Website ergonomics is critical for a high-ranking website. Making sure your layout is easy to navigate is key to a happy visitor. And when visitors are happy, you are happy, as they will stay on your website longer and buy more things.
The right theme can make a big difference. Most themes on WordPress and Shopify are mobile-friendly, so that’s not the issue, but what you have to consider is the ease of navigation for your visitors.
Picking a theme that’s minimal is becoming more and more popular, as it eases loading times (good for SEO), and makes users feel more comfortable on the site. If there’s too much going on, you risk having your visitor leave the site prematurely.
