Client Questions

  • How many customers visited thanks to media?
  • What else did they purchase, other than the promoted products?
  • Which are the best-performing star promotions?
  • What is the optimal marketing mix and investment level by media type?
  • Which are the best-performing seasons and weekdays?


The Finnish retail landscape had been extremely price-driven for many years, due to static consumer purchasing power and a tight competitive situation.

  • As a result, marketing messages focusing on price and promotion had become the market standard.
  • Delicatessen's media spend was focused on traffic-driving weekend price campaigns.
  • However, there was a lack of proof regarding which categories were bringing in traffic and which were not.
  • Consequently, all categories were promoted in the media, even though only a few performed well.

Delicatessen had a strong media performance as the starting point.

  • There was a clearly positive margin ROI for media investments overall.
  • They had a differentiated theme, featuring high quality and delicious pictures. However, they lacked analytical tools to provide actionable insights for continuously improving marketing performance.
  • Marketing performance was analyzed too infrequently, with results only at the media type level.
  • There was a lack of understanding regarding which messages, themes, media, seasons, and star products performed the best.

Client Testimonials

We have previously done marketing activities and campaigns in a vacuum, lacking deep enough analytics to give feedback on our performance. Sellforte has provided insights on what in our marketing works and what doesn’t. Now for the first time, marketing and merchandizing get easy and understandable feedback from their own work to make better decisions in the future.
