One of the most important tools behind Instagram is the hashtag. Knowing what and how often to hashtag is key. A neat trick to do is right after you post a picture write as a comment a series of Hashtags, after including about 5 or so *’s.
This pushes the hashtags further down your comment so they won’t be obivously seen. You should then include about a dozen or so hashtags related towards your business along with some relevant to towards the picture.
