5 Types of Influencers and Their Role in the Marketing Funnel

Influencer marketing isn’t about finding the person with the biggest audience. It’s about finding the person who can influence your audience to take action. 

There are different types of influencers, and each plays a different role in the marketing funnel. Sure, choosing an influencer with a large following may help you reach more people, but it won’t necessarily lead to conversions. If your goal is conversions, you’ll see stronger results by choosing the influencer type whose audience is more likely to engage and take action. That may mean working with influencers who have fewer followers but more influence over the audience you want to reach.

What is a Social Media Influencer?

A social media influencer is someone who has built a following on platforms like Instagram, TikTok, or YouTube and earned credibility and trust with that audience. They often partner with brands to promote products or services, and their content can shape their audience’s opinions, behaviors, and purchasing decisions.

Some influencers started as celebrities, like Kim Kardashian or Dwayne “The Rock” Johnson. Others built their audience organically by consistently creating content that resonated on social platforms, like Emma Chamberlain, MrBeast, and Emily Mariko.

Regardless of how they got their following, their value to brands comes from how well they connect with their audience and influence them to take action.

Why Influencer Type Matters

Not every influencer is the right fit for every campaign. It’s easy to assume that a bigger following = a bigger impact, but that’s not always the case. What matters most is fit: brand fit, audience fit, campaign fit, and budget fit. 

Different influencers bring different strengths:

• Some help brands gain reach and show up in cultural moments.
• Some build trust through stronger audience relationships.
• Some produce the most authentic, high-quality content.
• Some are built to drive actions like conversions.

Influencer marketing is an investment, and understanding these differences helps you make smarter budget decisions. You avoid overpaying for reach you don’t need or overlooking creators who drive real performance.

WITHIN offers a full-funnel influencer marketing service to help brands identify and activate the creators who are best equipped to deliver on their goals, whether that’s awareness, content, or conversion.

What are the 5 Types of Influencers?

The influencer landscape has changed dramatically over the past few years. As social media has become a bigger part of everyday life and one video can make someone go viral, the types of influencers have expanded. 

Influencers are often grouped by follower count. Which is a helpful starting point, but it doesn’t tell the full story. You also need to consider the quality of their audience, the type of content they create, and how closely they align with your brand.

Influencer Tier	Follower Count	Why Brands Partner With Them	Key Strengths
Mega	1M+	Large-scale awareness	Maximum reach and cultural visibility
Macro	500K – 1M	Awareness and early consideration	Broad reach with professional, high-quality content
Mid-Tier	100K – 500K	Consideration and engagement	Balanced reach with strong audience trust
Micro	10K – 100K	Engagement and conversions	High-trust content that drives action
Nano	1K – 10K	Social proof and community trust	Authentic, real-world credibility at a local or niche level

 

What is a Mega-Influencer?  (1 million+ followers)

Mega influencers are global icons, athletes, top creators, and celebrities with more than 1 million followers. Think household names like Selena Gomez, Alix Earle, or Cristiano Ronaldo.

They’re most effective for driving visibility at scale, since they can quickly put a brand in front of a massive audience. But because their audiences are so broad, engagement and conversions are often lower than with smaller creators, and recommendations can feel less personal.

What is a Macro-Influencer? (500K to 1 million followers)

Macro influencers have between 500K and 1 million followers and are often full-time creators. They produce polished, high-quality content and typically have influence within broad lifestyle categories. Think beauty creators like @hyram, fitness creators like @alextoussaint25, or fashion creators like @acquired.style.

Compared to mega influencers, macro influencers still offer strong reach, but their audiences are more category-focused. This makes them effective for upper-funnel awareness and early consideration. They’re often seen as a “sweet spot” for brands, because they offer professional production value with a more focused and engaged audience than A-list celebrities.

What is a Mid-Tier Influencer? (100k-500k followers)

A mid-tier influencer is someone with 100K to 500K followers. They’ve built a clear audience around a specific interest or category and tend to see loyal audiences and consistent engagement as a result of that. Think creators like @sydneyadamsking, @cheflogant, or @mycityapartment.

Mid-tier influencers offer a balance between reach and relatability. They’re large enough to get a brand in front of a meaningful number of people, but still close enough to their audience to influence interest and consideration. Because of that, they’re often a good fit for campaigns where the goal is to move someone from awareness toward seriously considering a product.

What is a Micro-Influencer? (10K to 100K followers)

Micro influencers are creators with 10K to 100K followers who have built credibility around a specific topic, interest, or niche. They tend to have smaller but highly engaged audiences and are often seen as trusted voices, which makes their recommendations feel more personal and relevant.

Their content is typically educational or “how-to” demonstrations, making them a good fit for campaigns that need to explain products and drive conversions. While they don’t deliver the reach of larger creators, working with multiple micro influencers can generate stronger engagement and sales than a single post from a celebrity.

What is a Nano-Influencer? (fewer than 10K followers)

Nano influencers are creators with fewer than 10K followers who reach small, local, or highly niche communities. They’re typically everyday consumers rather than professional creators, which makes their content feel more natural and credible.

Brands work with nano influencers to build social proof and show products in real-life settings. While they don’t offer scale on their own, they can be effective for local activations and niche community building.

Choosing the Right Influencer Type for Your Brand

The right type of influencer for your brand depends on your goals, budget, and industry. Before even starting talent research, you have to determine what success looks like for your campaign:

• Are you trying to build awareness, traffic, or conversions?
• How will success be measured: reach, engagement, traffic, conversions, or brand lift?
• What type of content do you want: educational, testimonial, UGC-style, or polished creative?
• What platform will this campaign live on?

Then consider the constraints:

• Who does your audience already follow and trust?
• Will you need usage rights for paid media or long-term repurposing?
• What creator tiers does your budget realistically support?

Answering these questions helps you understand not just which creators to work with, but what role they’ll play in your broader campaign strategy and what outcomes to measure them on.

Most brands get the best results by using a mix of influencer types. Mega and Macro influencers help reach new audiences and build top-of-funnel momentum. Micro and Nano creators tend to have stronger trust with their followers, making them effective for engagement and conversion. Using a combination gives your campaign coverage across the full funnel.

A simple way to evaluate influencer fit based on your campaign goals:

• Goal = Awareness → Mega or Macro
• Goal = Engagement → Mid or Micro
• Goal = Conversion → Micro or Nano
• Goal = Social Proof = Nano

Designing a Full-Funnel Influencer Strategy

The most important thing to remember when building an influencer campaign is to match the influencer type to the outcome you want, not just the size of their audience. Thinking in tiers instead of silos helps brands choose creators more intentionally and build campaigns that balance reach, relevance, and trust to drive results across the funnel.
