The Moments of Truth

The Moments of Truth is a landmark three-stage research project that proves how the use of contextually relevant messaging in digital Out of Home will increase its effectiveness by an average +17%.

The pioneering study is a cross-industry collaboration between Clear Channel, JCDecaux UK and Posterscope which demonstrates the power of relevancy in Out of Home, showing increased metrics across consumer brain response, ad recall, brand / creative rating, and sales response.

Stage 1


Conducted by leading Neuroscience research company, Neuro-Insight, stage one consisted of using the established Neuroscience technique of Steady State Topography (SST), monitoring the brain response of 160 participants during exposure to either contextually relevant (test) or non-contextually relevant (control) digital Out of Home advertising on a full-size portrait DOOH screen.

The results revealed an average increase in brain response (test vs. control):

Relevant Moment

An average +12% increase in brain response when displaying a ‘brand’ or ‘product’ communication at the most relevant moment vs. a less relevant moment.

Relevant Content

An average +18% increase in brain response when displaying content that was relevant using either the location, the weather, the time or a live update as the stimulus trigger, with an explicit call out to the relevancy - e.g. it's raining.

Relevant Moment + Relevant Content

An average +32% increase in brain response when displaying the most relevant content with an explicit call out at the most relevant moment.

Stage 2

Ad Recall

Using online webcam eye-tracking software, through partner ResearchBods, 280 respondents viewed a video ‘walk-through’ of an indoor shopping mall with six digital Out of Home screens each featuring a different brand’s advertising. The video featured a mixture of contextually relevant (test) and non-contextually relevant (control) advertising displayed on the screens.

The research monitored the duration of ad fixation (for advertising at relevant moments and with relevant content), while a post exposure questionnaire showcased average improvements of (test vs control):

+ 6%

Time spent looking at advert


Spontaneous ad awareness


Average creative rating

Stage 3

Sales Effect

The final stage of the research saw a meta-analysis across multiple effectiveness studies, each of which monitored the link between in-store sales and the use (or absence) of digital Out of Home advertising.

The comparisons determined that advertisers applying relevant content at relevant moments in the real world drove a consumer action versus a traditional singular digital Out of Home creative approach.

The average sales uplift (test vs. control):


Standard DOOH vs. No OOH
