AdWords - Account Level Quality Score
I recently added a new campaign with new keywords and new text ads, to my account. I had these questions; How does Google attribute QS to new keywords in new campaigns with new ads? Does the QS of my older keywords affect the QS of the new ones?
I know that expected CTR, ad relevance and landing landing page experience are part of the algorythm for keywords QS. So, I decided to search for Account Level Quality Score. That's what I found. The account level quality score was supposed to be an average of your overall keywords quality score (Google denied the existance of such metric). Google reported in their whitepaper on quality score that "There is no such thing as ad group-level, campaign-level or account-level Quality Score."
I didn't find the right solution from the Internet.
