Search term report opacity
In September 2020, using its concern over privacy as a justification, Google Ads considerably reduced transparency on its purchase platform with a major reduction in access to campaign source data from its search network: the search terms.
“In order to maintain our standards of privacy and strengthen our protections around user data, we have made changes to our Search Terms Report to only include terms that a significant number of users searched for. We’re continuing to invest in new and efficient ways to share insights that enable advertisers to make critical business decisions.” – Source
Search terms are the most important data for any campaign managed on the search network. This report shows users’ searches for which we’ve received impressions and clicks and made investments in our budget.
This reduction in transparency has caused so much turmoil that a petition was launched to demand the update be abolished, but it’s impossible to fight against a giant like Google. It was a lost cause from the very start.
Since the September 2020 update, around 50% of search term data has been affected, which has caused huge opacity with regard to delivery of results and investments. Possibilities for optimization and control of delivery have been greatly reduced, which has had a direct impact on the effectiveness of advertising campaigns, particularly with regard to the Quality Score. The Quality Score is composed of three elements: the engagement rate (CTR), which composes 75% of the Score; the correlation of the ad with the query, which constitutes 25% of the Score; and the quality of the landing page. Considering that, on average, 30% of search terms are available, users of the platform have lost 50% of their optimization capacity and must now put their trust in the “system,” which, evidently, serves the interests of Google.

Here is a recent example of available and unavailable data (“Other” queries) in the search term report. The “other” queries are also known as the “blindfold,” a subject we already covered in another article.
We tried to see if the queries that were unavailable in the user interface (the front end) were in the database (the back end) by using tools that connect directly to Google data through the API, such as SuperMetric and BigQuery. Unsurprisingly, the query was completely hidden, even for advanced users connecting directly to source data through API connections.
Reduction of control in keyword matching, transition of BMM to enlarged Phrase matching
As you can see, while we can narrow our targeting to Phrase, we can still display on undesirable queries, such as, for example, queries linked to fraud. So it’s essential to properly manage your library of negative keywords in order to control display. And yet since September of 2020, this has become a much more complicated task!
Each type of match receives a different efficiency rate due to its basic functioning. Here, for example, is a distribution of investments by cost per acquisition (CPA) and by type of match. This is a typical situation (a badly optimized account) where the larger the targeting, the higher the CPA. The goal therefore is to target as narrowly as possible in order to reduce the CPA.
As you can see, Broad (including BMM) has a CPA 1,877% higher than Exact, with 509% more investment. That’s why we always recommend saturating Exact and Phrase before even thinking about Broad or BMM (Broad Match Modifier).
Here is the same account after the marketing activities have been taken over by Adviso. We can see here a well-structured, optimized account. Exact is saturated, thereby maximizing performance, and has a CPA that is 80% lower than Phrase.
That being said, Google has taken another step towards data opacity by fundamentally changing the way Match Type BMM and Phrase work.
February 18 will mark the start of a transition for BMM towards an enlarged Phrase, leaving more room for Phrase to be admissible to user queries.
As Google’s press release on the subject emphasized, Phrase will gradually take more and more impressions by positioning itself on queries that we can’t necessarily verify in the search term report . Meanwhile, BMM will get fewer and fewer impressions until it is retired in July of 2021.
This change will definitely have an impact on account performance. For accounts relying a lot on Broad (which we don’t recommend, though not for the reasons outlined above), performance should gradually increase. However, for already optimized accounts that rely on Exact and Phrase, we should see for Phrase:
- an increase in impressions;
- a reduction in the quality score;
- a reduction in CTR;
- an increase in CPC;
- a reduction in the conversion rate;
- an increase in CPA;
- a reduction in ROAS (for e-commerce accounts).
