An in-feed video ad is a YouTube ad that appears as a thumbnail image with a headline and a line or two of text, in places where people browse for something to watch: YouTube search results, the home feed and the list of related videos beside the one being watched. The video plays only when someone clicks to watch it. Google previously called this format a video discovery ad.
How in-feed video ads work
Unlike a skippable in-stream ad, which interrupts a video someone already chose, an in-feed ad asks to be chosen. It looks similar to the ordinary videos around it, with a small “Sponsored” label. A click usually opens your video on its YouTube watch page, where it plays like any other upload.
You are charged when someone clicks to watch, so the cost is closer to a cost per view than a cost per impression. Thumbnails seen and scrolled past cost nothing.
At the time of writing (October 2026), you can run in-feed placements through video campaigns with a views or engagement goal, and through Demand Gen campaigns, which mix in-feed, in-stream and Shorts inventory with Discover and Gmail. Google decides the exact mix in Demand Gen unless you limit the channels.
The video must be uploaded to a YouTube channel, public or unlisted. You supply a headline and description, and you can pick the thumbnail.
Why it matters
People who click an in-feed ad have chosen to watch, which tends to mean longer viewing than an interruption ad. That suits content that earns attention: a how-to video, a product demonstration, a walkthrough of a property, or an explainer for a service that needs some thought before buying.
For a UK business, a useful case is search. Someone typing “how to fit a loft hatch” or “what happens at a dental implant consultation” into YouTube is already looking for that answer. An in-feed ad with a genuinely useful video can put your business in front of them at the start of their research, at a modest cost per view.
It is less suited to quick, direct-response sales. Most people who watch on YouTube do not leave the platform straight away, so judge in-feed ads on what follows: later branded searches, remarketing audiences and conversions over a longer window.
Common mistakes
- A thumbnail that promises one thing and a video that delivers another. Viewers leave within seconds and the campaign learns little.
- Reusing a short interruption ad that assumes a captive viewer. In-feed viewers chose your video and expect substance.
- Judging success on views alone, without looking at how much of the video people watched.
- Letting a Demand Gen campaign spend across all channels without checking which ones produced results.
How to act on it
Pick one or two videos that answer a real question your customers ask. Write a headline that names that question plainly and choose a thumbnail with a clear face, product or result. Run them with a views or engagement goal, then check average watch time and audience retention in YouTube Analytics after the first fortnight.
Build a remarketing list of people who watched, and follow up with search or display ads. If you want a plan for where YouTube fits alongside search, I run YouTube advertising campaigns for UK businesses with that in mind.
