What Domain Authority is and how to improve it
The Domain Authority is an essential concept in the SEO and digital marketing. Throughout this article, we explore in depth what it means, how it is measured and what strategies we can implement to improve it.
What is Domain Authority?
Definition and origin of the concept
The Domain Authority (Domain Authority or DA) is a metric developed by Moz that evaluates the "strength" of a website and its potential to rank in search results.
The DA score ranges from 1 to 100 and is calculated based on multiple factors, such as the quality of inbound links, the relevance of the content and the structure of the site. The higher the DA, the higher the likelihood of the site appearing at the top of Google.
The DA was conceived to provide a quick reference on the "sorting potential". of a domain, based on the link profile and authority generated by the sites linking to it. Although Google does not use this metric directly, the DA has become a standard among the SEO consultants to evaluate the performance of a site.
Why is domain authority important in SEO?
A high domain authority indicates a reliable and well-established site, which is crucial for gaining search engine visibility. As Google's algorithms value quality and relevance, sites with high DA tend to rank better for relevant searches.
Although having a high DA does not guarantee first place, it does facilitate ranking, as the metric reflects the robustness of the site in terms of links and content quality.
However, it should be noted that all third-party domain metrics tools have their flaws, weaknesses and inaccuracies when it comes to measuring DA.
How Domain Authority is measured
Main tools for calculating domain authority
Moz Domain Authority Checker
The Moz Domain Authority Checker is the most popular tool for measuring domain authority. By simply entering the URL of your site, you can get the DA score, which is based on factors such as the number of links, their quality and the structure of the page. Moz also provides information on page authority (PA) and inbound links.
In general, Moz's suite of tools can be of great help in planning your digital marketing, SEO and marketing strategies. link building. When used and understood correctly, it can also help you identify fake domain metrics; however, only a small percentage of its users actually know how to do this identification.
Moz currently uses around 40 factors to calculate the DA score, including linking root domains, total number of links, rel attributes and other elements.
Ahrefs and SiteGround: Authority checkers and calculators
In addition to Moz, other tools such as Ahrefs y Semrush provide domain authority checkers. Ahrefs, for example, uses its own Domain Rating (DR) system that measures the quality and quantity of backlinks.
Factors influencing domain authority
Domain authority does not depend on a single factor, but on a combination of elements such as:
- Incoming links: The more quality backlinks your site has, the better your DA will be.
- Quality of backlinks: Links from high authority sites are more valuable. In addition, receiving high authority links directly related to your industry is highly valued by Google.
- Relevant content: Publishing useful, up-to-date and optimised content improves authority.
- User experience (UX): The speed and usability of the site impact on DA.
- Balance Follow No Follow: There must be a balance between follow and no follow links.
- Anchor text naturalness: The naturalness of anchor texts is also important: linked keyword, texts such as "click here", full url, ect are fundamental to estimate the quality and transfer authority of the website through these backlinks.
- Age of the domain or antiquity: It is important that the domain has a certain length of time and that it is reserved for at least two years onwards.

What is considered a good Domain Authority?
Reference values
The domain authority scale is logarithmic, which means that it is easier to go from 10 to 20 than from 70 to 80. A DA score between 40 and 50 is good for medium sites, while values above 60 indicate high authority sites. Reference sites such as Wikipedia or Facebook have DA scores close to 100.
How much does a high authority really affect?
Although a high DA can facilitate positioning, it does not automatically guarantee good SEO results. Search engines prioritise relevant content and user experience. However, a high DA in combination with good SEO practices will increase the site's visibility in relevant searches.
How can I know the authority of my domain?
Steps to verify a website's domain authority
- Log in to Moz, Ahrefs or SEMrush.
- Enter your site's URL in the domain checker.
- It analyses the DA along with other metrics such as the number of backlinks and the quality of the referring domains.
How to interpret results and make decisions
A high DA score is positive, but must be interpreted in conjunction with the backlink profile and page performance. While a high DA is favourable, steps should be taken to maintain the quality of the content and further optimise the site.
Tips for improving Domain Authority
Effective link building strategies
Link building is key to improve the DA. Some useful tactics are:
- Create quality content: Relevant and valuable content attracts links organically.
- Collaborate in guest posting: Writing on other sites improves visibility and domain authority.
- Local directories and citations: These links help especially in Local SEO and are valued by Google.
Content optimisation and on-page SEO
Page structure and content optimisation are essential for a high DA. Include relevant keywords, optimise titles and descriptions and use appropriate tags to improve performance in search results.
Improving the user experience (UX)
User experience is vital for SEO. Google values loading speed, intuitive navigation and responsive design. Improving these aspects not only boosts authority, but also generates greater visitor satisfaction.
Myths and realities of Domain Authority
Difference between page authority and domain authority
The domain authority refers to the positioning potential of the entire site, while the page authority (Page Authority or PA) evaluates the relevance of an individual page. Both indicators are useful to understand the "strength" of a site, but they should be analysed together.
The limits of Moz's metrics and their reliability
Moz DA is useful for checking authority, but it is not a definitive measure. Google does not use DA to rank sites. In addition, DA can be manipulated by low-quality links, which means that the score does not always reflect the true value of a site.
Tools such as Ahrefs and SEMrush are alternatives that can complement the authority analysis.
The importance of Domain Authority for your SEO strategy
Domain authority (DA) is a crucial metric in SEO, but it is not the only one that matters. Using tools like Moz, Semrush o Ahrefs allows you to evaluate and improve the "strength" of a site. However, concentrating exclusively on this metric can be unreliable or lead to wrong conclusions.
Improving domain authority requires a combination of a good quality link building strategy, on-page optimisation and an optimised user experience. In short, DA is a key metric in SEO strategy, but it must be complemented with good practices to achieve the best results in search engines.
A website's DA score is by no means a direct correlation of its value in search results (SERP). Obsessing over DA means focusing on a third-party metric that has almost no real value. For example, a site with an organic DA score of 10 may be even more beneficial in terms of SERP than a domain with DA 20.
It is recognised that search engines have over 200 ranking factors. Basing your SEO campaign on third-party domain metrics alone is setting yourself up for failure. Do your research and learn how to use metrics tools to your advantage.
It is estimated that over 90% of global SEO services, particularly among freelancers, are fraudulent and will not produce results. For assistance with your SEO or digital marketing campaign, it is best to go with a reputable agency with a clear strategy and a legitimate client portfolio.

SEO KPIs as well as business objectives should go hand in hand. However, as an SEO Consultant, more often than not, I come across online businesses without defined objectives and therefore without indicators because they don't know what to measure.

SEO KPIs are metrics that help companies measure the success of a particular initiative, in this case, the launch and performance of a new website or an already published one.
