Who are influencers and why are they important?

The rise of social media platforms has significantly changed the dynamics of communication, marketing and social interaction. At the center of these changes are 'Influencers', a term we often encounter on platforms such as Instagram, YouTube and TikTok. But who are these influencers? How did they become so famous and what impact do they have on traditional marketing? Let's delve into these questions.

Who are 'influencers'?

Influencers are individuals who, through their online presence, have the power to influence the purchasing decisions and opinions of their audience, thanks to their expertise, popularity or reputation in a particular niche. They range from celebrities, industry experts, bloggers, content creators to everyday individuals who have cultivated a loyal following on social media. They regularly share content and interact with their followers, establishing a level of trust and influence.

How did they become so famous?

The rise of influencers corresponds with the rapid growth of social media. As platforms like Facebook, Instagram, YouTube, and TikTok have grown, so have individuals the opportunity to share content and gather followers. Their recipe for fame usually involves consistent content creation, authenticity, connection and engagement with their audience.

Many influencers have found their niche, told a unique story or provided valuable content that resonated with people, resulting in loyal and engaged followers. Over time, these followers came to see them as opinion leaders or trendsetters, which led to the growth of their influence.

Which social media has the most influencers?

While influencers exist on almost all social media platforms, Instagram, YouTube, and TikTok have the most prominent influencer populations.

Instagram, with its visually oriented platform, is the ideal place for fashion, fitness, travel and lifestyle influencers. YouTube, being a video sharing platform, is popular with influencers who create long-form content such as tutorials, reviews, vlogs and more. With its short-form video content, TikTok has proven to appeal to a younger demographic and has quickly become a breeding ground for new influencers, particularly in entertainment, dance and comedy.

How are influencers divided?

Influencers can be categorized based on the size of their follower base:

  1. Mega-influencers: these are top influencers, often celebrities, who have more than a million followers. They have a wide reach but lower engagement rates.
  2. Macro-influencers: These influencers usually have between 100,000 and 1 million followers. They often include bloggers, experts, and non-celebrities who have gained a significant following.
  3. Micro-influencers: These influencers have between 1,000 and 100,000 followers. They usually have very specific audiences and high engagement rates.
  4. Nano-influencers: These are everyday consumers who have less than 1,000 followers but have influence within their small community.

Each type of influencer has its strengths, and the choice between them depends on the marketing goals and budget of the brand.

How do they affect traditional marketing?

Influencers have reshaped traditional marketing in a significant way:

  1. Consumer confidence: Influencers, especially micro- and nano-influencers, often have a stronger relationship with their audience compared to traditional celebrities. This relationship can result in a higher level of trust and a greater influence on consumer behavior.
  2. Content creation: Influencers are skilled content creators. Brands can use this to create authentic and engaging promotional content.
  3. Target reach: Brands can reach a specific demographic or market segment by partnering with influencers who have a following in that niche.
  4. ROI: Influencer marketing can provide significant return on investment (ROI). Nielsen's research showed that influencer marketing returns €6.50 ROI for every €1 spent.

Influencers have become an integral part of modern marketing strategies, giving brands a more personal, authentic and effective way to reach consumers.


Influencers have emerged as a powerful force, transforming the ways brands connect with consumers. They are a product of the social media revolution and have gained fame by creating engaging, authentic content that resonates with their followers. Because platforms like Instagram, YouTube, and TikTok are hotbeds of influencer activity, they have significantly impacted traditional marketing, making it more personal and relatable. Understanding the influencer phenomenon is key to navigating the modern digital landscape, whether you're a brand, content creator or consumer.
