Detailed explanation

Session-based delivery is a frequency-capping method in ad serving where a user is shown a particular ad only once within a defined time period — often a single browsing session, but sometimes a set number of hours or a full day, depending on how the campaign is configured. Once that ad has been served to the user within the window, the ad server rotates in a different creative or simply stops serving that unit to the same person until the window resets.

The purpose of session-based capping is to protect both the user experience and the advertiser's budget: showing the same ad to the same visitor dozens of times in one sitting wastes impressions on someone who has already seen (and likely already reacted to, or ignored) the message, while also risking ad fatigue and a negative brand impression. Capping delivery to once per session keeps exposure fresh without needlessly inflating impression counts that don't translate into additional attention or recall.

Session-based delivery is typically used together with broader frequency capping strategies (for example, a maximum of three impressions per user per day across all creatives) rather than as a standalone rule, since a session cap alone doesn't prevent over-exposure across multiple sessions in the same day.
