The Chinese market is huge, but what others here have said about it being difficult to penetrate is correct. You really need some Chinese partners on a project, or significant “local knowledge” to succeed in the mainland Chinese market.
There are a LOT of Chinese speakers who don’t live in China though, so there is definitely some traffic there worth targeting.
QUOTE=Vrindavan;179555]A tip
don’t force a site language to a surfer by geo-ip,
let them choose/switch by themselves,
default English is always safe.
I agree that detection via geo-IP is a bad thing.
You’re best off detecting language via browser settings though rather than defaulting to English.
Browsers will have a language setting, and there’s also the ‘HTTP Accept Language’ variable you can sniff.
