 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. ' q3 O: k% p" |5 }/ Q他繼續說這些不是谷歌信號:

 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.6 l9 C2 `' }8 b  r3 ^* _# D& P9 W- u& k+ m! C5 e3 P. {# Y) w6 h; n4 e- b
 Rather than chasing +1s of content, your time is much better spent making great content.

 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.

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