Domain Authority falls under the category of Off-page SEO metrics.

It’s a predictive ranking score developed by Moz that estimates how likely a website is to rank in search engine results pages (SERPs).

While not an official Google ranking factor, it’s considered part of off-page SEO because it primarily measures external factors like:

• The quantity and quality of backlinks pointing to your domain
• The authority of the sites linking to you
• The overall link profile of your website

Unlike on-page SEO factors (which focus on content optimisation and technical elements within your website), Domain Authority looks at external signals that indicate your site’s reputation and trustworthiness across the broader internet ecosystem.

However, it’s worth noting that Domain Authority intersects with other SEO categories as well, particularly technical SEO, since factors like site structure and crawlability can indirectly impact your ability to build authoritative backlinks.

Although DA is not the only way website authority is measured, it is widely used and recognised.

Generally, Domain Authority is scored on a scale from 0 to 100. A brand-new website will have a DA of 0, while the highest DA currently is Facebook, which is a maximum of 100.

The DA figure considers around 40 different SEO elements of a website. While this doesn’t provide a complete picture of your website’s SEO (Google’s algorithm factors in over 200), it does indicate how your site compares to others and whether you can expect to rank higher or lower.

Two key points about how Domain Authority changes:

DA changes do not happen overnight; it takes time to see movement.

The higher your DA, the harder it becomes to make large upward movements compared to lower DAs.

For example, moving from a DA of 65 to 75 is more difficult than moving from 25 to 35.

5 Ways to Improve Your Domain Authority:

Domain Authority (DA) is a ranking metric that predicts how well a website will perform in search engine results.

While it’s not a direct ranking factor for Google, a higher DA score indicates strong credibility, quality backlinks, and a well-optimised website.

Improving your DA requires a combination of strategic content creation, backlink building, and technical SEO.

1. Create high-quality, linkable content that naturally attracts backlinks.

One of the best ways to earn backlinks naturally is to create useful, in-depth content. Don’t just write generic articles. Instead, focus on:

• Solid how-tos and other guides that take a deep dive into one subject.
• Calling all original research, data studies, or surveys that other sites will backlink to.
• Expert opinion that provides something different from what competitors are providing.

Content that solves problems and offers original insights gets shared and linked to by high-authority sites.

2. Build quality backlinks through targeted outreach and relationship building.

Not all backlinks carry the same weight. Building relationships matters for the long-term growth of your DA, because Google favours links from good-quality, relevant sites. Strategies include:

• Writing guest posts for popular industry blogs to establish authority.
• Participating in expert roundups where several professionals share their insights.
• Examples include pitching journalists and industry publications to earn mentions via digital PR.

Instead of chasing low-quality, spammy backlinks, aim for links that genuinely add to your site’s authority.

3. Audit and remove toxic backlinks regularly.

A strong backlink profile is about building good links, and it’s also about removing the bad ones. Backlinks from spammy websites or low-quality sites can also hurt your DA and search rankings. Maintain a clean profile by:

• How to monitor your backlink profile with Google Search Console or third-party tools.
• Detecting irrelevant, spammy, or unnatural links and disavowing them.
• Staying away from link schemes or payment backlinks because Google penalises manipulative link building tactics.

Auditing your link profile regularly keeps your website’s reputation clean and helps you avoid search engine penalties.

4. Improve your internal linking structure and technical SEO.

External backlinks have the biggest effect on DA, but a well-structured site helps search engines crawl it properly and gives users a better experience. Key areas to focus on:

• Internal linking with logic to connect correlated pages and authority.
• Mobile-friendliness and page speed, because slow or unresponsive websites drive visitors away and hurt SEO.
• Well-defined site architecture that is easy for users and search engine crawlers to move through.

A technically sound website is easier to find, and it is more likely to earn backlinks.

5. Focus on building your brand presence and social signals.

Social signals are not direct ranking factors, but they do affect how many people see your content and your brand, which can lead to more backlinks. Here are some ways to build your brand’s presence online:

• Create shareable content that inspires interaction.
• Engage with discussions relevant to your industry on LinkedIn, Twitter, and forums.
• Join forces with influencers who are able to spread your content across a wider reach.

The more people see your content, the better your chances of earning natural backlinks from authoritative sites, which lifts your DA.

Building Domain Authority takes time, but creating valuable content, earning quality backlinks and optimising the technical side of your site will help your website gain more trust and visibility in search results.
