Gemini
Google's Gemini app (and the embedded Gemini features across Google's product surface) is grounded against Google's search index when the conversation calls for current information. Distinct from Google AI Overviews: Gemini is the conversational interface, AI Overviews is the SERP-integrated answer block. Both consume Google's grounding infrastructure but surface citations differently.
Grounding model
Native integration with Google's search index: the same crawl and ranking signals that power Google Search feed Gemini grounding. Grounding is on-demand based on the model's judgment of the query. Source attribution surfaces as a 'sources used' panel.
Citation style
Sources are listed as expandable chips beneath the answer with title, domain, and snippet. Less prominent than Perplexity but more visible than Claude's side panel. Click-through opens the source in a new tab.
What it rewards
- Strong traditional SEO signals (page authority, backlinks, structured data) that drive Google ranking also drive Gemini grounding
- Explicit Schema.org markup (Article, FAQ, HowTo) the same way Google SERP features rely on it
- Recent dates and explicit dating in the page body
- Fast page performance and mobile-friendly design (Core Web Vitals signals carry over)
What it penalizes
- Pages blocked from Google's index (Gemini cannot ground against what Google cannot crawl)
- Thin or duplicate content that Google's quality systems devalue
- Pages with poor mobile experience or Core Web Vitals failures
