Vertical video runs on almost every social platform now, and the audience keeps climbing. TikTok alone reported around 17 million monthly active users in Japan back in August 2021, and the figure has grown since. Add YouTube Shorts, which passed 1.5 billion logged-in monthly users worldwide, plus LINE VOOM and Instagram Reels, and the total vertical audience only points one way.
Two worries still hold advertisers back: "few people actually buy after watching," and "we do not know how to make the creative." Both are out of date. This guide lays out six concrete strengths of vertical video ads, then shows a low-effort way to produce your first one and the cases where the format does not fit.
People do buy after watching
The first worry collapses against the data. A survey by TORIHADA, a video and influencer marketing firm, found that about one in three TikTok users had bought or signed up for a product or service after seeing it on TikTok. The categories ran wide: apps and games led at 34%, followed by groceries at 34%, then affordable skincare, makeup, daily goods, and apparel. Vertical video moves a broad range of products, not a narrow niche.
Shopping features keep expanding
The path from watching to buying also keeps getting shorter. YouTube lets creators link the products they show to a shopping function, so viewers can buy mid-video. TikTok Shopping, already live across parts of Asia, points the same direction. As these features mature, more purchases will start from a vertical video.
The audience reaches far beyond teens
"Only teens and twenty-somethings watch, so this is not for us" misreads the data. Teens and twenties do make up a large share, but TikTok's age distribution runs through people in their thirties, forties, and fifties, with an average user age around 34 in one Hakuhodo study. LINE VOOM, which serves short vertical video, also reaches a wide age range across men and women. A growing audience that spans ages and genders makes for an appealing place to advertise.
It conveys texture and real use that a still cannot
On most placements, a vertical ad fills the screen, so a short clip can still carry a lot of information. That lets you show the texture and use of a product that a static image leaves out, which suits anything whose value takes explaining. For cosmetics, a clip of the product in use conveys the feel and texture. For food, footage of cooking and eating sells the taste and the sizzle, the appetite-triggering detail that copy struggles to land.
You do not need a heavy production
Production tends to get postponed because planning, shooting, and editing sound like a mountain of work. Vertical video lowers that bar for two reasons: the short runtime keeps shooting and editing light, and these platforms accept simple, UGC-style clips because that is what fills the feed. Once you have a template, a single edit can take under 30 minutes.
For planning, pin down the must-say points (use case, what makes it different, price), build a structure that holds your target to the end, and put real effort into the first few seconds, since viewers decide there whether to skip. Most vertical ads run 20 to 40 seconds, so set a rough length and trim in the edit. For shooting, a phone is enough, and phone footage often performs better because it reads as familiar. Film in good light and keep other brands' logos out of frame. For editing, intuitive tools such as Canva handle drag-and-drop creation from templates, and each platform offers its own free editor. If you outsource, a production company suits quality and crowdsourcing suits budget, with turnaround often inside a week. Keep your text inside each placement's safe zone so the platform's own interface does not cover what matters.
One winner travels across platforms
When a creative performs, you can often run it on other platforms with little change. A clip that wins on TikTok, LINE VOOM, YouTube Shorts, or Instagram Reels tends to travel, because the viewing experience and the formats sit close together. If one platform is working, test the others.
One placement breaks the pattern: Pangle, the mobile ad network that runs through TikTok into games, comics, and other apps. There, the ad can get cropped to a square or shown in a tiny slot, and you cannot control the format, so a full-screen vertical does not carry over. For Pangle, rebuild the creative around its specs instead of reusing one as is.
Where to be careful
Three cautions matter before you scale. First, video built in a platform's own editor often will not travel: a clip made in the TikTok Creative Toolkit, for example, cannot move to other platforms as is, so avoid those tools when you plan to cross-post. Second, check the rights on every image and BGM track. Shoot your own images or buy ones licensed for ads from a stock site such as PIXTA, and use royalty-free BGM or licensed tracks from a service such as Audiostock, reading the terms either way. Third, the format does not fit every product. TikTok's audience is broad, but the share over 60 stays low, so acquiring older customers there is hard, and the casual, organic tone can clash with a brand that needs a more premium image.
Starting now puts you a step ahead
The vertical audience will keep growing, and with it the weight of advertising there. You do not need polished planning or a full set of footage to begin. Pin down the must-say points, shoot something on a phone, and put your effort into the first few seconds. Getting in early, while the format is still open, is what puts you a step ahead of competitors who keep postponing it.
