When an activity claims to satisfy multiple goals it is perceived as less effective than an activity with a single dedicated goal.
Students rated aerobic exercise as a more effective means of achieving a goal when it was described with one health goal (protecting from heart disease) than two goals (protecting from heart disease and maintaining healthy bones).
UNSEEN OPPORTUNITY
To maximise perceived effectiveness, you may need to claim to do just one thing well rather than present a longer list of I multiple benefits.
