What is a pre-roll video ad?
A pre-roll ad is a video ad that plays before the content a user has already chosen to watch. It runs inside the video player, on mobile and desktop and is either skippable after a few seconds or non-skippable. Advertisers buy it on a CPM basis and it is the video format most performance offers start with.
Video is the format everyone wants a piece of right now, but it is not a format that flatters every offer equally. A 15-second spot that sells a slot bonus in three seconds is doing something a banner never could. A 15-second spot explaining a B2B software trial is mostly burning budget.
The question advertisers ask first is always the same one: does my vertical work with this? This guide answers it. We go through the verticals that consistently perform on video inventory, why they work, which pre-roll configuration to pick and what the creative needs to do in the first three seconds.
TL;DR
- Video suits offers with something to show, a fast decision and a low-friction conversion step.
- The strongest verticals on video inventory: iGaming and betting, sweepstakes, mobile apps and gaming, dating, nutra, finance and crypto, mVAS, e-commerce and software or VPN offers.
- Non-skippable fits bonus-led and prize-led messaging. Skippable fits offers that need explaining or that you are retargeting.
- 15 seconds usually beats 30, and 30 seconds is the cap on most video inventory.
- Weak fit: long B2B sales cycles, very low-payout email submits and any offer with nothing visual to demonstrate.
Why Should Video Be in Your 2026 Media Plan?

The money has already moved. According to the 2026 IAB Digital Video Ad Spend and Strategy Report, U.S. digital video ad spending is projected to surpass $80 billion this year, growing 11 percent year over year and close to 20 percent faster than the total ad market.
That is the brand side of the industry. On the performance side the logic is the same but the reasoning is simpler: video buys you attention at a moment the user has already chosen to pay attention. They pressed play. The screen is in focus. In many cases the sound is on.
Wyzowl’s 2026 State of Video Marketing survey puts a number on the preference: 63 percent of consumers say a short video is how they would most like to learn about a product or service, ahead of text articles, ebooks, infographics and sales calls. And 89 percent say video quality affects how much they trust a brand, which is exactly why the verticals that live or die on trust perform so differently on video than on display.
What Makes a Vertical a Good Fit for Video Ads?
Before the list, the filter. A vertical works well on pre-roll when it ticks most of these:
1. There is something to show. Gameplay, a prize, a product in someone’s hand, an interface, a face. If your entire offer is a text promise, video adds cost without adding persuasion.
2. The decision is fast. Video is strongest where the user can go from curious to converted in one session. Offers with a research phase measured in weeks lose the momentum video creates.
3. The conversion step is light. Registration, app install, one-tap subscribe, short lead form. Heavy KYC or long checkout flows leak most of the attention you just paid for.
4. The audience is mobile-first. Most video inventory is consumed on mobile, often with autoplay muted. Verticals with mobile-native funnels have a structural advantage.
5. The message survives a compliance pass. Regulated categories can absolutely run video, but the creative and the landing page need their disclosures in place or moderation slows you down.
Which Verticals Perform Best on Video Ads?

iGaming and Betting
The most natural fit on the list. Casino and betting products are visually rich by default: reels spinning, a live dealer table, an odds board updating. The offer is also a single number, the welcome bonus, which is the easiest thing in advertising to put on screen in the first two seconds.
- Format: non-skippable for bonus-led acquisition, skippable when retargeting users who already know the brand.
- Length: 6 to 15 seconds.
- Creative angle: bonus figure on screen immediately, real gameplay footage behind it, one CTA (Claim bonus, not Claim bonus and Download app).
- Watch for: age gating and responsible gambling disclosures on both the video and the landing page. GEO licensing rules vary, so build your targeting per market rather than running one global campaign. For the wider acquisition picture in this vertical, see Best iGaming Ad Networks for Affiliates.
Pre-roll also slots neatly into a multi-format sequence here: video for the first exposure, push notifications to bring the same audience back at the conversion stage.
Sweepstakes and Giveaways
Sweeps is the vertical with the shortest possible message, and video makes that message concrete. A prize you can see beats a prize you have to read about.
- Format: non-skippable.
- Length: 6 to 10 seconds.
- Creative angle: show the prize in the first frame, name the country, show the entry step. Nothing else.
- Watch for: creative fatigue arrives faster in sweeps than anywhere else. Build a rotation of three to four videos and set a frequency cap from day one rather than after performance drops.
Mobile Apps, Games and Utilities
Gameplay footage is one of the highest-intent creative formats in the industry, and pre-roll gives you a full-screen placement to run it in. The user is already in a video player on a mobile device, which is where the install is going to happen.
- Format: non-skippable for games, skippable for utility apps that need a sentence of explanation.
- Length: 15 seconds.
- Creative angle: the first five seconds are actual gameplay or actual screen recording, never a logo animation. End on the store badge.
- Watch for: match the footage to the app. Fake gameplay converts on the click and dies on retention, which shows up in your payout within days.
Dating and Social Discovery
Dating sells an experience, and an experience is difficult to compress into a banner. Video gives you faces, movement and the feeling of the product rather than a description of it.
- Format: skippable.
- Length: 10 to 15 seconds.
- Creative angle: design for muted playback. Text on screen from the first second, because a dating video with no audio and no captions communicates nothing.
- Watch for: the Mainstream and Adult traffic type toggle in Mondiad campaign targeting. Set it deliberately, because it changes both your inventory and your creative rules. If your offer sits on the adult side, Best ad formats to maximize ROI on adult offers covers what changes.
Nutra and Health
Nutra is a vertical where the format upgrade is worth real money. Video lets you demonstrate: the product in hand, the routine, a testimonial delivery that reads as a person rather than a claim block. That trust gap is precisely what the 89 percent trust figure above measures.
- Format: skippable.
- Length: 15 seconds.
- Creative angle: one benefit, one demonstration, one CTA. Presenter-style delivery outperforms stock footage montages.
- Watch for: health claims need to be defensible and the landing page must match the promoted product, which is a Mondiad creative guideline, not just good practice. Build the disclaimers in before moderation, not after.
Finance, Crypto and Trading
Higher payouts here absorb a CPM premium comfortably, and the products genuinely need explaining. A trading platform, a card, a savings product: none of those fit in a banner headline.
- Format: skippable, so you pay for the users who chose to keep watching.
- Length: 15 to 30 seconds. This is one of the few verticals where the longer end earns its keep.
- Creative angle: show the interface. Credibility signals (regulation, security, real numbers) do more work than urgency in this vertical.
- Watch for: finance is a regulated category in Mondiad moderation. Disclosures on video and landing page keep approval within the usual few hours instead of a back and forth. Our finance push ads case study shows how the same audience converts one step further down the funnel.
mVAS and Mobile Content
Carrier billing flows are built for exactly the user pre-roll delivers: on mobile, on a phone connected to the operator you are targeting, one tap away from a subscription. Very little friction between impression and conversion.
- Format: non-skippable.
- Length: 6 to 10 seconds.
- Creative angle: state the content and the carrier flow plainly. Clarity beats cleverness where billing is involved.
- Watch for: carrier targeting matters more than GEO targeting here. See our full guide, How to advertise mVAS offers: traffic, targeting and conversion flows.
E-commerce and Direct-to-Consumer
A physical product in use is the oldest and still the best video ad. Scale, texture, how it actually works: all things a static image approximates and video simply shows.
- Format: skippable.
- Length: 15 seconds.
- Creative angle: product in use within three seconds, price or discount on screen, one CTA. Seasonal peaks reward having creatives ready in advance rather than built during the peak.
- Watch for: shipping GEOs. Nothing wastes video budget faster than serving a market you cannot deliver to. For the seasonal playbook, see our e-commerce advertising guide.

Can You Use AI-Generated Video Creatives?
Video used to be the format you skipped because production was slow. That changed. Generating three variations of a 15-second spot is now a same-day job, which matters most in the verticals where creative fatigue is fastest.
Works well: presenter-style delivery for nutra, product shots and motion graphics for e-commerce, localized voiceovers and subtitles when you run the same offer across several GEOs, fast variant testing in sweeps where you burn three to four creatives a week.
Fails predictably: synthetic gameplay for app offers, the same problem as fake footage, it converts on the click and dies on retention. AI faces delivering testimonials in nutra without a disclaimer. Anything that imitates a real person or a real brand.
Practical setup: keep one human-verified hook in the first three seconds and let AI generate the variations behind it. Test two or three variants per angle, not ten.
What Are the Compliance Rules for Video Creatives?
- The landing page must match the promoted product. This is a Mondiad creative guideline, not a suggestion.
- Regulated categories need their disclosures on the video itself, not only on the landing page: age gating and responsible gambling for iGaming, defensible claims for nutra, risk and regulation notices for finance.
- No fake interface elements. Simulated system alerts, fake play buttons and fake close buttons fail moderation.
- Set the Mainstream or Adult traffic type deliberately. It changes both your inventory and the creative rules that apply to you.
- If you use AI-generated video, check your own transparency obligations per market before you scale.
When Are Video Ads Not the Right Call?
Being honest about this saves budget:
- Long-cycle B2B. If the buying committee meets twice before a decision, video top-of-funnel can build awareness but should not be judged on direct conversions.
- Very low-payout email submits. When the payout is small, the CPM premium video commands needs volume and a tight funnel to make sense. Test it, but test it with a cap.
- Offers with nothing to show. If the storyboard is a logo, a headline and a button, you have made a banner with a play button in front of it. Run the banner instead, and check the banner ad sizes reference before you build it.
- Markets where your funnel is not mobile-ready. Video traffic is heavily mobile. If the landing page is slow or the form is desktop-shaped, the drop-off happens after you have paid for the attention.
What Do You Need Before You Launch a Video Campaign?
Video campaigns follow the same flow as the formats you already run: campaign details, targeting, bid, then delivery controls. The difference is the creative, an MP4 instead of an image. Pre-roll is currently in beta, so access is granted on request rather than from the standard Create Campaign list.
Creative specs: mp4, avi or mov, bit rate 8 MBit/s, up to 20 MB, minimum resolution 240p, maximum length 30 seconds.

Frequently Asked Questions
Which vertical performs best with video ads?
There is no single winner. The verticals with the most consistent video activity are iGaming, sweepstakes, mobile apps and gaming, dating and nutra, because all of them combine a visual product with a fast decision. Your own result depends on GEO, payout and creative quality, so ask your account manager for benchmarks in your vertical before you set targets. Our breakdown of which ads work best for affiliate marketing covers how formats and verticals pair up more generally.
Can I run video ads for adult offers?
Yes. Traffic type is a targeting setting in the campaign builder, with Mainstream and Adult as separate toggles. Set it deliberately, since it determines both your inventory and the creative rules that apply. The Power of Paid Ads in Adult Content goes deeper on this side of the network.
Do I need a separate landing page for video traffic?
Not necessarily, but the landing page must match the promoted product, and it needs to load fast on mobile. Video traffic skews mobile heavily, so a desktop-shaped funnel will cost you conversions you already paid for.
How much budget should a first video test have?
Accounts fund from $50. Start with one GEO, one offer and two or three creative variations rather than spreading a small test across many markets.
Can I combine video with other formats?
Yes, and it is the approach we recommend. A common pattern is pre-roll for first exposure, then push or in-page push to re-engage the same audience at the conversion stage. All eight formats run from the same account and the same balance.
