How a video view audience works
When a video of yours runs on Facebook, Instagram or the Audience Network, Meta records how much of it each person watched. A video view audience turns that record into something you can target: everyone who reached a chosen watch threshold on a chosen video, within a chosen lookback window.
Two settings decide how large and how warm the list is. The threshold decides how much interest someone had to show — a few seconds of play, a ThruPlay, or a share of the video such as a quarter, a half or nearly all of it. The lookback window decides how recently. Meta rebuilds the list continuously, so a person who watched outside the window drops out without you doing anything.
Because it is built from what happened inside the app, it does not depend on your pixel firing correctly or on a visitor ever reaching your website. That is the practical difference between it and a website custom audience.
Why video view audiences matter
Most advertisers have far more people who watched a video than people who visited the site. Video is cheap to distribute and easy to consume on a phone, which matters in Nepal where the majority of feed time happens on mobile data. So a video view audience is often the largest genuinely warm list a small business can build, and the only warm list available before a website has any real traffic.
It also lets you sequence a message. The first ad earns attention, the second ad speaks to people who already gave you some. That second ad can skip the introduction and go straight to the offer, which usually buys a cheaper result than talking to strangers.
Common mistakes with video view audiences
The biggest one is treating the shortest threshold as intent. Video autoplays in the feed, so a viewer who scrolled past has technically watched. Building your warm audience from that group gives you a big list of people who never chose to watch anything, and the performance shows it.
The second is letting the source go stale. The list only grows while the video is still being served, so when the campaign that produced the views is paused, the audience quietly shrinks to nothing over the lookback window. People notice weeks later, when delivery has already collapsed.
The third is stacking it on top of every other warm list without checking who is in both. The same person can sit in a video audience, an engagement audience and a website audience at once, and you end up bidding against yourself.
How to act on it
Choose the threshold by asking what a person had to do to be on the list. A ThruPlay or a substantial share of the video is a real signal; the shortest option is not. Then set the window to something close to how long your buying decision actually takes — days for a food order, weeks or months for an education consultancy or a property.
Keep at least one video running for reach so the list keeps refilling, and use exclusions so anyone who has already converted stops seeing the follow-up. If the numbers of people are small, combine several videos into one audience rather than running many thin ad sets. This is ordinary Meta retargeting discipline, and it applies whether the source is a video, a form or a page view.
