Bu çalışma, influencer pazarlamasının marka farkındalığı ve satın alma niyeti üzerindeki etkisini; influencer güvenilirliğinin ve uzmanlığının moderatör rolüne odaklanarak incelemektedir. Nicel bir yaklaşım ile Türkiye'deki genç tüketicilerden toplanan veriler doğrultusunda elde edilen bulgular, influencer pazarlamasının hem marka farkındalığını hem de satın alma niyetini önemli ölçüde etkilediğini göstermektedir. Moderatör analiz sonucu, influencer güvenilirliğinin influencer pazarlamasının ilgili değişkenler üzerindeki etkilerini güçlendirdiğini, ancak influencer uzmanlığının moderatör bir etkiye sahip olmadığını göstermektedir. Genel olarak, sonuçlar tüketici tepkilerini şekillendirmede güvenilirliğin merkezi önemini vurgulamakta ve influencer pazarlamasının marka farkındalığı oluşturma ve sürdürme ile satın alma niyetini teşvik etmedeki rolünün altını çizmektedir.
