Certificates cost real money and months of study, so picking a bad one hurts. Worst is the word doing the pulling, because you might already own one. The tier board shows the famous logos floating unplaced, so the verdicts stay hidden until you click.
How the packaging works
Title
The title pairs best with worst so both owners and shoppers feel stakes.
Thumbnail
The thumbnail shows the tier board and the logos, with every ranking withheld.
Remix this
If your viewers spend money on options you can judge, rank them on a tier board and keep every placement off the thumbnail. Owners click to defend their choice and shoppers click to avoid a mistake.
The transferable lesson
Rank what they already bought and hide the verdicts
