Creative Distance Index (CDI).
The CDI evaluates the creative device behind a thumbnail — the metaphor, the wink, the conceptual connection chosen — not its technical attributes. It is an editorial metric: it doesn't come from the Koh & Cui model and it changes neither the ELM Score nor the Clickability Index. It builds on the idea of associative distance from the vRAT framework (Olteţeanu & Zunjani, 2020).
← Back to What the system measuresIt doesn't appear in every report
It is reported only when the asset uses an identifiable creative device — a visual joke, a reference, a twist. A generic thumbnail without that device omits the section.
Two questions.
Conceptual distance
How far is the idea from obvious or expected territory? It is expressed as a rating of Originality.
Clarity of the connection
How quickly is it understood, without further explanation? It is expressed as a rating of Simplicity.
Four possible readings.
Optimal Zone
It goes far from the obvious and is understood at first glance. The ideal.
Predictable
It's understood, but stays close to the expected: safe, not very memorable.
Confusing but ambitious
It takes a risk and goes far, but it's hard to understand. The clarity needs reinforcing.
Irrelevant
It neither surprises nor connects. The worst case.
