Country-code top-level domains, or ccTLDs, are two-letter domain extensions associated with individual countries. While ".com", ".net", and ".org" are widely used generic extensions, a website may choose a ccTLD to identify a country or region.
Extensions such as ".fr", ".de", and ".tr" can indicate where a website is registered or the region its content serves. In SEO, a ccTLD can help a site reach a target country or region because Google may treat the site or content as relevant to searches made there.
