What is the definition of Endorsement Experiments?

Endorsement experiments? Well, picture this: a company wants to prove that their new coffee blend is the best in town. So, they team up with a famous influencer (who happens to have a questionable history of fake likes and followers) to give it a "trial run." The influencer, with their usual dramatic flair, claims it's their "new favorite" and starts raving about it. The experiment is live and we're all waiting to see if their hype translates into real sales.
