Tracking Covid-19 in the US

Hey there. I built a site to track Covid-19 cases in the US (https://ncov19us.com)
I have been steadily gaining new users daily. I would like to grow this site and make it a go-to for Covid-19 stats. Most of my traffic is currently from social media. I am working on SEO as well.

Take a look and let me know your thoughts. What strategies can I take to get this to grow?
