If you have ever reviewed an SEO report or used a platform like Moz or Semrush, you have probably seen a metric called Domain Authority or Authority Score.
These scores can be useful for evaluating the overall strength of a website, but they are also commonly misunderstood.
The most important thing to know is this: Google does not assign websites a Domain Authority or Authority Score. Domain Authority was created by Moz, while Authority Score is a Semrush metric. Both are third-party tools designed to help marketers compare websites and evaluate SEO strength.
That does not mean they are unimportant. When used correctly, authority metrics can help you benchmark your website against competitors, review your backlink profile, and identify opportunities to improve your organic visibility.
The goal, however, should not be to chase a higher score. It should be to build a website that genuinely deserves more visibility.
Key Takeaways
- Domain Authority and Authority Score are third-party SEO metrics, not Google ranking factors.
- Moz uses Domain Authority (DA) to estimate how likely a domain is to rank in search results.
- Semrush uses Authority Score (AS) to evaluate factors such as backlink strength, organic traffic, and backlink quality.
- There is no universal “good” authority score. Your score is most useful when compared with relevant competitors.
- High-quality backlinks, useful content, internal linking, and strong technical SEO can all support website authority.
- Real SEO performance matters more than increasing a third-party score.
What Is Domain Authority?
Domain Authority, commonly called DA, is a metric created by Moz to estimate how likely a website is to rank in search engine results.
Scores range from 1 to 100, with higher scores generally indicating a stronger overall domain according to Moz’s model.
Domain Authority is influenced heavily by a website’s backlink profile, including the quality and quantity of websites linking to it.
However, Domain Authority belongs to Moz, not Google.
Google does not look at your DA score and decide where your pages should rank.
Instead, DA is most useful as a comparison tool.
If several competitors outranking you have much stronger authority metrics and backlink profiles, that may indicate that authority building should become a larger part of your SEO strategy.
What Is Authority Score?
Semrush uses a similar metric called Authority Score.
Authority Score also uses a 1–100 scale, but it is calculated differently from Moz Domain Authority.
Semrush considers factors such as:
- Backlink quality and quantity
- Estimated organic traffic
- Signals that may indicate an unnatural or spam-heavy backlink profile
Because the two platforms use different data and formulas, your Moz Domain Authority and Semrush Authority Score may not match. That is completely normal.
Neither number should be viewed as an absolute grade for your website. Their real value comes from comparing your website with relevant competitors and monitoring how your authority changes over time.
Does Google Use Domain Authority as a Ranking Factor?
No.
Google does not use Moz Domain Authority or Semrush Authority Score as direct ranking factors. Google uses its own ranking systems and signals to determine which pages best answer a search query.
Links are still part of that process. Google uses link analysis, including PageRank, to understand relationships between pages across the web.
Google also places significant emphasis on helpful, relevant, reliable content and a strong overall user experience.
That is why Domain Authority can still be useful even though Google does not use the score itself.
Many of the factors that contribute to stronger authority metrics, like quality backlinks, useful content, site structure, and organic visibility, also overlap with good SEO practices.
Think of Domain Authority as an indicator, not an objective.
What Is a Good Domain Authority Score?
There is no universal number every website should aim for.
A Domain Authority of 30 might be competitive in one industry and relatively weak in another.
A local service business should also not compare itself with a national media company or major ecommerce brand that has been earning links for decades.
Instead of asking:
“Is my Domain Authority good?”
Ask:
“How does my website compare with the competitors ranking for the searches that matter to my business?”
Consider comparing:
- Domain Authority or Authority Score
- Number of referring domains
- Quality of backlinks
- Organic traffic
- Keyword rankings
- Content depth
Trends over time are also more useful than obsessing over small fluctuations.
If your authority score gradually improves alongside organic traffic, rankings, and qualified leads, your SEO strategy is likely moving in the right direction.
How to Increase Your Website Authority
You cannot directly optimize for a Google “authority score.”
What you can do is strengthen the signals that make your website more credible, useful, and competitive.
1. Create High-Quality, Useful Content
Strong website authority starts with content that genuinely helps your audience.
That means moving beyond generic posts written only because a keyword has search volume.
Useful content should:
- Answer real customer questions
- Demonstrate genuine expertise
- Cover important topics in meaningful depth
- Support your core products or services
- Give readers a reason to return or share the page
Over time, a strong library of service pages, blogs, FAQs, case studies, and resources can help establish your business as a reliable source within its industry.
Your content should also connect naturally through internal links.
For example, a blog about improving website authority might link readers to resources about backlinks, SEO strategy, or improving organic visibility.
2. Earn Relevant, High-Quality Backlinks
Backlinks remain one of the most important elements associated with website authority.
A backlink is created when another website links to yours. But more backlinks do not automatically mean better SEO.
A relevant link from a respected industry publication, local media outlet, business association, supplier, or trusted resource can be much more valuable than dozens of links from low-quality websites.
Ways to earn stronger backlinks may include:
- Digital PR
- Industry publications
- Community involvement
- Business partnerships
- Sponsorships
- Original research
- Useful resources
- Expert contributions
Avoid shortcuts designed only to manipulate authority scores. Spammy or irrelevant backlinks may provide little value and can create unnecessary risk.
3. Improve Your Internal Linking
Internal links help users and search engines understand how your website fits together.
A well-organized site should naturally connect:
- Blogs to related blogs
- Blogs to service pages
- Service pages to supporting resources
- Case studies to relevant services
- Related topics to one another
The goal is not to insert links everywhere.
Every internal link should either help the reader better understand the topic or guide them toward a logical next step.
For example, readers interested in improving their organic visibility may naturally benefit from learning more about Brillity Digital’s SEO services.
4. Strengthen Your Technical SEO
Strong content and backlinks cannot reach their full potential if the website itself is difficult to use or navigate.
Technical SEO provides the foundation.
Important areas include:
- Website speed
- Mobile responsiveness
- Crawlability
- Clear navigation
- Logical URL structure
- Proper indexing
- Fixing broken links
- Internal linking
- Page titles and headings
- Overall user experience
A technically sound website makes it easier for both visitors and search engines to understand your content.
If your website is struggling to gain organic visibility despite publishing useful content, an SEO audit can help identify technical issues that may be holding it back.
5. Build Authority Around Your Core Topics
Your website does not need to become an authority on everything. It needs to build authority around the subjects that matter most to your business and customers.
For example, an electrical contractor might create interconnected content about:
- Electrical panel upgrades
- EV charger installation
- Home rewiring
- Lighting installation
- Electrical safety
- Frequently asked customer questions
That creates much stronger topical depth than publishing unrelated articles simply to increase content volume.
Think of website authority as something you build topic by topic.
6. Monitor the Right Competitors
Competitive analysis can help you understand what your website is up against. Look at competitors that actually rank for the keywords and searches you want to target.
Pay attention to:
- Which content earns backlinks
- Which topics they rank for
- How many relevant websites link to them
- What content gaps exist on your website
- Where your site already performs well
The goal is not to copy competitors. It is to understand the competitive landscape and identify opportunities to provide something more useful.
Domain Authority vs. Real SEO Performance
Domain Authority and Authority Score can be useful benchmarks, but they should never become your primary measurement of SEO success.
Your business needs customers, not a higher number inside an SEO platform.
Track authority scores alongside metrics such as:
- Organic traffic
- Keyword rankings
- Qualified leads
- Conversion rate
- Revenue from organic search
- Referring domains
- Backlink quality
The better question is not:
“Did our Domain Authority increase?”
It is:
“Is our website becoming more visible to the right audience, and is that visibility generating business?”
That is the outcome that ultimately matters.
Frequently Asked Questions About Domain Authority
Is Domain Authority a Google ranking factor?
No. Domain Authority is a metric created by Moz, while Authority Score is a Semrush metric. Google does not directly use either score to rank websites.
Does a higher Domain Authority mean I will rank higher?
Not necessarily. Websites with stronger authority metrics often have characteristics associated with good SEO, such as quality backlinks and strong organic visibility, but rankings also depend on relevance, content quality, competition, search intent, and other factors.
Are backlinks still important for SEO?
Yes. Links remain an important part of how search engines understand relationships and authority across the web. However, backlink quality and relevance matter more than simply accumulating a large number of links.
Should I focus on Domain Authority or organic traffic?
Use Domain Authority as a supporting benchmark. Your primary focus should be meaningful business outcomes such as qualified organic traffic, rankings, leads, conversions, and revenue.
Build Real Website Authority, Not Just a Higher Score
Domain Authority and Authority Score can help you understand your competitive position and monitor SEO progress, but they are not the ultimate goal.
Real website authority comes from consistently giving users and search engines reasons to trust your site.
That means publishing valuable content, earning relevant backlinks, strengthening your technical foundation, improving internal linking, and building genuine expertise around the topics that matter most to your customers.
At Brillity Digital, our SEO services focus on that bigger picture. We evaluate content, technical performance, backlinks, competitors, search visibility, and conversion opportunities to identify the strategies most likely to move your business forward.
A stronger authority score may follow.
