This week, Baidu started including “Baidu Share” data in its search results.
It looks similar to Google +1, but it does not work exactly like Google +1. The data is from Baidu Share, and it only applies to websites that have Baidu share code. The functionality should be still in the testing stage, and it should not affect page rankings.
However, we are all interested to know if will affect the click through on organic search results when comparing with those results that do not have the “liked” sign.
To acquire the “Baidu Share” code, you can go to http://share.baidu.com/. The code is free, and you have quite a lot of options for the presentation of this share function on your site.
