GroupM / Greenhouse x Bollify


GroupM faced the challenge of clearly communicating the value of Sponsored Products to new clients. Traditional metrics such as ROAS, ACOS, and Clicks were essential but did not provide a comprehensive view of overall performance, particularly concerning organic rankings and the balance between organic and paid sales.


The encounter with Bollify

The quest for a solution led GroupM to Bollify, a tool that promised to go beyond traditional metrics. The collaboration began by using Bollify as an essential benchmark before the start of new projects, enabling GroupM to measure immediate effects on organic rankings.

"It is often challenging to convey the added value of Sponsored Products to new clients using metrics such as ROAS and Clicks alone. While these metrics are important for tracking progress, they fall short in measuring overall performance. That's why we emphasize the importance of qualitative content and discuss the side effects on organic rankings and the ratio between organic and paid sales with our clients. We use Bollify as a benchmark in new projects and even with existing clients to measure changes in strategy or content. This allows us to show immediate effects and evaluate our impact over time, enabling us to continuously set new goals."

Concrete results with existing clients

A concrete case illustrates the success of this approach. After implementing best practices with an existing client, GroupM focused on improving the organic ranking of bestsellers. With daily monitoring using Bollify, campaigns were optimized and investments were strategically directed. The result? Specific bestsellers organically climbed to the top 10 of their category, leading to significant growth in organic sales. With measurable figures:

Steel Vacuum Cleaner:

  • Ranking: From 39th to 9th
  • Organic Sales: From 12 to 42


This represented a 250% increase in organic sales volumes and a 77% improvement in organic ranking.

Mini Freezer:

  • Ranking: From 17th to 5th
  • Organic Sales: From 16 to 41


This resulted in a 156% increase in organic sales volumes and a 70% improvement in organic ranking.
