It's pretty easy.
Choose between a single page or multi-page design. A single-page website is a site with a single page. This page is scrolled down to view information. This is a modern and very popular choice. Information is displayed in sections, with a header on top directing users. A multi-page site allows you to have individual pages for all types of content. There are individual pages for things like a contact form, an about me page, and a services page.
Surveys, stores, and galleries galore. Add whatever you like to your website. Allow your visors to purchase your services, give their feedback, download your music or podcasts, and much more. Maybe you want a membership system, where your most dedicated fans can interact and build up a community.
Pick your layout, color scheme, shapes, flow, and much more. Make your website stand out and reflect the business you're looking to grow.
Slap on a domain name, and you're done! Congrats on your new, striking, powerful website.
