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, x6 G/ ? ~3 k9 _ R% Z" w

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.1 Z( I) R$ r G- [- _# G

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。6 ^6 I/ @& [0 ~! ]. m
