Thumbstop Ratio
1. What is Thumbstop Ratio?
Thumbstop Ratio is a creative performance metric that measures the percentage of people who stop scrolling for at least 1 second after your ad appears in their feed.
It is essentially the platform’s measure of:
“Did your creative grab attention instantly?”
Thumbstop Ratio is one of the earliest and most powerful indicators of:
creative strength
hook quality
storytelling velocity
first-second engagement
potential conversion performance
Platforms like Meta use thumbstops as a leading predictor of Estimated Action Rate (EAR) and Engagement Rate Ranking.
2. How is it calculated?
The Thumbstop Ratio formula is:
Thumbstops ÷ Impressions × 100
More precisely:
A thumbstop is counted when a user pauses scrolling on your ad for 1 second or longer, even if they do not like, comment, click, or watch further.
Example:
If 10,000 people saw your ad (impressions)
and 1,200 stopped long enough to register a 1-second pause,
Your Thumbstop Ratio =
1,200 ÷ 10,000 × 100 = 12%
3. What does it tell advertisers?
Thumbstop Ratio reveals the attention-capturing power of your creative.
A strong thumbstop ratio signals:
your visual hook works
the creative is interrupting feed flow
users show early interest
potential for strong engagement
potential for high conversion likelihood
A weak thumbstop ratio signals:
your creative is being ignored
users scroll past too quickly
your hook is weak or irrelevant
the platform deprioritizes your ad
Thumbstop Ratio is one of the strongest predictors of whether a creative will scale or fail.
4. Why does this metric matter in campaigns?
A. Drives the Algorithm’s First Impressions
Platforms use thumbstop behavior to estimate:
relevance
user interest
likelihood of further engagement
conversion potential
A strong thumbstop signal improves EAR, which improves auction value, which lowers CPM.
B. Impacts Costs (CPM, CPC, CPA)
High thumbstop ratio → lower CPM
Low thumbstop ratio → higher CPM
Because ads that don’t capture attention make platforms hesitant to give them reach.
C. Predicts Creative Fatigue
As fatigue kicks in, thumbstops drop before costs rise.
Pro marketers watch thumbstop decline as an early warning sign.
D. Improves Creative Testing
In early testing rounds:
Thumbstop Ratio is the fastest signal of a winning creative.
It often predicts winners before CTR or CPA stabilize.
E. Influences Engagement Ranking
More thumbstops → more early interactions → higher predicted engagement.
5. How to diagnose performance using this metric
Strong Thumbstop Ratio (10–25% depending on niche)
Indicates:
strong hook
compelling opening frames
good pattern-break
native-feel creative
high potential for scaling
Recommended next steps:
A/B test variations of the hook
Expand the audience
Increase budget gradually
Test CTA variations
Average Thumbstop Ratio (6–10%)
Indicates:
acceptable but improvable creative
resonance with a subset of the audience
room for hook or visual improvement
Recommended next steps:
Adjust first 1–3 seconds
Change framing style (zoom, crop, angle)
Swap intro line or opening motion
Weak Thumbstop Ratio (<6%)
Indicates:
weak hooks
poor scroll-stopping visual
creative mismatch with audience
platform deprioritization
Recommended next steps:
Rewrite the first line of your script
Replace the opening shot
Add motion/transition
Fix creative clarity or offer mismatch
Test new concepts entirely
