Target line items with video metadata

Learn how to pass video metadata to the ad server by appending &cust_params= to an ad tag.

You can configure an active video advertising campaign to target videos with specific metadata. When the line item targeting matches the metadata of the video, the line item becomes eligible to serve.

Target ads to specific videos

Use the following steps to target specific videos for a campaign:

  1. Set the custom parameters for the video.
  2. Add the custom parameters to the ad tag to pass the values to your ad server
  3. Set the targeting for advertising campaign line item

Set the video custom parameters

  1. From your Media Library, click the name of a video. The details page for the video appears.


    If you have a new video, add the video to your library before completing this step.

  2. On the Basic Information tab under Custom Parameters, add your custom parameters. For example, if the ad targeting is movie=startrek, enter movie in the Key textbox. Then, enter startrek in the Value textbox.

  3. Click Save.

Add the custom parameters to the ad tag

  1. From the Ad Schedules page, click the name of the ad schedule. The ad schedule detail page appears.
  2. For the specific ad break you need to edit, click β‹― > Edit. The ad break properties appear.
  3. At the end of the ad tag, append &cust_params=, the custom parameter name, and the macro: &cust_params=name%3D__item-name__.

    For example: To add movie=startrek to the ad tag, you append &cust_params=movie%3D__item-movie__ to your ad tag.
  4. Click Done.
  5. Click Save.

Set the targeting for a line item

  1. Open your ad server and find the relevant line item.
  2. Use the JWP custom parameters to set the key-value targeting for the line item. Use the custom parameter Name for the key. Use the custom parameter Value as the value.

    For example, if the custom parameter Name is movie, use this as the targeting key. If the custom parameter Value is startrek, use this as the targeting value.

Validate the custom parameter

After adding the custom parameter to the video, the ad tag, and the line item, you should verify that the custom parameter is being passed through the ad tag from JWP to your ad server.

  1. On a page that has the video, open your browser's developer tools panel.
  2. Click on the Network tab.
  3. Start the video playback.
  4. Filter the network traffic for the ad tag. If you are using a Google ad tag, you can search for gampad.
  5. Click on the ad tag.
  6. On the Headers tab under Query String Parameters, locate cust_params. You should see your custom targeting listed.

If you do not see the custom targeting listed, review the steps above for adding the custom parameter to the ad tag. If you still have issues, submit a support case.
