About tlddomain.us

Why this site exists

Domain extensions touch almost everyone who builds a website, starts a business, or simply wonders why some addresses end in .com and others in .io or .uk. Yet most explanations are either oversimplified ("just buy a .com") or buried in dense technical specifications written for engineers.

tlddomain.us sits in the middle. Our goal is to answer the real questions people ask — What is a TLD? Should I pick a country-code domain? Do extensions affect SEO? — in language a non-specialist can understand, while staying faithful to how the domain name system actually works.

What we cover

This is the concepts and how-to side of domains. We focus on explainers, comparisons and practical guidance rather than a giant lookup table of every extension. Our core topics include:

• Foundations — what a TLD is, the parts of a domain name, and the DNS hierarchy.
• Comparisons — gTLD vs ccTLD, legacy vs new gTLDs, and how categories differ.
• How-to guides — choosing the right extension and registering a domain step by step.
• Strategy — the real (and overstated) effects of TLDs on SEO, trust and branding.
• Context — the history of domain extensions and the organizations that govern them.

Who writes tlddomain.us

This site is operated by Mustafa Bilgic, an independent web publisher who builds and maintains practical reference resources. Mustafa researches each topic against primary documentation and writes in plain English so the material is useful to beginners and professionals alike.

We deliberately do not invent fictional "experts" or fabricate credentials. Where authority matters, we cite the institutions that actually set the rules — ICANN, IANA, registry operators and recognized technical standards — so you can verify any claim at its source.

How we research

Accuracy is the entire point of a reference site, so every guide follows the same process:

• Start from primary sources. Definitions, categories and counts come from IANA's root zone database, ICANN policy documents and the registries that operate each TLD.
• Verify before we publish. Numbers (such as how many gTLDs exist) and rules (such as who can register a sponsored TLD) are checked against current documentation, and we describe figures as approximate when they change frequently.
• Date everything. Each guide shows a visible "last updated" date so you know how fresh it is.
• Revisit regularly. The domain landscape evolves — new gTLD rounds, registry changes, policy updates — and we update pages as facts change.

Our full standards are documented in our editorial policy.

Editorial independence & funding

tlddomain.us is funded by advertising, which keeps every guide free to read. Advertising never influences our explanations or recommendations: we describe extensions on their merits, and we are not paid by any registry or registrar to favor a particular TLD. Where we mention specific extensions or services, it is for illustration, not endorsement.
