Meta is testing Aggregated View Time, a product that measures and optimises the total time a person spends with a brand across a week, rather than judging each video impression on its own. The product is in alpha.
Meta described the test at its Brand Building Summit on 16 October, alongside the general availability of Ads Super Burst and a test of First Impression Ads on Facebook. It gave no date for wider availability and named no advertisers in the alpha.
Why Meta Is Moving Away From Single Views
Meta's argument starts with television. The digital media industry, it says, has treated a long video view as a sign that an ad worked because that is how television worked. Short-form video is watched differently.
Meta's own example is a brand seen for two seconds in a feed, one second the next day and two more seconds on Thursday. Counted one impression at a time, none of those views looks long. Counted across the week, they add up to five seconds with the brand.
According to Meta's research, five seconds of attention added up over a week drove 32% more offline sales than one continuous five-second view. Meta says independent industry research found the same pattern, with accumulated seconds predicting outcomes better than one long view.
The studies behind both findings are not identified in the announcement text, so neither can be checked against the underlying research.
The announcement also leaves the practical details open. It does not say which campaign objectives will support Aggregated View Time, whether it covers both Facebook and Instagram, or how advertisers join the alpha.
A Target for Delivery, Not Only a Report
Meta describes Aggregated View Time as a way to measure and to optimise. The second part matters more.
A new report changes what advertisers read after a campaign. An optimisation target changes what Meta's delivery system works toward while the campaign runs.
If delivery optimises for weekly time with a brand, the creative that performs best is the one that earns a few seconds again and again. A video that holds one long view would lose that advantage. How that system reads a video in the first place is a separate question, covered in Wilow's guide to how Meta's delivery system reads ad creative.
Where It Fits in Meta's Brand Pitch
Aggregated View Time is the measurement half of Meta's summit. Ads Super Burst and First Impression Ads sell concentrated, high-visibility moments. Aggregated View Time makes the case for many short moments over a week, and gives brands a way to count them.
The product also follows from Meta's own numbers on how its apps are used. Reels, the company says, make up more than half of all time spent on Instagram, which is the viewing pattern Aggregated View Time is built to measure.
Meta also opened the summit with a claim about brand results on its apps. Across a study of more than 1,000 global campaigns, it says, Meta built awareness 18% better than the average brand channel and drove a 73% lift in consideration. Aggregated View Time is how Meta proposes to measure that kind of result in short-form video.
Recap
What is Meta's Aggregated View Time?
Aggregated View Time is a Meta product in alpha that measures and optimises the total time a person spends with a brand across a week, instead of judging each impression on its own.
How does Aggregated View Time work?
It adds up the short moments a person spends with a brand over a week, such as two seconds one day and one second the next. Meta says five seconds accumulated this way drove 32% more offline sales than one continuous five-second view.
What does Aggregated View Time change for advertisers?
Because Meta describes it as an optimisation target as well as a metric, it could reward creative that earns attention repeatedly in short bursts. Meta has not given a date for availability beyond the alpha.
