There are many tools you can use to create websites!
Here's a list a some of the easiest to use and implement for your business.
Google Sites is an app that's a part of Google Workspace (formerly G Suite), which is a group of Google's business productivity apps, including Gmail, Calendar, Drive, Docs, Sheets, Slides, Meet, and more.
Google Workspace is free for anyone with a Google account to access and use, but there there are a variety of paid Workplace subscriptions that range from $6 to $18 per month that offer additional business-level features, including a custom domain for your Google Site.
But you don't need a paid Google Workspace account to access and use Google Sites. If you have a Google account, navigate to Google Sites, then select the plus sign to create a new site. If you don't already have a Google Account, create your new Google account in order to use Sites.
Your site's domain will be https://sites.google.com/view/[your site's name], but you also have the opportunity to purchase a custom domain or use a domain you already purchased from a domain registrar.
