Celebrities and influencers are two different types of public figures that brands can collaborate with for marketing purposes. Celebrities are typically well-known individuals who have achieved fame through their talents, such as acting, singing, or sports. Influencers, on the other hand, are individuals who have established a significant social media following and influence like bloggers, YouTubers, or online personalities. One key difference between celebrities and influencers is their level of engagement with their audience. Celebrities often have a more passive relationship with their fans, while influencers have a more active and engaged community.
