CPV (Cost Per View)

CPV, or cost per view, is a pricing model for video advertising in which an advertiser pays for each counted view of an ad rather than for impressions, clicks, or conversions. Divide the spend on a video campaign by the number of counted views and you get the CPV — the average cost of buying one view. It is the natural currency for video, because the goal of a video ad is usually to be watched, and CPV ties the cost directly to that outcome. The wrinkle, and it is a large one, lies in the word "view." A view is not a universal, fixed unit; each platform sets its own threshold for what counts. So CPV is simple arithmetic sitting on top of a definition that quietly varies, which means the headline number can mean very different things depending on where the campaign ran.

Understanding CPV therefore means understanding the view definition behind it, because that definition decides what you are actually buying. On some platforms a view is counted after a viewer watches a certain number of seconds; on others it is a percentage of the video completed; on others a view registers almost immediately, after just a second or two of playback, sometimes whether or not sound is on. Two campaigns can report the same CPV while delivering completely different amounts of real attention, because one platform's "view" demands sustained watching and another's barely demands any. That is why CPV cannot be read at face value or compared across platforms without first asking what each one means by a view. The cost is only as meaningful as the unit it is paying for.

CPV sits alongside the other cost-per metrics and is distinguished by what triggers the charge. CPM (cost per mille) charges per thousand impressions — per thousand times an ad is served, watched or not. CPC (cost per click) charges only when someone clicks. CPV charges per counted view, a middle ground for video: more engaged than a mere impression, less committed than a click. Choosing CPV says you care about the ad being watched, not just shown, and not necessarily acted on. For video, that often makes CPV the most fitting unit — but only if the underlying view threshold genuinely reflects the attention you want. CPV's value over CPM is precisely that it ties cost to watching rather than serving, which collapses if the "view" is defined too loosely to mean watching at all.

The view-definition trap is the central thing to manage with CPV, and it is where comparisons go wrong. Because platforms define a view differently — a few seconds here, a meaningful percentage completed there — a low CPV on a platform with a loose definition can be worse value than a higher CPV on one with a strict definition, since you are paying for thinner attention. Comparing raw CPVs across platforms without normalizing for the view definition is comparing different things and will mislead. The honest approach is to read CPV always together with its view threshold, and to back it with completion and engagement measures — how much of the video was actually watched — so you judge attention, not just a counted event. CPV is a useful video currency only when you know exactly what a view means in each place you buy it.

Using CPV well means never reading the number without its definition. Before comparing CPVs or judging a campaign cheap or expensive, find out precisely what each platform counts as a view — how many seconds or what percentage of completion — and normalize accordingly, because a CPV is only meaningful against its threshold. Pair CPV with completion-rate and engagement metrics so you measure attention actually delivered, not just views nominally counted, and tie it back to whatever outcome the video is meant to drive. Choose CPV when watching is genuinely the goal and the platform's view definition is strict enough to mean it; choose CPM when reach matters more, or CPC when action does. Read this way, CPV is a clean way to buy video attention. Read carelessly, it flatters loose definitions.

The failures almost all trace back to ignoring the view definition. Advertisers chase the lowest CPV across platforms without realizing the cheapest one counts a "view" after a second or two, so they buy a flood of glances and call it engagement. Others compare CPVs head to head as if the unit were standard, treat a low CPV as proof of efficient attention, or stop at the view count without checking how much of the video was watched. The discipline is to always pair CPV with its view definition, normalize before comparing, back it with completion and engagement data, and remember that the goal is watched video, not counted views. A view is only worth what it represents, and CPV is only as honest as the threshold beneath it.

CPV (cost per view) — the cost of one counted video-ad view — is only as meaningful as each platform's differing definition of a view, so it must always be read against that threshold and completion data.
