Why Global Rankings Hide Regional Realities

A global ranking flattens key regional dynamics. For example, while WhatsApp leads globally, it is secondary in Thailand where LINE commands over 90% smartphone penetration. Similarly, South Korea operates on KakaoTalk, and China runs on WeChat. If your product is expanding internationally, regional market fit is critical.
