Facebook pages are global by nature. Brand pages most likely have fans that come from different parts of the world, and this is especially true for international brands. Make sure you communicate your message to all your fans, regardless of what language they speak.
It's not uncommon for companies to have employees from different nationalities, but it may be uncommon for companies to have employees who can communicate with all fans in their own tongue.
As part of our community support, we have multilingual team members who can translate contents, respond to comments, and engage with fans in their own language.
