This infographic was designed to give an easy, but powerful, methodology to measure the optimization level of an AdWords account by looking at 3 Key Performance Indicators (KPIs). It analyzes the level of efficiency, looking at the quality score of the most expensive keywords and thus giving a precise answer to the question: Am I getting the lowest PPCs I can?
Afterwards it looks at effectiveness, analyzing conversion rates of top items (keywords, placement, and shopping products) and answers the question: Am I buying the right clicks?
And finally it considers the coverage, that is impressions and shares of top items, answering the question: Am I getting the best clicks?
