What is domain authority?
Domain authority (DA) is a search engine ranking score developed by Moz that predicts a website's likelihood of ranking in search engine result pages (SERPs). DA scores range from one to 100, with higher scores corresponding to a greater likelihood of ranking. DA is calculated by evaluating multiple factors, including linking root domains, the number of total links, and MozRank. MozRank is a metric developed by Moz that measures the strength of a website's link profile.
It's important to note that DA is not a metric used by Google or other search engines. Instead, it's a third-party metric that can help SEO professionals and website owners understand how their site performs regarding its backlink profile.
How is domain authority calculated?
Domain Authority is calculated by evaluating dozens of factors. Moz's algorithm uses machine learning to find the "link juice" of a given page and then applies this to the domain as a whole. Moz uses a logarithmic scale to calculate DA, which means improving your score from 20 to 30 is much easier than from 70 to 80.
What influences your domain authority score?
Many factors can influence your domain authority score, but the most important is the quality and quantity of your website's backlinks. Backlinks are links from other websites to your website. When a high-quality website links to your website, it's like a vote of confidence. This tells search engines that your website is trustworthy and authoritative.
Other factors that can influence your domain authority score include:
- The age of your domain
- The quality of your website's content
- The overall user experience of your website
- The technical SEO of your website

How to increase domain authority
There are several things you can do to increase your domain authority. Here are a few of the most effective strategies:
1. Develop high-quality, research-driven content
One of the best ways to increase your domain authority is to create high-quality content that other websites will want to link to. This content should be well-written, informative, and engaging. It should also be relevant to your target audience.
2. Find outlets for guest posts
Guest blogging is a great way to get backlinks from high-authority websites. When you guest blog, you write an article for another website in your industry. In exchange, you get a backlink to your website.
3. Focus on earning links and repair broken links
Backlinks are still one of the most important ranking factors. Focus on earning high-quality backlinks from authoritative websites in your industry. You can also use tools like Ahrefs and Semrush to identify broken links on other websites and reach out to the website owner to suggest a replacement link to your website.
4. Promote your content on social media and other online channels
Promoting your content on social media and other online channels can help you get more backlinks. When you share your content on social media, people are likelier to see and link to it.
5. Keep your website up-to-date with fresh content and new features
Keeping your website up-to-date with fresh content and new features can help you attract more visitors and backlinks. Adding new content to your website gives people a reason to come back and revisit your site. This can also help you improve your search engine rankings.
