AI Overview rollout status (where it is live, where it isn't)
Google AI Overview is rolled out across roughly 100+ countries as of mid-2026, having moved from US-only beta (Search Generative Experience or SGE) in 2023 to global general availability through 2024 and 2025. It renders on roughly 25 to 48 percent of eligible queries, with the rate varying by query intent, region, vertical, and account signals. If you're not seeing one for a query, it usually doesn't mean it isn't rolled out for you; it usually means Google decided not to render one for that specific query.
The rollout timeline
Google AI Overview started as Search Generative Experience (SGE) in May 2023, US-only, opt-in via Search Labs. May 2024 saw the rebrand to AI Overview and the general-availability launch in the US, with global rollout following through 2024 and 2025. By mid-2026 the feature is live across 100+ countries including the US, UK, India, Australia, Canada, Japan, Brazil, Mexico, Indonesia, and most of the EU (with the EU rollout staged to align with DMA and DSA compliance).
Notable exclusions: AI Overview is not available in mainland China (Google itself doesn't operate search there) and remains limited in a few jurisdictions with active regulatory review. EU rollout is on, but the feature is more conservative there about queries it renders on, particularly health and finance categories.
Why you might not see one for a specific query
Five common reasons, none of which mean AI Overview isn't 'live for you'. First, the query is navigational or transactional ('facebook login', 'buy iphone case') and Google rarely renders an AI Overview for those. Second, the query is short or ambiguous and the model isn't confident enough to synthesise. Third, the query is in a category where Google is conservative (medical, financial, legal) and the AI Overview rate is lower.
Fourth, you're signed out (signed-in accounts see AI Overviews more often). Fifth, you're using a non-Google search surface (Bing, DuckDuckGo) and looking at a Google syndication that doesn't render the panel. None of these are rollout problems; they're query-eligibility decisions Google makes per request.
Render rates by category
Industry studies in 2026 put the overall render rate at roughly 25 to 48 percent of eligible queries, with material variation by category. Informational and how-to queries trigger most often (often 50%+). Commercial-investigation queries ('best X', 'top X tools', 'X vs Y') trigger at the higher end. Navigational and transactional queries trigger rarely. Health and finance categories trigger at materially lower rates due to Google's caution.
The practical AEO takeaway: building rankings around the actually-AIO-rendering queries matters more than chasing render-rate parity. monitoraeo's industry rankings use buyer-intent queries that empirically trigger AI Overview at high rates for each category.
How to check current rollout state for your country
The fastest empirical check: run 5 to 10 informational queries in your category on google.com from your region, signed in. If 2 to 4 of them render an AI Overview, the feature is live for you and operating at the normal eligible-query rate. If zero render, either you're searching navigational queries, you're in one of the few remaining excluded jurisdictions, or your account is in a Search Labs opt-out state.
Google's official rollout map is maintained in the Search Help articles but lags real availability by weeks. Trade publications and AEO category trackers update faster. For programmatic checks, providers like SearchApi.io / SerpApi / DataForSEO will tell you per-query whether an AI Overview rendered.

Frequently asked
Is AI Overview rolled out in [country]?
If it's a major market (US, UK, EU member, India, Australia, Canada, Japan, Brazil, Mexico, Indonesia, plus most of Latin America and Southeast Asia), almost certainly yes as of mid-2026. The fastest check is to search 5 informational queries on google.com signed in and see if any render an AI Overview. If 2 or more do, you're live.
Why does AI Overview not show up for my searches?
Usually because your queries are navigational, transactional, or in a category Google is conservative about (medical, financial, legal). AI Overview renders on roughly 25 to 48 percent of eligible queries, and a lot of common searches simply aren't eligible. Try a 'best X' or 'how does X work' query and you'll likely see one.
When did AI Overview launch?
It launched in the US in May 2024 (rebranded from Search Generative Experience or SGE, which had been in Search Labs beta since May 2023). Global rollout followed through 2024 and 2025. By mid-2026 it's live in 100+ countries.
Is AI Overview the same everywhere?
No. The model is the same, but the trigger rate and content are tuned per region. EU AI Overviews are more conservative about which queries they render on (especially health and finance, due to DSA/DMA compliance). US AI Overviews render most aggressively. The citation sources also reflect regional content (UK searches cite UK trade pubs more than US ones).
Can I check programmatically whether AI Overview is live in a country?
Yes via SERP API providers (SearchApi.io, SerpApi, DataForSEO) which let you submit a query with a location parameter and tell you whether the response contained an AI Overview. For a region you don't have an IP in, those APIs are the only practical way. The official Google API doesn't expose AI Overview state.
