Well, it’s partly commonsense, right?
E.g., are your follower/fans growing? Do they engage with your posts? Do they contribute posts of their own? Is the number of your community screenings increasing?

Kami Huyse has created this nifty white paper to guide you. She’s a PR professional, founder of Zoetica Media. As you’re reading, just substitute “film” or “filmmaker” (yes, you need to be thinking about your personal brand) for “organization.”
