Jansen Display online store

A strong product, with little visibility

When I started working with Jansen Display in 2015, I found good products and a broad catalogue, but the digital presence was barely producing results with total sales below €30,000 per year.

The challenge wasn't the product — it was visibility and profitability. They needed to appear on Google at the right moment with the right messages to reach potential customers. And to do it so that every euro of ad spend produced a measurable return.

Starting from scratch: with barely any usable campaign history, no reliable conversion tracking, and a catalogue of hundreds of references that needed prioritising. In under two years, Jansen Display was the sector leader in paid search.

Ten years, market by market

2015

Project launch in Spain. Annual online revenue: < €30,000. Built from scratch: accounts, conversion tracking, product feeds, and campaign structure.

2016–2017

Takeoff. Spend scales profitably and Jansen Display establishes itself as the leading company in the sector in under two years.

2018

German market opened. Simultaneous management of Spain and Germany with independent feed structures and campaigns tailored to each market.

2019

Germany increases revenue by 40% in barely a year with 7.4× ROAS. The German operation is sold as a going concern.

2020

All-time revenue high with 7.2× ROAS.

2022

Business restructuring: B2B-to-B2C model change and change of ownership. Revenue drops, but ROAS holds steady at 4.4×.

2024

Recovery to pre-restructuring revenue levels with a purely B2C model. 5.0× ROAS. The account remains profitable ten years after the first ad.
