There exist some solutions for this that overlay your webpage, and there is a heatmap to show where a user's cursor has traveled to. More popular areas show "hotter" in red, which could show how effective your changes are, or where you may want to center content you're trying to get users to notice around. I haven't directly worked with the data, but have seen the heatmaps from Hotjar on sites I've implemented (doing both frontend and backend development, but not involved in the design or SEO/marketing).
