Domain authority (DA) is a system of measuring how authoritative a website is, created by leading SEO tool Moz. Although similar to Page Authority, another measure provided by the software company, Domain Authority is a metric for the entire domain as opposed to the individual page.

It’s based on a range of different factors using data drawn from Moz’s Link Explorer web index, including a site’s total number of links and root domains. Although DA is not a direct ranking factor, and isn’t tracked by Google, it remains a useful indicator for assessing both the ranking potential of your site, and the potential value of links from outside referring domains.

Checking domain authority is a routine step when most SEOs begin working on a site. Moz maintains a free Free Domain Analysis Tool on their website, so even if you’re not paying for the full tool, you’ll be able to keep an eye on your site’s DA as you work to optimise it.

Domain authority is scored on a scale from 0 to 100, with 100 being the highest. Authority scores average between 40 and 50, so anything above 50 can be considered good. The 60 mark is a tough barrier to break for most sites, so anything above 60 can be considered excellent! A minority of long-established and highly popular sites, for example Wikipedia, have DA scores in the 90s.

Many link builders consider the domain authority of a website before reaching out for links, as gaining links from high authority websites is extremely beneficial. However, while domain authority is important, it is not the only important metric, and assessing the true value of a site will require a more granular look at a range of other authority factors.

Moz Domain Authority (DA) FAQs

How do you increase Domain Authority?

You can increase domain authority by following established SEO best practices, such as acquiring high quality backlinks, creating and promoting valuable, authoritative content, optimising your onsite user experience, and keeping your link profile free of toxic, spammy links.

Does Domain Authority affect rankings?

No. Domain Authority is a measure of a domain’s power, based on its link profile and a number of other metrics. It is an indicator of how strong a domain is, and therefore how likely it is to rank – but it has no influence on the ranking positions.

Moz even stated: “Domain Authority is not a metric used by Google in determining search rankings and has no effect on the SERPs.”
