NBCF was offering free healthy living tips as an acquisition offer, and wanted to test whether adding a question in the headline would increase people’s motivation to download the offer.
Does asking a question in a headline convert more people than an actionable value prop?
|Treatment Name||Conv. Rate||Relative Difference||Confidence|
This experiment has a required sample size of 212 in order to be valid. Since the experiment had a total sample size of 2,049, and the level of confidence is above 95% the experiment results are valid.
Flux Metrics Affected
The Flux Metrics analyze the three primary metrics that affect revenue (traffic, conversion rate, and average gift). This experiment produced the following results:
0% increase in traffic
× 19.1% decrease in conversion rate
× 0% increase in average gift
The question headline decreased conversion by 19%. It’s possible that because we were asking a question rather than giving them an actionable charge, “Start living healthier this week,” that people were less motivated by the headline to convert.
