Instagram Captions are indispensable because they give you more information relating to your bio and pics. After graphics and headlines, captions remain the third most viewed portion of most printed pages. They are like headings. If you can construct a well-designed caption, there is a greater chance that your Instagram post/picture will receive a relatively high engagement.
