Hi — the lay of the land (as you put it) in China is very different to the rest of the world. For example, many services we are used to (e.g. Google Analytics) don't work (or doesn't work reliably) within China. This is due to the great firewall the government operates to censor internet content. This also means that things like Alexa, SEO, etc. takes a different form.

The best way is to partner with a local Chinese digital agency. There are several boutique agencies who have existing branches in Europe/US for this reason.

Let me know if you want some intros.
