The Gemini Grounding Tool identifies which URLs and specific sentences Google's AI extracts to ground its answers, helping optimize content for AI search.
In the era of AI search, ranking number one on Google is no longer enough. You can top the search results and still be completely invisible to artificial intelligence.
That is because search engines like Google's Gemini do not just link to your page anymore. They perform live searches, retrieve top pages, and extract specific sentences to ground their answers in real facts. These extracted sentences are called grounding chunks, and they are the new currency of search visibility.
In traditional search, users click your link and read your page. In AI search, the AI is the reader. It selectively pulls sentences, synthesizes an answer, and presents it to the user. If your content is not structured for this, competitors with more grounding-friendly text will win the AI's favor, even if you rank higher.
To see what the AI actually reads, you can use the Grounding Snippet Tool. By entering a query and a location, this tool reveals exactly which websites the AI uses and the precise sentences it extracts.
To optimize for this new reality, you need to write clear, factual, and self-contained statements. Front-load your most important information so the AI can easily extract it.
Ranking is still necessary, but it is no longer sufficient. To succeed today, your content must be structured to feed the AI the exact answers it is looking for.
You can rank #1 and still be invisible to AI search.
That’s the uncomfortable truth of the AI Mode era. Google’s AI doesn’t just look at your page, it extracts specific sentences, evaluates them against the query, and decides whether your content deserves to ground its answer. The rest of your carefully crafted copy?

The Gemini Grounding Tool reveals:
Enter a query. Optionally add a location. See what the AI actually reads.
That’s it. Now you know which content is working in AI search—and which isn’t.
When Gemini answers a query, it doesn’t hallucinate from training data alone. It performs live Google searches, retrieves pages, and extracts specific text segments to “ground” its response in real sources. These grounding chunks are the atomic unit of AI search visibility.
Think of it like this:
Traditional Search:Query → Ranked URLs → User clicks → User reads pageThe critical difference: the AI is now the reader. And it’s a very selective reader.
You might rank position 1 for a query and still have zero presence in the AI answer. Why?
The tool exposes this gap.
Once you see what gets grounded, you can:
Run your competitors’ branded queries. See what sentences Gemini extracts from their pages. Understand what content structure is winning in your vertical.
The tool uses Gemini’s google_search grounding tool to perform live searches, the same infrastructure that powers AI Mode. Results reflect real-time grounding behaviour, not cached or estimated data.
Location parameter affects localisation. A query from “Sydney, Australia” will return different sources than the same query from “New York, USA.”
AI search is rewriting the rules of visibility. Ranking is necessary but no longer sufficient. Your content needs to be grounding-friendly, structured so the AI extracts the right sentences and presents them prominently. This tool shows you what’s actually happening.
Thank you Kevin!
Wow Dan. Thanks for sharing your Tool to the public. What is your workflow after the results?
Honestly still working on that part.
