Instagram highlights are the little circles at the top of people’s profiles with different titles like “Travel” or “Favourites.” It’s actually a way to organise your content and make your profile more visually appealing. Adding a unique cover photo to each of your Highlights can add a touch of personality and style to your page. You can choose from various designs and colours or even create your own. They are basically a collection of your best Instagram Stories that you can save and display on your profile for others to see. You can think of them as a highlight reel of your best Instagram content. 

Example 

For example, if you have a highlight dedicated to your travels, you can add a corresponding image of a globe or a map. When someone clicks on your highlight, they can see all the stories you have added to that particular category.
