Raffle Ticket Seller Proves GWP Is Not a Gamble

Tyviso have partnered with a UK company that offers property prize competitions, giving people the opportunity to win homes and other high-value prizes through organised draws. As a digital-first business, they’re constantly looking for ways to optimise performance and increase customer conversions. To support this, Tyviso scientifically tested whether adding a Gift With Purchase (GWP) widget could drive more completed checkouts and ultimately increase revenue.

Objectives
The campaign focused on two clear objectives:
- Validate the effectiveness of Tyviso’s Gift With Purchase (GWP) widget through controlled A/B testing.
- Increase basket completion rates and overall revenue by enhancing the checkout experience.
Approach
Tyviso worked with this company to perform an A/B test across their website, splitting traffic evenly between users who saw the GWP widget and those who did not.
To ensure the results were statistically robust and reflective of real customer behaviour, we ran the A/B test over a three-week period. This included their busiest time of the month, just before a prize draw, when traffic spikes significantly. Capturing this peak ensured the data was both rigorous and representative.
Results
The extended A/B test delivered 100% statistical significance and confirmed that the GWP widget positively impacted performance, including:
- 3.74% increase in basket completion rate
- 3.82% increase in revenue per view
By extending the A/B test and capturing performance across both peak and off-peak traffic periods, we ensured the results were reliable and statistically robust. The data not only offered scientific proof of the value brand partnerships can deliver, but also gave the company the confidence to roll out the now-proven GWP widget to 100% of their site visitors.
