InternationalCountry code top-level domain
ccTLD
A top-level domain assigned to a country or territory, such as .de or .fr, which carries an inherent and unchangeable geo-targeting signal.
In full
ccTLDs are the strongest country-targeting signal and often carry local user trust, but they fragment authority across domains, multiply technical and operational overhead, and cannot be geo-targeted to a different country in Search Console. Some ccTLDs are treated as generic by Google because of their widespread non-geographic use — .co, .io and .tv among them. The choice is usually driven by brand and legal considerations as much as SEO.
Example
A retailer runs example.de and example.fr as separate ccTLDs, accepting duplicated technical work for stronger local trust.
