GoDaddy domain appraisal alternative: a value estimate on every name you can still register
GoDaddy Domain Appraisal, the tool GoDaddy calls GoValue, is free, needs no payment, and is trained on more aftermarket sales data than any competing model has access to. GoDaddy published a benchmark in which GoValue beat both Estibot and two experienced human appraisers at predicting the prices of 2,000 held-out Afternic sales. The reason people still look for a GoDaddy domain appraisal alternative is not that the number is bad, it is that the number arrives on its own, attached to a name somebody already owns. NameBest puts the estimate on the other side of the problem: it generates names from a brief, confirms against the registry which of them nobody holds, and labels each free one with a value estimate, so the number tells you whether a name is worth the registration fee rather than what a stranger might want for it. Treat every automated figure, ours included, as an estimate rather than a promise of what a name will sell for.

GoDaddy Domain Appraisal against NameBest.
Written to be fair. Where they are better, the row says so.
| What matters | NameBest | GoDaddy Domain Appraisal |
|---|---|---|
| Price of the appraisal | Included in every paid plan; the registration fee is paid separately to your own registrar | Free to run, with no payment required |
| Depth of comparable sales data | Smaller sales record than GoDaddy holds, and we say so plainly | The largest aftermarket sales dataset in the industry, and the model is trained on it |
| Published accuracy benchmark | None published; we treat the appraisal as decision support, not a proven price | Yes, GoDaddy published a 2,000-sale holdout test against Estibot and two human experts |
| What the estimate is attached to | A generated name the registry says is still free, so the number sorts a shortlist | A name somebody already owns, so the number frames an offer |
| Bulk portfolio appraisal and API | Not offered: appraisal runs one result at a time inside the search | Yes, bulk valuation and programmatic access are available through GoDaddy |
| Name generation built in | Yes: the estimate exists to rank names the console just generated and checked | Separate from the appraisal tool |
| Best for | Deciding which of the free names you just generated is worth the registration fee | Scoring names you already own, especially at portfolio scale, for free |
What GoDaddy Domain Appraisal is, in GoDaddy's own published terms
GoDaddy is unusually open about how its valuation model works, which makes it possible to describe it accurately rather than guess. Every figure below comes from GoDaddy's own technical write-up of GoValue and its appraisal tool documentation.
| What it is | GoDaddy figure | What to know |
|---|---|---|
| What it costs to run | Free | GoDaddy states it provides GoValue for free in order to expand the domain investing community and make buying and selling easier |
| When it launched | 2017 | GoDaddy's first automated valuation attempt shipped in 2012, and GoDaddy's own write-up says that system had underwhelming performance and was not well received |
| What the model is | A deep learning model, not a formula | The name is tokenized into words and fed through a recurrent neural network, then into a fully connected network that handles sale context and domain-level features |
| What feeds the score | Words, characters, extension, length, sale venue | Features include dictionaries spanning six languages and external sources such as Wikipedia to detect places, people and things; GoDaddy also notes names under 15 characters carry greater value |
| Venue adjustment | Almost 300 sale contexts | The model can output a different prediction depending on where a sale would happen, which is why the same name scores differently for an auction than for a reseller network |
Sourced from GoDaddy's published material on GoValue and its domain appraisal tool, read September 2026. This is competitor research to help you judge an appraisal figure, not a price comparison: GoDaddy's appraisal is free, and NameBest does not sell appraisals separately either. Automated valuation models are retrained over time, so treat the technical detail as a description of the approach rather than of today's exact weights.

GoDaddy built the best-funded automated appraisal in the business and then gave it away. GoValue reads a domain the way a valuer reads a property: it tokenizes the name into words, scores the keywords, weighs the extension and the length, and compares the result against comparable sales pulled from the largest aftermarket dataset anyone holds. For a generic keyword .com with a long public sales history it is genuinely good, and it costs nothing.
The gap is which question it answers. GoValue prices a name that already has an owner, which is the aftermarket question. NameBest asks the earlier one: of the names nobody has taken yet, which are worth taking. Every candidate the console generates is put to the registry through RDAP, and every free one comes back with a labelled value estimate beside it, which is what turns forty available names into a shortlist of six. Our honest limit, stated plainly: GoDaddy sees more sales than we do, so on raw comparable data they have the advantage, and no automated number from either of us is a guarantee. NameBest also sells nothing, so there is no transaction here for the estimate to sit next to.
How accurate is GoDaddy domain appraisal?
GoDaddy domain appraisal is most accurate on short, generic, keyword .com names that resemble many domains already sold in public. It is least accurate on brandable invented names, newer extensions, and names whose value comes from something the model cannot see, such as an existing audience or a trend that has not produced sales yet. Accuracy is a function of how much comparable data exists, not of how confident the number looks.
GoDaddy has published its own evidence, which is more than most valuation tools do. In a technical post on the model, GoDaddy describes asking two industry experts with years of experience to predict sale prices for 2,000 Afternic sales from late 2017, held out of the training data, and comparing them against GoValue and against Estibot. GoDaddy reports that GoValue was significantly better than both the human experts and Estibot on root mean squared error, and better than the human experts again on a second metric it calls rank score, the probability that two randomly chosen sales get put in the correct order of higher and lower price.
Read that benchmark for what it is. It measures the ability to predict prices that had already happened, on one marketplace, in one period, nearly a decade ago. It does not measure whether your name will find a buyer, and GoDaddy makes no such claim. The practical reading is that the ranking is trustworthy and the absolute dollar figure is a starting point, which is exactly how experienced investors use it.
Our position is the same and we will not pretend otherwise. The appraisal NameBest attaches to a result is decision support, it is an estimate rather than a guarantee of sale or resale value, and on breadth of comparable sales data GoDaddy is ahead of us. What we change is the distance between the estimate and the transaction.
Is GoDaddy domain appraisal free?
Yes. GoDaddy Domain Appraisal is free to run, and GoDaddy says so directly, writing that in building GoValue and providing it for free it hoped to expand the domain investing community by making it easier to buy and sell domain names. You type a name, you get a value with comparable sales, and GoDaddy also lets you email or download and print the report.
The commercial logic is easy to see and it is not sinister. A free valuation puts a number in front of someone who owns a name, and the two obvious next steps from that number are to list the name on GoDaddy Auctions or Afternic, or to renew it. Both of those are GoDaddy products. It is a good tool that also happens to be an excellent funnel.
NameBest has no free plan and we are not going to dress that up. What you pay for is the name itself, at its registration, listed, or winning bid price. The search, the AI appraisal and the name generator come with the account rather than as separate purchases, so there is no upsell sitting between the valuation and the buy button.
What GoDaddy's own numbers say about asking prices
The single most useful thing GoDaddy has published about domain valuation is not the model, it is a table of what its own top sellers were asking. In the same technical post, GoDaddy listed the average ask price of ten of its largest 2017 sellers alongside a portfolio quality score, a normalized version of the predicted GoValue for that seller's inventory. The spread is the lesson.
The top seller averaged $29,157 per listing. The tenth averaged $349. GoDaddy's own summary is that average ask prices vary by almost two orders of magnitude between different large sellers, and that this is a difference in strategy rather than a difference in name quality: some sellers price high and make fewer, larger sales, others price low and sell on volume.
Divide ask price by portfolio quality and the strategies separate even more clearly. Seller 6 asked $2,000 on a portfolio scored at 0.66, which works out to $3,026 per unit of quality, more than Seller 4 charged at $2,360 on a materially better portfolio scored 1.07. Two sellers holding comparable inventory were pricing it three times apart.
This is why any single appraisal number, from GoDaddy or from us, is a starting point rather than an answer. GoDaddy also notes that its model has to account for the venue: it reports GoDaddy Auctions, used mostly by domain investors, averaging $170 per sale, while the Afternic reseller network averaged over $1,500, and says these differences in sale context can account for more of the price difference than the names themselves. Much of that auction inventory is expired names dropping out of registration, which is a different market from a curated reseller listing. The same name is worth different money in different rooms. Before you accept or reject an offer, it pays to work out what a realistic offer looks like for your name and your venue.
Does GoDaddy have a bulk domain appraisal or an appraisal API?
GoDaddy has offered programmatic access to GoValue through its developer platform, and bulk valuation across a portfolio is a normal part of how large sellers use it, which is precisely what the published seller table above is built from. If you hold hundreds of names and want them scored in one pass, that capability is the strongest argument for staying with GoDaddy.
We will be straight about our surface here, because it matters for anyone comparing on features. NameBest appraises names one result at a time inside the search. We do not offer a bulk appraisal upload or a public availability API, and we are not going to imply we do. If bulk scoring across a large portfolio is your core workflow, that is a real reason to keep using GoDaddy for it.
Where we are useful to an investor is earlier than that. NameBest holds no portfolio and transacts nothing; it generates candidates at volume against a theme, filters them to what the registry says is unregistered, and puts a labelled value estimate on each, which is the part that decides whether a name is worth the registration fee in the first place. If you are actively building a portfolio rather than scoring one, that combination does more work, and it is the same view you want when you are deciding which names coming up for renewal are worth paying for again.
GoDaddy domain appraisal not working, or the number looks wrong?
Two different problems get reported the same way. The first is the tool refusing to return a figure, which usually happens on names it has almost no comparable data for: brand-new extensions, very long names, hyphenated or numeric strings, and internationalized names. There is nothing to fix there, the model is declining to guess and that is the correct behaviour.
The second is a number that comes back and looks obviously wrong. The two classic failure directions are well documented by investors and consistent with how the model is built: automated appraisals tend to overvalue weak names that superficially resemble sold ones, and undervalue genuinely brandable names that do not look like anything in the sales record. A one-word invented brand with no comparables will read low almost every time. The same blind spot shows up wherever scarcity rather than search volume drives the price, which is why a genuinely premium domain often scores below what it eventually sells for.
The fix is not another automated number, it is a second opinion of a different kind. Pull real comparable sales yourself, take five to fifteen of them, weight the last twelve to twenty-four months most heavily, and read the range rather than the mean. Never use asking prices on unsold listings as comparables, because an unsold ask proves only what somebody hoped for.
GoDaddy domain appraisal vs other sites: which domain appraisal tool should you use?
For a free score on a keyword .com you already own, GoDaddy is still the default and there is no shame in using it. Estibot is the long-running independent alternative and predates GoValue, though GoDaddy's own published benchmark put it behind. NameBio is not an appraisal tool at all, it is a searchable record of reported sales, and for anyone doing serious valuation work it is arguably more useful than any estimator because it gives you the raw comparables to judge for yourself.
The useful way to choose is by what you are about to do. If you are scoring a large portfolio you already own, use the tool with the deepest data and the bulk workflow. If you are researching one specific high-value name, go to the sales record and read comparables directly. If you are trying to decide whether to buy, bid or walk away on a name right now, use a tool that shows you the estimate and the availability in the same place, because that is the decision you are actually making.
That last case is the one NameBest is built for, from the other direction. Run a brief through the console and you get names the registry has no record of, each with a labelled value estimate beside it, which is the cheapest possible version of the buy-or-walk-away decision: you walk away from the negotiation entirely and register something nobody owns.
Who each tool is genuinely better for
No single valuation tool wins every case, and a comparison page that claims otherwise is not worth reading. If you have not settled on a name at all yet it is a different job again: generate brandable names first, then value the ones that survive. Here is the honest split, written the way we would tell a friend.
- Stay with GoDaddy Domain Appraisal if you want a free number, you hold a large portfolio you need scored in bulk, or your names are generic keyword .com domains with deep sales history.
- Use a sales database directly if you are valuing one name above roughly $5,000, where reading the actual comparable range beats any single estimate.
- Bring in a human broker if the name is category-defining, if an automated figure looks implausible in either direction, or if a live negotiation is already underway. NameBest runs no sell-side brokerage: the Brokerage plan is buy-side only, meaning we approach a holder on your behalf and never represent a seller.
- Use NameBest if the decision is still open: it generates names, proves against the registry which of them nobody holds, and puts the estimate on those, which is a cheaper decision than any of the ones above.
What changes when the check comes first
An estimate on every free name
Every row the console returns carries a labelled value estimate beside the registry verdict, so a list of available names arrives already sorted. It is guidance, not a price.
The question asked at the right moment
An estimate is most useful before you commit, not after. It arrives while the name is still unregistered and the decision is still yours to make cheaply.
Honest about the limits
GoDaddy sees more sales data than we do and publishes a benchmark we cannot match. We do not offer bulk appraisal or a public API, and we sell no domains at all, so nothing here is a venue you can transact on. We would rather say so than imply otherwise.
GoDaddy Domain Appraisal and NameBest, answered
General questions about the product are on the FAQ.
It is reasonably accurate on generic keyword .com names with plenty of comparable sales, and much less reliable on brandable invented names and newer extensions where comparables barely exist. GoDaddy published a benchmark showing GoValue beat Estibot and two human experts at predicting 2,000 held-out Afternic sales, but that measures ranking past prices, not whether your name will sell.
Yes, it is free to run and requires no payment. GoDaddy states plainly that it provides GoValue for free to make buying and selling domains easier. NameBest has no free plan: you pay for the console from $39 a month, and the value estimate comes with it rather than as a separate purchase.
GoValue is the name of the machine learning model behind GoDaddy Domain Appraisal. GoDaddy released it in 2017, after an earlier 2012 attempt that GoDaddy itself describes as underwhelming, and it uses a recurrent neural network over the words in a domain plus features for extension, length and sale venue.
Almost always because the model has few comparable sales that resemble your name. Automated appraisals systematically undervalue brandable invented names, which by definition do not look like anything already sold, and they lean low on newer extensions. Pull five to fifteen real comparable sales and read the range before you accept the figure.
Yes. Bulk valuation across a portfolio and programmatic access to GoValue are available through GoDaddy, and that is a genuine reason to keep using it if you hold hundreds of names. NameBest estimates one name at a time inside the console and does not offer a bulk upload or a public API.
If no figure comes back at all, the model usually has too little comparable data, which is common on new extensions, very long names, and hyphenated or numeric strings. If a figure returns but looks wrong, treat it as one input and check real comparable sales rather than reaching for a second automated estimate.
We do not claim that, and we would not be able to prove it. GoDaddy has more aftermarket sales data than we do and has published a benchmark; we have not. What NameBest changes is when the estimate arrives: on a name the registry says is still free, while taking it is still a $12 decision rather than a negotiation.
Automated appraisals from the major tools are typically free, so paying for a basic estimate rarely makes sense. Money is worth spending on human valuation only at the top of the market, where a broker's read on a category-defining name can move the price by more than the fee. NameBest does not sell valuations and runs no sell-side brokerage.
That is one of the most practical uses of any valuation tool. Running an appraisal across names coming up for renewal tells you which ones justify another year of registration cost and which are worth letting go. Read the estimate as a ranking signal rather than a price tag.
