When social media insights show content not delivered, it means your post was not shown to many people. This can happen if the platform thinks people are not interested in the post, or if the post did not get early likes, comments, or shares. Social media platforms test posts with a small group first, and if people react, they show it to more people. If there is no reaction, the post stops moving. This is why engagement is very important. Do you think engagement is now more important than followers?
