AIDA (marketing)

The AIDA marketing model is a model within the class known as hierarchy of effects models or hierarchical models, all of which imply that consumers move through a series of steps or stages when they make purchase decisions. These models are linear, sequential models built on an assumption that consumers move through a series of cognitive (thinking) and affective (feeling) stages culminating in a behavioural (doing e.g. purchase or trial) stage.
