Quality Score is a key metric that should be used to indicate the potential for keyword, ad group, and campaign success in paid search.
On its face, Quality Score is simple: it measures the relevancy and cohesiveness of three components required for every PPC campaign:
The keywords within an ad group
The ad copy searchers see when an ad is triggered
The landing page searchers visit after clicking your ad
The more relevant and cohesive those three components, the higher your Quality Scores will be. Simple enough, but let’s dig in a little deeper.
