Results
Vestiaire Collective has achieved a notable performance improvement with Producthero CSS for their shopping campaigns in Germany, demonstrating a 17% decrease in CPC.
Objective of the case study
We launched two campaigns in Germany with the same inventory (products), bidding strategies, budgets, and assets running on two different CSS platforms (Google vs. Producthero) and monitored the performance over a one-month period.”
“Switching from Google CSS to a third-party comparison shopping service (CSS), in our case Producthero, was a relatively easy process. Our primary objective was optimizing traffic costs by attaining lower CPC rates, achieving more volume with equivalent investment, or a strategic combination of both.
Thomas Ferreira, Senior SEM Manager, Vestiaire Collective.
Results of switching from Google CSS to Producthero
“After five weeks of running the campaigns, we noted a substantial 17% decrease in CPC for the campaign utilizing Producthero CSS compared to the Google CSS campaign.
The Producthero campaign was also able to scale more effectively due to higher purchasing power, therefore we noticed an increase in scale while using the same bidding strategy and budget.
We saw an improvement in ROAS which is a direct result of the decrease in the CPC (Cost-per-click). With Producthero, we were able to scale higher two weeks after the campaign launch. The CPC gain was evident during the test period.”

Based on these successful results, Vestiaire Collective has decided to continue with
Producthero and expand their shopping campaigns in all eligible CSS countries* in the upcoming period. This strategic move aligns with VC’s commitment to optimize campaign performance to achieve cost-efficiency across markets.
