1 Challenge

Frequently Changing Ads

In sports betting, the odds are always changing. The star football player sprains his ankle, or the basketball coach announces on Twitter that he'll experiment with a new team formation. With over 50,000 sports events a year, and an average of 250 odds changes a day, Toto faces quite the challenge when it comes to advertising. As Google’s gambling policy doesn't allow retargeting on search, Toto wanted to explore other options to follow up on people who expressed interest in a certain match or competition.

The challenge for Toto’s agency, Greenhouse Group, was simple, yet difficult: advertise Toto’s extensive and volatile range of betting options, attracting both new and recurring players. The budget was practically unlimited – as long as everything stayed within Toto’s return on ad spend (ROAS) target, so efficiency was key.
