How it is calculated
Exposure detection is largely a technical problem that broadcast monitoring solves well. Turning a logo’s seconds on screen into a currency figure is the contested part: it assumes that passive, partial exposure is worth some fraction of a bought, full-frame advertisement, and the fraction chosen drives the result.
The formula
Why measurement standards reject it as value
The Barcelona Principles, the evaluation framework maintained by AMEC (the International Association for the Measurement and Evaluation of Communication), state that advertising value equivalency is not the value of communication. The objections are consistent:
- Exposure is not attention. A logo in frame has not necessarily been seen.
- It has no direction. Coverage of a crisis generates media value like coverage of a win.
- It is not a return. It describes a hypothetical cost avoided, not revenue earned or behaviour changed.
- It is not comparable across providers. Different rate cards and adjustments give different figures for the same exposure.
Where it is still useful
Read as a normalised measure of exposure, media value does real work: it compares how much visibility two properties deliver, tracks exposure year on year, and gives rights holders a basis for relative pricing between packages. The problems start when it is placed next to the word return.
Acceptable: “This package delivered 2.4x the broadcast exposure of the previous one.” Not acceptable: “This package returned €4.2m on a €1.5m fee.” (Illustrative figures.)
What to report alongside it
Exposure becomes defensible when paired with a measure of response: change in branded search demand in exposed regions against control regions, change in share of search within the category, or a shift in audience composition. Those measure what the exposure produced. Exposure measurement specialists and response measurement are complements: one says how much was seen, the other what changed.
Common mistakes
- Media value as ROI. Cost avoided is not revenue earned.
- Comparing figures from different providers. Rate cards and adjustments differ.
- Reporting exposure without response. Pair it with a measure of what changed.
How Rascasse uses it
Rascasse does not measure exposure. It measures response: whether interest in the sponsor rose among the property’s audience and in exposed regions, against competitors and control regions. Teams that already buy exposure measurement use the two together.
