I found a very useful postin that should help you submit your website in baidu. webnots.com/submit-site-to-baidu/
I read about a year ago that Baidu doesn't accepts English language sites. I don't know where you are located, but if your site isn't in Chinese there's no way you can get listed in their search engine. At least that's what their terms of use said a year ago. It was something funky if I remember. Even the sites hosted in Hong Kong / Hong Kong based were rejected.
There is no need for me to send my website in Baidu just to index but I only submit my site in different platforms and this is to notice the major search engines to index my site, its more effective rather than focusing in just search engine submission.
