) i3 D/ c6 X0 P K不知道這個話題有沒有已經討論過， Google+1 是否真的目前已經對排名有直接推高的影響，是值得研究一下。這個在樓主此帖 和 TGL 8月的另一貼都出現過了。（當然是國外翻譯來） " z Y1 ?8 i: o0 T+ v) `4 G

If you make compelling content, people will link to it, like it, share it on Facebook, +1 it, etc. But that doesn't mean that Google is using those signals in our ranking.

Most of the initial discussion on this thread seemed to take from the blog post the idea that more Google +1s led to higher web ranking. I wanted to preemptively tackle that perception.
順便說一下，以前Facebook Shares也被認為有類似的效果，同樣被Cutts否定。但是後來有人提出，有+1 並非是壞事，因為，既然你的東西受歡迎，鏈多鏈高質鏈自然，排名靠前，讀者多，自然也會有更多 +1，facebook shares 等 （correlation），谷歌的算法看上去更自然。但目前，其+1數量多少並非「直接」推高排名（causation)。關鍵是」直接「二字, 間接的效果很可能有(indirectly promote links, tweets and other signals)，這裡就不詳述了。

因此看來，對於+1 ，圖表所表示的僅僅是correlation，而非causation。+ i9 F/ N4 L+ {* S0 \
