As far as actually doing the nuts and bolts building and design of your site, you also have plenty of options. You can hire someone to design and code a website, or you can try your own hand (if you're a novice, The Best Courses for Learning How to Build Websites is an excellent starting point). You can use an online service to create web pages, or build it offline using a desktop software tool. Or, if you're a coding dynamo, use a plain text editor to create a site from scratch. How you mix and match these decisions depends on your skills, time, budget, and gumption.
A website is a collection of many types of content. Your website can contain a collection of content including blog posts, product descriptions, images that highlight your product, explainer videos that tell your story, and contact information. These different types of content have one thing in common. Each piece of content has seconds to capture the attention of your audience.
