A new research report has revealed that YouTube is the most frequently cited website within Google AI Overviews for vitamin and supplement searches.

The prominence of video content within AI Overviews highlights a significant shift in how search algorithms evaluate multimedia resources for health-related inquiries. Google's AI models increasingly favor engaging video platforms when summarizing complex lifestyle and wellness topics for users.
The research also uncovered discrepancies between AI Overviews and standard organic listings. Only 32.4% of pages cited by the AI appeared in the collected organic results, while 67.6% did not. Matching by website domain instead of exact URL elevated the overlap to 52.5%, indicating that AI selections often point to alternative pages on domains already present in organic search.
The comprehensive analysis evaluated 350 AI Overviews and 5,036 citation occurrences across 572 distinct pages and 218 websites, utilizing US English desktop results configured for New York.
