Everymonth, thousands of business owners receive SEO reports with a number called Domain Authority sitting prominently at the top. The number went up. The agency takes credit. The client feels good. And rankings may or may not have moved at all.

Domain Authority is a third-party metric created by Moz. Google has explicitly stated, repeatedly, that it does not use Domain Authority as a ranking signal. It never has. Your DA score is a measurement of what Moz's algorithm thinks about your link profile — not what Google thinks.

What Google Actually Uses

Google's ranking systems evaluate hundreds of signals, but the ones that actually move the needle for most businesses fall into three categories: the quality and relevance of content on your pages, the authority and relevance of sites linking to you, and technical signals that determine whether Google can efficiently crawl and index your site.

None of those translate cleanly into a single number. Which is exactly why DA is so appealing to agencies — it gives clients a proxy they can understand without requiring the agency to explain the messy, multifactorial reality of how search actually works.

The agencies who sell DA improvements are not lying to you. They're selling you a metric that measures their activity, not your business outcomes.

What to Measure Instead

Keyword Ranking Movement

Track your positions for specific, commercially relevant keywords — not vanity terms, not broad terms with zero buying intent. The keywords that matter are the ones your prospective customers are typing when they're ready to take action.

Organic Traffic to High-Intent Pages

Total organic traffic is a vanity metric if it's driven by blog posts that attract curiosity but no commercial intent. The number that matters is traffic to your service pages, location pages, and conversion-focused content.

Organic Leads and Revenue

The ultimate SEO metric is leads or revenue attributed to organic search. If your SEO agency can't show you this number — or worse, actively avoids discussing it — that tells you everything you need to know about what their work is actually delivering.

The Link Building Question

Domain Authority is primarily driven by backlinks, which is why agencies obsess over it — they sell link building packages and DA is how they prove the links are "working." But backlink quality is not captured in a single score. A link from a relevant industry publication is worth more than 50 links from generic guest post farms, regardless of what either does to your DA.

The right question is not "did our DA go up?" The right question is "did we earn links from sites our prospective customers actually read, on topics directly related to our services?" That's what moves rankings.
