Step 3. Preview the creative

The creative preview is available for you to review once it is fully uploaded. You have the option to choose a different file, if required.


.mov videos will only play in preview on the Safari browser.

Step 4. Define the creative content

The Name field is auto-populated with the name of your file. Enter a Click-through URL to redirect the user upon clicking.

Step 5. Select audit options

On the Creative Attributes tab, select whether you want to submit the creative for Microsoft Advertising audit, classify the creative yourself, or exempt the creative from auditing entirely.

  • Platform Audit - Submit the creative for auditing by the Microsoft Advertising audit team.

    Audit process includes:

    • checking technical and content criteria

    • offer type categorization to enable the seller protection features on the platform

    • requirements of sellers

      Microsoft Advertising audit is mandatory but you can opt out of other platform specific audits.

    • Select your audit priority.


      Business days are from 9:00pm Sunday to 11:59pm Friday ET.

      For more information about content standards for creatives running on the Microsoft Advertising platform, see Creative Standards.

  • Self-Audit - Classify the creative yourself.


    • Self-auditing may reduce access to inventory outside of the ones you manage or own, as many sellers allow only Microsoft Advertising audited creatives. For further guidance on self-classifying, see Self-Auditing Creatives.
    • You must check the I confirm compliance checkbox in order to save the creative.
  • No Audit - An unaudited creative can run only on your managed publishers. It will not be eligible to run on third-party inventory unless the seller has opted into allowing unaudited creatives to run on their inventory.

Step 6. Add companion banner creatives (optional)

You can now add companion banners to your video creatives. Search for, and select banner ads that you have previously uploaded via the normal upload process.


You can only use banner creatives that have been previously uploaded.

Step 7. Attach third-party and segment tracking pixels (optional)

Microsoft Advertising records all impressions. If you wish to use another system to track impressions in addition, you can attach third-party tracking pixels to your creative.

To attach an existing third-party pixel to this creative, select the type of pixel from the Event drop-down menu.

Enter URLs for each tracking pixel event.

You can also attach segment pixels to your creative. Search for existing segment pixels and select from the list.

Step 8. Save the creative

Once you have defined your creative and populated the associated fields as necessary, click Save. The creative will be listed under Creatives on the Creative Manager screen.
