Ilmoitusmittarin

Ilmoitusmittarin is a Finnish term referring to a metric or instrument used to quantify the amount of paid advertising or notices in a media product or platform. It describes how much of a publication, broadcast, or digital space is taken up by advertising content, and is used in both industry practice and media studies.

In practice, ilmoitusmittarin can be applied in different media contexts. In print, it may be expressed as the share of page area occupied by ads, the number of advertisement units per issue, or the proportion of pages containing advertisements. In broadcasting, it is often measured by advertising time, such as seconds or minutes of commercial breaks per hour. In digital media, it can be based on ad impressions, fill rate, or advertising revenue share. The metric helps publishers and broadcasters plan layouts and schedules, optimize pricing and inventory, and assess advertising density for research, transparency, or regulatory compliance.

Usage of the term varies by context and organization. It is a descriptive concept rather than a single standardized index, and in some discussions it is closely related to or contrasted with terms such as advertising load (mainoskuormitus). Variants of the concept may emphasize different dimensions of ad content, such as visibility, duration, or revenue impact. The etymology is straightforward: ilmoitus means advertisement or notice, and mittari means meter or gauge.
