A social media influencer's role is to create content that earns an audience's trust and to use that trust to shape what people think about and buy. In practice, influencers plan, film and post content on platforms such as TikTok, Instagram and YouTube, engage with their followers, and partner with brands to promote products in a way that feels like a recommendation rather than an ad.
What is an influencer's role?
An influencer plays three roles at once:
- Creator: produces videos, photos, livestreams and posts.
- Community builder: grows and keeps an audience that cares about a niche such as beauty, fitness, food, tech or parenting.
- Trusted recommender: introduces products and ideas to that audience, often in paid partnerships.
What does a social media influencer do day to day?
- Plans content ideas and follows platform trends.
- Films, edits and publishes posts, Reels, TikToks or videos.
- Replies to comments and messages and runs livestreams.
- Reviews analytics: reach, views, engagement and audience data.
- Pitches brands and negotiates partnerships.
- Creates sponsored content to a brand brief, gets it approved and discloses it as an ad.
- Reports campaign results to brand partners.
Types of social media influencers
Influencers are often grouped by audience size. These tiers are common industry conventions, not fixed rules:
- Nano-influencers: about 1,000 to 10,000 followers; very close communities.
- Micro-influencers: about 10,000 to 100,000 followers; strong niche trust. See what is a micro-influencer.
- Mid-tier influencers: about 100,000 to 500,000 followers.
- Macro-influencers: about 500,000 to 1 million followers.
- Mega-influencers and celebrities: over 1 million followers; broad reach, less niche trust.
They can also be grouped by niche or by format, for example streamers, podcasters, bloggers and short-form video creators.

Influencer vs. UGC creator: what is the difference?
An influencer is paid for content and for access to their audience: the post goes on their own account. A UGC creator is paid for the content only: the brand gets the video to run in its own ads and channels, and the creator's follower count matters less. For paid social, many brands now buy UGC videos and run them as ads. NugVerse connects brands with real, verified UGC creators, from $650 per video with no subscription and usage rights cleared for ads.
