Today we have a guest post from one of our PPC Hero allies! Craig Danuloff is doing a ‘Blog Tour’ to promote his upcoming book ‘Quality Score in High Resolution‘ which will be released in May and is now available for discounted pre-order. In this post he explains some of the lesser-known facts of the quality score metric reported by AdWords
Ready for a simple PPC question?
True or False: Quality Score is a number between one and ten that is assigned to every keyword in your AdWords account.
<Play that Jeopardy music in your head and decide.>
Got your answer?
Sorry, trick question. The answer depends on which quality score you mean.
There is a metric named ‘quality score’ that appears for every keyword in your account. In terms of that quality score, the statement above is true.
But there are other ‘quality scores’ that are used inside the AdWords system to determine whether or not your ads are eligible for auctions, which position they appear in, and even how much you pay per click. The above statements are not true for those versions of quality score.
I’ve taken to calling the first quality score, the one that is a number between one and ten and is assigned at the keyword level, visible quality score. Because you can see it.
Visible quality score is a simplified proxy for the average ‘real’ quality scores for a keyword. It is based on a simpler formula than the one used by the real quality scores. It’s also expressed in a different numerical range and distribution.
Visible quality score gives you an idea of how the keyword is performing in terms of quality score. But it doesn’t consider all of the factors that go into the more critical quality score values, so there are things it can’t tell you.
One of the reasons why quality score is so confusing is that people try to answer a lot of the questions they have about quality score, or understand the quality score issues in their account, based on what they see in the visible quality scores. But in many cases visible quality scores lack the level of detail necessary to answer or explain those issues.
Google exacerbates the issue by calling two different things by the same name. Suppose you read a help file that says ‘quality score considers the relevance of your search queries to your keywords’ and so you decide to review query performance in your account. But when you look at your search query reports, and then look at the column in your reports that is named ‘quality score’ it isn’t clear that the quality score you can see isn’t the one that is effected by search queries. It’s easy to get frustrated or confused.
Here’s a few facts that will help you to understand the limits of visible quality score:
Visible quality score has limitations, but it is useful for understanding how your keywords are performing and for managing and improving quality score. It is highly correlated with CTR (another metric where what is reported is an average giving less detail than we might want) which isn’t surprising given that’s effectively what it is tracking.
Visible quality score provides a great warning system. Since visible quality score only reflects queries that are identical to the search query, it probably reflects a relatively positive view of actual quality scores. So if it’s a low number – anything below 6 – you should worry and take corrective action.
There are at least three main issues that visible quality score doesn’t reflect that you should monitor yourself:
The quality score calculations Google performs to determine eligibility, ad rank, and CPC are complex and done in real time. It would be very difficult for Google to share this data with advertisers.
Visible quality score is not a bad compromise, but like any summary it lacks some of the important details contained in the raw data. By understanding the limitations you can get the most out of visible quality score but also know when it’s time to look past this metric to other clues to tune and improve the performance of your account.
