It is available for

• Images

• Videos

• 3rd party tags

• Depending on your organization settings and your campaign type, your creatives will be subject to an auditing process.

  • Creatives that we host (like banners, videos, or native ads) and External URLs are subject to manual review.

  • Third-party tags are audited using our ad quality partners: Geoedge & TMT. Check Ad scans fees for more information.
    

• Creative status is available to be checked on the Creatives section table.

• If an SSP rejects your creative, please check the “Why are my creatives not being approved?” article.

• Use the Creatives section (left menu), the campaign launcher, or the Creative area within campaigns or strategies to upload, edit, and manage assets.

• Always check the technical specifications for the creative type you want to use before uploading it or even designing it.

• Click URL and Tracking

  • We recommend you set the click URL, impression pixel, and HTML pixel at the creative level.

  • If you want to track events, use conversion numbers 2 to 5 for campaigns measuring drive-to-store or app marketing.

  • For HTML/MRAID video, ensure video event tracking macros are implemented if used; otherwise, prefer VAST.

  • Check our Macro glossary to add information to your 3rd party tags.
    

• Hosting guidance:

  • For video (especially CTV/DOOH), host on mediasmart servers when possible.

  • Prefer VAST URL over XML to enable macro passing.

• Best practices:

  • Provide multiple image sizes to access a broader inventory, and A/B test.

  • Keep file weights within limits. The lighter, the better.

  • Verify language, attributes (e.g., expandable, autoplay audio), labels, and companion ads, before launching the ad.

• TV or CTV ads are typically 1920x1080 HD video ads, but there is also a small amount of vertical video.
  

• For video, host on mediasmart servers when possible.
  

• We have a feature automatically adapts a video sizes - respecting the aspect ratio - to match the requirements of different placements. It is activated by default. Learn more about the feature and about about aspect ratios.
  

• For app growth campaigns, assets should include for better discovery & attribution

  • QR codes to download the app (for CTV app sync)

  • App branding (logos, colors, etc.)
