Why is ad disclosure important in quality evaluation?

• A. It helps users distinguish ads from organic results and improves transparency.
• B. It has no impact on user perception.
• C. It reduces trust in the results.
• D. It increases page load time.

Answer: (A)

Ad disclosure matters in quality evaluation because it communicates which results are paid placements and which are organic rankings based on relevance. This transparency lets users understand the context of each result, so they can judge its usefulness without being misled into thinking every item is an organic outcome. When ads are clearly labeled, the user experience feels more honest and trustworthy, since sponsorship is openly acknowledged. The other ideas don’t fit because labeling ads actually influences perception in a positive way, does not inherently reduce trust, and doesn’t meaningfully affect page load time in typical scenarios.
