Baidu has officially claimed that it does not care if a URL is a static one or a dynamic one, and that it has no strategy of discriminating dynamic URLs.
It is known that search engines cannot handle dynamic URLs properly, because such URLs contain too many parameters and would probably create “black holes”, which drag web crawlers with numerous identical content yet different URLs.
Baidu said it has “relatively perfectly” resolved this problem, but it also added that dynamic URLs shouldn’t contain too many parameters – like dozens of them, as that would scare Baiduspider.
And Baidu’s general principle for URLs is: it’s no matter whether your URLs are static or dynamic, just don’t be repetitive.
Besides, in another official document on SEO, Baidu also pointed out that URLs of a website should be descriptive, ordered and simple, in order to make it easy for visitors to remember them and prejudge content on the pages, and for search engines to crawl your sites efficiently.
