What is one feature of Google Sites that helps customize a website?

One key feature of Google Sites that assists in customizing a website is the ability to upload images alongside having a structured page navigation system. Image uploads allow users to personalize their sites with visuals that reflect their content and brand, enhancing the overall aesthetic and engagement of the website. Page navigation is equally important, as it provides visitors with a clear and organized way to explore different sections of the site, making for a user-friendly experience. This combination of visual appeal and navigational ease is crucial for effective website customization, enabling users to present their information appealingly and intuitively.

The other options do not adequately highlight features that significantly contribute to customization in Google Sites. While automatic SEO settings and custom domains relate to improving a site's visibility and branding, they do not pertain specifically to customization. Pre-built templates can assist in starting a website but may limit creativity compared to the flexibility allowed by custom images and navigation options. Lastly, features like automatic content generation and text-to-speech do not directly enable users to customize the look and structure of their site, focusing instead on different aspects of content creation and accessibility.
