Why this distinction matters
Not every page in your site is equally at risk from AI Overviews. A dental practice’s “dental implants Tucson” service page (transactional intent) is unlikely to see an AI Overview above it. Its “how long does a dental implant take to heal” content page (informational intent) almost certainly will.
That difference has two practical implications. Pages targeting informational queries face the largest CTR reduction risk: the AI Overview appears above the organic results and answers the query without the user clicking through. Those same pages also have the highest potential gain from GEO optimisation: being cited as a named source in an AI Overview replaces some of the lost click value and builds brand recognition at the moment a buyer is forming their understanding of a topic.
Investing GEO optimisation effort on transactional queries where AI Overviews rarely appear is lower priority. Investing it on informational queries where AI Overviews appear consistently is high priority. The taxonomy below makes those decisions straightforward.
Query types that trigger AI Overviews most consistently
Informational queries are the primary AI Overview trigger category. Within informational queries, five sub-types trigger AI Overviews at the highest rates.
Definition queries ask what something is. “What is a dental implant,” “what is AEO,” “what is a home equity loan,” “what is holistic SEO.” These are among the most consistent AI Overview triggers because they match precisely what AI systems are built to do: provide a direct, synthesised definition.
How-to queries ask how to do something. “How to choose a family dentist,” “how to improve local SEO,” “how to set up a content calendar,” “how to file a small claims court case.” AI Overviews appear on these queries frequently because a step-by-step synthesised answer serves user intent directly.
Comparison queries ask about the difference between two things. “AEO vs SEO,” “memory foam vs latex mattress,” “Shopify vs WooCommerce,” “dental implant vs bridge.” AI Overviews synthesise comparison summaries on these queries at high rates, particularly when the comparison has clear factual dimensions (cost, timeline, suitability for different users).
Best-X-for-Y queries ask for a recommendation for a specific use case. “Best running shoes for flat feet,” “best espresso machine for home barista,” “best accounting software for sole traders,” “best dentist in Tucson for dental anxiety.” These trigger AI Overviews consistently and are a primary GEO citation target for local and ecommerce businesses.
Research and guidance queries ask what to look for, what to expect, or how to evaluate something. “What should I look for in a family dentist,” “what to expect after a dental implant,” “how do I know if I need a root canal,” “what questions should I ask a financial advisor.” These trigger AI Overviews reliably because the AI-synthesised answer is genuinely more useful than a single source.
Query types with moderate AI Overviews trigger rates
Some query types trigger AI Overviews inconsistently, appearing for some queries in the category but not others.
Complex opinion and advice queries sometimes trigger AI Overviews and sometimes do not. “Is it worth getting dental implants,” “should I incorporate my small business,” “is a fixed rate or variable rate better for my mortgage” are in this category. Google’s systems appear to apply more caution on queries where the “right” answer depends heavily on individual circumstances.
Local service queries fall in the moderate range. “Emergency plumber Denver,” “family dentist Tucson accepting new patients,” “employment lawyer Portland OR” sometimes trigger local AI Overviews with business recommendations and sometimes return standard local pack results. The presence of a local AI Overview on these queries is growing but not yet as consistent as for pure informational queries.
Health and finance informational queries are a special case. Google has applied restrictions on YMYL (Your Money or Your Life) queries to limit AI Overviews on health diagnosis and financial advice queries specifically — not because these queries are informational but because the risk of synthesised advice being harmful is higher. Informational health and finance queries that avoid diagnosis or specific advice recommendations (“how long does wisdom tooth extraction recovery take” vs “should I have my wisdom teeth removed”) trigger AI Overviews more consistently.
Query types that rarely trigger AI Overviews
Transactional and commercial queries — where the user’s intent is to buy, book, or get a price — rarely trigger AI Overviews. “Buy dental implants Tucson,” “dental implants cost Tucson,” “book a dental appointment,” “Shopify pricing,” “ergonomic chair under 500.” Google recognises these as queries where a direct transactional result is more useful than an AI-synthesised paragraph.
Navigational and branded queries almost never trigger AI Overviews. “Wayfair sofas,” “Amazon Prime login,” “Riverside Dental Tucson appointment,” “[brand name] return policy.” The user has already decided where they are going. AI Overviews add no value and Google’s systems reflect that.
Direct product and brand searches (“Nike Air Max 270,” “iPhone 15 Pro review from Apple,” “[specific product SKU]”) produce standard product results and review listings rather than AI Overviews.
How to audit your keyword set for AI Overview exposure
Manual testing is the most reliable method. It takes 30 to 60 minutes for a keyword set of 50 queries and produces a clear prioritisation map.
Open Google Search in a browser logged out of any Google account (or in incognito mode) to see results without personalisation. Search each of your top 50 target queries. Note whether an AI Overview appears in the results: log Y or N in a spreadsheet. Record the approximate position of the AI Overview when it appears (above the organic results or somewhere else on the page).
After testing all 50 queries, sort the spreadsheet by AI Overview presence (Y/N) and cross-reference with your keyword traffic volume data. The queries in the upper-left quadrant of your priority matrix — AI Overview present AND high traffic volume — are your highest-priority GEO optimisation targets. The queries in the lower-right quadrant — AI Overview absent AND lower traffic volume — are your lowest GEO priority for now.
Repeat the test quarterly. AI Overview trigger rates shift as Google’s systems evolve, and a query that does not trigger an AI Overview today may do so in six months.
What to do with this information
For queries that consistently trigger AI Overviews, focus GEO investment: restructure content to open with a direct answer in the first paragraph, add FAQPage schema to question-and-answer content on those pages, ensure entity coverage is complete, and test monthly to confirm citation status.
For queries that rarely trigger AI Overviews, focus standard SEO: maintain strong ranking positions, optimise title tags and meta descriptions for CTR, and ensure these pages serve transactional intent cleanly. These pages are not where GEO investment pays off.

Frequently asked questions
Which queries trigger Google AI Overviews?
Google AI Overviews trigger most consistently on informational queries across five sub-types: definition queries (“what is X”), how-to queries (“how do I do X”), comparison queries (“X vs Y”), best-X-for-Y queries (“best mattress for side sleepers”), and research guidance queries (“what should I look for in X”). These trigger AI Overviews at the highest rates because AI-synthesised answers directly serve the informational intent. Transactional queries (“buy X,” “X price”), navigational queries (“[brand] login,” “[brand] sofas”), and direct product searches trigger AI Overviews rarely or not at all.
Do commercial keywords trigger AI Overviews?
Rarely. Commercial and transactional queries, including buy-intent queries, price queries, and direct product searches, trigger AI Overviews far less consistently than informational queries. Google recognises that a transactional result (product listing, price comparison, booking option) serves the user better than an AI-synthesised paragraph for these queries. The practical implication: commercial and conversion-focused pages are less at risk from AI Overviews absorbing clicks, but they also have less to gain from GEO optimisation. Focus GEO investment on informational query pages rather than commercial ones.
Are informational keywords more affected by AI Overviews than transactional keywords?
Yes, substantially. Informational queries trigger AI Overviews at far higher rates than transactional queries. For a site with a mixed keyword portfolio, the pages targeting informational queries (“how to choose,” “what is,” “best X for Y”) face the most significant CTR risk from AI Overviews appearing above the organic results. These same pages also represent the highest GEO opportunity: being cited in an AI Overview for an informational query reaches buyers early in their research process, before they have committed to a product or provider.
How do I find out which of my keywords have AI Overviews?
Test manually: search each of your top 50 target queries in Google Search (in incognito mode to avoid personalisation) and note whether an AI Overview appears. Log the results in a spreadsheet with columns for query, AI Overview present (Y/N), and your monthly traffic volume from Google Search Console. Sort by AI Overview presence and cross-reference with traffic volume to identify which of your high-traffic pages face the highest AI Overviews exposure. Repeat this audit quarterly, since AI Overview trigger rates shift as Google’s systems evolve.
Do local keywords trigger Google AI Overviews?
Sometimes, with increasing frequency. Local service queries (“emergency plumber Denver,” “family dentist Tucson”) fall in the moderate trigger category — AI Overviews appear for some local queries but not all, and the feature is more consistent for some service categories than others. Best-X-for-Y local queries (“best dentist in Tucson for dental anxiety”) trigger AI Overviews more consistently than direct service queries (“dental implants Tucson”). Local businesses should test their priority local queries manually and monitor monthly, since local AI Overview coverage is expanding.
