General Settings

  • Name: Enter a name for the creative.
  • Advertiser: Enter the advertiser's name or select an advertiser from the drop-down list.
  • Language: Enter a language or select one from the drop-down list. Available languages are Chinese, Danish, English, Finnish, French, Norwegian, Spanish, and Swedish. At the flight level, you can apply further restrictions to only deliver the impressions of the creative to browsers that have the same language in their setting. If Any is selected for language, this will have no effect.
  • Format: Select the size based on the asset being uploaded. The uploaded asset must comply with the specified dimension.

Some considerations to take into account:

  • Samsung DSP will NOT resize Image and HTML5 assets.
  • There is no Format field for Video creatives.
  • Track Viewability: Only select if tracking viewability is desired in the platform. Checking this option for your creative will incur an additional cost. For Video creative, a VPAID component will be added and will limit available in-app inventory (CTV, Mobile in-app, etc) to prevent compatibility issues.
  • External Label: This is a free-form section and can be left blank.
    • An external label can be provided to facilitate reporting across different systems. After impressions have been delivered, reports pivoted around this field can be pulled from the Delivery extract reports.

  • Icon Position: If the above box is checked, this drop-down list enables the overlay of the AdChoices icon at either the Top right, Top left, Bottom right, or Bottom left corner of the creative asset. The default and most frequently used position is Top right.

AdChoice icon cannot be added to CTV campaigns.

Samsung Ads is proud to be a member of the Digital Advertising Alliance and its AdChoices program, which allows consumers to easily and centrally opt out of ads based on their interests. By enabling AdChoices in your creative, Samsung DSP will automatically attach the official AdChoices icon to your creative in the location of your choice and link to opt-out choices that allow consumers to refuse interest-based ad targeting by Samsung DSP. We strongly encourage you to enable this option when ad targeting is based on user history (e.g. re-targeting or behavioral targeting).

For more information on what type of data the Samsung DSP collects, opt-out choices, and our commitment to protecting consumer privacy, please visit our privacy policy.

Creative Audits

  • Declared URL: The declared URL must be the final URL where the ad will redirect, and not an ad server click tracker URL. This field is required on all exchanges. To get the destination URL for the creative:
    • Enter the click URL or click tracker into a browser address bar.
    • The final URL that appears should contain the name of the advertiser. Use this value for the Declared URL.
  • Audit requests: Checking the box for AppNexus, DoubleClick or FreeWheel (PG Only) will submit an audit request to the respective exchange. These exchanges require an audit prior to the initial bid. If not checked, the creative will not run on these exchanges, but can still run on exchanges that don’t require an audit prior to the bid.

Most exchanges perform Creative audits automatically to verify the level of quality and compliance of the creative. If you are planning to bid with this ad on any publishers accessible via AppNexus or DoubleClick, you must tick AppNexus and/or DoubleClick to submit an audit request. The same applies to FreeWheel, except that it would only work for programmatic guaranteed campaigns.
You will see the result of the audit on the Creative Listing page. Winning will only be possible once the creative has passed the audit on the exchanges where it is scheduled to bid.
