ccTLD(国コードトップレベルドメイン)
A ccTLD (Country Code Top-Level Domain) is a domain extension reserved for a specific country or sovereign territory, such as .fr (France), .de (Germany), or .jp (Japan). It acts as the strongest possible geotargeting signal to search engines that the website is intended for that specific region.
The Ultimate Geotargeting Signal
Using a ccTLD gives you an immediate ranking boost in that country, but comes with significant infrastructure costs. You must maintain separate domains, split your SEO authority, and manage independent hosting for every country. For example, Amazon uses amazon.com (Global), amazon.co.uk (UK), amazon.de (Germany) to dominate local markets. This strategy works for enterprise brands with dedicated regional teams but is impractical for most businesses. The alternative (subdirectories like site.com/fr) consolidates authority on one domain while still achieving strong international rankings through proper hreflang implementation.
