Who's Better at Selling Stuff: Internet Stars or Famous Faces?

Wed Jul 02 2025

People often wonder who sells products better: famous people from TV and movies or influencers from social media. Both types are popular with advertisers, but research shows mixed results on who works best. The truth is, it depends on the situation.

The Study

A recent study dug into this question. It looked at how well different factors make an endorsement work. These factors include:

  • Fit - How well the endorser fits the product
  • Popularity - Their fame and recognition
  • Self-congruity - How much people feel like them
  • Similarity - How similar they are to the audience
  • Likeability - How much people like them

The Findings

The study used four experiments with 473 people. It found that fit, popularity, self-congruity, and similarity matter. But surprisingly, likeability did not. This means that who sells a product well isn't just about being liked. It's about matching the right person to the right product and audience.

The Implications

This research helps advertisers pick better endorsers. It shows that there's no one-size-fits-all answer. The best choice depends on the specific context.

A Thought to Consider

But here's a thought: why do we care so much about who endorses a product? Is it really about the person, or is it about the story they tell? Maybe it's time to think differently about how we see endorsements.

    What if the only endorsement context was a zombie apocalypse: would you trust a social media influencer or a traditional celebrity to recommend the best survival gear?
    How do product-endorser fit, popularity, self-congruity, and similarity impact the effectiveness of social media influencers versus traditional celebrities in endorsements?
    What are the ethical implications of using product-endorser fit, popularity, self-congruity, and similarity to manipulate consumer attitudes toward endorsements?
