In today’s social media-centric world, influencers are the stars, wielding incredible power and influence over their followers. From promoting the latest product to showcasing the newest fashion trend, influencers have become a crucial marketing tool for brands looking to reach their target audience. 

But not all influencers are created equal. This article explores the different types of influencers, from nano-influencers to celebrity-level influencers and everything in between. It also discusses the various channels through which influencers operate, as well as their niches and specialties. 

Whether you’re looking to launch a new product or promote your services to millions, this comprehensive guide will help you navigate the world of influencers and find the perfect fit for your brand’s needs.

What is an influencer?

An influencer is someone who has earned a trusted voice within a specific niche or among a particular audience by showcasing their expertise on their personal channels, be it a blog, social media, or website. 

These charismatic individuals usually share their authentic experiences with a product or service, demonstrating its use through engaging posts or a brief series. 

Partnering with the perfect influencer can be a game-changer for your brand. They can connect you with your ideal audience, amplify your brand’s visibility, and supercharge your digital marketing strategies.

A research study published in the Journal of Marketing shows that reallocating spending on influencer marketing campaign can result in a 16.6% increase in engagement.

Types of influencers by size

The size of an influencer’s following is one of the most significant factors when selecting the right influencers for your brand. Here are four different types of influencers by size:


Nano-influencers are relatable everyday people with a modest yet dedicated follower count of 1,000 to 10,000 people. They usually concentrate on a specific niche. By collaborating with a nano-influencer who aligns with your brand, you can tap into a highly targeted audience that will likely be genuinely interested in your offer.

These smaller influencers are hidden gems, known for generating warm leads that often result in higher conversion rates than their more prominent counterparts. Despite their smaller reach, they often boast the highest engagement rate, connecting with their followers like trusted friends and engaging in personal conversations. 

They’re usually easy to approach and collaborate with, and their compensation requirements tend to be more modest. So, they’re extremely easy to access if you fit their niche, even for small and new businesses. Some of them may even be your customers!

However, some challenges exist, like finding the right fit among the vast pool of nano-influencers and dealing with their inexperience compared to established influencers. Nano-influencers will generally only promote brands that fit in the niche they’re building, and they can sometimes be difficult to find.

Micro-influencers are a sweet spot in the influencer world, boasting a following of 10,000 to 100,000 people.  These influencers have carved out a specific area of interest, and their loyal audience sees them as go-to authorities in their field. So, if they fit your niche, you’ll gain access to an audience that’s likely to be interested in your products.

Like nano-influencers, micro-influencers drive high engagement levels and conversion rates because their follower base is very tight-knit. They connect with followers like trusted friends (but not as tightly as nano-influencers do, due to the slightly larger audience).

Partnering with micro-influencers provides you with a more extensive reach than nano-influencers while still tapping into an engaged and highly targeted follower base. They’re still relatively easy to connect with and leverage, even if you have a smaller business. But you might have a harder time finding micro-influencers, compared to influencers with higher follower counts.

Macro-influencers are a distinguished tier in the influencer world, bridging the gap between micro-influencers and celebrity influencers with a follower count ranging from 100,000 to 1 million people. As a category, some macro-influencers have niche expertise and others have broader appeal, making these influencers an attractive choice if you want to benefit from both worlds. 

These influencers offer a compelling balance between the expansive reach of celebrity influencers and the more intimate engagement of micro-influencers. Their considerable influence makes them an attractive choice if you want to reach a wider audience while maintaining a sense of authenticity and credibility.

Although they may not be as readily accessible as micro or nano-influencers, macro-influencers’ impressive following and reputation can significantly impact your brand’s visibility and influencer marketing efforts. Plus, macro-influencers are generally easy to find.

Celebrity-level influencers

Celebrity influencers are the shining stars of the influencer universe, boasting over a million followers. These captivating figures include both traditional celebrities and social media sensations who have climbed the ladder of fame through engaging content. 

Whether they stick to a specific niche or explore a wide range of topics, the influence of these mega influencers is undeniable. A Pipslay study reveals that celebrity endorsements influence the behavior of 59% of Americans.

With their immense reach, celebrity influencers offer unparalleled exposure, making them the most sought-after and often the most expensive option to make a significant splash in your marketing strategy. 

Securing a partnership with a celebrity influencer can be challenging yet highly rewarding. Collaborating with a celebrity influencer lets you tap into their vast following, harness their star power, and boost your brand’s image in the eyes of millions. 

If you’re a larger brand who can afford a celebrity’s promotion, or you get lucky and a celebrity promotes you before you even reach out, you’ll enjoy an extremely wide reach thanks to a celebrity influencer. 

Still, keep in mind that celebrities’ engagement from followers is usually low, especially since celebrities don’t reply to comments or have conversations with followers very often. And celebrity influencers are usually out of reach if you’re a small to medium-sized business, unless the celebrity first falls in love with your brand on their own.

Types of influencers by channel

In addition to the size of an influencer’s following, the channel they use to reach their audience and promote your brand is also essential. Here are the different types of influencers by channel:

The blogger

Bloggers are known for their in-depth reviews and thoughtful insights on products and services through their long-form content. They artfully weave links to your offerings within the context of their posts, guiding readers to your products and enhancing your SEO efforts. 

By sharing their genuine experiences and opinions, bloggers create a personal connection with their audience, making their recommendations more trustworthy and engaging.

The expert influencer

Expert influencers are the subject matter experts in their respective fields, like dentists who vouch for a particular toothbrush model or fitness gurus endorsing top-notch workout equipment. 

While they might not always have a massive blog or social media presence, their word carries weight. Their seal of approval lends credibility to your brand and reassures potential customers of your product’s quality, making their endorsement a valuable asset.

Expanded types of influencers

Besides the categories mentioned earlier, you can also classify influencers based on their promotional approach:

The affiliate influencer

Working with influencers usually focuses on tracking campaign reach and engagement rate rather than direct sales. However, without a trackable link, it’s tough to determine if the influencer’s branded posts are actually driving sales. That’s where affiliate influencers come in, offering you the perfect combination of trackable affiliate links and expansive social reach.

Affiliate influencers seamlessly integrate affiliate links into their content or social media bios, leading followers to your website. When someone clicks the link and makes a purchase, the responsible affiliate earns a cash commission.

This approach ensures you compensate influencers based on their performance, helping you invest wisely in generating leads and customers. You won’t have to spend blindly on influencers before they create any leads and customers. Plus, you can attach discounts to influencer-affiliates’ links, to add another motivation for leads to make the purchase

With the help of affiliate software, you can set up a well-structured affiliate influencer program.

The ambassador

Brand ambassadors genuinely adore your product or services and take the initiative to promote them consistently and passionately over time. They seamlessly weave your products into their everyday lives and share their authentic experiences online and offline. 

They regularly post about your brand on social media, represent you at events, and become natural extensions of your brand through their interactions. Their genuine enthusiasm for your product resonates with their audience, creating a lasting, positive impact on your brand’s image.

If an influencer knows and loves your product, wants to keep promoting it in the long term, and starts to share that love for you repeatedly and without prompting, their relationship with you evolves to that of a brand ambassador.
You can then reach out and make the ambassadorship official with a longer-term contract.
