It turns out that using a human voice in advertising can increase conversions by 12%.
Google has updated its creative guidelines for YouTube, highlighting just how important ad creative is to campaign performance. According to Google, creative accounts for up to 49% of campaign ROI, and improving video ads can more than double returns.
Key insights:
– Voiceovers can increase conversions by 12%, while text overlays provide an increase of only around 3%.
– Showing the brand within the first five seconds can increase conversions by 4%.
– Avoid adding buttons, arrows, or other elements that resemble the YouTube interface to your creatives. They can compete with the platform’s actual calls to action and distract viewers.
– People in the frame perform better. Showing a face or a person interacting with the product helps viewers imagine themselves using it.
The takeaway is simple: algorithms matter, but people buy from people. Improve your creatives, make your brand visible early, and don’t forget the power of voice.
