You want your website to rank. You need traffic. You’re tired of watching competitors crush it on Google while your content sits on page three collecting dust.
Here’s what nobody tells you: domain authority matters, but not the way you think.
This isn’t some magic number that automatically puts you at the top of search results.
Google doesn’t even use it.
But the sites that rank? They all have something in common. They’ve built real authority, and that shows up in their domain authority score.
Let’s cut through the BS and talk about what domain authority actually is, how it works, and what you need to do to increase yours.
TL;DR: What Is Domain Authority?
Domain authority is a score from 1 to 100 that predicts how well your website will rank in search engines. Created by Moz, it measures your site’s overall strength based on backlink quality, linking domains, and other SEO factors.
Key points:
- Google doesn’t use domain authority as a ranking factor, but the things that improve your DA (quality backlinks, strong content, technical SEO) directly impact your rankings
- Compare your score to direct competitors, not arbitrary numbers
- The only way to increase domain authority is through earning high-quality backlinks from authoritative sites in your industry
- Track progress monthly since DA updates slowly
- Focus on building real authority (great content, strong links, technical excellence) rather than chasing the number itself
What Is Domain Authority?
Domain authority (DA) is a search engine ranking metric developed by Moz.
It’s a score between 1 and 100 that predicts how likely your website is to rank on search engine result pages.
The score uses machine learning to predict how often a domain appears in search results. Higher scores mean stronger ranking potential. A brand new site starts at 1.
Giants like Wikipedia sit at 77.
Here’s what matters: domain authority is predictive, not prescriptive. It’s not an official Google ranking factor. You can’t hand Google a DA score of 70 and expect page one rankings.
But here’s why it still matters. Sites with high domain authority typically have:
- Strong backlink profiles from reputable sources
- Quality content that attracts natural links
- Technical SEO that’s dialed in
- Brand recognition and traffic
All of these factors DO impact how Google ranks you. Domain authority is just the scoreboard showing how you’re doing on the things that actually matter.
Domain Authority vs Domain Rating vs Other Metrics
The SEO world loves creating confusing terminology. Let’s clear this up.
Domain Authority (DA) is Moz’s metric. It considers linking root domains, link quality, domain age, and multiple SEO factors.
Domain Rating (DR) comes from Ahrefs.
DR focuses specifically on backlink profile strength, measuring quality and quantity of referring domains.
It doesn’t consider domain age, traffic, or social signals.
Authority Score (AS) is SEMrush’s version.
It factors in backlinks, organic traffic estimates, and spam signals for a more holistic view.
Different tools, different calculations, different numbers. You might have a DA of 45, DR of 52, and AS of 38 for the same site. This is normal.
What this means for you
Pick one tool and stick with it for tracking progress. Don’t obsess over getting all three scores to match. They measure similar things differently.
The real insight? DR reveals backlink power while DA shows overall SEO strength. Use both for a complete picture.
How Domain Authority Works
Moz keeps the exact algorithm under wraps (smart move), but we know the major factors.
The Core Factors That Determine Your DA Score
1. Backlink Profile Quality and Quantity
This is the heavyweight. Both quantity and quality matter, a site with fewer than 100 high-quality backlinks from credible sources can have strong authority.
What counts as high-quality?
- Links from government sites (.gov)
- Academic institutions (.edu)
- Major news publications
- Industry-leading websites with high domain authority themselves
- Sites relevant to your niche
A single link from The New York Times carries more weight than 1,000 links from random blogs nobody’s heard of.
2. Number of Linking Root Domains
The variety and overall strength of your backlink profile matters, with unique domains linking to your website being particularly important.
Translation:
100 links from one website counts as one referring domain. 100 links from 100 different websites counts as 100 referring domains. The second scenario crushes the first for domain authority.
3. Link Quality Distribution
Not just who links to you, but how that link juice flows. Search engines evaluate:
- The authority of sites linking to you
- How many other sites they link to (fewer = more power per link)
- Whether links are dofollow or nofollow
- Link placement and context
4. Content Quality and Site Structure
High authority sites consistently publish content people actually want to read and reference.
This creates a flywheel: great content earns links, which increases authority, which helps content rank better, which earns more links.
5. Technical SEO Health
Core Web Vitals like speed, responsiveness, and visual stability impact authority signals.
A slow, broken site with poor mobile experience won’t build authority no matter how many links you get.
The Logarithmic Scale (And Why It Matters)
Domain authority uses a logarithmic scale where jumps between numbers get more difficult as you go up.
Getting from DA 10 to DA 20? Relatively easy. Getting from DA 60 to DA 70? Exponentially harder.
This is why obsessing over moving from 65 to 66 is pointless.
The real game is consistent, long-term improvement through quality fundamentals.
What’s a Good Domain Authority Score?
Stop looking for a magic number. There isn’t one.
Domain authority varies across industries, compare your score to direct competitors rather than targeting arbitrary numbers.
Industry Benchmarks (The Real Numbers)
Generally speaking:
- 1-20: New or very small sites with minimal backlinks
- 20-40: Established sites building momentum
- 40-50: Average sites with decent backlinks
- 50-60: Good authority, competitive in many niches
- 60-70: Strong authority, competitive in most niches
- 70-80: Very strong authority, major players
- 80-100: Industry leaders, household names (think Amazon, Google, Wikipedia)
But here’s the truth: if you’re a local plumber competing against other local plumbers, a DA of 35 might dominate your market.
If you’re in digital marketing competing against HubSpot and Neil Patel, you’ll need 60+ to play ball.
Your action step: Pull up your top 5-10 competitors. Check their domain authority using any domain authority checker tool. That’s your benchmark. Beat the average, and you’re winning.
How to Check Your Domain Authority
Multiple free tools let you check domain authority in seconds. Here are the best:

What to Look for When Checking DA
Don’t just look at the number. Check:
- Referring domains: How many unique sites link to you
- Total backlinks: Overall link volume
- Spam score: Are you getting links from sketchy sources
- Trend over time: Is your DA increasing, decreasing, or flat
A declining DA often signals lost backlinks or competitors outpacing you. Time to audit and adjust.
How to Increase Domain Authority (What Actually Works)
Let’s get tactical. Here are the proven strategies that move the needle.
1. Build High-Quality Backlinks (The Non-Negotiable)
There’s no hack, no shortcut, no secret sauce. One of the most effective ways to earn backlinks is creating valuable stats or data pages that bloggers and content creators reference.
Actionable tactics:
- Create linkable assets: Original research, industry surveys, comprehensive guides, tools, and calculators. Make something people WANT to link to.
- Guest posting on authority sites: Write for publications your audience reads. Include natural, relevant links back to your best content.
- Digital PR: Get featured in industry publications, podcasts, and news sites. One feature in TechCrunch beats 100 directory links.
- Broken link building: Find broken links on high-authority sites in your niche. Reach out offering your content as a replacement.
- Resource page link building: Identify resource pages listing tools, guides, or services in your industry. Pitch your content for inclusion.
What NOT to do:
- Buy links from link farms (Google will penalize you)
- Participate in link schemes or PBNs (private blog networks)
- Use automated link building tools
- Spam comment sections or forums with links
Quality over quantity. Always.
2. Fix Your Internal Linking Structure
Internal links help distribute link equity and enhance user experience, enabling search engines to crawl and index content efficiently.
Most sites waste 40-60% of their internal linking power by not connecting related content.
How to optimize:
- Link from high-authority pages to newer content you want to rank
- Use descriptive anchor text (not “click here”)
- Create topic clusters: main pillar page with supporting sub-articles
- Add contextual links within content, not just navigation
- Fix or remove broken internal links
3. Improve Your Content Quality (The Long Game)
Websites that publish well-researched, original, and engaging content regularly earn higher DA scores.
Average content gets average results. If you want links and authority, you need content worth linking to.
Content that earns backlinks:
- Original research and data studies
- Comprehensive guides (2,000+ words covering topics exhaustively)
- Tools and calculators
- Industry reports and trend analyses
- Controversial but well-argued opinions
- Case studies with real numbers and results
Publish consistently. One epic piece per month beats 20 mediocre blog posts.
4. Eliminate Toxic Backlinks
Not all backlinks help you. Some hurt.
Toxic backlinks from low-quality, spammy, or irrelevant websites can negatively impact authority and search rankings.
How to clean up:
- Run a backlink audit using Ahrefs, SEMrush, or Moz
- Identify links from spam sites, unrelated industries, or known link farms
- Use Google’s Disavow Tool to tell Google to ignore these links
- Regularly monitor new backlinks for suspicious sources
Most sites have some bad links. That’s normal. It’s the ratio that matters.
5. Nail Your Technical SEO Foundation
If your site loads slowly, breaks on mobile, or confuses crawlers, authority signals take a hit.
Technical checklist:
- Site speed: Aim for under 3 seconds load time
- Mobile optimization: Responsive design that works perfectly on phones
- HTTPS security: SSL certificate is non-negotiable
- XML sitemap: Help search engines find and index your content
- Clean URL structure: Logical, readable URLs
- Fix crawl errors: No broken links, 404s, or redirect loops
Technical SEO is the foundation. You can’t build authority on a broken website.
6. Build Topic Authority Through Content Clusters
Search engines reward domains that consistently cover their subject matter in depth using topic clusters.
Instead of random blog posts, create strategic content hubs.
The framework:
- Choose a core topic central to your business
- Create a comprehensive pillar page (3,000-5,000 words)
- Write 8-12 supporting articles diving deeper into subtopics
- Interlink everything strategically
- Update and expand over time
This signals to search engines: “We’re the authority on this topic.” Google rewards depth and breadth.
7. Leverage E-E-A-T Signals
Google prioritizes Experience, Expertise, Authoritativeness, and Trustworthiness.
Show you know what you’re talking about:
- Add author bios with credentials
- Include case studies with real data
- Cite authoritative external sources
- Display trust signals (certifications, awards, press mentions)
- Get expert contributors to write or review content
This matters especially for YMYL (Your Money Your Life) topics like health, finance, and legal advice.
Domain Authority Myths You Need to Stop Believing
Let’s kill some common misconceptions.
Myth 1: “High DA guarantees rankings”
False. Google does not use DA directly as a ranking factor. It’s a proxy metric. Focus on the underlying factors (backlinks, content, technical SEO) that both improve DA AND rankings.
Myth 2: “I can increase DA fast with link packages”
Paid link schemes usually backfire, Google can penalize manipulative link building. Quick DA boosts from sketchy services will get you penalized. Build authority the right way or don’t bother.
Myth 3: “DA 50 is good for everyone”
Context matters. Compare yourself to competitors in your specific niche, not broad industry averages.
Myth 4: “More backlinks always mean higher DA”
Quality crushes quantity. 10 links from The Wall Street Journal, TechCrunch, and Forbes beat 10,000 links from spam directories.
Myth 5: “Social media doesn’t impact DA”
Social visibility can earn more exposure and backlinks which do move the needle. While social signals aren’t direct ranking factors, viral content on social platforms attracts links from bloggers and journalists.
How Long Does It Take to Increase Domain Authority?
Real talk: Expect months, not weeks, it’s a long-term trust signal that compounds with consistent effort.
Here’s a realistic timeline:
Months 1-3: Implementing strategies, creating linkable content, starting outreach. Minimal DA movement (maybe 1-3 points if you’re aggressive).
Months 4-6: Links start accumulating, content gains traction. You might see 3-5 point increases.
Months 7-12: Compounding effects kick in. If you’re executing well, expect 5-10+ point increases depending on starting position.
Year 2+: Consistent gains of 5-15 points annually with sustained effort.
The higher your starting DA, the slower the progress due to the logarithmic scale. A site going from DA 15 to 25 happens faster than one going from 65 to 75.
Critical insight: Moz updates domain authority scores monthly based on their index. You won’t see daily changes. Check monthly, not weekly.
Domain Authority in 2025: What’s Changed
The SEO landscape evolves constantly. Here’s what matters now:
AI and Search Generative Experience (SGE): Google’s AI-powered search results are changing how people find information. But guess what sites get featured in AI answers? High-authority domains with quality backlinks and strong content.
E-E-A-T is now more important than ever: The extra “E” for Experience matters. Show real-world expertise, not just theoretical knowledge.
Quality over quantity has never been more true: Google’s helpful content update crushed thin, AI-generated spam. Only sites with genuine value and authority survived.
Niche authority beats broad mediocrity: It’s better to be the #1 authority in a specific niche than average across many topics.
The fundamentals haven’t changed. Build real authority through quality content and legitimate backlinks. The tactics might evolve, but the principles remain.
