What is a CMS?

A CMS or Content Management System refers to a software or application that uses a database or multiple databases to store and manage content. These are used by companies ranging from business to education to form, design, and manage their websites. With good CMS software backing your brand, your website will seem more attractive, rank better in SEO rankings, get more clicks, and as a result, will lead to more leads and business.

Most CMS services are open-source and therefore free and publicly available to anyone who wishes to use them- though additional paid features and memberships also come attached for special features and benefits. Below are listed the top 5 best open-source CMS services in 2021.
