Is your Sustainability communication effectively helping your brand grow or rather putting it in jeopardy?
Let's test it!
In collaboration with Prof. dr. Gino Verleye (UGent & VUB) and iVox research company, Bubka developed a survey that scores your ads on the 5 features that determine your ads’ credibility. Additionally, we’ll benchmark your score against 100 Belgian ads (national and international brand ads) previously tested.
Here’s what we have learned from testing 100 Belgian commercials:
- 81% of sustainability ads lack credibility
- only 13% of sustainability ads create brand preference
- 63% of sustainability claims are not understood by consumers
- 83% of sustainability claims are considered greenwashing
Key Takeaways from the study
Whe discovered the key drivers of credible sustainability communication. And this credibility deficit learns us that the storytelling of sustainable products does not follow the same rules as storytelling of conventional products.
