We tested it.
Same audience. Same budget. Same 7-day period.
Static image ad: 1.2% click-through rateVideo ad: 5.8% click-through rate
The video got 5x more clicks.
Why Video Wins (The Science)
When you scroll past a static before-and-after photo, your brain processes it as information: "Oh, that's a result someone got."
When you watch a video of someone talking about their transformation? That's different. That triggers emotion, belief, and action as well as human connection.
Video forces engagement in ways static images can't:
Autoplay with sound = Stops scrollers (images don't)
Narrative arc = Your brain follows a story
Emotional response = Seeing someone smile is more powerful than a photo of teeth
Proof through movement = You see them move, speak, transform—not just a frozen moment
Where Video Outperforms Most
Cosmetic dentistry: Before/after photos work. Before/after videos convert 3x better because you see their confidence shift
Gym transformations: Photos show end result. Videos show the energy, the process, the lifestyle
Physiotherapy: Photo shows "person without pain." Video shows "person DOING activities pain-free"
Aesthetic treatments: Photo shows result. Video shows someone's actual words about how it changed their life
The Numbers Across Platforms
Facebook: Video gets 10x more organic reach than image posts
Instagram: Reels (video) get 30% more engagement than carousel (images)
LinkedIn: Video gets 5x more engagement than images
TikTok: Video-only platform (obviously crushes)
Still Images Have Their Role
This doesn't mean delete all image ads. Static images still work for:
Retargeting (reinforcement)
Carousel ads (showing product variety)
Testimonial quotes (text + image)
But if you're allocating serious budget, video should be 70%+ of spend.
What to Do This Week
If you're running image ads, test one video ad against your best image. Run for 3–5 days. Compare click-through rate, cost per click, and conversion rate.
Chances? Video wins. Then reallocate budget. This is the same formula we set up when performing ads for our clients. Test and retest.
