A generated list is only the first draft. Validation turns it into a shortlist that a team can discuss with confidence. The goal is to remove weak names quickly and give the strongest names enough context for a real decision.
Use a four-pass review
First, remove names that are too long or confusing. Second, check whether the name matches the target audience. Third, compare TLD options. Fourth, use market data to see whether the category has visible activity.
Bring in external evidence
NewDomainData fits the fourth pass because it can show fresh registrations, TLD momentum, and related naming patterns. That does not replace legal or availability checks, but it gives the shortlist a stronger research foundation.
By the end, each remaining domain should have a reason to exist beyond “it sounded good during brainstorming”.
