Google AI Overviews SEO: How Gemini, AI Overviews and AI Mode Pick Sources
Google says there is no special file or markup for AI Overviews or AI Mode: a page must be indexed and eligible for a Search snippet, so the work is ordinary Search hygiene plus passages worth quoting. Google-Extended only governs Gemini training and grounding. Leadee measures Gemini through Google's grounding API, and AI Overviews and AI Mode through DataForSEO, because Google has no API for them.

How does Leadee work with Google AI?
- Uses the official API: Gemini API (Grounding with Google Search)
- Measured through DataForSEO, not a Google API: Google AI Overviews
- Measured through DataForSEO, not a Google API: Google AI Mode
- Data from the site owner (connection or file upload): Search Console "Generative AI features" export (beta)
Can AI engines read and quote your site?
This is Leadee's all-engine AI Visibility Checker. A Google-specific preset is a separate follow-up job, not built yet.
What does Google require for AI Overviews and AI Mode?
Google's own guidance: to be shown as a supporting link in AI Overviews or AI Mode, "a page must be indexed and eligible to be shown in Google Search with a snippet." Google adds that there are "no additional requirements" and no special schema.org markup or AI text file needed, and that indexing and serving are not guaranteed.
The controls are the normal Search ones: robots.txt rules for Googlebot decide crawling, and nosnippet, data-nosnippet, max-snippet or noindex limit what Google shows. Google also counts clicks from AI features inside the Search Console Performance report, under the "Web" search type, not as a separate line.

Does blocking Google-Extended remove a site from AI Overviews?
No. Google-Extended is a robots.txt product token with no user-agent string of its own: Google's existing crawlers do the fetching, and the token only tells Google whether that content may be used to train Gemini models and to ground answers in Gemini Apps and Vertex AI.
Google states that Google-Extended "does not impact a site's inclusion in Google Search nor is it used as a ranking signal". AI Overviews and AI Mode are Search features, so they follow the Googlebot and snippet controls above, not Google-Extended.

How does Leadee measure Google's AI features?
Google offers no API that returns AI Overview or AI Mode answers, so those two numbers come from DataForSEO's SERP API and every report says so. Gemini is the one Google AI surface Leadee queries directly, through Google's official grounding API.
| Google AI surface | How Leadee measures it | Cost and limits |
|---|---|---|
| Gemini with Google Search grounding | Gemini API, official Grounding with Google Search (default model gemini-3.8-flash) | 14 USD per 1,000 grounded requests after 5,000 free per month; no per-request country setting |
| Google AI Mode | DataForSEO SERP API, Google AI Mode results, including the sources each answer cites | 0.0012 USD per question; 8 locations: US, GB, VN, CA, AU, DE, FR, IN |
| AI Overviews | DataForSEO SERP API, Google organic results: whether an AI Overview appears for a query (Brand SERP report) | About 0.0006 USD per query; presence only, not the full answer |
| AI-feature clicks to your site | Your Search Console "Generative AI features" export (beta), uploaded as a file | Your own site only; Google has no API for this report |

What do people ask about Google AI Overviews SEO?
Do I need llms.txt or special schema for AI Overviews?
Google says no: there is no special file, schema.org markup or extra technical requirement for AI Overviews or AI Mode. A page needs to be indexed and eligible for a Search snippet; structured data still helps Google understand the page, the same as for Search.
Does Leadee read AI Overviews straight from Google?
No. Google has no API for AI Overview or AI Mode answers, and Leadee does not scrape Google. AI Overview presence and AI Mode answers come from DataForSEO's SERP API, and each report names that source.
Can I see AI Overview clicks in Search Console?
Google counts them inside the Performance report under the "Web" search type, together with other Search clicks. If your property shows the "Generative AI features" export (beta), you can upload it to Leadee as a file.
Can GEO guarantee results?
No. AI answer engines change their output frequently, and no vendor — including Leadee — can guarantee a ranking or a mention. Leadee publishes confidence intervals on every metric so you can see how much a result can vary run to run.
How does Leadee measure AI visibility?
Leadee runs your prompt set against each AI engine on a weekly to daily schedule, depending on plan, through official vendor APIs (OpenAI, Gemini, Perplexity, Anthropic, DataForSEO) — never by scraping consumer chat interfaces — and reports mention rate, citation rate, average position, share of voice and sentiment with a 95% confidence interval.
