Baidu is the most used search engine in China and serps are very, very different than Google.cn I submitted a site 2 months ago but I got no results at all. I have a special section in my website written in Chinese and I have done all the SEO work with no luck. Any tips will be appreciated.
You sure that you actually got indexed by them? When you type you're url into the search engine does it show up? If not, maybe you're still stuck in a que somewhere waiting to be indexed.
If your keywords are competitive then you will never get to the first page on Baidu. Baidu mixes paid and organic searches and for competitive keywords where there are advertisers their sites will always come on top even at the left results. Even for Google.cn ranking high is not as easy for simply submitting.
