Clickability Index.
While the ELM Score applies a published academic model, the Clickability Index is a proprietary Thumbiq metric: six dimensions that capture why a thumbnail creates the urgency to click. It doesn't replace the ELM Score — it complements it. An asset can be technically solid and still not trigger the click, or the other way around.

The 6 dimensions.
Emotional contrast
The intensity and opposition of emotions within the frame.
Incomplete narrative
The thumbnail leaves an open question that only the video can answer.
Surprise element
Something unexpected, unusual or out of context that stops the scroll.
Text that creates intrigue
Visible copy that triggers curiosity without revealing the outcome.
Recognizable figure
A figure the target audience identifies instantly.
Thumbnail ↔ title coherence
Whether the thumbnail and the title tell the same story, reinforce each other or contradict each other.
Some dimensions are read differently depending on the asset’s format: a product thumbnail, an editorial one or a scene-based one is evaluated with the criterion that fits it.
How to read the result.
- Each dimension is scored with a written justification, so you know exactly why it got that score.
- The total is expressed from 0 to 100 and read on a scale from Low to Very High.
- The report also checks whether thumbnail, title and description are aligned with each other in keywords, tone and narrative.
Two readings of the same asset
The ELM Score measures the technical side and the Clickability Index the editorial side. They are read together, but neither changes the other.
