When people are talking about Google Penguin, Baidu has come to change its algorithm of organic listing recently as well.

If you query for “site:www.yourdomain.com” on Baidu, you will find most of page description tags don’t work anymore, but are replaced by others which come from its body section of page content. Baidu prefers to display what it scratched from body content, instead of what you declare in description tag.

Therefore, those keywords rankings with keywords rich in description but less on body part, would be strongly impacted rapidly. If you are in the category, you have to re-construct your CMS (content management system) with keywords being deployed on body parts.
