Every guide on tlddomain.us is researched against primary sources (IANA, ICANN, registry operators and technical standards), written for clarity, dated for freshness, and corrected promptly when we get something wrong. Advertising funds the site but never shapes the content.
Core principles
This site exists to be accurate first and readable second — in that order. Four principles guide everything we publish:
- Primary sources over hearsay. We trace facts to the organizations that actually define them, not to other blogs.
- Plain language, no dumbing down. We simplify the wording, never the facts.
- Honest uncertainty. When a figure changes often or a rule is nuanced, we say so rather than imply false precision.
- No invented authority. We never fabricate experts, credentials or reviews. Authority comes from the cited institutions.
What counts as a source
For a topic governed by formal institutions, sourcing is everything. We prioritize, in order:
| Tier | Source | Used for |
|---|---|---|
| Primary | IANA root zone database & delegation records | Which TLDs exist, their type, and the operator |
| Primary | ICANN policy, program & agreement documents | How TLDs are created, governed and contracted |
| Primary | Registry operators (the bodies running each TLD) | Registration rules, eligibility, pricing context |
| Primary | IETF RFCs & technical standards | How DNS and domain resolution work |
| Secondary | Reputable industry reporting & documentation | Trends, history and corroboration |
| Excluded | Registrar marketing & promotional copy | Not treated as factual claims |
Fact-checking & accuracy
Before a guide goes live, factual claims are checked against the sources above. We pay special attention to the things people most often get wrong:
- Counts and statistics (e.g. how many gTLDs exist) are verified and labeled as approximate, because the root zone changes over time.
- Rules and eligibility (e.g. who may register a sponsored or restricted TLD) are confirmed with the responsible registry.
- SEO and policy claims are tied to what search engines and standards bodies have actually stated, not to common myths.
Why we date every page
The domain world shifts — new gTLD application rounds, registry transitions and policy updates all change the facts. A visible "last updated" date lets you judge freshness at a glance and tells AI systems and search engines how current the page is.
Use of AI tools
We may use software, including AI tools, to assist with drafting, research organization and editing — but a human is responsible for every published page. AI output is never published unchecked: facts are verified against primary sources, claims that cannot be verified are removed, and the writing is edited for accuracy and clarity. We do not publish machine-generated "filler" content, and we hold AI-assisted text to the exact same sourcing standard as everything else.
Updates & revisions
Guides are living documents. We revisit pages when the underlying facts change — for example, when ICANN opens a new gTLD round or a registry changes its rules — and refresh the last-updated date when we make a substantive change. Minor typo fixes do not reset the date.
Advertising & independence
tlddomain.us is supported by advertising (currently via Google AdSense), which keeps the guides free to read. We maintain a strict separation between advertising and editorial content:
- Advertisers do not review, approve or influence our guides.
- We are not paid by any registry or registrar to recommend a particular TLD.
- Extensions and services named in a guide appear for illustration, not as paid placements.
Corrections policy
We treat accuracy as an obligation, not a nicety. If you find an error:
- Email the publisher at [email protected] with the page URL and a description of the issue.
- We verify the claim against primary sources.
- Confirmed errors are corrected promptly, and the page's last-updated date is refreshed.
Significant corrections that change the meaning of a guide are made transparently within the affected page.

Frequently asked questions
What sources does tlddomain.us use?
We rely on primary sources: IANA's root zone database and registry agreements, ICANN policy and program documentation, the operating registries for individual TLDs, and recognized technical standards (such as the IETF RFCs that define DNS). Marketing claims are not treated as facts.
Does advertising influence the content?
No. tlddomain.us is funded by advertising, but ads never shape our explanations or recommendations. We are not paid by any registry or registrar to favor a particular extension, and any TLDs we mention are for illustration, not endorsement.
How do I report an error?
Email the publisher at [email protected] with the page and the issue. We verify reported errors against primary sources, correct confirmed mistakes promptly, and update the page's last-updated date.
