Choosing between celebrities on social media is not an easy thing to do, and it depends on a lot of things, including:

For example, if it is a restaurant, then it is better to find people who are specialized rather than someone who does not have experience in this field, in addition to your knowledge of statistics that they often lie about.

You have to see the interaction whether it reaches 10% or not.

It also depends on the person themselves and the way that people view them. You have to know this by following them for a period of time to see how people interact with them.

Finally, distributing your money to a large number of influencers rather than one big influencer considered the best way. The amount you pay to a celebrity with a million followers may be equal to 200 or more celebrities with 10,000 followers or less.
