q1 ]% O1 j! j. 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） . e# w' ?8 v* ?

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.

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。$ P$ }& N( `1 g5 Z3 ~1 T' t' p8 N' O
