What is the role of Supplementary Content (SC) on a webpage?

Supplementary Content (SC) on a webpage plays a significant role in enhancing user experience and providing additional context or value to the main content. While SC can contribute positively to the overall quality of a webpage, it is not mandatory for achieving high ratings. Pages can still receive high ratings based primarily on their main content, even if they do not include supplementary elements.

SC may include features like related articles, user comments, or promotional content that enrich the user's interaction with the page. However, the core purpose of the primary content remains paramount, and the absence of SC does not inherently diminish the page's quality or impact. This is why the statement about SC enhancing a webpage but not being mandatory for high ratings accurately reflects its role in web content strategies.
