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：

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.

Rather than chasing +1s of content, your time is much better spent making great content.

F: [$ O, h6 O# bMost 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。8 [5 E! \- x8 P3 y4 z% n0 O# ^
