When your content is seen as valuable, Instagram will prioritize it and show it to more of your followers within their home feeds. They will also show it more on their Explore page and possibly feature it as a Top Post if it gets high engagement in a relatively small amount of time.
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.
