TLD (Top-Level Domain)

The last segment of a domain name, appearing after the final dot.

A Top-Level Domain (TLD) is the rightmost part of a domain name. Common examples include .com, .org, .net, and country codes like .uk or .de.

Types of TLDs:

Generic TLDs (gTLDs):

  • .com - Commercial (most popular globally)
  • .org - Organizations (often non-profits)
  • .net - Network (originally for ISPs)
  • .info - Information sites
  • .biz - Business

Country Code TLDs (ccTLDs):

  • .uk - United Kingdom
  • .de - Germany
  • .jp - Japan
  • .io - British Indian Ocean Territory (popular with tech)
  • .ai - Anguilla (popular for AI companies)

New gTLDs (introduced since 2012):

  • .app - Applications
  • .dev - Developers
  • .tech - Technology
  • .store - E-commerce
  • .blog - Blogs

Each TLD has its own registry that manages it, and some have specific requirements or restrictions for registration.

Why It Matters

The TLD you choose affects how people perceive your website and can influence trust. A .com is universally recognized and trusted, while a .io signals tech-savviness. Some TLDs like .gov or .edu have strict requirements, adding credibility.

Practical Example

A startup might choose startup.io for its tech credibility, while an established law firm would likely prefer lawfirm.com for the professionalism and trust that .com conveys.
