If you’ve spent any time at all reading up on pay-per-click (PPC) advertising through Google AdWords, you’ve probably come to realize that to conduct an effective campaign you need to pay attention to something called Quality Score. But what exactly is Quality Score—and more important—how do you ensure that you get a good one?
Although Google keeps its exact algorithm (or formula) for calculating a Quality Score under wraps, if you understand the key factors that go into a Quality Score and apply some basic best practices, you’ll reap the benefits (lower cost, better ad position) and run a more successful campaign.
What Is a Quality Score?
At the heart of an AdWords campaign are its ad groups. An ad group is made up of a set of tightly related keywords and one or more ads that will direct searchers to a particular landing page on your site whenever their search term matches a keyword in the ad group and they click your ad. The interplay of the components in a particular keyword–ad–landing page unit, its historical performance and effectiveness, and the performance of your AdWords account as a whole are at the heart of a Quality Score.
With that in mind, here’s the definition of Quality Score that you’ll find on the Google AdWords site:
“Quality Score … is a dynamic metric assigned to each of your keywords. It's calculated using a variety of factors and measures how relevant your keyword is to your ad group and to a user's search query. The higher a keyword's Quality Score, the lower its cost-per-clicks (CPCs) and the better its ad position.”
The two key take-aways in this definition are
Google’s primary goal—always—is to enhance the searcher’s experience (which ultimately puts money in Google’s pockets because satisfied searchers will continue to use the search engine over its competitors). So for AdWords, that means serving up the most relevant, enticing and fulfilling ads (and indirectly landing pages) for a particular search term. This need spawned the Quality Score ranking process that incentivizes advertisers and rewards those that provide highly relevant ads and landing pages. Before launching the Quality Score model in 2005, AdWords (and others) tried less-effective cost-per-thousand (CPM) pricing (like print advertising does) and simpler cost-per-click bidding processes.
Stay tuned until the next post, when we dig-in to some specifics....

The two key take-aways in this definition are
- AdWords calculates a Quality Score for each keyword based on two kinds of relevance.
- A Quality Score is dynamic, which means its value adjusts and updates frequently (in fact, every time your keyword matches a search query and has the potential to trigger an ad) in response to a variety of factors in your ad campaign that relate to the general concept of performance.
- Google calculates Quality Scores differently for ads that will appear on Google search, its search network and its content network. (In this post, we focus on Google search.)
- Google makes a few adjustments when it calculates the Quality Score for top-positioned ads vs. side ads. For example, ad position top #1 gets the most clicks of any ad on a search results page, but some of those clicks are strictly “impulse” clicks; Google compensates for that factor.
- Other PPC advertising programs you might be familiar with also use a Quality Score–type metric: Yahoo! Search Marketing calculates a Quality Index; Microsoft adCenter uses Quality Based Ranking.
