1. The long tail theory can be applied to the use of hashtags in social media as we can choose from a varied array of hashtags those that adapt best and describe our content in the most detailed way. This way, as the theory explains, the sum of the users we get from those hashtags will be equal or higher than the sum we would have gotten from using general hashtags.
Specialized hashtags are much better to capture the audience we want to capture, as they differentiate our posts and bring in a more select audience, as opposed to the general ones which may be more popular but are also overcrowded and will in turn make your posts less relevant and/or attract a group of people you were not looking for.
So, to have this advantage and get the right kind of visibility, one could, for example, use 2-3 general hashtags and 7-8 niche/specific hashtags.
