Which of the following is not an available SAS Target Audience type?

Sequence targeting is not an available SAS Target Audience type. SAS (Software as a Service) platforms like Amazon Ad Server offer various targeting options to reach specific audiences effectively. Geo-targeting allows advertisers to reach users based on their geographic location. Retargeting (or remarketing) targets users who have previously interacted with an advertiser's website or app. Contextual targeting places ads on web pages or apps with content relevant to the ad. While sequence targeting (delivering ads in a specific order) is a common strategy in ad tech, it's typically a feature of campaign management or ad serving, not a primary audience type in the same classification as the others within SAS platforms.
