The goal of the study

The goal was the comparison of the results with and without the use of a CSS partner with our client

Testing the benefits of the CSS program Shopping in EU

Our client decided to try the shopping campaign through the Google Ads service without a CSS partner. We agreed with the client in advance that we will monitor the results for two weeks.

We finished the switchback on March 15, 2021. We then tracked how would CPC, CTR, clicks, and impressions develop in the Google Ads.

For the purpose of comparison, we chose a period of 10 days, when the client used our CSS partner Shopping in EU. We monitored the same period (10 days) after the switchback.


The CSS program affected not only CPC, which softly decreased by 5%, but also CTR, number of clicks, and impressions. The graphs show how the individual metrics changed during the period under review.
