Launch pre-roll video ads that play before the content your audience already chose to watch. Full-screen, sound on, and impossible to scroll past - skippable or non-skippable, your call.
Pre-roll is a video ad that plays before the video content a user has already chosen to watch — a game trailer before a stream, an ad before a video article, a spot before an in-app video feed. Because it runs inside the publisher's own player, it inherits that player's screen real estate, sound, and attention: there's no scrolling past it, and on most inventory it plays with audio on by default.
Pre-roll comes in two flavors. Skippable ads show a countdown and a "Skip Ad" control after 5 seconds, trading some guaranteed exposure for a lower CPM and the option for engaged viewers to watch the full pitch. Non-skippable ads run the complete creative — typically capped at 15 seconds — with no way to bypass it, guaranteeing full message delivery at a premium. Mondiad serves both through standard VAST 4.x and VPAID 2.0 tags, so your existing creative pipeline plugs in without changes.
MP4/AVI/MOV (up to 30s, up to 20 MB) or a hosted VAST/VPAID tag, plus brand name and click-through URL.
The moment a viewer presses play on the content, the player fires a VAST request; Mondiad's bidder returns a matching pre-roll tag in milliseconds.
Full-screen inside the player, sound-on by default. Skippable ads show a countdown; non-skippable ads run to completion.
Standard VAST quartile events (25/50/75/100%) plus click-through, all reportable via S2S postback for lead-gen attribution.
The verticals and campaign types where this format consistently outperforms alternatives.
The strongest vertical for pre-roll. Gameplay-footage creatives before other video content drive install volume that static formats can't match.
Utility, finance, and social apps use 15-30s demo creatives to show the product in motion before the install click.
Trailers and platform promos placed directly ahead of the content type they're trying to compete with.
Product-in-use footage for brand awareness and seasonal launches, retargeted with a follow-up native or push sequence.
Trading platforms and signal services use 30s explainer cuts — more room to build a pitch than any text-based format.
Instructor-led hooks and outcome testimonials outperform static creative for lead-gen into course funnels.

The honest take on when this format wins — and when another format wins.
Native blends in and wins on post-click intent. Pre-roll interrupts on purpose and wins on recall and message delivery — better for awareness than direct response.
Video commands a full attention span with sound; banner is a glance-rate format. Pre-roll costs more per impression but delivers far more message per view.
Both command full attention, but pre-roll is bound to a user's video-watching intent while interstitial fires on app or page transitions — different moments, different psychology.
Push wins on cost-per-click speed and volume. Pre-roll wins when the pitch needs motion, sound, or a demo — install and streaming offers especially.
"Tested a 15s skippable cut against a 30s non-skippable cut on the same mobile game install offer, same GEOs, same budget. The non-skippable version drove 41% more installs despite a higher CPM — full gameplay footage mattered more than reach."
