What is a common type of SC that enhances user experience?

Navigation links are indeed a key element that enhances user experience on websites and applications. They provide users with a clear and intuitive pathway to access different sections or features of the site, making it easier to find information or complete tasks. Well-structured navigation improves usability by helping users understand the layout of the content and directing them to relevant areas without frustration or confusion.

High-quality paid ads, while potentially relevant for generating revenue, do not inherently improve user experience. Instead, they can sometimes detract from it if they disrupt the flow of information or if users perceive them as intrusive. Background music and sounds can also hinder the user experience, especially if they are unexpected or cannot be easily controlled by the user. Pop-up ads for promotions often interrupt the browsing experience and can lead to user annoyance or frustration, which negatively impacts overall satisfaction with the site.
