Which of the below is NOT one of the three factors determining how an influencer can impact behavior?

The factor that influences an influencer's ability to impact behavior includes reach, engagement, and trustworthiness.

Reach refers to the number of people exposed to an influencer's content, which is crucial because a larger audience increases the potential for behavioral influence. Engagement reflects how effectively an influencer connects with their audience through likes, comments, and shares, further enhancing their impact. Trustworthiness is vital as it determines how much their audience believes in the influencer's credibility, making them more likely to act on recommendations.

Resonance, while it may relate to how well messages resonate with the audience, is not typically categorized as one of the core factors that directly shape behavior influence in this context. Understanding the distinction among these factors helps clarify how influencers operate and why brands choose specific individuals to represent them.
