Tomatoes took control of Slido’s performance marketing in July 2019. In our case study, we compare two date ranges 3/1/2019 – 6/30/2019 (4 months before we started) and 3/1/2020 – 6/30/2020 (YoY comparison with our marketing delivery.

As Tomas Tencer, Slido’s VP of marketing said: “Some time ago we realized that we needed to invest in advertising. As a startup company, we have to be very resourceful. We wanted to have one centralized digital media agency with proven experience in the B2B segment in various markets such as Australia, Singapore, UAE, Europe and the USA.”

How did we achieve the results?

When we started, only two countries were advertised – the UK and the USA. We utilized new marketing strategies to get more traffic on Slido’s website. We successfully managed to increase the number of conversions by 411%. An increase of this magnitude usually increases cost-per-acquisition, which did not happen in this case. CPA was optimized and reduced by 30%. Since our primary goal was performance, we had to drive not just more traffic to the website, but retain or increase the quality of that traffic as well. A 234% increase in conversion rate is evidence that we achieved exactly that.

These results are the foundation for further expansion to new markets where we advertise:


„Tomatoes helped us grow in sign-ups, leads and sales. They optimized the return on ad spend by continuous optimization of our ads, targeting and budgets in various networks. They became our trusted partner.“
