Ad Format Specs

Based on standard IAB guidelines and programmatic best practices:

• Display (Banners): File types: JPG, PNG, GIF (static or animated); max file size: 700KB; recommended sizes: 300x250 (medium rectangle), 728x90 (leaderboard), 320x100 (large mobile banner), 300x600 (half page), 160x600 (wide skyscraper), 970x90 (large leaderboard), 320x50 (mobile banner), 468x60 (full banner); aspect ratios: various, but ensure responsive; animation length: max 30 seconds, 3 loops.
• Native: File types: JPG or PNG for image; max image size: 700KB; recommended image dimensions: 1200x628 (landscape, 1.91:1 aspect ratio) or 600x600 (square, min 600x314); headline: max 60 characters; description: max 150 characters; optional logo: 128x128; ensure image is high-resolution (at least 72 dpi) and not cropped more than 20% symmetrically.
• Video: File types: MP4, MOV, AVI (with H.264 compression preferred); max file size: 700KB (compress for short clips); recommended duration: 15-30 seconds; aspect ratios: 16:9 (horizontal) or 9:16 (vertical for mobile); frame rate: 30 fps; audio: stereo AAC or MP3 at 128kbps+; progressive scan, fixed frame rate; no auto-play on all publishers.
• In-App: File types: JPG, PNG for banners; same as native for integrated; max size: 700KB; banner sizes: 320x50 (mobile banner), 320x100 (large mobile banner), 320x480 (interstitial); native: headline max 60 chars, description 150 chars, image 1200x628 or square; optimized for mobile screens, ensure touch-friendly.

Best Practices: Match assets to format/objective (e.g., video for storytelling, native for engagement); compress files with TinyPNG or Handbrake to stay under 700KB; include strong CTAs (e.g., “Learn More”); test on multiple devices; use high-resolution images (72 dpi+); keep banner animations simple (max 3 loops); add subtitles to videos; consult creative support for compliance.

Troubleshooting: Upload error? Verify file type (JPG/PNG for images, MP4 for video) and size (<700KB). Asset not previewing? Clear cache or switch browsers. Disapproved? Check specs (e.g., dimensions) and resubmit. Animation issues? Ensure GIF loops correctly. Cropped native image? Use 1200x628 or 600x600 dimensions.
