When you post photos on Instagram, you probably think your followers see your photos and hopefully click Like. But that is not how Instagram works – at all.
Instagram uses an algorithm to determine when your photos are shown, and to whom. Similarly, the algorithm selects what photos you see from your friends.
When you make an initial post, IG “market tests” your post to a subset of your followers. If they interact with the photo, then IG will show it to more people. If interaction is minimal, then your post’s visibility will be drastically cut to the point it is no longer being seen.
Combined with aspects of the secret IG algorithm, your posts may no longer appear on hashtag searches either, rendering your account invisible.
Once the IG algorithm has flagged your account as being, effectively, “low engagement/boring”, the visibility of your posts and your account itself may largely vanish from view.
