Patterns & takeaways

• Use split screens or side-by-side comparisons to show two sides of a story — like a before/after or a gym shot next to a recipe result.
• Add bold, contrasting text (e.g., red or yellow) to create urgency or highlight a controversial question — it draws the eye and sparks curiosity.
• Include emotional faces — shock, surprise, or intense expressions — to make viewers feel something and want to know more.
• Leverage credibility markers like "DOCTOR COACH" or professional titles to build trust, especially when discussing controversial topics like natty-or-not.
• Frame your thumbnail around a clear transformation or a powerful promise (e.g., "This changes everything") to set expectations and boost click-through.
