In social media, directed links can signify a variety of things, including close friendships, shared hobbies, or even a love of the latest news or celebrity rumor. Such directed links control the information flow and so show how much power a user has over others—a concept that is essential to sociology and viral marketing. The emergence of social media has totally changed how individuals participate, interact, and communicate. In order to facilitate increased outreach and influence, these platforms are crucial. The practice of paying people to promote a product or service on social media is known as influencer marketing. Influencer marketing, which involves finding, enlisting, and supporting people who start discussions with a brand's customers, is a developing trend in PR campaigns. Influencer marketing is becoming more popular as a result of word-of-mouth marketing trends. Organizations are recognising the potential of influencers in influencing a purchasing choice as customers use social media platforms. Finding the proper kind of influencer who would provide curated tips, stories, and recommendations to interest the audience is essential for effective influencer marketing.
