In this post I continue to look into SEO for Baidu and how it differs from more familiar Google-based optimization.

SEO for Baidu is not just a one time job but, just as in the case of Google, is a continuous effort. Algorithms and weights of various factors change all the time and, in a way, Baidu seems to be following Google’s logic, although with a considerable delay.

Of course, since Baidu targets Chinese audience, it has its own way of doing things in order to stay more relevant both geographically and linguistically.
