Page builders like Elementor, Divi, and WPBakery allow users to build page layouts visually without writing code, using drag-and-drop interfaces. While accessible for beginners, page builders often generate bloated, inefficient code that negatively impacts site speed, Core Web Vitals scores, and long-term maintainability. Professional WordPress developers frequently build custom-coded themes instead, achieving cleaner code, better performance, and greater design precision than page builders can provide.
