Things You Need to Know About Bing Ads Quality Score

As a Bing Ads product manager specializing in campaign optimization, I often get asked the differences between Quality Score on Bing Ads and AdWords. In order to answer that, we first have to understand why Quality Score was developed and its components. Simply, the goal of Bing Ads Quality Score is to help advertisers optimize the quality of their campaigns.

It’s designed to identify campaign optimization opportunities instead of measuring campaign optimization results. This approach enables Bing Ads to be more transparent in providing insights to advertisers through Quality Score so you can be more effective in improving your campaigns performance.

How Bing Ads calculates Quality Score

In order to provide broader and deeper insights, in addition to tracking the performance of individual keywords during the auction, Bing Ads also:

• Factors in marketplace competition while generating Quality Score by comparing potential click-through rate (aka: clickability) of your keywords to potential click-through rate of other keywords targeting the same traffic.

Example 1: Clickability Comparison

• Provides ad group and campaign level Quality Score by aggregating (impression weighted) associated keyword Quality Scores.

In addition to analyzing individual keyword’s potential CTR with competition, to help advertisers cultivate lifelong value of their customers, Bing Ads provides specific feedback on landing page relevance and landing page user experience from search users’ perspectives. In general, search users take two immediate actions after arriving in your landing pages:

  • Locate information – searchers want to consume the information right away.
  • Judge information – once located, searchers will assess whether the information addresses their intent.

For example, when people search for “Seattle golf vacation”, they want to access the information immediately and will assess whether the information enable them to proceed with their purchase journey of a golf vacation at Seattle. Over the years, I often notice some advertisers address only one of these two activities and lose out on opportunities to grow their business.

Using the same example, some landing pages ask searchers to enter a phone number or email address before showing general golf vacation information, which generates a poor user experience. Some landing pages show a long list of various vacation packages unrelated to golfing, also resulting in poor relevance.

How Bing Ads brings them together to generate the Quality Score

  • Having a “Poor” in one of the subscores makes the ad less eligible to be served and could lower its Quality Score to below a 6.
  • Not having a “Poor” in any of the subscores makes the keyword/ad fully eligible to be served and earns a Quality Score of 6 or higher.
  • Having a “Good” Keyword Relevance subscore indicates the ad has a higher CTR than most of other keywords/ads targeting the same traffic and drives its Quality Score higher than 6.
