Bulk upload of creatives
It is available for
Creative approval and quality
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.
DOOH approvals happen at Media Owner level and are most exhaustive. This process usually takes 24-48 hours but can take up to a week. Learn more using this guide.
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.
Considerations
Use the Creatives section (left menu), the campaign launcher or the Creative section 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 creative level.
If you want to track events, use conversion number 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 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.
CTV creatives
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 CTV app sync, assets should include for better discovery & attribution
QR codes to download the app (for CTV app sync)
App branding (logos, colors, etc.)

DOOH creatives
For video, only available for videos hosted on mediasmart servers when possible.
DOOH approvals happen at Media Owner level and are most exhaustive. This process usually takes 24-48 hours but can take up to a week. Learn more using this guide.
Best practices:
Match screen aspect/resolution per media owner
Keep motion readable at viewing distance; avoid strobing/flashing
Use high-contrast brand elements and short copy
