YouTube Ads: Formats, Technical Specifications and Cost Per Format

by Francis Rozange | Apr 4, 2026 | Google Ads

Lede: YouTube Ads in 2026, a format ecosystem that no longer fits on a one-pager

YouTube is no longer “video advertising”. It is a stack of ten distinct ad surfaces, three billing models, and a creative pipeline that increasingly demands portrait, landscape, and square versions of the same idea. The platform crossed 2.7 billion logged-in monthly users in 2025, Connected TV viewing has overtaken mobile in the United States according to Think with Google’s CTV measurement studies, and Shorts inventory has expanded so aggressively that Google now reports it as a separate revenue line in its earnings calls.

The buying interface still looks similar. The economics underneath have shifted. “TrueView” was retired as a brand in 2024 and rebranded as Skippable in-stream. Demand Gen replaced Discovery campaigns and now serves YouTube, Discover, and Gmail with a single creative set. Video reach campaigns bundle bumper, skippable, and in-feed under one budget for efficient reach. VideoView campaigns optimize against viewable impressions rather than the old 30-second view.

The result: the same advertiser running “YouTube ads” today is buying across as many as ten different inventories with different rules per inventory. This guide maps every format, the technical specs Google enforces, the cost benchmarks observed by buyers in 2025-2026, and the 90-day playbook a new YouTube advertiser should run before scaling spend.

The YouTube ads ecosystem: ten formats, three billing models

Strip away the marketing names and YouTube ads sit on three economic foundations: cost per view (CPV), cost per thousand impressions (CPM), and cost per day or per hour (CPD/CPH) for guaranteed reservations. Every format inherits one of these.

CPV applies to skippable in-stream and to in-feed video. You pay only when a viewer watches at least 30 seconds (or the full ad if shorter) for skippable in-stream, and only when a viewer clicks the thumbnail and watches for in-feed. Google Ads Help defines this view threshold explicitly: skips and clicks-away before 30 seconds carry zero charge.

CPM applies to non-skippable in-stream, bumper ads, YouTube Shorts ads (in most placements), masthead when bought programmatically, and to video reach and VideoView campaigns. You pay per thousand served impressions whether the viewer engages or not.

CPD and CPH apply to the masthead reservation product sold by Google account managers. You buy a fixed slice of the YouTube homepage for a fixed window, no auction, no bidding signals.

The ten formats currently active on the platform: skippable in-stream, non-skippable in-stream, bumper ads, in-feed video (formerly Discovery), masthead, YouTube Shorts ads, video reach campaigns, VideoView campaigns, YouTube TV and Connected TV ads, and Demand Gen as the consolidated YouTube + Discover + Gmail surface. We cover each below.

Skippable in-stream ads: the workhorse formerly known as TrueView

Skippable in-stream is the format that made YouTube advertising a category. It plays before, during, or after a video. The skip button appears at the 5-second mark. The advertiser pays only on a qualifying view: 30 seconds watched, the entire ad if shorter than 30 seconds, or any interaction (click on the CTA, the companion banner, or the channel name).

The 2024 rebrand

Until 2024, Google branded this format “TrueView in-stream”. Search Engine Land documented the rebrand: TrueView was retired across product naming, the option moved into video reach campaigns and standalone “Skippable in-stream” line items, and the same auction logic carried forward. The name change was cosmetic. The economics did not change. Practitioners still talk about TrueView in agency rooms; the Google Ads UI does not.

Where it appears

YouTube watch pages on desktop, mobile web, the YouTube mobile app, the YouTube TV app on Connected TV devices, and Google video partners (a network of sites and apps outside YouTube proper). Advertisers can opt out of Google video partners at the campaign level, and most performance buyers do.

Creative specs

Recommended resolution is 1920×1080 (1080p) at 16:9 for landscape. For mobile-first delivery, supply a 1080×1920 (9:16) portrait variant and a 1080×1080 square. Accepted file formats include MP4 (H.264 codec recommended), MOV, AVI, WMV, MPEG-4, and WebM. Maximum file size is 256 GB or 12 hours of duration, whichever comes first. Practical creative duration runs 12 to 60 seconds for performance work, with 15 and 30 seconds the most common cuts. Audio is mandatory: a silent track is acceptable, but no audio track triggers rejection.

Cost benchmarks 2026

Average CPV for skippable in-stream sits at $0.03 to $0.10 in 2026 across major English-speaking markets, down from the $0.10 to $0.30 range that dominated 2022-2023 reporting. The compression is real: Tinuiti’s quarterly benchmarks show CPV declines of roughly 35% year over year on the accounts they manage, driven by Shorts inventory expansion and increased competition for view-through optimization. Top performers in low-competition verticals (entertainment, music, gaming) hit $0.02 to $0.03. Premium verticals (finance, legal, B2B SaaS) still pay $0.08 to $0.20.

CPM equivalents land at $5 to $15 for U.S. campaigns, $4 to $10 for Western Europe, $1.50 to $4 for India and Southeast Asia. The Strike Social analysis of $14.3 billion in YouTube ad spend, widely cited in Search Engine Journal coverage, places the global average CPM near $9.30 for standard formats, with small and mid-market advertisers averaging closer to $8.

Non-skippable in-stream ads: the 15-second commitment

Non-skippable in-stream forces full message delivery. The skip button never appears. Maximum duration is 15 seconds (Google reduced this from 20 seconds in 2020 to standardize the format globally). Billing is CPM. You pay on impressions whether the viewer leans forward or away.

Where it appears

Same surfaces as skippable in-stream: watch pages on desktop, mobile, app, and Connected TV. The format is most often used inside video reach campaigns and Demand Gen alongside skippable and bumper, rather than as a standalone line item.

Creative specs

Resolution: 1920×1080 (16:9) recommended; vertical variant at 1080×1920 (9:16). Duration: hard cap at 15 seconds. File formats and size limits match skippable. Critically, the first three seconds carry the full burden: there is no skip risk, but viewer attention is a finite resource, and click-through depends on the hook.

Cost benchmarks 2026

CPM ranges from $8 to $20 in the U.S., $6 to $15 in Western Europe. The premium over skippable reflects guaranteed view: advertisers pay more per impression because the viewer cannot escape. Q4 retail competition pushes non-skippable CPM 30 to 50% above the annual average. January and February typically deliver the cheapest non-skippable inventory of the year.

Use case: brand storytelling in 15 seconds when the message must be delivered intact. The format is a poor fit for direct response (CPM math rarely beats CPV-billed skippable for click-driven goals).

In-feed video ads: the format formerly called Discovery

In-feed video appears as a thumbnail with a headline and short description in three places: YouTube search results (above and inside organic results), the YouTube mobile homepage feed, and the “Up next” related videos panel on watch pages. Until 2022, Google called these “Discovery ads”. The rename to “in-feed video” happened alongside the launch of Demand Gen, which absorbed the broader Discovery campaign type.

How it bills

CPV. The advertiser pays only when a user clicks the thumbnail and the video begins playing. This makes in-feed the highest-intent format on the platform: every paid view came from an explicit click. Click-through rates on the thumbnail itself are not billable.

Creative specs

Video resolution: 1280×720 (720p) minimum, 1920×1080 (1080p) preferred. Aspect ratio: 16:9 horizontal or 9:16 vertical. Custom thumbnail at 1280×720, JPG or PNG, under 2 MB. Headline text: up to 100 characters, but the first 25 characters are what mobile users see without truncation. Description: up to two lines of 35 characters each on most mobile placements. Practical duration: 10 to 30 seconds for click-to-watch flows, longer for educational content where the click signals serious intent.

Cost benchmarks 2026

CPV averages $0.05 to $0.20, with the median near $0.10 for mid-market advertisers. CPM equivalents at $3 to $10. Click-through rate on the thumbnail benchmark: 1 to 3% is typical. View-through rate (full watch) on clicked ads: 35 to 50%, much higher than skippable in-stream because the user opted in.

In-feed converts roughly 2.3x better than homepage placements for the same advertiser, according to Search Engine Journal placement studies. The reason is straightforward: a user typing “best DSLR 2026” and clicking your camera ad has demonstrated active intent. A user passively scrolling the homepage has not.

Bumper ads: six seconds, no skip, maximum reach

Bumper ads run 6 seconds maximum, never less than 5. No skip button. Billed CPM. The format launched in 2016 specifically to attack the brand-recall problem on mobile: short attention windows, high frequency, and a creative discipline that forces a single idea per unit.

Where it appears

All in-stream surfaces (watch pages, app, CTV) and inside Shorts where the advertiser opts into the broader inventory. Bumper is rarely sold standalone in 2026. Most bumper spend now flows through video reach campaigns where Google decides the bumper share against a target reach goal.

Creative specs

Duration: exactly 6 seconds, no exceptions. Resolution: 1920×1080 (16:9) or 1080×1920 (9:16). File format: MP4 H.264 strongly recommended. Audio track required even if silent. The creative discipline matters more than the technical specs: 6 seconds is roughly 18 to 22 spoken words. A wordy bumper fails. The strongest bumpers carry one logo, one product shot, one line of copy, and one CTA frame.

Cost benchmarks 2026

CPM ranges from $5 to $10 in the U.S., $4 to $8 in Western Europe. The lowest cost-per-impression among forced-view formats. Tinuiti benchmarks show bumper delivering 2.5 to 3x more impressions per dollar than 15-second non-skippable for the same gross spend, which is why bumper anchors most reach-led plans.

Sequencing logic

Bumpers work best paired with longer formats. The pattern that consistently outperforms in measured studies: bumper for awareness across week 1-2, skippable in-stream for engagement across week 2-4, in-feed video for conversion across week 3-6. The bumper primes the audience; the longer formats convert primed viewers at lower CPV than cold audiences.

Masthead: the homepage takeover

The masthead is the banner at the very top of the YouTube homepage, on desktop and on the mobile app. It autoplays muted for up to 30 seconds. It includes a video, a headline, a tagline, an optional companion side panel on desktop, and a CTA button. It is YouTube’s premium reservation product.

How it bills

Two purchase models. CPM masthead: a fixed volume of impressions over a fixed window, available globally through Display & Video 360 or via a Google account manager. CPD masthead: 100% share of voice for a reserved day, sold only through Google reps. The U.S. desktop and mobile homepage masthead for a single day starts at roughly $1 million in 2026 list pricing, with peak periods (Super Bowl week, Cyber Week, major product launches) running higher. International markets price at a fraction of U.S. rates: a single-day masthead in Mexico, Brazil, or Indonesia can run in the low six figures.

Creative specs

Video resolution: 1920×1080 (16:9) for desktop, 1080×1920 (9:16) for vertical mobile masthead. Duration: 15 to 30 seconds. Companion image (desktop side panel): 300×60 pixels, JPG or PNG, under 150 KB. Headline: 25 characters maximum. Tagline: 35 characters maximum. CTA button text: 15 characters. The companion banner is desktop-only.

Who buys it

Major brands at peak product moments. Apple iPhone launches. Console launches. Theatrical releases. Election-period political advertisers in markets where political ads are permitted. The masthead is a brand instrument, not a performance instrument. Reach is enormous (the U.S. desktop homepage serves 40 to 60 million logged-in viewers per day) but CPA tracking on masthead is notoriously noisy.

YouTube Shorts ads: vertical, mobile-first, fastest-growing

Shorts are YouTube’s TikTok response. The Shorts feed launched globally in 2021. By 2024, Shorts viewing crossed 70 billion daily views. By 2025, Shorts inventory had expanded so aggressively that Google began breaking it out as a distinct line in advertiser reporting. Shorts now accounts for roughly 22% of YouTube’s total ad revenue, up from 15% in 2024.

Where it appears

The Shorts feed on the YouTube mobile app. Ads appear as full-screen vertical videos interleaved between organic Shorts. Users can tap to dismiss after roughly 3 seconds, similar to TikTok In-Feed Ads.

Creative specs

Aspect ratio: 9:16 mandatory. Resolution: 1080×1920 minimum. Duration: up to 60 seconds; optimal performance at 15 to 30 seconds. File format: MP4 or MOV, H.264. Vertical native filming is required: a horizontal video pillarboxed into a 9:16 frame underperforms a true vertical creative by 30 to 50% on view-through rate, according to Think with Google’s vertical-video case studies.

Cost benchmarks 2026

CPM ranges from $4 to $8 in the U.S., significantly below the $8 to $15 of standard in-stream. CPV when bid that way: $0.05 to $0.15. The cost gap is the headline insight: Shorts deliver 2 to 3x more impressions per dollar than standard in-stream for advertisers willing to produce vertical creative.

Audience and conversion patterns

Shorts skews younger: 18 to 34 over-indexes heavily. View-through rate averages 12 to 18% on completed Shorts ads. Click-through rate to landing page ranges 1.5 to 3%. Conversion rate to purchase or sign-up runs roughly 30% below standard in-stream for the same advertiser, but the impression volume often compensates: more cheap views times a slightly lower conversion rate still beats fewer expensive views in many tests. Beauty, fashion, food, and gaming verticals see the strongest Shorts performance. Finance and B2B SaaS struggle on Shorts: the audience composition does not match the buying committee.

Video reach campaigns: bumper plus skippable plus in-feed under one budget

Video reach is a campaign type, not a format. Google launched it in 2022 as a way to optimize toward unique-reach goals across multiple formats simultaneously. The advertiser uploads bumper creative, skippable in-stream creative, and optionally in-feed creative. Google decides the mix in real time based on which format is cheapest at delivering the next incremental reached user.

Why it exists

Buying bumper, skippable, and in-feed as separate campaigns leads to overlap: the same viewer is reached three times when one would suffice for a reach goal. Video reach campaigns deduplicate at the auction layer. The advertiser sets a target reach number; Google optimizes the format mix to hit it at the lowest CPM.

Cost benchmarks 2026

Effective CPM for video reach campaigns runs 20 to 35% below the equivalent CPM of buying bumper standalone, according to WordStream’s reach campaign benchmarks. The savings come from format substitution: when bumper inventory is bid up, Google shifts spend to in-feed; when in-feed thumbnails are exhausted, it shifts to skippable.

When to use it

Reach-led campaigns at scale. Brand launches, product launches, awareness pushes ahead of seasonal moments. Not appropriate for direct-response goals: video reach optimizes against unique-reached users, not against conversions.

VideoView campaigns: the new view-optimized objective

VideoView campaigns launched in 2023 as a successor to view-optimized TrueView. The campaign optimizes against the broadest definition of a “view”: any combination of skippable in-stream views, in-feed views, and Shorts views that maximizes the count of viewable video sessions for the budget.

How it bills

Effective CPV. The advertiser sets a target CPV (or lets Google optimize). Google delivers across skippable in-stream, in-feed, and Shorts inventory in whatever mix produces the most views per dollar.

Cost benchmarks 2026

Effective CPV for VideoView typically lands 15 to 25% below standalone skippable in-stream campaigns at the same target CPV setting. The arbitrage comes from Shorts inclusion: Shorts views are cheaper than in-stream views, and VideoView happily substitutes them when they are available.

When to use it

View volume goals (top of funnel, brand consideration), not click goals. The campaign type does not optimize against website conversions: it optimizes against view count.

YouTube TV and Connected TV ads: the living-room shift

Connected TV (CTV) viewing on YouTube has exploded since 2022. Think with Google’s 2025 CTV measurement data shows YouTube as the most-watched ad-supported streaming service in the U.S. by total watch time, ahead of Hulu and Peacock. CTV ads now run on YouTube via the YouTube TV app on Roku, Fire TV, Apple TV, Chromecast, and smart-TV native apps (Samsung, LG, Sony).

Where it appears

Pre-roll, mid-roll, and post-roll on YouTube TV (the linear-TV-style streaming product), and inside the YouTube app on smart TVs and streaming sticks. CTV inventory is sold inside standard video campaigns when the advertiser opts into the “TV screens” device targeting.

Creative specs

Resolution: 1920×1080 minimum, 3840×2160 (4K) preferred. Aspect ratio: 16:9 mandatory (9:16 does not display on TV screens). Duration: 6 to 30 seconds, with 15 and 30 the standard. Audio: critical. CTV viewers watch with sound on, unlike mobile. Captions help, but the creative must work with audio as the primary channel. File format: MP4 H.264 or H.265.

Cost benchmarks 2026

CPM ranges from $20 to $45 for U.S. CTV inventory. The premium over mobile reflects the engaged audience: CTV viewers watch 40 to 55% of ads versus 25 to 35% for mobile in-stream, according to Tinuiti CTV measurement. The ads are non-skippable on most CTV surfaces (Roku, Fire TV, smart TV native apps), with skippable available only inside the YouTube native CTV app.

CTV is no longer a niche channel. Search Engine Land’s 2026 CTV outlook projects CTV ad spend in the U.S. to cross $35 billion this year, with YouTube capturing roughly 40% of the ad-supported streaming market. The format is the natural home for 30-second brand creative that mobile cannot accommodate.

Demand Gen: the YouTube + Discover + Gmail consolidation

Demand Gen is the campaign type that replaced both Discovery campaigns and standalone in-feed YouTube ads in 2024. A single Demand Gen campaign serves the same creative set across YouTube (in-stream, in-feed, Shorts), Discover feeds (the personalized feed in the Google app and on Android home screens), and Gmail Promotions and Social tabs.

What changed in 2024

Before Demand Gen, an advertiser running visual ads across YouTube + Discover + Gmail had to build three campaigns with three creative sets. Demand Gen unified the buying surface. Upload up to 5 video assets in landscape, portrait, and square; up to 5 image assets in three aspect ratios; up to 5 headlines and 5 descriptions. Google’s machine learning composes the right asset mix for the surface in real time.

How it bills

CPM by default, with optional Target CPA and Target ROAS bid strategies for advertisers tracking conversions. Conversion-optimized Demand Gen runs effectively as a video-led acquisition campaign, not a brand campaign.

Cost benchmarks 2026

CPM ranges from $4 to $12 across the consolidated surface, with the YouTube share usually in the higher half of that range and the Discover and Gmail shares in the lower half. CPA targets typical of mid-market advertisers: $25 to $80 for e-commerce, $80 to $250 for B2B SaaS lead gen.

Why it matters in 2026

Demand Gen is now the default Google Ads recommendation for any advertiser running visual creative against a conversion goal who is not on Performance Max. Search Engine Land’s 2026 channel comparison places Demand Gen alongside Performance Max as the two campaign types Google is most aggressively pushing toward the broad mid-market. The unification reduces creative production cost (one set of assets, not three) at the price of placement transparency (the advertiser sees aggregate performance, not per-surface performance).

The 90-day testing playbook for new YouTube advertisers

Three months is the right unit for evaluating YouTube ads as a channel. Less than 90 days does not give Google’s machine learning enough conversion volume to optimize. More than 90 days without a structured plan turns into spend without learning.

Days 1 to 14: foundation and conversion tracking

Set conversion tracking before spending a dollar on creative. Verify that purchase, lead, and key engagement events fire correctly through the Google tag, with cross-device tracking enabled and enhanced conversions configured if available. Confirm GA4 and Google Ads conversion events are deduplicated. Without clean tracking, every benchmark in this guide is a fiction for your account.

Build the first creative slate: one 30-second skippable in-stream landscape, one 15-second bumper landscape, one 9:16 vertical Shorts cut, one 9:16 in-feed thumbnail. Four assets minimum, eight preferred. Make sure each works without sound for the first 3 seconds.

Set up two campaigns: one Demand Gen with conversion goal, one standalone skippable in-stream with target CPV. Budget allocation: 60% Demand Gen, 40% skippable in-stream during the test phase.

Days 15 to 30: learning phase

Hold creative and targeting steady. Resist the urge to adjust bids daily. Google’s auction algorithms need 7 to 14 days of stable signal to learn which combinations convert. Mid-test creative swaps reset the learning clock.

Watch view-through rate, click-through rate, and cost per acquisition by creative variant. Identify the top two performers by CPA. Document them in writing: which hook, which CTA, which audience.

Days 31 to 60: kill, double, expand

Pause the bottom 50% of creative variants by CPA. Double the budget on the top two. Add one new format to the test mix: if Demand Gen and skippable in-stream are working, add bumper through a video reach campaign. If only Demand Gen is working, add a video reach campaign with the same creative slate.

Test a second audience layer: existing-customer remarketing alongside the cold prospecting that ran in days 1 to 30. Remarketing CPV typically runs 40 to 60% lower than cold; the conversion rate runs 3 to 5x higher.

Begin testing CTV inclusion if budget supports it. Add a CTV-only campaign with 15-second creative. Expect higher CPM and longer attribution windows. Measure post-view conversion lift, not last-click.

Days 61 to 90: scale the winners

The campaigns that have produced the lowest CPA over a rolling 14-day window are the scale candidates. Increase budget by 20 to 30% per week, not more. Aggressive jumps trigger learning resets and degrade CPA temporarily.

Add geographic expansion if the home market has saturated. Expand creative production to cover the next vertical formats: square 1:1 if not already produced, vertical Shorts variants of all winning hooks.

Document the playbook in writing for the next quarter: which formats worked, which CPAs were sustainable, which creative hooks survived the cull. The next 90 days run on this foundation.

Common mistakes that drain budget on YouTube

Treating YouTube as one channel

It is not. Skippable in-stream, Shorts, and CTV are three different audiences with three different creative requirements and three different conversion patterns. An advertiser running a single landscape 30-second creative across all three is leaving 30 to 50% of potential performance on the table. Build vertical Shorts cuts. Build CTV-specific 15s with sound design. Build a 6-second bumper from the same idea.

Skipping the first 5 seconds

Skippable in-stream lives or dies on seconds 0 to 5. Most advertisers waste those seconds on logo bumpers and brand intros. The viewer skips at second 5. The advertiser pays nothing, and reaches no one. The opening must contain the hook, the product, and the visual reason to keep watching.

Running ads without cross-device conversion tracking

YouTube viewers split across mobile, desktop, and CTV. A user who sees a YouTube ad on mobile and converts on desktop is invisible to last-click tracking. Think with Google’s cross-device measurement studies show 30 to 50% of YouTube-attributed conversions happen on a different device than the impression. Without cross-device tracking, the channel looks unprofitable when it is in fact carrying the awareness load.

Over-targeting the audience

Stacking five interest layers, three demographic layers, and a custom-intent keyword list onto the same campaign starves it of volume. The auction needs scale to optimize. Start with one audience layer, run for 14 days, then narrow only if CPA is unacceptable. The instinct to “target precisely” is exactly the wrong instinct for machine-learning-led platforms.

Confusing CPV with CPA

A $0.05 CPV is meaningless if the conversion rate is 0.1%: that produces a $50 CPA. A $0.20 CPV with a 2% conversion rate produces a $10 CPA. Always evaluate at the CPA layer. The CPV number is an intermediate metric, not a goal.

Buying masthead without a downstream plan

The masthead reaches tens of millions of viewers in a single day. If the only follow-up is an organic landing page, most of that reach evaporates. Masthead works when it is paired with a remarketing campaign that retargets the masthead-exposed audience for the following 14 to 30 days with skippable in-stream and Demand Gen. Without the follow-through, the masthead is a vanity metric.

Ignoring placement reports

Google video partners (the network of non-YouTube sites and apps) is on by default in many campaign types. Performance on this network is consistently weaker than YouTube proper. Pull the placement report monthly. Exclude underperformers. The exclusion list is one of the highest-leverage optimizations on the platform.

Conclusion: format selection is strategy, not tactics

The 2026 YouTube ads stack rewards advertisers who think structurally. The format choice is the strategy. Skippable in-stream is the workhorse for direct response. Bumper anchors reach plans. Shorts compounds cheap impressions on younger audiences. In-feed harvests high-intent users. CTV captures the living-room shift. Masthead delivers the day-one moment for major launches. Demand Gen consolidates the whole funnel for advertisers willing to trade placement transparency for creative efficiency.

The advertisers who win on YouTube in 2026 are not the ones with the biggest budgets. They are the ones with the most disciplined creative pipeline (vertical, square, and landscape variants of every concept), the cleanest cross-device conversion tracking, and the patience to let the 90-day playbook play out before declaring the channel a winner or a loser.

Start with the playbook. Run it without flinching. Document what worked. Scale what survived. The format ecosystem is large, but the discipline is small: clean tracking, real creative variation, patience through the learning phase, ruthless culling at day 30. Everything else is noise.
