Effectively organizing hashtags on Instagram: A study of library-related captions

Introduction. Little scientific attention has been paid to outlining the communicating function of hashtags on Instagram. The present study aims to fill this gap by analysing hashtag organization. Practical insights into user engagement, community building, and big data utilisation in the context of libraries are discussed.Method. To achieve a valid result, 2.5 million captions on Instagram with library-related content were collected.Analysis. Quantitative analyses were carried out with the statistical add-in packages in Python 3.0.Results. For captions with one hashtag included, putting it in the middle results in more likes and comments; for captions composed of more than 80% of hashtags, it is advisable to use more words than having a caption full of hashtags; for captions composed of less than 80% of hashtags, placing all hashtags consecutively at the beginning is not recommended as this is more likely to result in zero comments.Conclusion. It is concluded that placing hashtag(s) in the front of the caption should be avoided; it is not wise to use as many hashtags as possible. More effort should be made to better organize hashtags in captions because their location has an influence on attracting comments and likes.
