Ad formats

What your ad actually looks like.

Banner, video, native, popunder. Each one shows up differently, costs differently, and converts differently. Picking the wrong format is the most common reason campaigns underperform — and the easiest thing to fix.

12 min read · Updated May 2026

Most marketers reach for the same ad format for every campaign. They picked it once, it worked, and they kept going.

The opportunity is in the match. The right format for a brand-awareness push is different from the right format for a retargeting campaign. The format that drives demos for SaaS is different from the one that fills tables for a local restaurant. The difference between a campaign that converts well and one that converts exceptionally is often just the format.

The framework that follows walks you through the four formats programmatic uses — what they look like, what they cost, and what each one is best at. By the end, you'll know which one fits your campaign before you spend a dollar.
01
Display / Banner

Banner ads.

The image-based ad you've seen on every website. Rectangle, square, skyscraper, leaderboard — all banners. Familiar, fast-loading, and remarkably effective when matched to the right goal.

Banner ads load instantly, work on every device, and run at the most accessible CPMs in programmatic. They're the dependable workhorse — flexible, scalable, and easy to refresh.

Where they shine: Retargeting (someone visited your site, now they see your banner across the web), brand awareness (efficient impressions compound over time), and product reminders (cart abandonment, pricing pages).

Best paired with intent: Banners reward audiences who already know you. They're reminders, not introductions. Pairing banner with retargeting is one of the highest-ROI combinations in programmatic — and the easiest place to start.

Video

Video ads.

The pre-roll, mid-roll, or in-stream ad you see on YouTube and across the web. Also outstream — videos that play in the middle of articles. Premium attention, higher engagement, and impossible to scroll past.

Video is the format that commands attention. People stay with it longer, remember it more, and act on it more often. The premium CPM reflects premium engagement — and when you need a memorable impression, nothing else gets close.

Where it shines: Brand storytelling, demo-heavy products, anything emotional or visually demonstrable. If your product is best understood when shown rather than described, video pays for itself.

Best paired with intent: Video is your premium impression — give it premium creative. A well-produced 15- to 30-second spot will outperform a longer, lower-quality piece every time. Reserve video for moments where attention matters most.

Native

Native ads.

The ad that lives inside the content experience. It sits in the article feed, the social timeline, the recommended-content section. Higher trust, dramatically higher engagement, and naturally suited to mobile.

Native feels like editorial content. It's labeled "sponsored" or "promoted" (transparency is required), but it lives in the same visual format as the surrounding content — a headline, an image, maybe a short paragraph. People engage with native at 3–5× the rate of banner, especially on mobile.

Where it shines: Content marketing (driving traffic to a blog post or guide), thought leadership, anything where you want curiosity over urgency. On mobile, native is the highest-engagement format available.

Best paired with intent: Native rewards content. Pair it with a destination that delivers on the headline's promise — a guide, a useful article, a free tool. The audience clicks expecting content, and when they get it, they remember you.

Popunder

Popunder ads.

A new browser window opens behind the one you're using, and you see it when you close the main tab. The most cost-efficient path to mass reach in programmatic — and uniquely powerful for the right campaigns.

Popunders deliver something no other format can: a full-page, full-attention impression at the lowest CPMs in programmatic. Used thoughtfully, with the right offer and the right audience, they drive measurable brand recall and reach figures that other formats can't match for the spend.

Where it shines: Mass-reach awareness for consumer products at the most efficient CPMs in programmatic. Brand recall studies show popunders outperform on memorability because the user gets a full-page ad — every dollar buys real attention. Especially strong for entertainment, gaming, lifestyle, and large-audience consumer offers.

Best paired with intent: Popunder is your reach play. Match it to a campaign where every impression counts and a clear, simple offer that lands instantly. When you need scale on a small budget, this format does what no other can.

The decision framework

Match the format to the moment.

Four questions, four answers. Walk through them in order — the first match points you to the format that fits your campaign.

Are you retargeting people who already visited your site?
Banner is the natural fit. Retargeting works because the audience already knows you, and you need efficient, frequent reminders — exactly what banner delivers. At $2–8 CPM, you maximize the touchpoints from your warm audience pool.
→ Use banner
Is your product visual, emotional, or best shown in motion?
Software demos, beautiful products, services that come alive when shown — video earns its premium here. Allocate at least $1,000 for a meaningful test, and lead with your strongest creative for the biggest impact.
→ Use video
Are you driving traffic to a piece of content?
Native is the format that matches the destination. Guides, blog posts, case studies, free tools — when the headline and the page deliver content, native delivers some of the highest engagement rates in programmatic. Trust stays high and the experience stays consistent.
→ Use native
Do you need maximum reach for a consumer product on a focused budget?
Popunder is your reach multiplier. For consumer brands in entertainment, lifestyle, or mass-market categories, popunder delivers up to 10× the impressions of banner for the same spend — making it the most cost-efficient path to scale when reach is the goal.
