Other findings included:
Day parting drove a 20% higher engagement – this can be key for all brands. In CPG we normally consider either the receptivity moments throughout the day (for consumption or consideration), or the time when the customer’s journey can be prompted to start – dayparting is one of the earliest forms of online advertising targeting yet is often overlooked.
A single call to action performed 30% better than 2 messages appearing together – simplicity is key to creative cut-through and in getting a call to action to deliver, so this type of insight confirms one of the golden rules of advertising design.
Seasonally adjusted creative (e.g. holiday time) increased performance by 17% – this works because the relevancy of the creative to the audience’s mindset is higher. Small changes in the advertising creative can have a big impact.
Why it matters
By carefully testing creative, San Pellegrino built up a war chest of data it could use to identify which messaging and content resonated best with their consumers. By understanding which calls to action work best in which context, all future campaigns can become stronger. This type of test you only need to run occasionally and can then apply the learnings widely.
By testing, they reconfirmed some of the existing rules of digital ad design, as well as identifying new rules – and those guiding principles could then inform all campaigns
