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)

他繼續說這些不是谷歌信號:

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.

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。
