Bounce Rate is NOT a Factor in Quality Score

I get asked all the time about quality score.  So instead of responding to all those questions with something that I knew to be true, I went to the source:  Google.  They confirmed today that Bounce Rate is NOT a Factor in Quality Score.

This email is here to confirm your suspicions about bounce rate on your website.  I however am still very skeptical about this because of the nature of the bounce.  When a person bounces it shows that they are not interested in what your site has to offer.  Typically this would show Google or any other site that the site they just visited wasn’t relevant to the search or the click they just paid for.  Does this comply with Google always trying to give the best experience possible?  NO in my opinion.

Bottom line: Bounce Rate is NOT a Factor in Quality Score
