The “seen-read” ratio is an advertising impact indicator primarily used in print media to measure the visibility and readership of an advertisement. It is obtained by exposing an advertising message to individuals and then asking them whether they saw or read it, thus allowing for the evaluation of campaign effectiveness. Some studies explicitly distinguish between “seen” and “read” to refine the analysis of advertising impact. This indicator is also used in the development of personalized marketing strategies aimed at strengthening the relationship between companies and their customers.
