5. Post-purchase behaviour
In brief, customers will compare products with their previous expectations and will be either satisfied or dissatisfied. Therefore, these stages are critical in retaining customers. This can greatly affect the decision process for similar purchases from the same company in the future, having a knock-on effect at the information search stage and evaluation of alternatives stage. If your customer is satisfied, this will result in brand loyalty, and the Information search and Evaluation of alternative stages will often be fast-tracked or skipped altogether.
