Google SGE, AI Overviews, and AI Mode: A Plain-English Glossary for Marketers

15+ years in local marketing; Google Ads certified; Shopify Partner.

You open Google to search for something. The results look different than they did two years ago. There's a big AI-generated answer at the top. Sometimes there's a different kind of AI answer. Sometimes there's a box that looks almost like a chatbot. And somewhere in a marketing meeting, someone throws out "SGE" or "AI Mode" or "AI Overviews" like they're all the same thing.

They're not. And if you're making marketing decisions based on a fuzzy understanding of what these terms actually mean, you're probably spending money in the wrong places.

This article is a glossary, not a strategy guide. I'm going to define these terms clearly, explain how they're different from each other, and tell you what actually matters for your marketing. For the deeper strategy side of things, our complete guide to AI for marketing covers the full picture. Here, I just want to make sure we're all speaking the same language first.

What Google SGE Actually Was (and Why It Matters That It's Past Tense)

Let's start here because this is where most of the confusion lives.

Google SGE stands for Search Generative Experience. It was Google's experimental AI search feature, rolled out in limited access through Google Search Labs starting in 2023. The idea was to put an AI-generated summary at the top of search results, above the regular blue links.

It was a test. A public beta. Not a product launch.

By mid-2024, Google had retired the SGE branding entirely. What replaced it was called AI Overviews, and that's what you're actually seeing in Google search results today if you're in Canada or the US. The technology is related, but "SGE" as a named product is gone.

So when someone in 2026 asks "how do I rank for Google SGE," they're using outdated terminology. The feature they're probably thinking about is AI Overviews. I'll get to that in a second.

Why does this matter? Because if an agency is still pitching you an "SGE strategy" without clarifying that they mean AI Overviews, that's a small flag. Not a dealbreaker, but it tells you something about how current their knowledge actually is.

AI Overviews: What They Are and How They Work

AI Overviews are the AI-generated summaries that appear at the top of certain Google search results. You've seen them. They look like a paragraph or two of synthesized information, sometimes with citations to sources on the right side.

Here's the thing: they don't show up for every search. Google serves AI Overviews most often on informational queries, things like "how does X work" or "what's the difference between X and Y." For commercial queries ("dentist in Regina") or navigational queries ("Unalike Marketing"), they show up far less often.

The citations in AI Overviews are the piece that matters most for your marketing. Google is pulling from pages it considers authoritative and well-structured on the topic. If your page gets cited, you show up in the AI answer even if the user never clicks through to your site. That's a brand impression. It's not nothing.

But here's the honest part: there's no published formula for getting cited. What we know from observation is that pages with clear structure, specific answers, and credible sourcing tend to appear more often. For a full breakdown of how to actually show up in these results, see our guide on ranking in Google AI Overviews.

One thing worth noting for Canadian SMBs: AI Overviews rolled out more slowly in Canada than in the US. As of 2026, they're active in Canadian search, but the query coverage is still narrower than what US users see. So if you're testing this and not seeing AI Overviews on your own searches, that's normal.

AI Mode: The Newest Layer (and the Most Different One)

AI Mode is a separate thing from AI Overviews, and this is where I see the most confusion.

AI Mode is essentially a conversational search experience within Google. Instead of a standard results page with links and an AI summary on top, AI Mode gives you a chat-style interface where you can ask follow-up questions, refine your search, and get longer synthesized answers. Think of it as Google's answer to how people are using ChatGPT for research.

As of 2026, AI Mode is still rolling out. It's available in the US via Search Labs and is being tested more broadly. Canadian availability is limited. So if you're a Canadian SMB trying to "optimise for AI Mode" right now, I'd honestly tell you to put that on the back burner. It's real, it's coming, but it's not where your marketing attention should go today.

What AI Mode does tell us is where Google is heading. The whole search experience is moving toward conversation and synthesis, not just a list of links. That has long-term implications for how you build content and structure your site. Our Google AI Mode breakdown goes into the specifics of what that shift means for Canadian businesses.

How These Three Things Relate to Each Other

Here's a simple way to think about it:

SGE was the experiment. It's retired. You don't need to optimise for it because it no longer exists as a named product.

AI Overviews is the current deployed feature. It's live in Canadian search. It shows up on informational queries. Getting cited in AI Overviews is a real goal worth pursuing.

AI Mode is the future direction. It's a more immersive, conversational search experience. It's coming, but it's not fully here in Canada yet.

They're all related, they all come from the same underlying technology (Google's Gemini models), but they're different surfaces with different behaviours. Treating them as interchangeable will get you bad advice.

The Broader Landscape: Where Google Fits in 2026

I think it's worth zooming out for a second, because Google isn't the only place where AI-generated answers are happening.

ChatGPT, Perplexity, and other AI tools are now being used for product and service research. Per a 2024 Microsoft/Harris Poll study, 71% of Canadian SMBs report actively using AI tools, and a meaningful portion of their customers are doing the same on the research side. When someone asks ChatGPT "who's the best accountant in Saskatoon," they're getting an AI-synthesized answer, not a Google results page.

That's why the broader category of generative engine optimisation matters. GEO is the practice of making your content visible and citable across AI systems, not just Google. AI Overviews is one piece of that. ChatGPT citations are another. Perplexity is another.

If you want to understand how to show up across all of these surfaces, our guide on how to show up in AI search is the right next read.

The point is: Google SGE, AI Overviews, and AI Mode are all Google-specific. But your customers are using multiple AI tools to research purchases. A strategy that only focuses on Google's AI features is leaving visibility on the table.

What This Means for Your Marketing Spend

Here's where I want to be direct, because I think a lot of agencies are going to start pitching "SGE optimisation" or "AI Overviews strategy" as a premium add-on service, and I want you to be able to evaluate those pitches clearly.

First, a worked example. Let's say you're running Google Ads for a professional services firm. Per DataForSEO's Canadian data, the average CPC for "ai seo" in Canada is CA$21.33. If AI Overviews are now showing up above the paid ads for informational queries related to your service, and users are getting their answer without clicking, that changes your click-through rate on both organic and paid results.

The math: if your paid campaign was getting a 5% CTR at CA$21.33 per click, and AI Overviews are now absorbing some of those informational queries before they reach your ad, your effective cost per qualified visit goes up even if your CPC stays the same. You're paying the same price for fewer opportunities.

That's not a reason to panic. It is a reason to look at your query segmentation. Are you bidding on informational queries where AI Overviews are likely to intercept? Or are you focused on high-commercial-intent queries where AI Overviews show up less? That's the adjustment worth making.

Second, I want to name a pattern I've seen repeatedly. Agencies will sometimes conflate "AI Overviews" with "AI SEO" with "GEO" with "SGE" in a pitch, and the result is a strategy that's vague enough to be unfalsifiable. You can't measure whether you're "optimised for SGE" because SGE doesn't exist anymore. If someone is pitching you that, ask them to define their terms and show you what metric they're actually moving.

A Week-by-Week Look at How to Actually Audit Your AI Visibility

If you want to get practical about this, here's how I'd approach it over about three weeks. This isn't a full optimisation project, it's a diagnostic.

Week 1: Map your query landscape. Pull your top 20-30 organic search queries from Google Search Console. For each one, do a manual Google search in an incognito window. Note which ones trigger AI Overviews. Note which ones don't. You're looking for the pattern: are the queries where you rank well also the queries where AI Overviews are showing up and potentially absorbing clicks?

Also note whether your site is cited in any of those AI Overviews. If you're ranking in position 1-3 organically but not cited in the AI Overview above you, that's a content structure issue worth investigating.

Week 2: Check your content against what's being cited. Look at the pages that ARE cited in AI Overviews for your target queries. What do they have in common? Usually: clear question-and-answer structure, specific data points, well-organised headers, and credible sourcing. Compare that to your own pages. Where are the gaps?

This is also a good time to check whether your site has proper schema markup. Our guide on schema markup for AI search explains what actually matters here.

Week 3: Check your visibility beyond Google. Search for your business name and your primary service category in ChatGPT and Perplexity. Are you showing up? Are competitors showing up instead? This is your baseline for AI citation tracking. For a structured way to track this ongoing, see our breakdown of AI search visibility.

By the end of week three, you should have a clear picture of where you're visible in AI-generated answers and where you're not. That's the starting point for any real strategy.

Three Takeaways to Finish

1. SGE is retired. Update your vocabulary. If you or your agency are still talking about "ranking for SGE," that terminology is outdated. The current Google AI feature is AI Overviews. Knowing the difference matters when you're evaluating a pitch or a strategy.

2. AI Overviews and AI Mode are different surfaces with different timelines. AI Overviews is live and relevant in Canada right now. AI Mode is still rolling out and not yet a priority for most Canadian SMBs. Don't let an agency charge you a premium to optimise for something that isn't fully deployed here yet.

3. Google is only one piece of the AI visibility picture. Your customers are researching using ChatGPT, Perplexity, and other AI tools alongside Google. A strategy that only addresses Google's AI features is incomplete. The answer engine optimisation guide and our GEO step-by-step cover the rest of the landscape.
