Brussels – Alarmed by the low signal to digital noise ratio (SdNR) measurements online, marketing researchers are growing concerned that their content creation efforts are being ignored.
Signal to Digital Noise (SdNR) is the measure of the level of a desired marketing signal to the level of online digital noise. SdNR is defined as the ratio of signal power to the digital noise power, often expressed in decibels.
Digital noise has steadily been on the increase as everyone, and their brother, thinks they can create their own blog posts, webinars, YouTube videos, social media posts, and podcasts. But that ever growing online barrage of home-grown content is only drowning out the marketing signal.
