Abstract: Open any social media feed and you will be three scrolls away from someone recommending a product. Maybe it is a fitness creator talking about a protein supplement they have apparently been drinking for years. Maybe it is a tech reviewer giving their honest take on a new pair of headphones. Maybe it is a home cook walking you through a recipe that happens to feature a brand of olive oil front and centre. Some of these are purely organic. Most have a commercial arrangement behind them. And yet the way they land with audiences — the feeling of a recommendation from someone you have chosen to follow — is fundamentally different from the way a traditional advertisement lands. That difference is what this paper is about. The central question here is not simply whether influencer marketing increases brand awareness. The evidence that it does is well-established enough to need no more proving. The more useful question — and the one this paper addresses — is how it builds awareness, through which mechanisms, and whether certain types of influencer campaigns produce stronger or more durable awareness outcomes than others. The short answer is yes, and the differences are large enough to matter significantly for how brands should be allocating their influencer budgets. Through a structured review of the academic literature and synthesis of empirical findings across product categories, this paper examines the role of influencer tier, content authenticity, audience trust, and content format in shaping brand awareness at different points on the recognition-to-consideration spectrum. The practical output is a framework that gives marketing managers a clearer basis for influencer selection decisions than gut feel or follower count alone currently provides.
