Like you, customers have their own objectives when they visit your website. It could be to find a product, find a service, learn about you or even, to only get your contact details.
But, what if you had too much trouble finding the information or understanding it?
Will you refer your colleagues or friends this website? Maybe. Probably. Possibly. Well, stop it.
Start providing information your customers want and can find easily in your website. Start a sitemap.
You’re halfway to design a website made for users. :)
