Can celebrity endorsements be tagged as ‘influencer marketing’?

No. Celebrity endorsements are different from ‘influencer marketing’ as influencers have smaller audience outreach than celebrities. These people have the largest number of followers and are famous people in their respective fields. On the other hand, brand association with celebrities adds to the brand value and brand image. Influencers mainly target a niche audience with their content whereas celebrities reach out to a much wide audience base.
