What is the main purpose of supplementary content on a website?

The main purpose of supplementary content on a website is to provide additional context, information, and value to the main content. This type of content enhances the user experience by offering more depth or background that can help users better understand the primary topics discussed. It can include resources such as FAQs, related articles, infographics, charts, and videos that expand on the main subject, making the content more comprehensive and engaging.

Supplementary content not only enriches the overall content offering but can also support user engagement and retention by addressing questions or concerns that may arise as visitors explore the primary content. This ultimately creates a more informative and valuable experience for the audience, encouraging them to spend more time on the site and potentially leading to higher satisfaction with the content provided.
