AiSearchEntityThe image below illustrates how the AI Overview response maps to the Google AI Overview interface:

| UI Element | API Field | Description |
|---|---|---|
| 🔴 Main AI Overview (red bordered area) | text | The AI-generated overview text displayed in the main content area, synthesized from multiple sources. |
| 🟡 Inline Citations (yellow circles within text) | citations | References embedded within the AI Overview (linked numbers). Each citation links to a source URL with title, source name, and favicon. |
| 🔵 Source Panel (right sidebar) | sources | The list of source websites displayed on the right side, including title, source domain, and favicon. |
citations array provides granular source attribution for specific claims within the AI Overview, while sources offers a broader overview of all referenced websites with their metadata.
