The Types of Video Advertising (and When to Use Each)

Sorting video ad formats by placement, meaning where the ad runs and how it behaves, is the shortcut that makes every other decision easy. Length is the wrong first question. I have sat on scoping calls where a team argued for a week about 15 versus 30 seconds when the actual choice was whether the spot belonged in a YouTube pre-roll slot or in a muted feed that a thumb flicks past in half a second. The ad industry files formats this way too: the IAB’s placement framework splits them into in-stream, accompanying content, interstitial, and standalone. So when a media plan lands in my inbox, the first thing I do is tag every line with its placement, because that is what tells me what the creative has to survive.

The stakes keep climbing. Digital video, meaning CTV plus social plus online video, passed linear TV in US ad spend for the first time in 2024 and took the majority of TV and video money in 2025, per the IAB. Below is every type I work with, what it is, and when I reach for it. The table gives you the whole map in one glance, and the sections after it are where I get specific.

In-stream: ads inside video someone chose to watch

In-stream plays before (pre-roll), during (mid-roll), or after (post-roll) video the viewer actually opted into, sound on and the player in focus. It splits two ways, and I pick between them by what I need the ad to do. Skippable in-stream can be skipped after five seconds and you pay only on a real watch or interaction (CPV), which makes the format filter for interest on its own, so it is strong for storytelling and reach. Non-skippable runs the full length, up to 60 seconds on YouTube, billed per impression, and I use it when the whole message has to land and a skip would gut it. The trade I flag to clients: skippable buys efficient attention from people who chose to stay, while non-skippable buys certainty at a higher cost per completed view.

Bumper: six seconds, no skip

A bumper is six seconds or shorter, non-skippable, and billed per impression, and the constraint is the entire point. One image and one line, repeated for frequency, is all it can carry. I have never once seen a bumper campaign work as a standalone; it earns its keep stacked on top of a longer format, jogging the memory of people who already saw the story. When a client asks me to explain a product in six seconds, I talk them out of it.

Out-stream: video where there was no video

Out-stream ads auto-play muted inside an article, between paragraphs, or in a social feed, with no dedicated player. They fire when they scroll into the viewport and often float as a small player while you keep reading. They stretch reach well past video-first sites, which is the appeal, but the number I make every client check is viewability. Because these play during a scroll, real completion and viewability run lower than in-stream, so a tempting out-stream CPM can hide the fact that almost nobody watched. Design for sound-off, put your hook in the first second, and read the viewability rate before you read the price.

In-feed: earning the click in a moment of discovery

In-feed video (on YouTube, once called Discovery) is a thumbnail and a headline shown where people are already hunting for something: search results and the home feed. The viewer clicks to watch, so this is pull rather than interruption, and the people who click are self-selecting, which is why in-feed tends to earn longer and more engaged views than a forced pre-roll ever will. I lean on it for consideration, when someone is close enough to actively choose your video over the ten sitting around it.

OTT and CTV: the big screen, and the difference that matters

Getting these two words straight is a fast way to sound like you know the channel, so I never blur them. OTT is the delivery method, video sent “over the top” of the open internet to any device. CTV is the device itself, an internet-connected television or a streamer like Roku or Apple TV. Every CTV impression is OTT, but OTT also covers phones and laptops. CTV ads run full-screen with the sound on and mostly cannot be skipped, and they post completion rates broadcast buyers only dream about, which is why I watch more brand money move there every year. Make it for the living room: big and sound-designed, with no tiny on-screen text that dies at ten feet.

Social video: vertical and built for a muted feed

Native in-feed formats across Meta, TikTok, YouTube Shorts, Snap, and LinkedIn are mostly vertical (9:16), built for sound-off autoplay, and won or lost in the first second or two. This is now the single largest digital video category by ad spend, with the IAB putting social video around $27 billion in 2025, so I give it real weight in any plan instead of treating it as the leftover cut of a TV spot. If you want the mechanics of framing for these, I wrote up the best video formats and aspect ratios separately, and for inspiration the galleries of Instagram video ad examples and digital marketing video ad examples show what lands in the feed.

Shoppable video: from watch to cart

Shoppable video puts clickable product tags and in-session checkout right inside the player, so a viewer buys without ever leaving the video. YouTube runs product feeds inside video ads across mobile, desktop and CTV, and TikTok Shop is the loudest example going. It sits at the bottom of the funnel and pays off hardest for ecommerce and direct-to-consumer brands, where the gap between “I want that” and “it is bought” is the whole game. I would not point brand-awareness money here, but for a catalog with real demand behind it, shoppable converts like little else.

How to choose: match the format to the funnel

The wrong format for your goal wastes spend even when the creative is excellent, so I map placement to funnel stage before I brief a single frame.

One principle saves more money than any targeting tweak: the creative has to match the format, not the other way round. A bumper wants one crisp idea and CTV wants the big screen with the sound on, and neither survives being fed the same horizontal 30-second spot stretched across seven placements. That stretch is the most common and most expensive mistake I get called in to undo. The category you sell in tightens the brief further, which is why we keep separate breakdowns for automotive video advertising and financial services advertising. Regulated categories go further still, and health product advertisements clear a higher bar of proof before they ever run.

At Moonb I cut format-native creative, the right version for each placement, as an embedded creative team, so a media plan runs on the right file everywhere instead of one spot forced into shapes it was never framed for. If that is useful, see how Moonb works.
