Thousands of domains expire every day. A small fraction are genuinely worth owning, and the difference between the two is measurable rather than a matter of taste.

Age and continuity of history

An old domain with continuous, legitimate history carries more trust than a fresh registration. The key word is continuous: a domain registered in 2004 and abandoned in 2011 is not the same as one that has been live and maintained since 2004.

Check archived snapshots across the whole life of the domain, not just the most recent capture. What a domain was used for tells you more than how long it existed.

Backlink profile quality

  • Number of referring domains, not just total links
  • Anchor text that looks natural and varied
  • Referring sites that are real businesses rather than link networks
  • No sudden spikes that suggest a paid link campaign
  • No sharp drop that suggests a penalty

Fifty links from fifty real, relevant sites are worth more than five thousand links from a single network.

Name quality and brandability

  • Two real dictionary words beat invented strings
  • Short and easy to spell over the phone beats clever
  • Matches a commercial niche that actually buys
  • No confusing homophones or awkward double letters

Names that pass the phone test — someone hears it once and types it correctly — hold their value far better than clever ones.

Risk checks that disqualify a domain

  • Previously used for spam, malware or adult content
  • Contains a trademark you do not own
  • Deindexed or carrying a manual penalty
  • Sits behind a known toxic link network
  • Appears on a blacklist anywhere

Any one of these is usually enough to walk away, regardless of how attractive the metrics look.

A cheap domain with a clean history and a real niche is worth more than an expensive aged domain with a toxic profile.

Comparable sales tell you the price

A valuation without comparables is a guess. Look at recent sales of similar names in the same niche and extension, and work from those rather than from a tool number. Recent, real transactions beat any algorithm.
