What Is Domain Authority?
Domain Authority is a third-party SEO score that estimates how a website may perform in organic search, based mainly on the quality and strength of links pointing to its domain. Domain Authority helps compare competing websites, but it is not a Google ranking factor and does not predict rankings for individual keywords.

Key Takeaways About Domain Authority
- Domain Authority is a third-party comparison metric.
- Relevant, credible links can strengthen a domain’s profile.
- A higher score does not guarantee higher rankings.
How Domain Authority Works
Domain Authority is calculated by SEO platforms from signals in a website’s backlink profile. The calculation can consider the number, quality, relevance, and trust of linking domains. Each platform uses its own method, so scores from different providers are not directly interchangeable.

Link building teams use the metric as a comparison aid during prospect research and campaign review. A relevant link from a respected industry publication may carry more strategic value than many weak or unrelated links. The score describes the domain’s link profile, not the quality of every page, the suitability of its content, or its ability to rank for a particular search.
Expert Note
When we assess Domain Authority, we treat it as one screening signal within a wider link review. We check the linking site’s relevance, editorial quality, audience fit, and backlink profile before deciding whether a link opportunity supports the campaign.
Domain Authority in Practice: A Real-World Example
A local Adelaide plumber may find a trade publication with a stronger Domain Authority than a general directory. The publication could be the better link prospect if its readers, topic, and editorial standards match the plumber’s services.
