Language Detection
IP-based Detection
Okay

Detecting the language by the user's location is not ideal. For example, you're visting Germany, but do not speak German, the language will be detected as German and you will not be able to see the banner in your language.

String Loading Strategy
Server-side
Good

Text prepared on the server is the most efficient way to load the text as the user does not have to download multiple languages.
