Domain authority isn’t a Google ranking factor - Google has said this explicitly. But it correlates strongly with rankings because the things that increase domain authority (quality backlinks from diverse sources) are the same things Google’s algorithm rewards.
Whether you use Ahrefs’ Domain Rating (DR), Moz’s Domain Authority (DA), or Semrush’s Authority Score (AS), the underlying principle is the same: websites with more high-quality backlinks from more unique referring domains tend to rank better.
Here’s how to systematically improve yours.
Understand What You’re Measuring
Domain Rating (Ahrefs), Domain Authority (Moz), and Authority Score (Semrush) all measure slightly different things, but they share a common core: the quantity and quality of external websites linking to your domain.
A few important nuances:
It’s logarithmic. Going from DR 10 to 20 is much easier than going from 60 to 70. Each point becomes exponentially harder to earn. A brand new website might reach DR 20-30 within a few months of active link building. Getting above DR 50 typically takes years of sustained effort.
Referring domains matter more than total backlinks. 100 links from 100 different websites is far more valuable than 100 links from the same website. Diversity of linking domains is the primary driver of domain authority scores.
Quality compounds over time. A backlink from a DR 70 website passes more authority than one from a DR 20 website. But even modest links from legitimate, relevant websites accumulate value over months and years.
The Backlink Building Stack
Think of link building as a stack, from foundational to advanced:
Foundation: Directory and Citation Links
Every website’s backlink profile starts with directory listings. These are the easiest links to acquire and they establish your site’s presence in Google’s link graph.
Free directories with nofollow links: Google Business Profile, Yelp, Bing Places, Yellow Pages, BBB. These don’t directly boost domain authority (nofollow), but they establish NAP consistency and brand presence.
Paid directories with dofollow links: A smaller category, but significantly more impactful for domain authority. Directories that require payment or verification before providing dofollow links are moderated by design - which means Google is more likely to trust links from them. Bunity, for example, provides dofollow links on claimed listings for a $3 one-time fee across 190+ countries.
Niche and industry directories: Trade associations, professional organizations, and industry-specific directories. These carry strong topical relevance and are often high-authority domains themselves.
A solid foundation might include 15-25 directory listings, with 5-10 of those being dofollow. This alone can get a new website to DR 15-25.
Mid-Tier: Content-Driven Links
Once your foundation is set, the next layer is earning links through content that other websites want to reference:
Original research and data. If you can publish unique data - survey results, industry benchmarks, trend analyses - other sites will cite you as a source. A single well-promoted data study can generate 20-50 referring domains.
Comprehensive guides. The “definitive guide to X” format works because writers researching a topic look for authoritative sources to link to. If your guide is genuinely the most thorough resource on a topic, it earns links passively over time.
Tools and calculators. Free tools that solve a specific problem (mortgage calculators, ROI estimators, SEO audit tools) earn backlinks because people link to useful resources.
Advanced: Relationship-Driven Links
The highest-quality backlinks come from relationships:
Guest posting on relevant industry publications. Not the spammy “submit a guest post” sites - real publications where your expertise adds value to their audience.
Digital PR. Getting quoted in news articles, interviewed on podcasts, or featured in industry roundups. These typically come from DR 60-90 domains and move the needle significantly.
Partnership and co-marketing links. Joint webinars, co-authored research, or integration partnerships with complementary businesses. These create natural linking opportunities between relevant sites.
What NOT to Do
Don’t buy links from link farms. Google’s algorithm has become remarkably good at detecting paid link schemes. A penalty from a link spam manual action can wipe out years of SEO work.
Don’t chase DA/DR obsessively. Domain authority is a proxy metric, not the goal itself. A DR 40 website that ranks on page 1 for profitable keywords is worth more than a DR 60 website with no conversions.
Don’t ignore link velocity. Going from 10 referring domains to 500 in a single month looks unnatural. Steady, consistent link acquisition over time is both safer and more sustainable.
Don’t neglect internal linking. External backlinks build domain authority, but internal links distribute that authority to the pages you want to rank. A strong internal linking structure multiplies the value of every external link you earn.
Measuring Progress
Track these metrics monthly:
Referring domains (unique). This is the single most important number. Are you gaining more unique linking domains each month? Even 5-10 new referring domains per month represents healthy growth for most businesses.
Domain Rating / Domain Authority. Track the trend, not daily fluctuations. A 1-2 point increase per quarter is solid progress.
Organic traffic. The ultimate measure of whether your link building is working. Domain authority improvements should translate into ranking improvements, which should translate into traffic.
Link acquisition rate. How many new backlinks are you earning per month? Is the rate increasing, stable, or declining? A declining rate means your content and outreach efforts need refreshing.
A Realistic Timeline
For a new website starting from zero:
Months 1-3: Foundation building. Directory submissions, social profiles, initial content. Expected DR: 10-20.
Months 3-6: Content-driven link acquisition. Publishing guides, tools, and data. Guest posting. Expected DR: 20-30.
Months 6-12: Relationship building and digital PR. Consistent content publication, outreach to industry publications, partnership development. Expected DR: 30-40.
Year 2+: Compounding growth. Passive link acquisition from existing content, ongoing PR, expanded content portfolio. DR 40+ is achievable but requires sustained effort.
These timelines assume active link building. A website that publishes content but does no outreach or link building will grow much more slowly - primarily through organic link acquisition, which depends on content quality and luck.
The Bottom Line
Improving domain authority isn’t a single action - it’s a sustained strategy of building diverse, high-quality backlinks from relevant sources. Start with the foundation (directory and citation links), build the mid-tier (content that earns links), and develop the advanced layer (relationship-driven links) over time.
The businesses that win at SEO aren’t the ones that find a single shortcut. They’re the ones that consistently build their backlink profile across all three layers, month after month.
