在英文论坛上看到一段有趣的评论，里面涉及到中文SEO和英文SEO的差异：

The most popular Chinese search engines are Baidu and Google (Chinese). There's nearly few difference in doing Chinese and English SEO. The most import thing is to choose the right keywords which is very difficult for non-Chinese to do so. If you have difficulty to find your ideal search term, please let me know. Actually, SEOing for Chinese terms is very easy because it is far less competitive than optimizing for English terms. Below are a few basics.

>>keywords in title
>>keep the keywords at the beginning and end of the page
>>3~10% keyword density
>>h1, h2, h3
>>bold, strong tags
>>anchor text links in internal pages, it is still very powerful for Chinese search engines.
>>external anchor text links, nearly all external links count, Google Chinese is not good at finding which link is an authority or expert or spam, if you don't have link resources from Chinese sites, your can have anchor text links from your English or other language pages. Many Chinese SEO sites get links by spamming the English blogs, wikis, free-for-all link page....and there are jus doing well.
