What Are LinkedIn Video Ads, and Why Use Them?
LinkedIn video ads are sponsored videos that play in the LinkedIn feed. Per LinkedIn's video ads page, they autoplay with the sound muted by default, which is why captions matter more here than almost anywhere. LinkedIn says video ads drive 3x higher engagement than non-video formats.
For B2B, the job is simple to say and hard to do: stop a busy professional in the feed, make one clear point without sound, and earn the click. This page covers the specs, the length, the pricing and the creative, then the services that make them.

How Long Should a LinkedIn Video Ad Be?
LinkedIn recommends 15 to 30 seconds, so the video qualifies for every placement. Anything under 30 seconds loops until it reaches 30 seconds of playback.
At about 140 spoken words a minute, a 30-second ad is about 70 words. That is one hook, one point and one call to action. Longer explainers can still run; they just reach fewer placements.

How LinkedIn Video Ads Get Priced
Per LinkedIn's pricing help page, ad cost is set by an online auction against other advertisers reaching a similar audience, and relevance can lower what you pay. How you are charged depends on your bidding strategy. From the bidding strategies page:
| Bidding strategy | How it works | How you are charged |
|---|---|---|
| Maximum delivery | Machine learning bids for you and aims to spend the whole budget | Impressions (CPM) |
| Cost cap | You set a cost per key result as a benchmark | Impressions |
| Manual bidding | You set the bid for a key result | Clicks, impressions, video views or sends, depending on the objective |
The media spend is separate from making the video. For what the video itself costs, see how VideoRep pricing works.
How to Make a LinkedIn Video Ad More Engaging
Caption everything. The ad starts on mute, and LinkedIn's video ads page strongly recommends captions so the message is clear from the first frame.
Say the point early. The first line has to work with the sound off and before the scroll. Lead with the problem your buyer recognizes.
Keep it short. LinkedIn notes that shorter videos are often effective for capturing attention.
Show a person. One presenter across the campaign gives the feed a face your buyers start to recognize.
Write several hooks. One read can carry two or three openings, so you can test them without a second shoot.
Do Talking Head Ads Beat Animated Ads on LinkedIn?
We don't have a LinkedIn-only test to point to, so here is what our own ads show on other paid feeds. For Syroscape's client Charity Auctions, three presenter-led Meta ads ran against the existing static creative on the same audience and offer, and the founder reported about a 72% increase in conversions. For Fyntra, presenter ads did 4x better than the AI-only ads they replaced.
Animation still has a place: when the product is abstract or hard to film. When the ad has to earn trust from a stranger, a real person is the safer bet.
LinkedIn Video Ad Examples
More guides on ads and channels are in the Learning Centre. The clearest LinkedIn example we can show is Workvivo by Zoom. Its 2026 launch videos and an IT-persona batch were briefed to run on LinkedIn and Meta, with me as the presenter, filmed to their script and handed over as clean files for their team to cut.
| Example | Format | Why it works on LinkedIn |
|---|---|---|
| Workvivo HQ launch | Lo-fi day-in-the-life videos | Looks native to the feed, with a person front and center |
| Workvivo IT-persona batch | Presenter reads to one buyer role | Speaks to a single job title, the way LinkedIn targets |
| Syroscape for Charity Auctions | Presenter ads with vertical cuts | The same creative, cut for every ratio LinkedIn accepts |
