If the second slide matters, why is it hidden behind a timer?

Motion is not prioritisation

Carousels are usually a symptom of indecision. Three messages compete for one slot, so the design rotates them and calls it engagement. Nobody reads slide two.

The hero has one job: make the next action obvious. That job benefits from stillness.

What to do instead

Pick one argument and make it well. If you genuinely have three, give each one a section with its own beginning and end. Let the page be long enough to hold the story.

Motion should then be used to explain, not to hide. A transition that reveals the structure of the page is worth more than a timer that hides it.
