Which combination best improves the quality score of a health information page?

• A. Many images with no citations
• B. High authoritativeness with credible sources
• C. Long page with dense ads
• D. No information about sources

Answer: (B)

Quality health information is earned through clear evidence of expertise and trustworthy sourcing. When a page shows high authoritativeness with credible sources, it signals that knowledgeable authors stand behind the content and that every factual claim is backed by reliable references. This often includes author credentials, clear affiliations, citations to reputable guidelines or peer‑reviewed studies, and up‑to‑date review dates. Such transparency helps readers trust the information and also gives search systems a basis to evaluate the page as credible and reliable.

Other approaches fall short because they don’t provide that verifiable trust. Images without citations may make the page more engaging, but without sources to verify the claims, the information can’t be reliably judged. A long page filled with ads diminishes readability and user experience, which reduces the perceived quality and trust. No information about sources eliminates transparency entirely, making it hard to assess accuracy or origin.

In short, presenting expertise with credible, traceable sources is the strongest indicator of quality for health information, aligning with how search systems evaluate trust, accuracy, and usefulness.
