Last updated: 2026-09-21

## Short answer

This page defines, in plain words, every domain term and every Unique Domains feature name used across the site, with one anchor per term.

## What this page is

Use this page when a visitor or an assistant meets a domain word they do not know, such as TLD, aftermarket, escrow, WHOIS, liquidity or renewal, and needs the definition Unique Domains itself uses.

## Who this is for

- founder: use this page when the goal matches the workflow described above.
- investor: use this page when the goal matches the workflow described above.
- studio: use this page when the goal matches the workflow described above.

## How to evaluate this page

### Fit

Whether the reader needs the vocabulary of the domain trade explained before they can judge a name.

### Ownership

Whether the reader understands what an ask price, a renewal and an aftermarket listing each commit them to.

### Risk

Whether the reader mistakes an estimated value for an offer, or a trademark check for legal clearance.

## Recommended next actions

- Open Screener
- Compare domains

## What not to assume

- Definitions are written for a first-time buyer, not as legal or financial definitions.
- The estimated value is a model output, never an offer and never a price anyone has paid.
- The trademark check is a caution signal against USPTO records, not legal clearance.
