Serve users with Limited Ads

AI-generated Key Takeaways

• As of January 14, 2021, the IMA HTML5 SDK can serve limited ads even when users don't consent to cookies or in GDPR/ePrivacy regions without a valid TC string.

• Publishers using Google Publisher Tag (GPT) need to configure PrivacySettingsConfig.limitedAds to disable GPT-related cookies for limited ads functionality.

• When using limited ads, ensure the player is configured to request the stream manifest with withCredentials=false due to potential cookies from dai.google.com.

• Limited ads can be automatically enabled through integration with a Consent Management Platform (CMP) using the latest HTML5 SDK version.

Select platform: HTML5 Android iOS

As of January 14th 2021, the IMA HTML5 SDK allows limited ads to be served when the user does not give consent to cookies, the user denies consent to cookies, or when IMA does not receive a valid TC string in GDPR and ePrivacy regions following the grace period of IAB TCFv2 integration.

For DAI SDKs you must set the ltd parameter using StreamRequest.adTagParameters . Please see this Limited ads guide for more information.

Publishers using Google Publisher Tag (GPT) will need to also set PrivacySettingsConfig.limitedAds to disable GPT-related cookies. The following code snippet shows how to do this based on IMA's companion ads guide:

...

<!-- Register your companion slots -->
<script type='text/javascript'>
  googletag.cmd.push(function() {
    googletag.pubads().setPrivacySettings({
      limitedAds: true,
    });
    // Supply YOUR_NETWORK and YOUR_UNIT_PATH.
    googletag.defineSlot('/YOUR_NETWORK/YOUR_UNIT_PATH', [728, 90], 'companionDiv')
      .addService(googletag.companionAds())
      .addService(googletag.pubads());
    googletag.companionAds().setRefreshUnfilledSlots(true);
    googletag.pubads().enableVideoAds();
    googletag.enableServices();
  });
</script>

...

Publishers are still responsible for playback of the stream manifest. The manifest URL continues to point to dai.google.com which is a cookied domain and may carry cookies. Because of this, the player needs to be configured to correctly request the manifest withCredentials=false.

Please see the following links to set this for your specific player:

• hls.js
• JW Player (scroll for withCredentials property)
• Shaka Player

It is also possible to enable limited ads automatically through integrating with a Consent Management Platform (CMP). This is supported on the latest version of the HTML5 SDK as of January 14th 2021.
