Why do you think people want to buy celebrity endorsed products?
It’s not just the products celebrities and influencers are selling, it’s the lifestyle. If a celebrity looks good, people might be interested in what diet they are on, or what care treatment they use. If a celebrity makes their living through music and recommends a technical product or another brand, you’re likely to feel some trust in their judgement. The idea behind this kind of marketing is that if you like a celebrity, you’ll want to be like them – if it is good enough for them, it is good enough for you!
Celebrity faces are everywhere. Seeing them with an item develops recognition and trust in the products that they are seen with.
