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）

對於 Google+1 目前是否已經對排名直接推高，Google的（發言人）Matt Cutts很快就出來跑到HackerNews上說，非也。他說

Just trying to decide the politest way to debunk the idea that more Google +1s lead to higher Google web rankings.
他繼續說這些不是谷歌信號：& K8 w" B5 x7 A, g. Q7 g

Suffice it to say that I would be very skeptical of anyone who claimed that more +1s led to a higher search ranking in Google's web results.

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。
