Brand Authority vs Domain Authority: Which One Actually Moves Your Business Forward?

 

If your marketing agency sends you a monthly report with a Domain Authority score on it, you have probably wondered at some point what it actually means for your business. It looks important. It has a number attached. But does it tell you whether more customers are finding you, trusting you, and choosing you over a competitor?

The question of brand authority vs domain authority matters because the answer determines how you spend your time and budget. And the data now points clearly in one direction.

We are going to walk you through what Domain Authority is, what Brand Authority is, how they differ, and what your business should actually be focused on building. We have also written about the basics of brand authority and why it matters for your search ranking if you want a foundation before diving into the comparison.

 

What is Domain Authority, and where did it come from?

Domain Authority, or DA, is a score created by Moz in 2004. It predicts how likely a website is to rank on search engine results pages and uses a scale from 1 to 100. The higher the number, the stronger the prediction.

DA is calculated using a machine-learning model that looks at two main inputs: the number of websites linking to your domain and the quality of those links. Because the scale is logarithmic, moving from a DA of 20 to 30 is much easier than moving from 70 to 80.

The score became popular because it gave agencies and SEO professionals a simple number to present to clients. It is one of the most widely referenced metrics in the SEO industry. But there is a significant problem with how it is commonly used.

Google does not use Domain Authority. At all.

This is worth saying directly. Moz created Domain Authority. Google did not. And Google does not use it.

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

Google’s own John Mueller has said it twice on the record. In 2020: “Just to be clear, Google doesn’t use Domain Authority at all when it comes to Search crawling, indexing, or ranking.” And in 2022 on Reddit: “Google doesn’t use it at all. I don’t think I’ve ever looked up the DA for a site in the 14 years I’ve been doing this.”

Ahrefs, which makes its own competing metric called Domain Rating, says the same thing on its support page: “There’s no evidence that search engines use Domain Rating (or similar scores such as Domain Authority) as a ranking factor at all.”

So why does DA still show up in agency reports? Because it is a useful benchmark for comparing your site to competitors and tracking link-building progress over time. That is a legitimate use. The mistake is treating it as a goal, or as proof that your business is visible to the people who matter.

 

What is Brand Authority?

Brand Authority is a measure of how well-known and trusted your brand is across the web. Moz launched it as a formal metric at its MozCon conference in August 2023, with a score on a scale from 1 to 100.

According to Dr. Peter J. Meyers, Moz Marketing Scientist: “Brand Authority combines Moz’s knowledge of search intent and search volume to calculate a score that reflects the total strength of a website’s branded search terms.”

In plain terms: Brand Authority measures how many people search for your business by name, how often, and with what level of intent. It is a reflection of your reputation, not just your backlink profile.

The concept goes beyond the Moz metric. Brand authority in the broader sense means your business shows up consistently across the web: people mention it, write about it, review it, and search for it by name. That pattern of recognition is what Google is increasingly built to detect and reward.

 

Brand authority vs domain authority: what each one actually tells you

Domain Authority tells you how strong your website’s backlink profile is relative to every other website on the internet. It is a technical signal. It helps you understand whether a link from a particular website is worth pursuing. And it is useful for SEO professionals doing competitive analysis.

Brand Authority tells you how recognizable your business is to the people you are trying to reach, and increasingly, to the AI systems those people use to find answers. It reflects the strength of your reputation across search, media, reviews, and your general online footprint.

Here is what each one does not tell you:

• A high DA score does not mean buyers trust your brand or know who you are. A site can have a DA of 60 from years of link-building and still be invisible in AI search results.
• A high Brand Authority score does not guarantee a top ranking for every keyword. But it increasingly predicts whether your business shows up in the answers AI tools generate for your potential customers.

The practical difference for your business: DA is a signal to SEO tools. Brand Authority is a signal to Google, AI search engines, and buyers who are already looking for someone they recognize.

 

What the 2024 Google leak revealed about brand signals

In May 2024, internal documentation from Google’s Content Warehouse API was made public. The files contained 2,596 modules and 14,014 attributes describing how Google’s search system works internally. Google confirmed the documents were authentic.

The leak was significant because it confirmed something Google had publicly denied for years: that the company uses a site-wide authority metric internally, referred to in the documentation as “siteAuthority,” which feeds into Google’s quality ranking system. This is not Moz’s Domain Authority. This is Google’s own internal measure of how much weight to give a website based on its reputation and entity footprint.

The documentation also confirmed signals like “siteFocusScore” and “siteRadius,” measuring how topically focused your site is, and “authorReputationScore,” measuring how credible your content authors are.

Rand Fishkin, who first published the leak findings in Search Engine Land, put it directly: “If there was one universal piece of advice I had for marketers seeking to broadly improve their organic search rankings and traffic, it would be: Build a notable, popular, well-recognized brand in your space, outside of Google search.”

Moz’s Tom Capper also noted that the documents suggest Google uses a “Branded Search Ratio” to influence how a site performs for non-branded searches. The more people search for your brand by name, the better your site tends to perform, even for searches that have nothing to do with your brand name directly.

 

Why this matters even more now that AI search is mainstream

Search is changing faster than most businesses realize. Google’s AI Overviews reached 2 billion monthly users as of Q2 2025, and AI Mode had over 100 million monthly active users. These are not small numbers. They represent a fundamental shift in how buyers find answers.

A McKinsey survey published in October 2025 found that half of consumers now intentionally seek out AI-powered search engines, with a majority saying it is their top digital source when making buying decisions. Among B2B buyers, 73% now use AI tools such as ChatGPT and Perplexity during their research process.

And here is where the brand authority vs domain authority question becomes most important. Ahrefs studied 75,000 brands and found that branded web mentions correlate with AI Overview visibility at 0.664, compared to just 0.218 for backlinks. That is roughly three times stronger. The brands that show up in AI-generated answers are overwhelmingly the ones with the strongest off-site brand presence.

The numbers get sharper when you look at the extremes. Brands in the top 25% for web mentions average 169 appearances in AI Overviews. Brands in the bottom 50% are described by Ahrefs researchers as “essentially invisible to AI systems.” And 26% of all brands studied had no appearances in AI Overviews at all.

If you are running Google Ads or Facebook Ads alongside your organic efforts, our breakdown of which paid platform belongs at which stage of the buyer journey is also worth reading alongside this.

 

What this means for your business in practice

Almost half of all Google searches, 45.7% according to Ahrefs’ study of around 150 million US keywords, are branded. People search for specific businesses, not just generic terms. Branded traffic also converts at higher rates because the intent behind it is stronger.

B2B buyers now use an average of ten channels across the purchasing journey, up from five in 2016. By the time a potential customer contacts your business, most of their decision has already been shaped by what they read, researched, heard, and seen about you before that moment.

Your Google Business Profile plays a more direct role than many businesses expect. Customers are 2.7 times more likely to consider a business reputable when it has a complete profile. Review signals now account for around 20% of Google Local Pack ranking weight. We put together a full guide on how to optimize your Google Business Profile if you want to work through this step by step.

The businesses that outperform competitors in search and AI visibility are the ones showing up consistently in places their buyers already pay attention to: industry publications, trade press, third-party review platforms, and searches that include their name.

 

Four (4) ways to start building Brand Authority

Brand authority builds over time through consistent presence across the web. These four actions give you the highest return on that effort.

1. Earn third-party mentions and press coverage: 82% of all AI citations come from earned media, and 94% come from non-paid sources, according to analysis of over one million AI-cited links across ChatGPT, Claude, Gemini, and Perplexity. Getting your business mentioned in industry publications, local news, trade press, and niche blogs is the highest-impact thing you can do for AI and organic visibility at the same time.

2. Build your review volume consistently: 98% of people read online reviews before engaging with a local business. Reviews also make up around 20% of Google’s Local Pack ranking algorithm. A steady flow of genuine reviews, responded to promptly, signals the kind of trust that both buyers and search engines recognize. Check out our guide on what to look for in a marketing agency to see how we approach this for clients.

3. Grow your branded search volume: Branded search volume is the clearest signal of whether your business is becoming more recognizable over time. When more people search for your business by name, Google treats that as a trust signal. It improves your site’s performance, even for searches unrelated to your brand name. Track it monthly and treat growth as a leading indicator.

4. Stay consistent and specific about what your business does: The Google leak confirmed signals like “siteFocusScore” and “siteRadius,” which measure how topically consistent your site and brand presence are. Being clearly, consistently known for one thing in your industry builds the kind of entity recognition that both Google and AI tools reward.
