Result

Click-through on this video over its first 14 days, old thumbnail against new.

The brief

Rune & Run had a 40-episode survival series and every thumbnail was a webcam frame with the full video title written underneath. Viewers couldn't tell episode 12 from episode 37.

The goal for the Night 100 finale: make the number the hook and make the danger readable at phone size.

What changed

  • Dropped the title text. Two words and a number now carry it: Night 100.

  • Put the creator's reaction against the one thing he's reacting to, the eye in the cave.

  • Pushed the teal and amber apart so the eye still reads at 120 pixels wide.

Title options sent with it

  • Night 100 in the crystal caves

  • I survived 100 nights and found THIS

  • The 100th night was the worst one

“

Our finale did more views in two days than the previous five episodes together. The number on its own did the work.
