Baidu does not seem to index non-chinese content unless
there is at least a few characters of chinese on the page.
So if you want a page to get indexed by Baidu, then add a few chinese characters to that page
I'm going to experiment around with including chinese characters either into comments in HTML or the meta keywords to see if Baidu indexes my page. I know some english pages which only have a few chinese characters and the english keywords got indexed!
