How do platforms collect and share creator’s data?

Whether you are a macro, micro, or even a nano influencer, it doesn’t matter; data is essential to share with brands information about your platforms.
What is your engagement rate? Where are your followers located? How many people do you reach on average with each post?
This data is very important to brands. That’s why it is crucial to educate yourself on what tools and methods you want to use to allow brands to access your data from your profile.
