The biggest hurdle they will have to overcome is developing the search algos for the English Search in what, to the Chinese, would be a second language. For a pure keyword search the process would not be as difficult, although daunting. But to develope AI Searches in second languages ... phew, big job.
Judging by some of their spelling suggestions, they've got a lo-o-ong road to go.
The algo is really strange. Very kind to internal pages, and some home pages seem to be filtered for their main target phrases.
And in some market areas, I'm seeing pages from Russia and the Middle East that I've never seen before.
