You share your posts one after the other without captioning, after a while people may start to lose interest. It is very important to write descriptive captions for your posts.
For example, it may not be enough to just use emojis or write "The view is beautiful..." when sharing a photo from a trip. You can write a nice caption with small explanations in many fields such as where you are, special information about the area you are in, what you do there etc.
