To conclude, one page template design works well when you have a particular goal or want to encourage people to complete a given goal. It is also well-suited to mobile-first architecture. Multi-page template interface, on the other hand, helps you to expand your scope, stick to conventional navigation schemes, and improve your SEO strategy. 

There is no definitive guideline for deciding whether to design a one-page or multi-page website. The most important thing to remember is to focus on your content. Consider the information you need to get to the customers and how you can make the information as available as possible to them.
