# TLD

> A TLD (Top-Level Domain) is the highest segment of a domain name — the part after the last dot, such as .com, .org or .pl — that identifies the branch of the DNS an address belongs to.

A **TLD** (Top-Level Domain) is the highest, final segment of a domain name — the part that appears after the last dot in an address. In the domain *nodea.pl* the TLD is *.pl*; in *example.com* it is *.com*. A TLD marks a branch in the hierarchical structure of the [Domain Name System](https://nodea.io/en/glossary/dns) and determines which set of name servers is responsible for a given ending.

## How a TLD works

The domain name system has a tree structure. At its top sits an invisible root dot, below it the top-level domains, then second-level domains (such as *nodea* in *nodea.pl*), and lower still the [subdomains](https://nodea.io/en/glossary/subdomain). Each TLD is governed by a dedicated registry — for example, the *.pl* domain is managed by NASK. When a browser resolves an address, the query travels from the root servers, through the servers responsible for that TLD, down to the domain's own [NS records](https://nodea.io/en/glossary/ns-record). The main TLD types are: **gTLD** — generic domains (.com, .org, .net); **ccTLD** — two-letter country codes (.pl, .de, .fr); **new gTLDs** — thematic endings introduced since 2013 (.shop, .app, .blog); and **sTLD** — sponsored, restricted-access domains (.gov, .edu).

## Practical application

Choosing a TLD is one of the first decisions when setting up a site. A country ending like *.pl* builds trust among a local audience and supports [local SEO](https://nodea.io/en/glossary/local-seo), while *.com* suits projects with a global reach. New thematic TLDs let you build a shorter, more descriptive address when your preferred name is already taken under the popular endings. You can look up a domain's owner and registry in the [WHOIS](https://nodea.io/en/glossary/whois) database. After registration and delegation setup, you still have to wait for [DNS propagation](https://nodea.io/en/glossary/dns-propagation) before the address works across the whole internet.

### What is the difference between a gTLD and a ccTLD?

A gTLD (generic TLD) is a generic, country-neutral domain such as .com, .org, .net or .shop. A ccTLD (country-code TLD) is a two-letter domain assigned to a country under the ISO standard — .pl for Poland, .de for Germany, .uk for the United Kingdom. The choice depends on reach and target audience.

### Does the choice of TLD affect SEO?

The ending itself is not a direct ranking factor, but a country-code ccTLD (such as .pl) sends the search engine a clear geolocation signal, which helps with local SEO. A .com domain is geographically neutral and works better for an international reach.
