How we score domains

Booted.io, the FreedDomains .io mascot: a teal cartoon .io domain extension with two big eyes and a wide smile, waving with both hands

Every name on FreedDomains gets four scores of our own, calculated from the name itself and from the checks we run on it. They help you sort tens of thousands of names quickly. They are estimates, not appraisals: always check a name yourself before you buy.

Quality score (0 to 100)

The quality score is the main ranking on top picks, the daily briefing and the "Best first" sort on every list. Higher is better. It adds up:

Checks fill in over time, best names first, so a name's score can rise as its history and authority are measured. A name with no history yet is not penalised for it.

Brandability (0 to 100)

How well a name would work as a brand: about six letters long, easy to say (a natural mix of vowels and consonants, no clusters of four consonants or three vowels), with no numbers or hyphens. One or two real words get a small bonus. Made-up names such as CVCV patterns often score well here even though they score lower on quality.

Radio test

A name passes when it is one or two dictionary words, has no numbers or hyphens and is twelve letters or fewer: you could say it once on the radio and listeners would type it correctly. Filter for it with Passes the radio test under More filters.

Fair value (£)

A rough guide to what a name might sell for between investors, from its quality score and extension. Use it to decide how far to go in an auction, not as a price: real sales depend on the buyer, the keyword's search demand and comparable sales, which we do not have for every name. A .com of the same quality is valued highest; country and newer extensions lower.

How to use the scores

  1. Sort any list by Best first, or set a minimum quality score under More filters.
  2. Look for names with a high quality score and a low spam score; then open the domain checker for the registry status and history.
  3. For a new brand, sort by Most brandable or tick Passes the radio test.
  4. Before bidding, compare our fair value with what similar names have sold for at the auction houses.
