Drupal is a powerful, open-source Content Management System (CMS) used to build and manage websites. It is highly flexible and scalable, making it suitable for everything from simple blogs to complex enterprise sites. On shared hosting, Drupal offers a robust platform without the need for dedicated servers, keeping costs low.

Key advantages of using Drupal include:

• Strong Security: Regular updates and a dedicated security team protect your site.
• Vast Module Library: Thousands of free modules (extensions) add features like e-commerce, SEO tools, and forms.
• Customization: With numerous themes and the ability to create custom content types, you can design a unique website.

For beginners, many shared hosting providers offer one-click installers (like Softaculous) to set up Drupal quickly. Ensure your hosting plan meets Drupal's requirements, typically including PHP, MySQL/MariaDB, and sufficient resources. While it has a steeper learning curve than some CMSs, Drupal's power and community support make it an excellent choice for growing websites on shared hosting.
