Domain value and whois lookup

What is domain value and what determines it?

Domain value is an estimated monetary figure that helps a domain owner gauge what the name could sell for before putting it on the market. The estimate rests on four groups of data: authority scores, monthly organic traffic, link quality and the qualities of the name itself. The aftermarket for domain names became visible in the late 1990s; since then, publicly disclosed sales have ranged from a few thousand lira to tens of millions of dollars. The domain value calculator on this page reads all four groups from real provider data and gives the result in TL as a low-high range with an item-by-item breakdown.

For authority, Moz DA (Domain Authority) and Ahrefs DR (Domain Rating) are used; both score a site from 0-100 based on its link profile. Link quality is shown by the balance between Majestic's TF (Trust Flow) and CF (Citation Flow): if CF is high but TF is low, the links bring quantity, not trust. The traffic item represents the ad-equivalent value of monthly visits from ranking keywords. Name qualities (length, extension, hyphens and digits) enter the calculation as multipliers: of two names with the same metrics, the shorter one with a .com extension gets a higher range.

How do you check a domain's value?

Checking a domain's value on this page takes three steps; no payment and no setup.

1. Enter your domain with its extension in the card above (e.g. example.com) and click Calculate Value.
2. The tool pulls authority, traffic and link data from Moz, Ahrefs and Majestic and adds the name's qualities as multipliers.
3. The results screen shows the estimated value, the low-high range and a table of line items; you can read row by row how many TL each component adds to the estimate.

Your remaining queries appear in the counter below the form. An investor who wants to value several names can run the queries back to back and note the breakdowns side by side. The breakdown also points to strategy: a name with a weak traffic item gains value through content investment, and one with a weak authority item through link building.

What makes a domain name valuable?

Brevity, a .com extension and a clean spelling without hyphens are the three main qualities that raise a domain's value regardless of metrics. What they share is liquidity: names with these qualities attract a larger pool of buyers and sell faster.

• Length: short, one-word names are memorable; commercial generic words such as insurance, loans or hotel make up the most liquid segment of the market.
• Extension: .com commands a clear premium over other extensions of the same name; in the Turkish market, .com.tr is a strong second choice for corporate buyers.
• Spelling: hyphens and digits create ambiguity when the name is said out loud; names that can be spelled two ways get fewer offers.
• Age: names registered for a long time with a clean history give you leverage in negotiation; age alone does not set a price, but it counts when combined with a clean history.
• Brandability: names that are easy to pronounce and have a single spelling suit corporate use, which brings the strongest buyer profile to the table.

Brevity does not always create value: four-letter strings that cannot be pronounced sell far below real words of the same length. Turkish names have an extra limit: for words that do not appeal to global buyers, the pool is limited to local businesses, which narrows liquidity from the start.

What prices have the most valuable domains sold for?

Three well-known disclosed sales mark the top of the market:

• Business.com changed hands for $7.5 million in 1999, one of the first big sales to bring the domain aftermarket into mainstream news.
• In 2019 software company MicroStrategy sold Voice.com to blockchain startup Block.one for $30 million; the price was confirmed by both parties' announcements.
• HubSpot co-founder Dharmesh Shah bought Chat.com for $15.5 million in 2023; the name passed to OpenAI in November 2024, and the transfer price was not disclosed.

Public lists show the disclosed tip of the market, not the whole of it. Some big sales stay under confidentiality agreements; the undisclosed price in the Chat.com transfer is a recent example. The gap between outliers and ordinary sales is wide too: most names that change hands each year sell for modest sums, far from these figures.

Why do estimates and actual sale prices differ?

In the end, a domain is worth only what a buyer agrees to pay, while the figure from a domain value tool is the statistical equivalent of measurable signals. The two numbers often diverge because two forces the metrics do not measure are at work in a negotiation: buyer motivation and time.

Buyer motivation alone can change the picture: a company looking for a name that exactly matches its brand will pay many times the going rate, even for a domain with ordinary metrics. OpenAI's acquisition of Chat.com for its ChatGPT product is a well-known example; the name's appeal lay not in its scores but in its exact match with the product name. On the time side, liquidity is decisive: it can take months or even years for the right buyer to come along, and a seller who cannot wait cuts the price to shorten that time. The tool handles this uncertainty with a range instead of a single number: the low end represents a quick sale and the high end a patient wait.

How should you approach domain investing?

Approach domain investing with caution: the visible side of the field is outlier sales like Voice.com, and the hidden side is portfolios full of names that go years without a single offer. Investors who come out ahead earn their returns from a small number of well-chosen names; the rest of the portfolio is mostly an expense.

The cost side is clear: you pay an annual renewal fee for every name, and as the portfolio grows that expense builds up whether or not anything sells. The income side is unpredictable; there is no calendar telling you which name will find a buyer and when. Trending words carry extra risk: names bought at the peak of a wave of demand may not find a buyer even below the purchase price once the wave passes.

Names containing registered trademarks are a separate trap: the trademark owner can claim the name through UDRP, the arbitration process for domain disputes, and an investor who loses hands the name over for nothing. Risk also depends on your profile: an owner who bought a name for their own site and is thinking of selling it years later comes to the table with a measurable asset and a data-based price anchor. Collecting names purely to sell them is a business of its own that needs a separate budget, market knowledge and a lot of patience.

What do whois and DA PA lookups add to a value estimate?

The whois record adds the name's age and registration history, and a DA PA lookup adds detail on authority scores; together with the value tool, these three make up the minimum set of checks before a buy or sell decision.

In practice the order is: get the estimated range here first, then check the registration and expiry dates with the whois lookup tool; a name close to expiry that does not appear to have been renewed strengthens the buyer's hand. As a final step, verify the authority scores in detail with the DA PA Checker; if the authority item in the breakdown is higher than expected, you will see where it comes from there.

With cheap names that have high metrics, a practical reality comes into play: expired domains, dropped when their registration ran out, carry their old link profile for a while. If such a name with a strong-looking DR has spam content in its past, the new owner inherits not authority but a record that is hard to clean up. Checking the name's earlier versions in the Wayback Machine archive before buying largely avoids this trap.

What does a domain value check give you, and what can't it guarantee?

A value check gives you three concrete things: a data-based starting price for negotiation, a priority order showing which names in a portfolio are worth their renewal fee, and a reference breakdown to put on the table against low offers. The three things it cannot guarantee are just as clear: the price a sale will close at, how long a sale will take and whether the value will hold in the future. Practical use follows from this: an owner thinking of selling makes the high end the list price and keeps the low end as the negotiation floor, while an investor focuses on growing the weak item in the breakdown, which in most portfolios is traffic.
