Which of the following are influencer grouping factors?

Influencer grouping factors help categorize and organize influencers for effective partnership strategies. Partnership models define the type of collaboration (e.g., affiliate, sponsored content, brand ambassador), which is crucial for grouping. Content types (e.g., video, blog, static image) dictate the format of influencer output and audience engagement. Tiers (e.g., nano, micro, macro, celebrity) categorize influencers by follower count and reach, impacting potential campaign scale and cost. Social media outlet is a platform choice, not a grouping factor for the influencers themselves, as one influencer can use multiple outlets.
