Improving accessibility can positively affect your website's load time and performance. Many accessibility guidelines, such as optimizing images, using proper headings, and ensuring clean code, naturally lead to a more efficient website. This can decrease page load times and improve performance. However, it's important to implement accessibility features correctly, as some complex solutions, if not optimized, could add to the load time. Overall, when accessibility features are properly integrated, they tend to enhance the site's performance.
