What is Influencer Marketing?

Influencer marketing is a type of marketing strategy that includes a collaboration between brands and influencers for promoting their products and services. These influencers generally have a large audience or a niche audience. They can influence the purchasing decision of customers.

Impact on Customer Behaviour

Influencer marketing impacts customer behaviour in various ways, such as

Awareness: Influencers introduce customers to new products and trends that they might not have encountered before. Their engaging content generates demand, especially among niche customers.

It influences their purchase decisions. They trust influencers, and their recommendations hold value to them.
Purchase Decision: Influencers can manipulate the purchasing decisions of their audience. By providing first-hand experience, influencers can make the audience buy a certain product. For example, if an influencer has purchased a shirt from a particular brand, then the interest for that product will increase and can make their customers buy it.
Social Proof: Influencers create social proof by showcasing how they use that product and promoting it in their social circle. This helps in creating a fear of missing out (FOMO).
