Premium Rich Media HTML5 Formats
Animated, expandable, video-enabled; here is what each format is designed for.
Standard IAB sizes with full animated banner advertising built in HTML5. Fast-loading and widely supported. Animated banners deliver consistently higher rich media ads CTR than static because motion captures attention before the user has decided whether to engage.
Starts as a standard banner. Expands on interaction to reveal video, additional content, interactive elements, or full conversion flows. Expandable banner ads achieve 4x the engagement of standard display because they give users something to discover and reward curiosity with more creative canvas than any fixed banner size could offer.
Video plays within the banner unit - no redirect, no new tab, no interruption. The user watches and acts, all within the same ad placement. Combines display reach with video storytelling in one format. The highest-impact HTML5 option for brand campaigns with a story to tell.
What Is Rich Media Advertising?
Rich media HTML5 advertising refers to interactive, animated, or video-enabled display ad formats built using HTML5 technology, where ads respond to user behaviour by animating on hover, expanding on click, playing video, or triggering multi-step interactive experiences, making them closer to mini-experiences than traditional ads.
On AdsNetwork, rich media HTML5 ads are delivered across all standard IAB sizes, fully validated against publisher specifications to ensure they render correctly on every device and browser without broken creatives or wasted spend.

Read ArticleFrequently Asked Questions
Rich media HTML5 advertising is interactive, animated, or video-enabled display advertising built using HTML5 technology. Unlike static image banners, rich media ads move, expand, play video, and respond to user interaction. The category includes animated banner advertising, expandable banner ads, and video-enabled units — all delivering significantly higher engagement than static display.
File format: HTML5 ZIP package (all assets included). Max initial load: 200KB. Max total load: 2MB. All standard IAB sizes supported. Animation: no restriction.

In HTML5 ads vs static banners, animated HTML5 delivers up to 2x the rich media ads CTR of static equivalents. Expandable rich media achieves 4x the engagement rate of standard display. The performance gap is consistent, not occasional. If you are running static banners and wondering whether HTML5 is worth the investment, the answer is almost always yes.
Expandable banner ads start as standard IAB banner units and expand on user interaction, click or hover, to reveal additional content, video, interactive elements, or conversion flows. The expanded state gives advertisers significantly more creative canvas than any fixed-size banner allows, while the compact initial state fits standard placements across every publisher.
