What the data shows
Slide 1 gets 80% of clicks. Slides 2+ get 1-2% each. You're essentially making 4 of every 5 visitors see your worst content.
What to use instead
A well-designed grid, a tab component, or a vertical list. All outperform carousels on click-through and time-on-page.
When carousels are OK
Image galleries where the goal is visual browsing, not clicks. Otherwise — don't.
