Build interactive, responsive ads at scale with Campaign Builder’s easy-to-use HTML5 ad builder, perfect for agencies and in-house marketing teams.

What Are HTML5 Ads and Why Should You Be Using Them?

What Are HTML5 Ads?

HTML5 ads are interactive, high-performing ad creatives built using HTML5 technology. Unlike static image ads, HTML5 allows animations, interactive elements, and responsive designs that adapt to different devices and ad placements. This makes them ideal for engaging audiences across display, social, and programmatic campaigns.

HTML5 ads are widely used by ecommerce brands, agencies, and in-house marketing teams to deliver eye-catching campaigns at scale.

Why HTML5 Ads Are Essential for Modern Marketing

Static images and traditional ad formats often fail to capture attention in today’s crowded digital environment. HTML5 ads offer dynamic, interactive experiences that can increase engagement, click-through rates, and conversions.

  • Interactive elements like buttons, sliders, and carousels
  • Responsive design that works on desktop, mobile, and tablets
  • Animation and motion graphics to capture attention
  • Optimized file sizes for faster loading and better performance

How HTML5 Ads Work in Campaign Builder

Campaign Builder allows you to create HTML5 ads using a visual builder with drag-and-drop functionality. You can start from ready-made templates or build fully custom designs, ensuring your ads are both professional and high-performing.

Best Practices to Optimize HTML5 Ads

  • Keep animations subtle: Avoid excessive movement that can distract users or trigger ad blockers.
  • Optimize file size: Compress assets to ensure fast load times and better performance across devices.
  • Test across devices: Make sure ads render correctly on desktop, mobile, and tablets.
  • Include clear CTAs: Encourage users to click through with prominent, interactive calls-to-action.
  • Use dynamic content: Combine with product feeds or personalization for higher relevance and engagement.

Use Cases for HTML5 Ads

  • Interactive display campaigns for ecommerce brands
  • Dynamic social media ads for Meta, Google, and programmatic networks
  • Promotional banners and seasonal campaigns
  • Retargeting campaigns with personalized messaging
