Creative Assets

Learn how to create and upload engaging creative assets for your advertising campaigns.

Before you begin, make sure to review our Advertiser & Creative Content Guidelines.

Creative Types Supported by Chartboost 🔗

• Animated GIF - These engaging ads are more lightweight than video ads and can seriously increase your eCPM.
• Static Interstitial - Full-screen static ads are the simplest and least intrusive way to grab your players’ attention.
• Playable Ads - The best way to engage with your gamers is with playable ads. Playable ads must be made in MRAID Playable format.
• Video with a static end card - High-quality video ads captivate players with end cards that feel like personal recommendations. Reward your players with in-game goodies or virtual currency after they watch a video.
• Video with a playable/interactive end card - Playable, or interactive, end cards play after a video ad and allow gamers to interact with them. These ads are very flexible, empowering you to have more creativity and compatibility with different devices! Playable/Interactive End Cards must be made in MRAID Playable format.
