Howdy, as far as I'm concerned, at the moment the best CMSs for small business websites are Wordpress and Jumla. Wordpress is a free, open-source platform that works best for both small and large business websites. With many benefits such as low maintenance costs, a large set of plugins, SEO-friendly, user-friendly, beautiful free themes and extensive customization options, Wordpress is the first choice for users to launch and run a website. But if these platforms don't suit you, take a look at cms wordpress alternatives and maybe you'll choose one that will be fully suited to your needs.
