A Different Way to Think About Ad Relevance in Quality Scores

Ads, Quality Score

Ad Relevance makes up 22% of your visible quality score and it can be a difficult item to work with since it doesn’t always make logical or semantic sense.

For instance, an easy way of thinking about relevance is semantically. If the keywords and overall idea is in the ad, then the ad should be relevant. If the keywords and ideas aren’t in the ad, then its not relevant.

If you’ve been advertising for a while, you’ve come across many examples where that just doesn’t seem to be true. Now, the most common of these are for ‘related’ or ‘complimentary’ products. For instance, many mortgage companies will advertise on real estate terms. The idea is that if a user is looking to buy a house that they will need a mortgage; and thus a new keyword with poor relevance is born.

Why?

Mortgage is a financial intent search.
Real estate is a location intent search.

An easy way to think about relevance is via the game ‘taboo’. In that game a player is given a card, and their goal is to have other users guess what’s on that card without saying a few choice words. For instance, if someone says:

  • Rate
  • Calculator
  • 30 year fixed
  • 5 year arm
  • PMI
  • Buying a house

The word being talked about must be mortgages. Those words are semantically related terms.

However, relevance within quality score can be thought about within the game taboo from a mental exercise, and it often works well. Algorithms don’t think – they just examine numbers.

For instance, if a user is looking to book a cruise; these two ads seem to be relevant (look at the ideas; not the lines and character limits):

Ad 1:

Book Your Dream Cruise Today

Save 10% by booking online!

Ad 2:

Book Your Dream Cruise Today

Travel to Alaska in Style!

From a algorithm standpoint, what we really have is someone looking for a cruise and two ads that use these components:

Ad 1:

Headline: Call to action

Description: % discount

Ad 2:

Headline: Call to action

Description: Destination

Bing produces and shares many heatmaps. These heatmaps show us the intersection of ideas for headlines and description lines and what that intersection produces from a CTR standpoint. These idea intersections can be thought of as ad relevance.

For instance, when we look at this heatmap and find intersections of these ad ideas, what we see is:

  • Ad 1: headline – call to action. Description – % off. Green result – high CTR.
  • Ad 2: headline – call to action. Description – destination. Red result – Low CTR.

This type of data is aggregated at the industry level; so there are many exceptions as averages blend everything together and hence why you should test ads and ideas for yourself.

If you are using Multi-Ad group testing to receive customer insights, you can easily test your own hypothesis. If you’re looking for an easy way to test these hypothesis, take a look at Adalysis.

However, these heatmaps are great places to get some ad ideas and avoid some major mistakes before you start testing.
