Is your website properly configured for individuals with disabilities? This can include font contrast, text magnification, image descriptions, etc.
There are some fairly straightforward tools to help in the process. Equalweb has a free WordPress-ready tool which I use on Host1help1.com. Do a quick scan here: https://accessibe.com/accessscan to see how your website scores.
Bonus: You can receive a tax credit for the cost to remove barriers that prevent a business from being accessible to or usable by individuals with disabilities. Consult your tax professional and read about the Form 8826 here: https://www.irs.gov/forms-pubs/about-form-8826
