I am really struggling with finding relevant hashtags that I can use in my posts on IG.

Hi there! Not sure if you’ve given this a try yet, but using Klear to find top influencers in your niche and then using the same/similar hashtags as they are using on their posts might be a solid tactic.

Also, tools like Hashtagify.me could be of use. I haven’t personally used it but known those who have and like it.
