a DA of 20. This happens because that page received significant backlinks and internal links, building its own authority independent of your overall site strength.

The logic makes sense: a single piece of content can be incredibly useful and widely linked to, even if the overall site is new. A new blog might publish one article so useful and comprehensive that major websites link to it. That article gets a high PA even though the blog itself isn't established.

How domain authority and page authority work together

These metrics influence each other. A high domain authority helps all your pages rank better—it gives each page an authority boost just from being on your domain. Building backlinks to individual important pages increases their page authority, which over time raises your overall domain authority.

The relationship is symbiotic. If you're an established brand with high domain authority, a new page you publish will inherit some of that authority and likely rank faster. If you're a new site with low domain authority, you can still get a page to rank well by building specific links to that page to raise its page authority.

What domain and page authority actually predict

Moz did research showing that sites with higher domain authority tend to rank higher for competitive keywords. So the metric does correlate with rankings. But correlation isn't causation.

The metric predicts based on backlinks, but Google ranks based on many factors: content quality, user experience, page speed, mobile-friendliness, relevance, topical authority, and yes—backlinks. A site with high domain authority might not rank if its content is weak. A newer site with high-quality content and strategic links can outrank a site with higher domain authority but worse content.

The score is useful for benchmarking—"How does my domain authority compare to competitors in my industry?"—but it's not a direct ranking factor. You can't buy your way to a higher score, and obsessing over it can distract you from the real work of SEO.

Why so many marketers focus on domain authority

Domain authority gained traction because it's easy to understand and easy to measure. A number you can track, compare, improve. Marketing teams love metrics they can show to clients: "Your domain authority went from 15 to 22." It looks like progress.

Moz sells software that tracks these metrics, so there's incentive to make them feel important. And since the metric does correlate with rankings (for the reasons above), many SEO consultants use DA as a shorthand for "how well your site will rank."

But this has a side effect: it can make people chase the metric instead of chasing actual rankings. A business owner hires an SEO consultant who promises to improve their domain authority from 10 to 25 in six months. That consultant focuses on building backlinks (which is good), but maybe from less relevant sources just to improve the score. Meanwhile, pages that should rank well still don't because the content or internal linking structure isn't optimized.

What matters more: domain authority or content quality?

This is the real question, and the answer is: content quality, by a lot.

Google's algorithm weighs content quality heavily. A detailed, useful, original answer to a search query ranks better than a thin article on a high-authority domain. This is why new sites can rank against established competitors—the new site's content is better.

You need some domain authority (which means some backlinks) to be in the conversation for competitive keywords. But once you have a baseline—say, a few quality backlinks establishing that you exist and are relevant—content quality becomes the ranking differentiator.

A more honest ranking of what matters: great content beats good content from a higher-authority site. Good content from a high-authority site beats great content from a low-authority site. But the difference between good and great content is often bigger than the difference in domain authority between your site and a competitor's.

Domain authority for small businesses: should you care?

If you're a small business owner trying to rank for local keywords or niche topics, domain authority is less critical. You're competing against other businesses and generalist sites, not against established publishers. You can win on content quality, relevance, and local signals.

That said, understanding domain authority helps you make smarter decisions. If a competitor marketing agency has domain authority of 15 and your WEMASY site has domain authority of 8, and they're ranking for "digital marketing agency in [city]"—it's probably not the domain authority difference holding you back. It's more likely your content doesn't match their depth. Build better content and get a few backlinks to it, and you'll rank higher.

Track your domain authority if it interests you (it's visible in any SEO tool), but don't let it distract you. Your focus should be on ranking for the keywords that matter to your business. If your pages are ranking well, your domain authority score will follow. If they're not ranking, improving the DA score alone won't fix it.

How to improve your domain authority (if you choose to focus on it)

Domain authority improves as you get more backlinks from relevant, authoritative sites. So the tactics for building backlinks are also the tactics for improving domain authority. Create comprehensive guides, publish original research, do guest posting, build relationships with relevant sites, and earn coverage in your industry. These all build backlinks and raise your domain authority over time.

But here's the honest truth: if you build backlinks strategically to the pages that matter most for your business, your domain authority will improve naturally. You don't need to focus on the metric itself. Focus on building quality links to important pages, and let domain authority be a scorecard rather than a goal.

The metrics that matter more than domain authority

While domain authority gets attention, these metrics actually drive results:

Organic traffic to your site

How many visitors come from Google? This is what SEO actually accomplishes. A site with high domain authority but low organic traffic isn't working. A site with lower domain authority but growing organic traffic is winning.

Keyword rankings for your target keywords

Where does your page rank for the keyword you care about? If you want to rank for "affordable website builder," check your ranking for that specific phrase. That's the metric that matters. Many sites check domain authority and ignore the specific keywords that drive their business.

Conversion rate and customer acquisition cost

Does your organic traffic actually convert to customers? Is it cheaper to get a customer through organic search than through paid ads? This matters infinitely more than a domain authority number.

Domain authority vs. page authority: which should you focus on?

Focus on both, but in order. First, build page authority on your most important pages—the ones that drive revenue or matter most to your business. Target specific backlinks to those pages, write in-depth content, and optimize internal linking to them.

As individual pages get authority and rank well, your overall domain authority rises naturally. You end up with high domain authority plus high-ranking pages—not high domain authority and pages that still don't rank.

Many SEO strategies get this backward: they focus on boosting overall domain authority, then hope all pages benefit. The smarter approach: build authority on the pages that move the needle first. Your domain authority follows.
