AdOpt has its own scanner (within Banner's settings: Tag scan) that helps you identify all the tags automatically.
AdOpt suggests a categorization or classification of the tags identified, according to a market standard and also the user preference of category for that tag. For example, the tag "Facebook" is usually categorized as "Marketing".
After that, it is important that you set the Cookie Blocking on every tag, from all categories, except the "Required" ones. Look for the guides in the "Essential settings" section and the "Blocking" field to identify all the possibilities.
