Best thing to get followers is sharing content that catches attention.
3 things to do:
1) Share large, high quality image / video content
2) Add proper HASHTAG ( this increases your chances in search )
3) Follow relevant people , like / comment / retweet their good stuff.
It is all about helping people with what they crave for on social media.
I follow this strategy for an gift shop, and it works well. I hope what I said will work for you as well. Focus > Engage > Get followers
