s360 & Stockmann: Stockmann double their revenue and ROAS from Google Ads and Shopping

In addition to doubling ROAS and creating a five-digit (EUR) yearly savings, s360 also helped Stockmann become the first Finnish advertiser using Google Shopping.

The Challenge

Maximizing new ad opportunities in Google Shopping

Stockmann reached out to s360 as they wished to increase effectiveness and automate and create transparency in their former “Digital Marketing Operation Model”.

Simultaneously, they wanted help in using the new ad opportunities in Google Shopping.





Increase in ROAS
Increase in total e-commerce transactions

The Solution

A detailed migration and testing plan with automated setup

s360 performed a full audit of all Stockmann’s Google accounts and revised all the tools and technologies that were used for feed management and bidding. A five-week migration and testing plan replaced the feed management technology with a similar but cheaper system. The bid strategy was also changed from CPA-based to ROAS-based. Finally, the keyword coverage was expanded with over 500 brands, and the setup of all e-commerce products was automated.

“We have been very satisfied with our partnership with s360. The results speak for themselves: ROAS has significantly improved, and we are among some of the first in Finland to advertise our big selection of products through Google Shopping ads. With the help of s360’s proactive expertise, we have made great progress.”

- Sanna Kauhanen, Digital Marketing Specialist, Stockmann

The Results

An incremental increase in ROAS and transactions

Through Google Shopping, Stockmann saw a 250% increase in ROAS and a 400% increase in total e-commerce transactions from generic searches. In addition, Stockmann achieved a five-figure (EUR) annual saving by replacing third-party technology with new solutions.
