Domain Rating is not a Google metric. Domain Authority is not a Google metric. Authority Score is not a Google metric. These are third-party scores — Ahrefs’, Moz’s, Semrush’s — and Google has said directly, more than once, that it does not use them to rank anything. John Mueller’s version: “We don’t use domain authority; that’s a metric from an SEO company.”
So when an agency reports that your Domain Rating moved from 31 to 34 this quarter, what actually happened is a third-party crawler updated its estimate of your backlink profile. That’s not nothing. It correlates loosely with how Google’s own systems might weigh your site. But it is not an asset. You cannot sell it, borrow against it, or take it with you if you switch platforms. It is a number a company you don’t pay calculated about you, using a methodology you don’t control, that can move for reasons that have nothing to do with anything you did.
Your subscriber list doesn’t have any of those problems.
What a subscriber actually is
A subscriber is a person who gave you their email address, which is the closest thing to a permanent, portable address a person has online. You can export that list today and import it into a different platform tomorrow. Nobody can deprecate it, change its algorithm, or decide it no longer qualifies for organic reach. It does not depend on a crawler’s opinion of your backlink profile, and it does not evaporate when a growing share of searches resolve inside an AI answer instead of sending anyone to your site.
It is also valuable in ways that show up on an actual balance sheet, not just a dashboard. Acquirers value email lists directly — list size, engagement rate, and list age are standard diligence line items in any deal involving a media or content business. Nobody asks for your Domain Rating during an acquisition. They ask how many people open your emails.
The math nobody runs
Here’s what I think happens: a business spends six months and several thousand dollars moving its Domain Rating from 28 to 33. That’s real work — link building, content, technical fixes. And it might do something. It might not. The relationship between that score and actual qualified traffic is loose enough that nobody can tell you, in advance, what five points of DR is worth in dollars.
Compare that to 500 real subscribers with a 35% open rate — a perfectly normal number for a well-run niche newsletter. That’s 175 people opening an email from you, on purpose, on a day you chose, about a thing you decided to say. You know exactly what that’s worth, because you can watch it convert. You can put an offer in front of it and measure the response in real time. Nobody runs an A/B test on their Domain Rating.
A search ranking is something Google lets you borrow. A subscriber list is something you own. Build your content strategy like you know the difference.
What this changes about how you build
None of this is an argument against SEO. Rankings still bring people who haven’t met you yet, and that discovery function matters. The argument is about where you point the value once they arrive. A blog post that ranks and converts a reader into a subscriber has done its job twice. A blog post that ranks and lets the reader leave without a way to find you again has done its job once, and the second half of that value belonged to whichever platform happened to send the click.
Every page that earns attention should be converting some of it into a list you own — not as an afterthought widget in the sidebar, but as a deliberate decision about which asset you’re actually building. The ranking is rented. The list is yours.
Does Google use Domain Rating or Domain Authority to rank websites?
No. Domain Rating (Ahrefs), Domain Authority (Moz), and Authority Score (Semrush) are third-party metrics built by SEO tool companies. Google has stated directly that it does not use these scores. They can correlate loosely with ranking potential, but they are not a Google ranking factor and cannot be transferred, sold, or controlled the way an owned asset can.
Why is an email subscriber list considered a business asset?
An email list is portable, exportable, and fully owned by the business that built it. Acquirers and investors treat list size, engagement rate, and list age as standard due-diligence metrics in deals involving content or media businesses, because the list represents a direct, measurable relationship with an audience that doesn’t depend on any platform’s algorithm.
How does a subscriber list compare in value to organic search traffic?
A subscriber list lets you measure direct response — you send a message and watch exactly how it performs. Organic traffic from a ranking is harder to value because the relationship between a metric like Domain Rating and actual qualified visits is inconsistent and can shift for reasons unrelated to anything the business did.
Should businesses stop investing in SEO in favor of email lists?
No. SEO still drives discovery and brings in people who haven’t encountered the business yet. The point is to treat every page that earns search attention as an opportunity to convert that attention into an owned asset — a subscriber — rather than letting the value of the visit disappear when the reader leaves.
