A survey research method was adopted for the study. The population comprised 1,185,169 residents of Enugu metropolis, from which a sample size of 400 respondents was determined using the Australian Sample Size Calculator.

The study concluded that celebrity endorsement remains a powerful marketing communication strategy capable of strengthening consumer attachment to brands and influencing long-term purchasing behaviour.
