New AdWords Quality Score Info: What You Need To Know

By now, you’ve probably seen (or at least heard about) Google’s recent video and new white paper about Quality Score in AdWords. In fact, when I first heard about the updated Hal Varian video, I was a bit surprised, given that Google hasn’t bothered to update it for about five years!

Whenever Google officially communicates information about their various algorithms, for obvious reasons there’s often more going on than meets the eye. In my column today, I’ll share with you my take on what you really need to know about Google’s new Quality Score information.

What The Heck Is Going On?

At face value, the new material appeared to be an update of the older stuff, which is Google’s official position relating to how Quality Score results in happy customers, happy advertisers and a happy Google.

However, there was one rather huge change in positioning from previous materials — Google downplayed the importance of Quality Score in the white paper, stating:

Quality Score is a helpful diagnostic tool, not a key performance indicator. […] Your Quality Score is like a warning light in a car’s engine that shows how healthy your ads and keywords are. It’s not meant to be a detailed metric that should be the focus of account management.

This just doesn’t add up. We know that Quality Score impacts ad position, impression share and cost-per-click. These metrics, in turn, directly affect the quantity and cost of your conversions. This — combined with the fact that as average Quality Scores have drifted lower over the years, the CPC savings of above-average Quality Score keywords is now worth up to 200% more than it was four years ago – certainly suggests that Quality Score is a key performance indicator.

And don’t take my word for it — in Google’s own 2011 video, “What is AdWords Quality Score and Why Does It Matter?,” Quality Score seemed much more important than a blinking engine light:

Quality Score is important in order for your ads to be successful. However, Quality Score also plays a key role in determining your ad’s position and how much you’ll pay for a click. In general, the more relevant your ad, the higher your Quality Score – and the higher your Quality Score, the better your position and the less you will have to pay for a click. [...] Being successful with AdWords means getting your products or services in front of the people who are most likely to become your customers, and a high Quality Score can help make that happen.

So, the real question to me isn’t whether or not Quality Score is a KPI, but why Google is suddenly reversing course and downplaying Quality Score’s significance.

Ahead Of The Curve

We know that Quality Score (for both AdWords and Bing Ads) is mostly just a matter of beating the expected click-through rate for a given ad position. Ads that get above average CTRs get higher Quality Scores, and vice versa, as shown here:

quality-score-CTR

So, Quality Score is graded on a curve. Not everyone can achieve above average Click Through Rate — by definition, half of AdWords advertisers will be below average, and so it’s not possible for everyone to get high Quality Scores.

By my estimation, a disproportionate amount of Google’s $50 Billion in AdWords revenue comes from low Quality Score Keywords which are much more expensive due to the high CPC tax (up to 400%) that Google imposes on below-average performing keywords.

With so much at stake, it makes sense for Google to downplay the importance of Quality Score. After all, since it’s impossible for every advertiser to achieve high Quality Scores, an admission by Google that Quality Score is a crucial metric would essentially alienate roughly half their advertiser base. Regardless, you, as an individual advertiser, should know better than to treat Quality Score as just a “helpful diagnostic tool.”

How Is Quality Score Calculated?

One other big change I noticed was around the specific explanation of how Quality Score is calculated. Previously, Google used to say:

Only exact match keyword data on Google Search is used to determine a keyword’s Quality Score. This means clicks happening on phrase or broad match keywords do not factor into QS.

However, now Google has added:

Instead of measuring new keywords from scratch, we start with info about related ads and landing pages you already have. If your related keywords, ads and landing pages are in good shape, we’ll probably continue to have a high opinion of them. Always invest in growing your coverage on relevant searches, especially in areas where your ads have the potential to be high quality.

So, what does this mean? For starters, it means that they previously omitted key information. My read of this new info is that if your account has above average click-through rates, it will help out new keywords — this is consistent with what I see in the accounts I work on. This implies there are two things that advertisers should be doing:

  • Bid on Branded Keywords. One way to raise your overall account CTR is by bidding on branded keywords. We now know that having a higher overall CTR will help with new keyword Quality Score.
  • Delete Poor-Quality Keywords. Conversely, it’s worth considering deleting existing, poorly performing keywords. If you don’t, the CTR of your poorer keywords will negatively impact the Quality Scores of new keywords.

Don’t Believe Everything You Read (Except This)

The fact that Google included more information in their latest white paper suggests that they weren’t telling us the whole story with the old information. However, that doesn’t mean you have to swallow everything they’re telling you now, either.

Google omitted vital information in their old material, and with fair reason. After all, they have to protect their algorithms to prevent people from gaming the system. However, I personally doubt that they’re giving us the whole story this time, and I’d advise that you do your own research and take Google’s new information with a grain of salt.
