Is a sidebar in WordPress primarily used for displaying additional information or links?

A sidebar in WordPress is indeed primarily used for displaying additional information or links. This feature serves as a space alongside the main content area of a website, where site owners can place widgets, advertisements, recent posts, categories, or any other relevant content that enhances the user experience but is not the core focus of the page. Because sidebars are typically standardized across multiple pages of a website, they help maintain a consistent look and provide useful navigation options. This additional content can lead to a better user experience by making it easier for visitors to find related information or navigate the site.
