Thanks to the advent of technology, the average human attention span has decreased from 12 seconds to a startling eight seconds — shorter than that of little goldie.

On-demand is a key driver of declining attention spans. Consider that Gen Z has never known a time before the Internet and cell phones.

If they want a ride, Uber is always ready to take them. If they want something to eat, Mr Delivery offers them a range of cuisines to choose from and will deliver to their doorsteps. And when they want to watch something, they can tune into Netflix, Disney+, Showmax ... the list goes on.

Moreover, consider that between 6 000 to 10 000 advertising messages hit us daily — across multiple platforms, devices and channels — and it's near impossible to internalise all these messages.

This exponential growth of advertising, shortening attention spans, on-demand culture and digital fatigue means that media consumption habits are evolving. People are tuning in, zoning out, skipping and switching over. This cocktail of factors has severe implications for the advertising industry, which derives its value from consumer attention.

And it begs the attention, how effective are our advertisements, really? And are we measuring what matters to enable effective planning?

If no one pays attention to your ad, there is no way it can influence a sale. So now we're asking, "Does an ad on TV garner more attention than that same ad online? Do people tune in longer to a radio ad than a YouTube ad? In other words, does an impression delivered on one channel, offer the same attention as an impression reported on another?"

The goldfish economy

This changing paradigm has been dubbed the 'attention economy' and attention metrics have risen to the fore.

Media currencies remain mainly concerned with impressions, reach and 'opportunities to see', which offer a myopic view of value delivered. Attention metrics offer an alternative for media planners and owners to adapt their strategies in line with the dynamic nature of digital media consumption, enabling brands to measure and optimise their efforts for meaningful engagement rather than mere exposure.

OOH as an attention medium

According to the Kantar Media Reactions Survey 2022, while marketers are increasingly using online channels, local consumers are showing the highest ad receptivity towards Out-of-Home and Digital Out-of-Home, a medium surpassed only by sponsored events.

This is because Out-of-Home is viewed as a non-intrusive medium. Moreover, Digital Out-of-Home is evolving to capture audience attention through creative, dynamic and data-driven strategies. The integration of technology, interactivity and real-time content adjustments is reshaping how advertisers approach Out-of-Home campaigns and engage viewers effectively.

Within this context, the Outdoor Measurement Council has introduced the Visibility Adjustment Calculation (VAC), which is essentially a move towards an attention metric.

VAC assesses the likelihood of an advertisement being seen by an audience — a key aspect of attention. It provides a more accurate representation of the effective reach of an ad by factoring in visibility and ad exposure time, rather than just counting the number of times an ad was served or reporting on the footfall and traffic around a certain location.

So why be excited about this move?

1. More granular data inputs for programmatic

Visibility Adjustment Calculation allows the measuring of digital impressions at a far more granular level, calculating audience delivery on ad play level by hour of the day, for each day of the week — a programmatic essential. By applying digital impressions at Visibility Adjustment Calculation level across our programmatic platforms, we're now able to elevate our reporting on programmatic buys.

2. Share of voice / share of time

Digital Out-of-Home audience planning and delivery have always been challenging to quantify due to differing ad rotations, the number of advertisers in a loop and ad lengths. This is further complicated by differences in loop structures across media owners.

In the past, media owners and advertisers would assume that a spot on a one-in-10 loop delivers 10% of the screen audiences, as an example. However, this approach does not consider that screen and ad-play impressions vary based on spot length time and dwell time. In other words, on a share of time model, a 15" will have more viewability than a 5" ad.

This is especially important for loop-based planning and reporting.
