## What is a domain extension (TLD)?

A domain extension, or TLD (top-level domain), is the label after the final dot — such as .com, .org, .ai, or a country code like .uk. DomainDiscovery’s extensions browser helps you explore 1,600+ options before you run domain name search and register at a registrar.

## Direct answer: Does a keyword TLD improve SEO by itself?
No. Helpful content and technical quality matter far more than the extension string alone.
