TLD
A top-level domain (TLD) is the last, rightmost segment of a domain name, such as .com, .org, or .kr. TLDs fall into two broad groups based on purpose: generic top-level domains (gTLDs) and country-code top-level domains (ccTLDs).
- A TLD is the top-level (rightmost) segment of a domain name; in example.com, the .com is the TLD.
- TLDs split mainly into generic domains like .com and .org (gTLDs) and country-code domains like .kr and .de (ccTLDs).
- A ccTLD acts as a strong geographic signal that a site targets a specific country, giving it an edge in local SEO for that market.
- According to Google, neither new gTLDs nor keywords contained in a TLD confer any ranking advantage or penalty in search.
- Google treats 24 ccTLDs such as .tv, .me, and .io as generic domains (gTLDs), so they receive no automatic geotargeting.
Overview
A top-level domain (TLD) is the final segment at the highest level of the domain name hierarchy. In www.example.com, for instance, the rightmost label, .com, is the TLD. Every domain name ends in exactly one TLD, and the global list of TLDs is maintained in the root zone databases of ICANN and IANA. As of February 2026, the IANA root database listed 1,593 registered TLDs.
TLDs are divided by purpose into generic top-level domains (gTLDs) and country-code top-level domains (ccTLDs). Most TLDs of three or more characters are classified as generic, with .com, .net, and .org being the most prominent examples. Two-character TLDs are country-code domains assigned to more than 250 countries and territories, such as .kr (South Korea), .de (Germany), and .jp (Japan).
Main Types
| Type | Form | Examples | Characteristics |
|---|---|---|---|
| gTLD (generic top-level domain) | 3+ characters | .com, .org, .net, .shop, .app | Purpose- or topic-based, no country restriction |
| ccTLD (country-code top-level domain) | 2 characters | .kr, .de, .jp, .cn, .uk | Tied to a specific country or region |
| New gTLD | Varies | .london, .blog, .ai, etc. | Expanded since 2013, treated as gTLDs |
| Generically treated ccTLD | 2 characters | .tv, .me, .io, .co | ccTLD in form, but handled as a gTLD by Google |
SEO Impact
How a TLD choice affects search performance depends on the type of domain. The key point is that a ccTLD works as a geographic signal, whereas new gTLDs and keywords embedded in a TLD provide no ranking benefit.
ccTLDs as Geographic Signals
Google treats country-code domains as explicit geographic indicators. Google Search Central documentation explains that a ccTLD is "associated with a specific country (for example, .de for Germany or .cn for China)," giving both users and search engines a strong signal that the site is clearly aimed at that country. As a result, using a ccTLD like .kr automatically works in your favor for local SEO in that market.
That said, Google handles 24 ccTLDs, including .tv, .me, .io, and .co, as gTLDs, because users and site operators tend to perceive them as serving general purposes rather than country targeting. In these cases no automatic geotargeting applies, so you must specify country targeting through separate means such as hreflang tags or a subdirectory structure.
New gTLDs Offer No Ranking Advantage
In a 2015 Google Search Central blog post outlining its handling of new gTLDs, Google stated that its systems treat new gTLDs the same as established gTLDs like .com and .org, and that "keywords in a TLD do not give any advantage or disadvantage in search." Geographic and city TLDs such as .london are likewise classified as gTLDs rather than ccTLDs. In other words, using a keyword-style new domain like .shop or .blog will not lift your rankings for that keyword.
Implementation Checklist
- If you are clearly targeting a single country, choose the corresponding ccTLD (for example, .kr for the Korean market) to secure the geographic signal.
- If you target multiple countries or languages, consider a structure that pairs a gTLD like .com with subdirectories (/kr/, /de/) and hreflang.
- If you use a generically treated ccTLD such as .io, .co, or .me, specify your target regions with hreflang, since there is no automatic geotargeting.
- Do not expect a ranking boost simply because a keyword appears in the TLD; choose a TLD on the basis of brand, trust, and memorability.
