- f4 ?; F8 j! g/ N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） % B" C& a! q! h% H$ g

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

他繼續說這些不是谷歌信號：% @2 R- A$ R% V" g1 E( M% ?

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.% A; X/ u- X3 v

Rather than chasing +1s of content, your time is much better spent making great content.4 l9 d: h7 f$ N1 B/ a! a9 e

因此看來，對於+1 ，圖表所表示的僅僅是correlation，而非causation。
