Reddit has changed what advertisers can buy on the platform, and the new unit is fifteen seconds of someone actually watching.
The company launched 15-second Engaged Video Views this week, in public beta for advertisers worldwide. It works as both an optimisation goal — what Reddit's ad system aims for — and a billing option, so brands can pay against sustained watch time instead of an impression or a two-second glance.
The counting rules
They're simple enough. If your video runs 15 seconds or less, a completed view counts. If it's longer, the view lands once someone has watched at least 15 seconds.
That threshold sits well above Reddit's existing 6-second goal, which isn't going anywhere. During the beta, brands can split-test one against the other — a sensible admission that more watch time isn't automatically better for every campaign.
Who it's for
Reddit is pitching this at creative that needs room to breathe: trailers, product demos, testimonials. The argument makes sense. A six-second view tells you almost nothing about whether anyone absorbed a two-minute demo, and paying for the short signal rewards the wrong thing.
The company says early tests delivered an average 51% lift in 15-second view-through rate and a 71% lift in completion rate. Those are Reddit's own beta numbers, measured against campaigns optimised for something else, with no outside verification attached. Treat them as a direction, not a promise.
Everyone is redefining the view
This lands in the middle of a broader shift. Platforms spent 2026 quietly rewriting what a video view is and how it gets counted — YouTube changed its own methodology in August.
For years advertisers bought video against thresholds so low the number barely meant anything. Pushing the bar to fifteen seconds closes some of the gap between what a platform reports and what a marketer actually wants, which is a person who stuck around long enough to hear the point.
There's an obvious trade. You get fewer counted views, and each one costs more. Chasing reach for an awareness push? Probably the wrong buy. Running a demo where the first six seconds explain nothing? Probably the right one.
The real test
What matters is whether campaigns bought this way move business results, not just view metrics. A metric that only improves the metric hasn't done much for anyone. The split-test option makes that comparison easy to run, and advertisers on Reddit video have a cheap window to find out while the beta is open.
