If you’re depending on instagram for visibility and growth, then you need 10% or better at all times in order for Instagram to give you that visibility. As someone already said it is 10-12% from your follower count. If someone has thousands of followers and 100 likes usually it is a sign of bought followers.
What happens after 10k followers on Instagram?
Once you have 10k followers, Instagram will make it easier for you to get people to your website via Stories with the swipe up to link feature. Swipe up is the only way to get a direct link from your Instagram to your other web properties. And, it’s available in STORIES, if you have 10k followers.
