How domain appraisal works when comparable sales set the price
10 min read By the DomainAgent team
A domain appraisal estimates what a name is likely to sell for, and the most reliable way to build one is from comparable sales: real, public sales of names that share the target's extension, length, word count and commercial meaning. The result should be a range, adjusted for who is buying, not one exact number.
Buyers use that range to choose an opening offer and a ceiling. Sellers use it to set a floor and an asking price. Both sides make expensive mistakes when they trust a single figure without knowing where it came from. This guide explains how comparable sales work, how to choose and adjust them, and how to turn them into decisions.
Why a single automated number misleads
Automated valuation tools are quick and free, and that is their appeal. You paste a name and get one figure back. The trouble is that the figure hides everything that matters. You cannot see which sales it used, how old they were, or whether those sales were to investors or to companies that build on the name.
Two problems follow. First, a single number feels precise when it is only a guess with a wide margin around it. A name shown at 7,200 USD might realistically sell anywhere from 2,000 USD to 15,000 USD, and the tool does not tell you that. Second, the number ignores the buyer. The same name can be worth very little to another investor and a lot to the one company whose brand matches it exactly.
That does not make automated tools useless. They are a reasonable first filter when you scan many names. They are a poor basis for an offer you will actually send, or a price you will actually accept.
What a comparable sale is
A comparable sale, often called a comp, is a completed and publicly reported sale of a domain similar to the one you are valuing. Public sale reports, such as weekly published lists of notable sales, are the main source. Each record gives you a name, a price and a date, and sometimes the venue where it sold.
The idea comes from real estate. Nobody values a house by its own address alone. They look at what similar houses nearby sold for recently, then adjust for differences. Domains work the same way, except that the neighborhood is defined by extension, length, words and meaning instead of streets.
Comps have limits. Many private sales are never reported, and reported sales lean toward the higher end, because people like to publish good results. Keep that in mind and treat comps as evidence, not as a promise.
How to pick good comps
Picking comps is where most of the skill lies. A list of ten close matches is far more useful than a list of a hundred loose ones. Filter by the traits that move price the most.
Extension
Compare like with like. A .com sale says little about the value of the same word in another extension, and the reverse is also true. If you are valuing a .ai name, look first for .ai sales, then use .com sales only as a loose upper reference.
Length and word count
Shorter names usually sell for more, and one word names sit in a different band from two word names. Count characters and words, and keep your comps within the same group. A seven letter single word and a fourteen letter phrase are different products.
Keyword commerciality
Ask what kind of business would use the words. Terms tied to industries with high customer value, such as finance, insurance, software or health, tend to sell higher than words with no clear commercial use. A good comp has a similar commercial meaning, not just similar letters.
Date of sale
Markets move. A sale from last year tells you more than one from long ago, especially for extensions whose popularity has changed. Give recent sales more weight and drop very old ones unless nothing else exists.
Buyer type when you can tell
If a comp sold to a company that now uses the name, it reflects end user value. If it sold between investors at an auction, it reflects wholesale value. Mark each comp with what you know, because mixing the two hides the real range.
Adjusting comps to fit your name
No comp will be a perfect match, so you adjust. The goal is to move each comp's price up or down to reflect how your target differs. Keep adjustments simple and write down your reason for each one.
- If your name is shorter or easier to spell than the comp, adjust upward.
- If your name has a weaker commercial meaning, adjust downward.
- If the comp is old and the extension has grown in popularity since, adjust it toward today.
- If the comp sold to an end user and you are pricing a wholesale sale, adjust downward, and the reverse.
- If your name has a known flaw, such as a hyphen, an awkward plural or a common misspelling, adjust downward.
Here is a fully hypothetical example. Say you are valuing a two word .com in a business category. You find three close comps at 3,500 USD, 6,000 USD and 9,500 USD. The 9,500 USD sale was to a company that built on it, so you mark it as end user. The 3,500 USD sale was at an investor auction, so it is wholesale. The 6,000 USD sale is a private sale with an unknown buyer. You now see that the wholesale band sits lower and the end user band higher, and your range needs both ends.
Wholesale price versus end user price
This is the single most important split in domain appraisal. The same name has two realistic prices.
| Price type | Who pays it | Why the price is what it is |
|---|---|---|
| Wholesale | Another investor | The buyer needs room to resell for a profit, so they pay well below end user value |
| End user | A company that will use the name | The buyer values the name for its brand, traffic or trust, and compares it with the cost of building a brand elsewhere |
A seller who only ever hears from investors may think the name is worth the wholesale figure. A buyer who sees end user sales may think every similar name costs that much. Both are half right. When you appraise, say which price you are estimating. A seller looking for a fast sale to another investor uses the wholesale band. A seller who will spend time reaching companies uses the end user band. A startup buying its brand name usually pays something near the end user band, because the owner knows that.
Why the answer is a range, not a point
Once you have adjusted comps, you have a spread of prices. Resist the urge to average them into one figure. Instead, describe the spread in three parts.
- A low value, near the bottom of the adjusted wholesale comps.
- A likely value, where most adjusted comps cluster.
- A high value, near the top of the adjusted end user comps.
A range tells you how certain you are. A narrow range means many close comps agree. A wide range means the evidence is thin, and every decision you make should allow for that. It is honest to say that a name is likely worth 4,000 USD to 8,000 USD with a most likely value near 5,500 USD. It is not honest to say it is worth exactly 5,437 USD.
A domain appraisal from DomainAgent shows exactly this kind of range together with the comps behind it, so you can see why the numbers are where they are and challenge any comp that does not fit.
How buyers turn comps into an opening offer and a ceiling
For a buyer, the range does two jobs. The low end suggests where to open. The likely value and your own need for the name decide your ceiling.
Take the hypothetical range above, 4,000 USD to 8,000 USD with a likely value near 5,500 USD. A sensible opening offer might sit around 3,500 USD to 4,000 USD, low enough to leave room and close enough to the comps that the owner treats it as serious. Your ceiling depends on how much the name matters. If two other names would work almost as well, a ceiling near the likely value makes sense. If this name is your brand, you might accept a ceiling closer to the high end, but you decide it before you send anything.
If you are trying to buy a domain that is taken, the comps also give you a calm, factual way to explain your offer. Telling an owner that similar names sold in a certain range sounds very different from simply asking for a discount.
DomainAgent's Buy Agent pulls comps, estimates the range and proposes an opening offer and a walk-away price, which you can change before approving the band it negotiates inside. Any binding offer still needs your approval click.
How sellers turn comps into a floor and an asking price
For a seller, the range sets two numbers too. The floor is the lowest price you will accept. The asking price is what you show buyers first.
A floor near the wholesale end of the range makes sense if you want liquidity, or if the renewal cost of holding the name is starting to add up. A floor nearer the likely value makes sense if you can wait. The asking price usually sits at or above the high end of the range, because end users expect to negotiate and you need room to concede.
Using the same hypothetical numbers, a seller might set a floor of 4,500 USD and an asking price of 9,500 USD. Some buyers will offer far less. The comps let you answer them calmly, and the floor stops you from going below a number you chose with a clear head.
DomainAgent's Sell Agent negotiates down to your floor and never below it, and it asks for your approval before any acceptance.
Common appraisal mistakes
- Using comps from a different extension without adjusting for it.
- Mixing one word and two word names in the same set.
- Averaging wholesale and end user sales into one figure that fits neither.
- Relying on very old sales in a market that has changed.
- Treating asking prices on listings as if they were sales. An asking price is a hope, not a comp.
- Ignoring known flaws such as hyphens, numbers or hard spelling.
- Quoting one exact number with false precision.
- Forgetting that reported sales are a sample, and that the quiet, unreported sales are often lower.
A simple check catches most of these errors. For each comp in your final list, write one sentence explaining why it belongs there. If you cannot write that sentence, drop the comp.
A short checklist before you rely on an appraisal
- Do you have at least five comps in the same extension and word group?
- Is each comp marked as wholesale, end user or unknown?
- Have you adjusted each comp for length, meaning, date and flaws?
- Is your answer a range with a likely value, not one point?
- Have you turned the range into concrete numbers, an opening offer and ceiling if you are buying, a floor and asking price if you are selling?
If every answer is yes, your appraisal is ready to use. If not, the gap usually points to the next comp you need to find. A domain broker that runs on comps will show its evidence, and so should you.
