What a Domain Appraisal Can and Can't Tell You
You have found a domain you like. Before you pay for it, you paste it into a free appraisal tool and get a number. Then you try a second tool and get a very different number. Which one is right?
Usually neither, at least not in the way you hoped. An appraisal is an estimate of what a domain might sell for in a market that is thin, private and uneven. It is useful, but it answers a narrower question than "what is this name worth to me?" This guide explains what the three common ways of valuing a domain actually measure, why they disagree, and how to use them together.
Three different questions
When people say a domain is "worth" something, they usually mean one of three things:
What does a model predict it would sell for? That is an automated appraisal.
What have similar names actually sold for? That is a comparable-sales check.
What is it worth to my business? That is the buyer's own value, and only you can calculate it.
These are not three attempts at the same answer. They are three different answers, and a sensible decision uses all of them.
How automated appraisals work
Automated tools are trained on past sales and score a name on its features. The major ones are fairly open about this.
GoDaddy describes its GoValue model as machine learning trained on over 65 million unique data points, including GoDaddy and Afternic domain transactions. Its own explainer says the tool uses proprietary machine learning and real market sales data, weighs factors such as length, keywords, keyword popularity and extension, and works much as appraisal tools in other industries do. The same page also says it is still prudent to do your own analysis before deciding what any domain is worth.
Atom, the marketplace where Rovaryn's domain sales complete, runs its own appraisal tool. Atom's CEO has described two separate outputs: an appraised value, and a Domain Score that reflects "the overall quality of the asset from an investor's perspective", covering brandability, memorability, versatility, commercial appeal and long-term potential. For very valuable names, Atom lists them as "over $1 million" rather than giving a precise figure.
That second output tells you something useful. Even the people who build these tools separate "how good is this name?" from "what will it fetch?" A name can score well and still be valued modestly, or the reverse, depending on what the market is currently paying for that kind of name.
Why appraisals disagree
In a June 2026 review of more than a dozen appraisal tools, Domain Name Wire concluded that the valuation of your domain "depends greatly on where you get it appraised". It found GoDaddy tended to come in on the low side and Appraise.net on the high side, and that some newer tools gave inconsistent answers for the same name.
There are a few structural reasons for this.
The training data is incomplete. Many domain sales are never published. GoDaddy has said that releasing more sales data involves working through issues such as SEC compliance and NDA agreements on sales. A model can only learn from the sales it can see, and the most valuable private deals are often the ones kept quiet.
Each tool sees a different slice. A marketplace's model leans on that marketplace's own transactions. Two tools trained on different sales histories will price the same name differently, and neither is wrong by its own data.
Markets move by extension and by trend. A model reflects what was selling when its data was gathered. Domain Name Wire's review of Atom's appraisals gave an example: a .ai name its author had sold for $8,000 was appraised by Atom at $34,000. A hot extension or category can pull estimates away from what any one name actually sells for.
Domains are not interchangeable. Two houses on the same street are close substitutes. Two two-word .com names in the same industry may not be. A model has to treat names as bundles of features, and the feature that matters most to one buyer may not register at all.
None of this makes appraisals useless. It means you should read them as a rough band, not a price tag.
What actually drives a domain's value
Across the tools' own descriptions, the same handful of factors keep coming up.
Length. Shorter names are easier to say, type and remember, and GoDaddy's explainer notes that shorter domains rank higher in its valuations. Very short names, such as three or four characters, are a market of their own.
Extension. GoDaddy lists the extension as a factor in its model, and Atom's appraised value accounts for it explicitly. The same word on a different extension can appraise very differently.
The words themselves. Real dictionary words, common phrases and clean two-word combinations tend to value higher than awkward strings. Brandable coined names, invented words that are short and pronounceable, are valued mainly on how they sound and how flexible they are.
Commercial intent. A name that describes something people pay for, such as a service, a product category or a business function, has a clearer pool of likely buyers. That pool is a large part of what a sale price reflects.
One factor people often overrate is search ranking. Google's own SEO Starter Guide says that keywords in the domain name alone "have hardly any effect" on ranking beyond appearing in breadcrumbs, and advises choosing a name that makes sense for your business. A descriptive domain can still help people understand and remember what you do. Just do not pay extra expecting it to rank you higher.
Comparable sales: the closest thing to evidence
A comparable-sales check asks what names with similar features actually sold for. Databases of reported sales, such as NameBio, let you filter by extension, length, keyword and price.
Comparables are evidence in a way an appraisal is not, because each one is a real transaction. They have limits too:
They are only reported sales. As noted above, many deals are private, so the visible record leans toward sales someone chose to publish.
"Similar" is a judgement call. A name with the same word count and extension may have a far weaker or stronger meaning.
They age. A sale from several years ago reflects that year's market.
The practical approach is to find a handful of genuinely close comparables and look at the range, rather than anchoring on one headline sale.
The buyer's own value
The third number is the one no tool can produce: what the name is worth to you.
A worked example, labelled as an illustration with round numbers. Say you are launching a B2B product and expect each customer to be worth a few thousand dollars over their lifetime. If a clearer, more memorable name meant you closed just a few more deals over the years, or spent less explaining who you are, a name costing a few thousand dollars could pay for itself. If you are naming a side project that may never earn anything, the same price is hard to justify, whatever an appraisal says.
Things worth weighing:
How long you will use it. A name you will build on for a decade spreads its cost over a long time.
What a weaker name costs you. Misspellings, confusion with competitors and names that are hard to say aloud all have real costs, even if they are hard to measure.
Rebranding later. Changing your name after launch means new signage, emails, links and marketing material, plus the effort of telling customers.
Trademark fit. Before you commit, check whether anyone already uses a similar mark in your field. That is a legal question, and this article is not legal advice.

How to use an appraisal well
Putting it together, here is a reasonable sequence:
Run two or three tools. Treat the spread as the signal. A narrow spread suggests the features are easy to price; a wide one suggests the models are guessing.
Check comparables. Look for several reported sales of genuinely similar names, recent if possible.
Work out your own value. Use your own numbers: what the name helps you earn or save over the years you will use it.
Compare against the asking price. A fixed listed price is a seller's decision, not an appraisal. Your job is to decide whether it sits below your own value.
An appraisal is a starting point for that thinking. It is not a guarantee of resale value, and nobody can promise what any particular name will sell for later.
How this applies to Rovaryn's domains
Rovaryn lists premium domains, each with a fixed listed price on its own page. Those prices are our asking prices, not appraisals, and we make no claim about what any name would fetch elsewhere. The portfolio spans short brandable names such as Klarv.com ($17,999) and descriptive business names such as ClaimsMgmt.com ($7,999) and IntakeManagement.com ($4,734). Those are different kinds of names, and they deserve the comparison steps above for different reasons.
There is no make-offer button. Purchases complete on Atom.com, with payment plus an escrow-backed, guided transfer that typically takes 1 to 3 days, and lease-to-own and payment plans are available there. If you want to ask about a specific name before you decide, get in touch.
