We Tested Tu Creatives With and Without Dynamic Video Captions

Dynamic Video Captions were applied on Tu's video ad tags. In order to test the effectiveness the delivery of video ads had on comprehension, Sharethrough showed participants several videos with and without Dynamic Captions. The videos were followed by a list of questions to assess the impact they had on consumers’ message comprehension, awareness, favorability and purchase intent.

Results of Tu's Video Advertising Campaign

By adding Sharethrough’s Dynamic Video Captions to their campaign, Tu increased all brand metrics while improving efficiency.

The results revealed Dynamic Captions delivered an increase in every major brand metric including a 19% increase in message comprehension, 4% increase in awareness, and 5% lift in favorability

Additionally, Dynamic Captions and programmatic campaign optimizations by Essence Digital UK, resulted in a 19% higher comprehension than industry benchmarks for similar video ads. On top of that, with Dynamic Captions, Tu's video had had better attention and comprehension than editorial content on the same page with 93% overall campaign viewability and a 71% video completion rate.
