Note: The All Inventory dashboard can be used to view all available inventory to inform purchasing decisions when creating a Marketplace Package. For more information on the All Inventory dashboard, see View all available inventory.

To optimize deal performance and efficiency, for example, bid rates with DSPs, it is recommended that you use some of the targeting options available to you when you create Marketplace Packages.

For all Marketplace Packages, it is best practice to include the following targeting options:

  • Publishers or Deals with Publishers, domains, app-bundles, or segments: You must target at least one publisher, Deals with Publishers, domain/app bundle, or segment. We recommend that you apply segment targeting, then domain and app bundle targeting, and only apply publisher targeting if you need to target certain publisher integrations or Deals with Publishers. If you have app bundle, domain, or segment targeting applied, there is generally no need to apply publisher targeting.

    • Segments: Always apply segment targeting when you can. You can choose to only target segments, or you can combine segment targeting with domain and app bundle targeting. For more information about segment logic, see How segment targeting works.

    • Domain and App Bundles: Always apply domain and app bundle targeting if you have a list of specific domains and app-bundles to target. For more information about how to structure domain targeting, see How domain targeting works.

    • Publishers or Deals with Publishers: If you do not have a list of specific domains and app-bundles or segments to target, you must target at least one publisher. It is recommended that you select the option to target all publishers, rather than selecting individual publishers.

      Note: New publishers that onboard with Index are not automatically included in targeting. To make sure that you are targeting all available inventory, it is a best practice to occasionally deselect and then reselect the Select All checkbox to reset your targeting to include the most recent list of available publishers.

  • Countries: Limit targeting to the countries with the IP traffic that the buyer intends to buy from.

  • Formats and Sizes: Target a specific format, either banner, native, or video. If you have a deal that targets multiple formats, consider creating separate deals for each format to increase deal performance.

  • Inventory Channel: Target either Web or In-App to keep bid requests more relevant.

Further optimization tips for STV-specific Marketplace Packages

Note: The Streaming TV dashboard can be used to view available STV inventory to inform purchasing decisions when creating a Marketplace Package. For more information on the Streaming TV dashboard, see View available streaming TV inventory (Alpha).

Index highly recommends the following targeting tips for any STV (Streaming TV) deal:

For all STV deals:

  • Publishers: Target STV publishers only. Contact your Index Representative to get a list of STV publishers.

  • Formats and sizes: Target Video (all sizes) only.

For large screens only:

  • Device types: Target the following device types only:

    • Connected TV (CTV)

    • Connected device (CTV)

    • Set-top box (CTV)

  • Inventory channels: Target In-App only. This will filter out any web traffic.

For all screen sizes, no device or inventory channels targeting is needed.

If the buyer has additional targeting requirements, these should be applied as well, but any optional targeting might impact deal scaling. This additional targeting could include the following: 

  • For ads over 30 seconds, it is recommended that you target Ad duration: For example, if your video ad has a length of 30 seconds, choose 30 seconds or longer.

  • Content ratings: If you want to target content ratings, contact your Index Representative to validate whether your targeted publishers signal content ratings. If there are ratings that you want to target that are not on the list, contact your Index Representative.

  • Content livestream: If you want to target live content, contact your Index Representative to validate whether your targeted publishers support live content.

  • Content genres: If you want to target specific content genres, contact your Index Representative to validate whether your targeted publishers signal content genre. If there are genres that you want to target that are not on the list, contact your Index Representative.

  • Content languages: If you want to target specific content languages, contact your Index Representative to validate whether your targeted publishers signal content languages.
