Impact of Digital Marketing on Consumer Behavior : Analysing Social Media Influencers and SEO’s Role in Shaping Millennial Purchasing in Fashion Retail.

The contemporary fashion retail landscape has undergone a significant transformation due to the rapid expansion of digital marketing channels. Among various consumer segments, millennials typically defined as individuals born between 1981 and 1996 constitute a crucial target market for fashion brands, as they are digitally proficient, highly active on social media platforms, and strongly influenced by values and peer opinions. Within this digital environment, two prominent marketing instruments play a decisive role in shaping millennial consumer behaviour: influencer marketing on social media platforms and search engine optimization (SEO), which enhances brand visibility and accessibility during active online search processes. This study examines the underlying mechanisms through which these digital marketing strategies influence millennial consumers’ attitudes, trust formation, and purchase intentions in the fashion retail sector. Furthermore, the paper synthesizes existing empirical literature and proposes suitable research frameworks and managerial implications for fashion marketers. This paper examines how digital marketing, specifically social media influencers and search engine optimization (SEO) shapes millennial purchasing behaviour in fashion retail. Combining a structured literature review with proposed empirical methods and synthesized findings from recent industry reports and peer-reviewed studies, the paper shows that influencer content and search visibility act on different stages of the consumer decision journey: influencers increase discovery, trust, and affective engagement; SEO drives information search, comparison and purchase intent via visibility and perceived credibility. Practical implications for fashion retailers include an integrated influencer + SEO strategy, measurement approaches, and ethical considerations.
