If you remember Google's Search Generative Experience, or SGE, the experiment has changed considerably. SGE was the test. AI Overviews and AI Mode are the products businesses need to understand now.
AI Overviews can answer a question directly inside a normal Google results page. AI Mode goes further, letting people ask longer questions, compare options and continue with follow-up questions.
This is no longer a small Search Labs experiment. Google says AI Overviews now reach more than 2.5 billion monthly active users, while AI Mode has passed 1 billion monthly users. Google's 2026 update on AI Search
For businesses, the important question is no longer whether AI will change Google Search.
It already has. The question is what that means for rankings, clicks and your SEO strategy.
What Happened to Google's Search Generative Experience (SGE)?
The short version: SGE did not disappear. It evolved.
Google introduced Search Generative Experience in 2023 through Search Labs. It was an experimental version of Google Search that could generate an AI response above the traditional results.
The name did not last.
2023: Search Generative Experience
SGE was Google's early public test of generative AI inside Search.
Users could ask questions and receive an AI-generated response supported by information from the web.
At the time, the feature was experimental and separate from the normal Google experience.
2024: AI Overviews
Google moved the concept into its main Search product and began calling the generated summaries AI Overviews.
Instead of being something users had to deliberately test in Labs, AI-generated answers started appearing directly within normal search results when Google's systems believed they would help.
2025: AI Mode
Google then introduced AI Mode for searches that require more exploration, reasoning or comparison.
AI Mode made Search more conversational. Instead of completing one search, users could ask a detailed question and continue refining it through follow-ups.
Google described AI Mode as particularly useful for questions that may previously have required several separate searches. Google's introduction to AI Mode
2026: AI Search Became a Major Part of Google
By 2026, AI Overviews and AI Mode were no longer niche features.
Google says:
AI Overviews have more than 2.5 billion monthly active users
AI Mode has more than 1 billion monthly active users
AI Mode searches are significantly longer and more conversational than traditional searches
Google also introduced dedicated Search Console reporting for generative AI visibility in 2026. So if you still see people talking about "SGE SEO," they are generally talking about what has since become AI Overviews and AI Mode.
What Are Google AI Overviews?
AI Overviews are AI-generated responses that can appear within a normal Google search results page.
They are designed to give someone a quick understanding of a topic while still providing links to supporting websites.
Google does not display an AI Overview for every search. Its systems decide when an AI-generated response would add something useful beyond the standard search results. Google Search Central's AI features documentation
For example, someone searching:
"What size air conditioner do I need for a 2,000 sq ft house in Ontario?"
could receive an AI Overview explaining the factors involved, followed by supporting sources and the normal organic results.
A simple search such as:
"CodeMasters Hamilton"
may not need an AI-generated explanation at all.
That distinction matters.
AI Overviews are especially relevant to searches where people are trying to understand, research, compare or solve something.
Google has also continued adding ways for users to reach original sources. In 2026, it expanded features such as inline links, website previews and Preferred Sources within its AI Search experiences. Google's 2026 update on links and original sources
What Is Google AI Mode?
AI Mode is a deeper, more conversational version of Google Search.
Instead of displaying one AI-generated summary within a traditional results page, AI Mode is built around an ongoing AI response.
A user could ask:
"Compare a heat pump and a gas furnace for a 2,000 sq ft home in Hamilton. Include operating cost, installation cost and how each performs below -15°C."
Then follow with:
"What if the house was built in 1985?"
Then:
"Which option would make more sense if I plan to move in five years?"
That is a very different search journey from typing three or four isolated keywords into Google.
Google says AI Mode is particularly suited to complex comparisons, reasoning and questions that would previously have required several searches. Google Search Central's explanation of AI Mode
AI Overviews vs. AI Mode
AI Overviews | AI Mode | |
Appears inside normal Search | Yes | Separate AI-focused experience |
Main purpose | Quick synthesis | Deeper research and exploration |
Follow-up questions | Increasingly integrated | Core part of the experience |
Links to websites | Yes | Yes |
Appears for every search | No | User and query dependent |
Best suited to | Questions and explanations | Complex questions, comparisons and research |
They are related, but they are not the same thing.
Google also says the two features can use different models and techniques, so the sources shown in an AI Overview may not be the same sources shown in AI Mode. Google's technical guidance for AI Search
How Google's AI Search Finds Information
One of the more important changes is something Google calls query fan-out.
This matters for SEO because Google's AI systems may research a question differently from a traditional search.
What Is Query Fan-Out?
With a traditional Google search, you might think of the process as:
Search → results
AI Search can be more complicated.
Google says AI Overviews and AI Mode may issue multiple related searches across different subtopics and data sources while building a response.
Imagine someone asks:
"What is the best commercial lighting retrofit option for a 50,000 sq ft warehouse in Ontario?"
Google could potentially break that into related searches around:
warehouse LED fixtures
high-bay lighting
Ontario lighting incentives
lighting energy savings
retrofit payback periods
lighting levels for warehouses
The AI response can then draw supporting information from pages discovered across those related searches.
Google calls this query fan-out. Read Google's explanation of query fan-out
What Query Fan-Out Means for SEO
This creates an important difference between traditional rankings and AI visibility.
A page does not necessarily have to be the number-one result for the exact words the user typed to potentially become a supporting source.
Google may discover it while researching one of the related questions.
That does not mean rankings no longer matter.
It means good SEO increasingly needs to demonstrate depth around a subject instead of creating one page for one exact keyword.
A useful service page can explain the commercial offer.
Supporting articles can answer the questions around it. Case studies can prove the experience. Tools, original data and examples can provide information that competing pages do not have. Good internal linking then helps Google understand how those pieces fit together.
How Do AI Overviews Affect Organic Traffic?
This is where the discussion gets more complicated.
Google and independent researchers do not tell exactly the same story.
Google's Position: Search Traffic Remains Strong
Google says overall organic click volume from Search has remained relatively stable.
It also says clicks originating from AI-enhanced search results can be higher quality, meaning users who do click may be more likely to remain on the destination website.
Google's argument is that AI features also encourage people to perform more searches and ask questions they could not easily ask before. Google's data on AI Search and website clicks
That is worth considering.
But it is only one side of the data.
Independent Research Shows Fewer Clicks on Some AI Searches
A 2025 Pew Research Center study examined browsing behaviour from 900 U.S. adults.
When an AI summary appeared:
users clicked a traditional search result on 8% of visits
when no AI summary appeared, they clicked a traditional result on 15% of visits
users clicked a source directly inside an AI summary on only about 1% of visits
Pew also found users were more likely to end their browsing session after a search that contained an AI summary. Read the Pew Research Center study
Ahrefs found a similar direction in a much larger keyword study.
Its February 2026 analysis compared 300,000 keywords and found that the presence of an AI Overview correlated with a roughly 58% lower click-through rate for the number-one organic result than its model predicted without an AI Overview. Read the Ahrefs AI Overview CTR study
That is correlation, not proof that every AI Overview cuts traffic by 58%.
But combined with the Pew data, the direction is difficult to ignore.
The Practical SEO Takeaway
Visibility and clicks are becoming less tightly connected.
A page can:
rank organically
appear as an AI source
generate impressions
without necessarily receiving the same number of clicks that a similar ranking produced several years ago.
For businesses, this makes vanity metrics less useful.
You still want visibility.
But the better questions are:
Are qualified users reaching the site?
Are branded searches growing?
Are calls and forms increasing?
Which pages are appearing in AI Search?
Which topics are producing actual business?
This is why SEO reporting increasingly needs to connect Search Console with conversions in GA4 rather than stopping at rankings and impressions.
How to Optimize for Google AI Overviews and AI Mode
There is a lot of noise around "AI SEO," "AEO" and "GEO."
Google's own guidance is much less exotic.
There is no secret AI Overview optimization method.
Google says the same foundational SEO practices used for traditional Search remain relevant to AI Overviews and AI Mode. It specifically says there are no additional technical requirements for appearing in these features. Google's AI Search guidance for website owners
That does not mean nothing has changed.
It means the work still starts with good SEO.
Make Important Pages Crawlable and Indexable
This comes first.
Google says a page must be indexed and eligible to appear in normal Search with a snippet before it can appear as a supporting link in AI Overviews or AI Mode.
Check:
robots.txt
noindex directives
canonical tags
crawl accessibility
internal links
sitemap coverage
rendering problems
There is no point discussing AI citations if Google cannot reliably crawl the page.
Publish Information That Adds Something
This is probably the biggest content opportunity.
Google's newer AI Search guidance emphasizes valuable, unique, non-commodity content. Google's 2026 guidance for generative AI Search
In plain English: publishing another rewritten version of information already available on 200 websites gives Google very little reason to choose yours.
Useful additions could include:
firsthand experience
real project examples
original photos
testing
case studies
proprietary data
calculators
templates
detailed comparisons
expert commentary
current local information
Suppose 30 plumbing websites all publish an article called "Why Is My Water Bill High?"
The page that includes real causes, pictures of common failures, local water-rate context, a diagnostic checklist and a calculator has much more to contribute than the page that simply rewrites the same seven generic tips.
The objective is not to make every article longer.
It is to make it harder to replace.
Structure Pages So the Answer Is Easy to Find
Do not bury useful information under a 600-word introduction.
Use descriptive headings.
Answer the question.
Then explain it.
Useful page elements include:
clear H2 and H3 headings
short paragraphs
comparison tables
steps
examples
concise definitions
supporting evidence
FAQs when they genuinely help
This is good for people first.
It also makes individual parts of the page easier for search systems to understand.
Build Strong Internal Links
Google specifically includes internal linking among its recommendations for sites appearing in AI Search. Google's AI Search SEO best practices
Internal links help establish relationships between your pages.
For example:
Commercial lighting → lighting audit → incentives → warehouse lighting → case study
is much more useful than publishing five isolated articles that Google has to piece together itself.
Your most important service pages should also receive relevant internal links from supporting content. You can see the broader approach we use for search visibility on our SEO services in Hamilton page.
Use Structured Data, but Don't Expect Magic
Schema still matters.
It can help search engines understand things such as:
your organization
local business information
products
services
articles
events
But there is an important distinction.
There is no special AI Overview schema.
Google explicitly says you do not need new AI markup or special schema.org structured data to appear in AI Overviews or AI Mode.
Your structured data should simply be accurate and match what users can see on the page. Google's structured data guidance for AI features
Use Images and Video When They Add Real Value
Google specifically recommends supporting useful text with high-quality images and video when appropriate.
For a service business, that could mean:
original project photos
before-and-after examples
diagrams
screenshots
process videos
product demonstrations
Do not add stock images just to make a page longer.
Visuals should help someone understand or verify something.
Keep Business and Entity Information Accurate
For local businesses, your website is only one source Google can use to understand the company.
Google recommends keeping Google Business Profile information current as part of its AI Search guidance. Google's AI Search recommendations for businesses
Make sure important facts agree across your web presence:
business name
services
service areas
contact information
location
opening hours
organization details
This already matters for local SEO in Hamilton. AI Search gives businesses another reason to keep those signals clean.
Can You Track AI Overviews and AI Mode in Search Console?
Yes.
And this changed substantially in 2026.
Previously, traffic from AI Overviews and AI Mode was largely folded into the normal Web search type in Google Search Console.
That made it difficult to see how often a website was actually appearing inside Google's generative AI features.
Google changed that in June 2026.
Search Console Now Has Generative AI Visibility Reports
Google launched dedicated Search Generative AI performance reports in Search Console.
As of August 31, 2026, Google says the reports are available to websites worldwide. Google's Search Console AI reporting announcement
The reports currently show:
Impressions: how often your URLs appeared in Google's generative AI features
Pages: which URLs appeared
Countries: where that visibility occurred
Devices: device data for Search
Dates: visibility over time
That is a major improvement.
Instead of guessing whether your content is appearing in AI Search, you can now start measuring it directly.
What the New Report Does Not Tell You
It is still not a complete AI attribution system.
Google's announcement focuses mainly on visibility and impressions, not a clean report showing every AI query, citation and resulting conversion.
So businesses should combine it with:
normal Search Console performance
GA4
lead tracking
phone calls
form submissions
CRM data
A page receiving thousands of AI impressions but producing no business outcome should not automatically be considered a success.
Google Also Added an AI Search Opt-Out
Google has also introduced a Search Console control that lets website owners choose whether their content can appear in and help ground generative AI Search features.
Google says opting out removes the site from those generative Search experiences and therefore also removes the traffic and impressions that could come from them. Read Google's guidance on AI Search controls
For most businesses actively trying to earn search visibility, opting out would need a very clear reason.
Common Myths About AI Search SEO
A new search feature inevitably creates new SEO myths.
Several are already widespread.
Myth: You Need Special AI Schema
False.
Google explicitly says there is no special schema.org markup required for AI Overviews or AI Mode.
Use relevant structured data correctly.
Do not invent an "AI schema" layer because someone sold it as a ranking hack.
Myth: You Need an llms.txt File to Appear in Google AI Search
For Google AI Overviews and AI Mode, no.
Google specifically says sites do not need new machine-readable files or AI text files to appear in these Search features. See Google's AI Search requirements
That does not mean every AI platform treats every file the same way.
It means you should not present llms.txt as a requirement for appearing in Google's AI results.
Myth: Traditional SEO No Longer Matters
Also false.
Google still needs to crawl, index and understand your pages.
Its own guidance says foundational SEO best practices continue to apply to AI Overviews and AI Mode.
Technical SEO matters.
Internal links matter.
Useful content matters.
Page experience matters.
Structured data can still matter.
Business information still matters.
What has changed is the number of search experiences where that work can surface.
Myth: Ranking #1 Guarantees an AI Citation
It does not.
Google says AI Overviews and AI Mode can use different systems and query fan-out to find supporting information. A top organic result can appear in the AI response.
Another page may be selected instead. The set of sources may also change between AI Overviews and AI Mode. Google's explanation of how AI Search selects supporting pages
Traditional rankings are still useful. They simply do not give you a guaranteed AI citation.
Myth: AI Search Means Every Article Needs to Be Longer
No.
An 800-word page that answers the question clearly, includes original evidence and covers the important details can be better than a 3,500-word article filled with repetition.
Depth and length are not the same thing. The goal should be to publish the amount of information needed to genuinely solve the searcher's problem.
Does Traditional SEO Still Matter in 2026?
Yes.
But the target is broader than getting one blue link into position one.
A strong SEO strategy can now support visibility across:
traditional organic results
Google Maps
AI Overviews
AI Mode
images
video
branded searches
other Google search features
The fundamentals have not disappeared. What is changing is how people discover information and whether every search produces a click.
What Has Not Changed
Google still needs to:
discover your page
crawl it
understand it
determine whether it is useful and trustworthy
connect it with relevant searches
That is SEO.
What Has Changed
Businesses need to pay more attention to what happens beyond rankings.
A good SEO program should increasingly ask:
Are our important topics visible?
Are our pages being used in AI Search?
Are people searching for our brand?
Are the right visitors reaching commercial pages?
Are calls, forms and sales increasing?
Are we publishing anything competitors cannot easily reproduce?
This is also why SEO should not operate in isolation.
Website structure, content, conversion tracking, paid search and brand visibility increasingly overlap.
Our Hamilton digital marketing approach is built around connecting those pieces rather than treating every channel as a separate project.

Frequently Asked Questions About Google AI Overviews and AI Mode
What Happened to Google's Search Generative Experience?
Google's Search Generative Experience, or SGE, was the experimental generative-search product Google launched through Search Labs in 2023.
The concept evolved into AI Overviews, which became part of normal Google Search, followed by the introduction of the more conversational AI Mode.
SGE is therefore best understood as the predecessor to Google's current AI Search features.
Are AI Overviews the Same as SGE?
Not exactly.
AI Overviews grew out of Google's SGE experiments, but the product, presentation and underlying systems continued to change after the experimental period.
If you are optimizing a website today, AI Overviews and AI Mode are the current terms that matter.
What Is the Difference Between AI Overviews and AI Mode?
AI Overviews appear within traditional Google search results and provide a generated summary with supporting links.
AI Mode provides a deeper conversational search experience built around longer questions, comparisons, reasoning and follow-up questions.
Google says the two experiences may use different models and may display different supporting sources.
Can My Website Appear in Google AI Overviews?
Yes.
Google says pages can appear as supporting links in AI Overviews and AI Mode if they are indexed and eligible to appear normally in Google Search.
There is no separate application process.
There is also no guarantee that an eligible page will be selected.
Do I Need Special Schema to Rank in AI Overviews?
No.
Google explicitly says no special schema.org structured data is required for AI Overviews or AI Mode.
Continue using relevant structured data where it accurately describes the visible page.
Can I See My AI Overview Visibility in Google Search Console?
Yes.
Google's dedicated generative AI performance reports now show information including impressions, pages, countries, devices and dates.
Google says the reports completed their worldwide rollout on August 31, 2026.
The Takeaway
Google's Search Generative Experience was only the beginning. AI Overviews and AI Mode are now part of how people search, compare options and research more complex questions. That changes the search journey, and in some cases it can reduce the number of clicks going to traditional organic results.
That does not make SEO less important. It makes weak SEO less useful. Websites still need to be crawlable, technically sound and easy for Google to understand. Businesses still need strong service pages, useful supporting content, clear internal links, accurate business information and real evidence of expertise.
The bigger shift is in what businesses should measure. Rankings and impressions still matter, but they should be connected to AI visibility, qualified traffic, leads and revenue. A page appearing in more places across Google is only valuable if that visibility supports the business.
There is also no special shortcut for AI Search. The strongest strategy is still to publish information that is genuinely useful, specific and difficult for competitors to reproduce. That could mean firsthand experience, original data, case studies, tools, expert explanations or content that answers a customer's question better than what is already available.
