Domain Authority is one of the most widely recognised metrics in SEO.
Originally developed by the SEO software company Moz, Domain Authority was created to estimate how likely a website was to rank within search engine results pages. The score ranges from 1 to 100, with higher scores generally indicating a stronger ability to compete for search visibility.
Although Google does not use Domain Authority as an official ranking factor, it remains a useful benchmark for understanding the overall strength of a website.
How is Domain Authority measured?
Domain Authority is calculated using a combination of factors that help estimate the credibility and authority of a website.
These typically include:
- The number of backlinks
- The quality of backlinks
- The number of referring domains
- The authority of linking websites
- Overall link profile strength
The stronger these signals become, the higher the Domain Authority score is likely to be.
Domain Authority should be viewed as a comparative metric rather than an absolute measure of success.
Why does Domain Authority matter?
Whilst Google does not directly use Domain Authority as part of its ranking algorithm, it remains useful for measuring progress and benchmarking performance.
Businesses often use Domain Authority to:
- Compare themselves against competitors
- Assess the effectiveness of link-building campaigns
- Measure growth over time
- Evaluate off-page SEO performance
- Understand the strength of their backlink profile
A rising Domain Authority score is often a positive sign that your website’s authority and visibility are improving.
What influences Domain Authority?
The biggest factor affecting Domain Authority is the quality of websites linking to you.
For example, a link from a respected national publication will usually contribute far more authority than a link from a low-quality directory website.
This is because search engines place greater value on endorsements from trusted sources.
Generally speaking, the strongest authority profiles are built through:
- High-quality backlinks
- Relevant industry citations
- Trusted referring domains
- Consistent content publishing
- Strong brand recognition
Quality will almost always outperform quantity.
Why does Domain Authority operate on a logarithmic scale?
One of the most misunderstood aspects of Domain Authority is that it operates on a logarithmic scale.
This means that progress becomes increasingly difficult as scores rise.
For example:
- Moving from 10 to 20 can be achieved relatively quickly.
- Moving from 20 to 30 requires more effort.
- Moving from 70 to 80 can take years and often requires links from extremely authoritative websites.
This is why comparing a local business website to a global brand is rarely useful.
The objective should be continuous improvement rather than chasing an arbitrary score.
Does Domain Authority matter for AI search?
Not directly.
Large language models such as:
- ChatGPT
- Claude
- Perplexity
- Google Gemini
do not use Domain Authority scores created by Moz.
However, many of the signals that contribute to Domain Authority are still important.
These platforms seek to identify trustworthy and authoritative sources when generating answers.
As a result, websites with strong authority profiles often have an advantage when it comes to visibility and citations.
What is Google E-E-A-T?
When discussing authority, it is important to understand Google’s E-E-A-T framework.
This stands for:
- Experience
- Expertise
- Authority
- Trust
These principles help Google evaluate the quality and credibility of content.
Many of the activities that improve Domain Authority also contribute towards stronger E-E-A-T signals.
For example:
- Earning citations from respected websites
- Demonstrating subject expertise
- Building a recognised personal brand
- Publishing authoritative content
These factors help establish trust across both traditional search engines and AI-powered search platforms.
Does Google rank domains or pages?
This is an important distinction.
Google primarily ranks individual pages, not entire websites.
A strong domain can make it easier for new content to rank because the website has already established authority.
However, even a high-authority website can struggle if the content on a specific page is weak.
Ultimately, high-quality, relevant content remains the deciding factor.
The page that best answers the user’s question is often the page that wins.
How can you improve Domain Authority?
Improving Domain Authority is a long-term process that focuses on building trust and authority over time.
Effective strategies include:
- Publishing valuable content
- Earning high-quality backlinks
- Creating original research
- Building industry partnerships
- Securing digital PR coverage
- Developing thought leadership
Content sits at the heart of all of these activities.
Without useful content, there is little reason for other websites to link to you.
