The ‘Allow for Cookieless Users’ feature ensures that impressions are served to users who may have cookies disabled or in cases where no cookie is shared by the publisher. This allows campaigns to continue running even in environments where cookies are unavailable for targeting. This feature is automatically applied to all CTV, OTT, and In-App Line Items, as requiring cookies in these environments may prevent the campaign from serving.

It is also recommended to enable this feature for streaming Audio campaigns since cookies are often not available for targeting in these environments. For Mobile Web campaigns, enabling the ‘Allow for Cookieless Users’ feature is essential to serve impressions to Safari users, as Safari blocks third-party cookies by default.

Please note that while this feature ensures broader targeting, including users without cookies may impact the accuracy of frequency caps and conversion tracking when cookies are unavailable.
