Domain Authority (DA)

Moz's proprietary 1–100 metric predicting how likely a domain is to rank in SERPs, based on backlink quality and quantity. Not a Google metric.

Definition

Domain Authority (DA) is a proprietary metric developed by Moz that predicts how well a domain is likely to rank in Google SERPs. It is calculated on a logarithmic scale from 1 to 100 using backlink quality, quantity, and diversity. DA is widely used in the SEO industry as a shorthand for link authority, but it is not a metric Google uses internally — it is Moz's approximation of link strength based on Moz's own crawl data.

Why it matters for SEO

DA is useful as a relative benchmark when comparing sites or evaluating link-building targets — a DA 60 site generally has more link authority than a DA 20 site. It should not be treated as an absolute ranking predictor. Google's actual ranking algorithm considers hundreds of signals beyond backlink quantity, and there have been well-documented cases of high-DA sites being outranked by lower-DA, more relevant pages. Use DA for directional comparison, not as a target metric to optimize for directly.

How DeepSEOAnalysis checks this

DeepSEOAnalysis does not calculate or display Domain Authority — it is a Moz proprietary metric requiring Moz's database. The audit focuses on signals that can be directly measured from your site: internal link structure, external link profile signals available from crawl data, broken outbound links, and structured backlink patterns. For DA-based analysis, you need a Moz account or a tool that licenses Moz data.
