What function does the Sitefinity page builder serve?

The Sitefinity page builder primarily serves to empower users to design pages visually. This feature is integral to enhancing user experience, as it allows non-technical users to create and modify page layouts without needing to write code. The visual interface enables drag-and-drop functionality, allowing for easy placement of widgets, content blocks, and multimedia elements on a page. This simplifies the process of web design, making it accessible to marketing teams or content creators who may not have a strong coding background.

The other options, while they may touch upon aspects of Sitefinity, do not accurately capture the primary functionality of the page builder. Coding new pages from scratch requires a level of technical expertise that the page builder aims to minimize. Providing templates for e-commerce functionalities focuses on a specific area rather than the broader capability of visual design. Similarly, automatic image optimization, while beneficial for performance, is not a function tied to how users interact with the page builder itself for designing layouts.
