Definition of influencers
Influencers are individuals who can impact the opinions, attitudes, and purchasing decisions of their followers through their social media presence. These individuals can be celebrities, industry experts, bloggers, or regular people who have gained a significant following on platforms such as Facebook, Instagram and YouTube.
Influencers typically create content that is engaging, informative, and authentic, and they work with brands to promote products and services to their followers. They can be compensated for their work either through monetary payment or through receiving free products or services.
Diverse types of influencers

The definition of influencer tiers varies among different countries because of the population. In this article, we use Hong Kong as an example to illustrate how influencer tiers can vary based on population size. Hong Kong, with its relatively small population compared to larger countries, provides a unique perspective on the classification of influencer tiers.
The different tiers of influencers are typically defined based on their reach, engagement, and follower count. Here are the general definitions for each tier:
Top Influencers: These are typically the most well-known and influential individuals on social media platforms, often with millions of followers. They are usually celebrities or high-profile personalities, and their endorsement can have a significant impact on a brand’s visibility and reputation.
Macro Influencers: These influencers have a large following, typically ranging from 100,000 to 1 million followers. They have a broad reach and can help brands reach a wider audience. They are often industry experts, thought leaders, or social media stars.
Middle-Tier Influencers: These influencers have a following ranging from 30,000 to 100,000 followers. They are often experts in a specific niche and have a dedicated following that is highly engaged with their content.
Micro Influencers: These influencers have a smaller following than middle-tier influencers, typically ranging from 10,000 to 30,000 followers. They have a highly engaged audience that trusts their opinions and recommendations.
Nano Influencers: These influencers have a very small following, typically ranging from 1,000 to 10,000 followers. They are often everyday people who are passionate about a particular topic and have a highly engaged community that values their insights and opinions.
