Most platforms give you some data to check this. On Instagram, for example, you can look at reach and see how much of it came from people who do not follow you. On YouTube, there is a section that shows how many viewers are new versus returning. If the same small group is always engaging and no new names are appearing, the content is not spreading. Posting content that people want to share is usually what pushes it to new audiences. So do you think platforms give enough information to actually measure this well?
