Planning Site Structure
Take time to consider your site’s purpose and planned content well in advance. This will drive how you design the structure of the site. A good site structure supports easy navigation and content discovery for your site visitors and supports various AEM features such as multisite management and translation.
Site Templates
Because site structure is so important to the success of a site, it is convenient to have predefined structures available to quickly deploy a new site based on a set of existing standards. Site templates are a way to combine basic site content into a convenient and reusable package.
Site templates generally contain base site content and structure and site styling information to get new site started quickly. Templates are powerful because they are reusable and customizable. And since you can have multiple templates available in your AEM installation, you have the flexibility to create different sites to meet various business needs.
