Category-defining domain

Why it matters

These names carry the highest prices because one company can claim the category with them. They bring type-in traffic, trust, and a strong search signal. A buyer should check whether the market can pay for it, since the price must fit the company's customer value. Sellers should expect long talks and often a broker. Common mistake: calling any keyword name category-defining. A name qualifies only when it is the most natural word for the whole category, not a niche phrase.
