I recently read a book about Quality Score entitled Quality Score in High Resolution by Craig Danuloff. The book really shed light upon the different factors that influence Quality Score calculations. This made me realize that there are currently an endless number of amature and professional blog posts that have created a lot of confusion in this area. This confusion appears to have led account managers, amatures and experts, to the conclusion that Quality Score is the enemy; however, this is not the case.
Quality Score is Google‘s way of helping the good and punishing the bad. It serves as a motivation for advertisers to create well organized and honest PPC campaigns, ensuring that there is more to online auctions than just over bidding.
