Reviews can be classified as Main Content or Supplementary Content depending on the page. Which option reflects this?

• A. They are always Main Content
• B. They are always Supplementary Content
• C. They can be Main Content or Supplementary Content depending on the page
• D. They are never content

Answer: (C)

The key idea is that whether a review is main content or supplementary depends on what the page is trying to accomplish. On a product detail page, users come to decide whether to buy, so reviews provide essential, decision-driving information and act as the core content. On a different type of page, like a general article or a category hub, reviews might appear as a supporting feature—helpful context or social proof—but they aren’t the primary purpose of the page, so they function as supplementary content. That’s why the best answer says reviews can be either main or supplementary depending on the page. They aren’t inherently always main, nor inherently never content, and they aren’t always solely supplementary; their role shifts with page intent.
