AI Overviews is a summary on top of normal results; AI Mode replaces the results with a conversation. For a small business, the work to appear in each is the same: Google says both need only an indexed page that's eligible for a snippet, with no extra technical requirements. What differs is the outcome. The best study so far found that AI Mode cut clicks to websites by 18.8 percentage points, and a vendor study found AI Mode's local recommendations left out 28.5% of the businesses in the matching Local Pack. So keep your Business Profile current, write pages that answer the questions an assistant gets asked, and measure impressions in Search Console rather than expecting clicks.
This page compares the two features from Google's documentation and the published studies we could find, read between October 31 and November 1, 2026. We haven't run our own experiments on either.
The two side by side
| AI Overviews | AI Mode | |
|---|---|---|
| Where it appears | At the top of an ordinary results page, above the links | Its own search experience; the AI answer is the page |
| When it appears | Only when Google's systems judge it adds something to classic results | Whenever someone chooses AI Mode |
| What Google says it's for | Getting "to the gist of a complicated topic or question more quickly" | Queries "where further exploration, reasoning, or complex comparisons are needed" |
| Follow-up questions | No | Yes, conversational |
| How it builds an answer | May use query fan-out: several related searches across subtopics | May use the same technique |
| To appear as a link | Indexed and snippet-eligible; "no additional technical requirements" | Same |
| Controls | nosnippet, data-nosnippet, max-snippet, noindex | Same |
| In Search Console | Performance report (Web) and the generative AI reports | Same |
The descriptions and requirements come from Google's AI features and your website page (last updated December 10, 2025). The Search Console reports are covered below.
What the click data says
This is where the two features really differ for a business that depends on visits.
AI Overviews. Pew Research tracked the browsing of 900 US adults in March 2025 and reported in July 2025 that people who saw an AI summary clicked a traditional result in 8% of visits, against 15% when no summary appeared. They clicked a link inside the summary in 1% of visits. Google called the study's method "flawed" and its queries "not representative of Search traffic."
AI Mode. Researchers at the University of Pennsylvania and Northeastern University ran a preregistered field experiment in March 2026 with 1,444 US adults enrolled, 1,100 of whom searched during the study, randomly assigning them to normal Google, Google with AI features hidden, or Google with every search sent to AI Mode, for a week. As summarised by Relevant Audience from the arXiv preprint (August 18, 2026):
The authors list real limits: it's a preprint, the sample skewed younger and more educated than the US population, AI Mode was forced rather than chosen, and the test lasted seven days. It's still the only randomised comparison of the two features we found, and both studies point the same way: the more of the page the AI answer takes, the fewer people click through.
What that means in practice: if a customer finds you through AI Mode, they may phone you, visit, or search your name later without ever clicking your link. Your analytics will undercount it. Our Observatory data shows the same gap from the other side: AI assistants sent a median of 0.03% of visits to the small-business sites we measure.
What changes for local results
For a plumber, dentist or restaurant, the question is whether AI Mode recommends the same businesses as the map results. One study says often, but not always.
Local SEO Data, a company that sells local search data, ran 1,120 queries across seven local verticals in 13 US cities in May 2026, each in both AI Mode and the Local Pack, and published the results in a paid press release in June 2026. Treat it as a vendor's study, not independent research. Its main findings:
- 28.5% of Local Pack businesses didn't appear in AI Mode for the same query; overlap was 71.5%, and only 48% among the top three of each.
- 999 businesses appeared only in AI Mode, never in the Local Pack.
- Reviews seemed to matter more in AI Mode for trades: among consumer businesses, AI-Mode-only ones had a 49% higher median review count than Local-Pack-only ones, and for plumbers the median was 546 reviews against 125.
- Phrasing changed everything for some queries. A bare "divorce lawyer" returned no business listings in AI Mode in any of 10 cities; adding "near me" returned listings every time. For lawyers and medical specialists, AI Mode more often answered with general information than with businesses.
- The specific businesses shown changed from day to day, even when the overall pattern held.
Google's own advice for businesses is short: it suggests "checking that your Merchant Center and Business Profile information is up-to-date" (Google). Put together, the practical reading is that your Business Profile and reviews feed both surfaces, and that AI Mode leans on them differently enough that ranking in the map pack doesn't guarantee a mention.
What doesn't change
Most of the advice is identical for both features, which is good news for a small team.
- Eligibility is the same. An indexed page that can show a snippet. No special markup, no AI text files: Google says there are no additional technical requirements, and our llms.txt evidence review covers why that file doesn't help here.
- Controls are the same.
nosnippetornoindexkeeps a page out of both. If you setnosnippetsite-wide by accident, you're out of both. Our AI access checker flags it. - Googlebot does the crawling. Blocking Google-Extended affects training and grounding in other Google systems, not Search; robots.txt rules for Googlebot control Search, including both AI features. Our robots.txt guide explains the difference.
- Reporting is the same place. Both count in Search Console's Performance report under Web, and both appear in the generative AI reports.
What to do about each
| If you are… | AI Overviews | AI Mode |
|---|---|---|
| A local service business | Answer common questions on your service pages (cost, timing, area served) so a summary can cite you | Keep your Business Profile complete and current, keep earning reviews, and check AI Mode with "near me" phrasing in your monthly prompts |
| A professional service (legal, medical) | Clear, factual explainer pages in plain language | Expect more general information and fewer listings for broad queries; make sure your pages answer the specific questions people ask after the first one |
| A shop selling online | Product pages with specifics: price, sizes, stock, delivery | Keep Merchant Center data current, as Google advises |
| Anyone | Measure impressions in Search Console's generative AI reports | Same, and add AI Mode to the assistants in your prompt sheet |
For measuring, Search Console's generative AI performance reports (announced June 2026, available to all sites since August 31, 2026) show impressions by page, country, device and date across AI Overviews, AI Mode and Discover. They don't show clicks, and GA4 can't separate AI Overview or AI Mode clicks from ordinary Google organic traffic. Our guide to tracking AI visibility for free sets out the full monthly routine, including a prompt sheet that covers AI Mode.

Questions people ask
What is the difference between AI Overviews and AI Mode?
AI Overviews is a summary Google adds at the top of some ordinary search results. AI Mode is a separate, conversational search experience where the AI answer is the whole page and you can ask follow-up questions. Google describes AI Mode as for queries that need more exploration, reasoning or comparison.
Do I need to do anything different to appear in AI Mode?
No. Google says a page must be indexed and eligible to show with a snippet to appear in either feature, and that there are no additional technical requirements. The same controls (nosnippet, max-snippet, noindex) apply to both.
Does AI Mode send fewer clicks than AI Overviews?
The best evidence so far says yes. In a preregistered field experiment with 1,100 US adults who searched during the study, published as a preprint in August 2026, forcing searches into AI Mode cut click-through to external websites by 18.8 percentage points compared with normal Google search.
Can I see AI Mode traffic in Search Console?
Yes, as impressions. Search Console's generative AI performance reports, available to all sites since August 31, 2026, cover AI Overviews, AI Mode and AI features in Discover. They don't report clicks, and the same data also counts in the main Performance report.
