Google’s AI Overviews (AIO) — A Complete Guide for Search Marketers

Did you come looking for answers to why your clicks are dropping while your rankings are holding steady?

You’re not imagining it, and you’re not alone.

I’ve been in search since the mid-90s, and I’ll be straight with you: most Google updates rattled the industry and left the fundamentals standing. This one’s different. Not just because the algorithm changed — it always does — but because user behavior changed with it. That’s not something you fix with a title tag.

Google’s AI Overviews are now delivering answers directly on the results page, which means your best-ranking pages are being read, summarized, and skipped — without a single click reaching you. I’m watching it happen across client accounts right now.

This guide covers what AI Overviews actually are, why they’re hitting some content harder than others, and what to do about it — without burning down what’s already working.

Key Takeaways

AI Overviews are changing behavior, not just rankings.
Users are getting answers directly in search, which means fewer clicks even when your rankings stay the same.
Visibility and traffic are no longer the same thing.
You can show up in search and still lose clicks. Success now includes being part of the answer, not just earning the visit.
Informational content is the most affected.
“How,” “why,” and multi-step queries are where AI Overviews appear most often, making them the first place many brands feel the impact.
Authority and clarity matter more than ever.
Content that is well-structured, trustworthy, and covers topics in depth appears more likely to be used in AI-generated summaries.
Traditional SEO still matters, but the goal is shifting.
It’s no longer just about ranking pages. It’s about becoming a reliable source that search engines can draw from.
You need to rethink how you measure success.
Rankings alone don’t tell the full story anymore. Visibility, brand presence, and contribution to the search experience matter just as much.
This isn’t the end of SEO. It’s a shift in how it works.
The fundamentals still apply. The difference is how they show up in a search environment that now includes AI-generated answers.

What Are Google AI Overviews (AIO)?

AI Overviews are AI-generated summaries that appear at the top of certain Google search results. Instead of presenting a list of links, Google builds an answer by pulling from multiple sources.

Where featured snippets pulled from a single page, AI Overviews combine several.

You’ll usually see a short explanation — sometimes broken into steps or bullets — alongside a few cited links. In many cases, the summary gives users enough that they don’t need to click further.

This is what gets people uncomfortable; Google is moving from being a directory to now serving up answers directly, sometimes, skipping you in the process entirely.

Sure you’ve seen this play out before. For example, a student searching “how does compound interest work” used to land on Investopedia or a personal finance blog.

Now, Google will give this user a multi-step explanation right at the top of the results page, including the formula. The student sees no reason to browse further — they’ve gotten their answer. The publisher? Nothing.

Why AI Overviews Change Search (Not Just an Update)

In the past, updates only affected rankings, but not this time. AI Overviews are changing search behavior entirely.

Where organic results used to be the starting point of search, it now feels like it’s being “ghosted” — available, but users eliminate it from their search process.

A user searches, scans through the AI-generated summaries, and moves on.

For businesses who are used to celebrating when the rankings and traffic go up, this new reality is tough to deal with. Now, the numbers don’t make sense and aren’t always moving together anymore.

It also raises the bar for content. If a topic can be summarized in a few lines, users have less reason to click unless your page offers something deeper.

A research from Pew Research Center backs this up with evidence that’s impossible to deny.

They tracked 68,000 real search queries and found something kind of depressing for publishers: users only click on results 8% of the time when AI summaries appear. Compared to 15% without them (AI summaries), it shows a 47% reduction.

This goes to show that this update is not just a dip that’ll recover but a deep behavioral change being observed in searchers.

But, you know what sent the search world into spiral the most?

Hubspot’s massive organic visit decline.

If you know anything about search, you’d know Hubspot has one of the strongest hold on SERP real estate. So, when their monthly organic visits fell from 13.5 million in November 2024 to less than 7 million by December 2024, then, you know to pay attention.

But, don’t think it’s all gloom and doom. I’m just painting you a full picture of what we’re dealing with so you’re better equipped to handle the new search landscape.

When and Where AIO Appears in Search Results

AI Overviews don’t appear on every query, but they show up often enough to matter, especially for informational content.

Query Types That Trigger AIO

AIO is most common for:

Informational queries Example: “how does compound interest work”
Multi-step or layered questions Example: “how to start a podcast and make money”
“How” and “why” queries that require explanation

They’re also starting to appear in commercial searches, where Google summarizes options before showing product or service pages.

Where they appear less often, at least for now:

Clear transactional queries
Branded searches

Not every keyword is equally affected. Informational content tends to feel it first.

AI Overviews often appear above all organic listings. Even if your ranking hasn’t changed, your effective visibility has.

One thing to note is that the coverage by AIO is not static. When tracked in January 2025, 91.3% of the queries that triggered AI Overview were informational. Fast forward to October, that number was down to 57.1% because commercial and transactional queries started appearing more frequently.

This number continues to grow year over year, and we’re now seeing that 48% of all tracked search queries trigger AIO.

Sometimes, throwing percentages around may not make it seem as real to you because numbers don’t really mean anything unless you see it in practice, right?

Well, to put it in perspective, even if you rank #1, users still have to scroll longer to get to you.

A study by Advanced Web Ranking across 8,000 keywords shows us that AI Overviews take up a lot of space — averaging 169 words and 7 links. And because they take up that much space, it pushes down the regular search results way down the page.

On a standard monitor, that #1 organic result now appears so far down that it’s “below the fold” (the part of the page you can’t see without scrolling). In essence, even if you’re crushing it SEO-wise, users need to first get past the AI bit to get to you.

How Google Builds an AI Overview (The Missing Layer)

Google hasn’t published a full breakdown of how AI Overviews are created, but the process can be understood in rough terms.

Step 1 – Query Understanding

Google interprets the intent behind the search — whether the user wants an explanation, a process, a comparison, or something more layered.

Step 2 – Source Retrieval

Google appears to draw from a range of relevant documents, which often includes high-ranking pages.

Step 3 – Content Evaluation

From that pool, content that is relevant, clearly written, and from credible sources tends to be favored.

Step 4 – Synthesis

Information from multiple sources is combined into a single response. This process compresses content, which can strip out nuance.

Step 5 – Citation Selection

Some sources are cited in the overview; others may be used without visible credit.

That distinction matters. Your content can influence an overview without generating a click or visible attribution.

Google guards their secrets jealously, so don’t take this as a formulaic method, but as an informed observation. Things change pretty fast in this industry, too, so this will most likely keep changing.

Google’s secrecy doesn’t stop the industry from trying to crack the code, though, because Ahrefs finds that 76% of AI Overview citations come from pages that already rank in Google’s Top 10. Special preference is often given to those in the top 3 spots.

However, ranking high alone doesn’t mean that you’ll get picked. These AI Overviews are so volatile that they don’t return the same citations 70% of the time — even when you search for the same query. It swaps out 45.5% of the links for new ones with the same query.

So, this new system isn’t a set-and-forget one; it’s almost like a raffle draw still heavily influenced by fundamental and traditional SEO.

What Makes Content “AIO-Eligible”?

There’s no guaranteed path into AI Overviews, but patterns are emerging.

Core Signals

Topical authority — Sites that consistently cover a subject in depth appear more likely to be included
Clarity — Content that explains ideas simply is easier to extract
Consistency — Multiple pages reinforcing a topic strengthen credibility
Trust — Strong signals around expertise and accuracy matter more than ever

Content Formats That Perform Best

Direct answers to specific questions
Step-by-step explanations
Clearly structured sections
Content that covers a topic from multiple angles

Think about extractability.

If your content is difficult to scan or buried in long, unfocused sections, it becomes harder for Google to use. Structured, precise content is easier for these systems to work with.

Businesses always want to know why they should even bother anymore, especially when it seems like Google is taking away clicks. I’ve answered this question many times when my clients feel defeated and confused — I always tell them that being cited matters much more than just the inclusion.

When a site is cited in AI Overviews, the odds are in their favor. They get to enjoy a 35% higher organic click through rate and 91% higher paid click-through rate!

So, getting AI citations isn’t a vanity metric, but one that has real measurable impact on both organic and paid performance.

To get these clicks, you can’t just parrot every other site out there. Preferential treatment is often given to webpages with three or more data tables — they get 25.7% more AI citations!

You’re also more likely to get a seat at the table if you publish proprietary data. This means your own numbers, your clients results, etc. AI might be able to summarize this, but people would have to click on your website to get the full lowdown.

This is a way to structurally put yourself at an advantage.

Is AIO Replacing Traditional Search Results?

Not entirely. What we’re seeing is a layered results page.

At the top: the AI-generated answer. Below that, you may see People Also Ask. Traditional organic listings still exist further down.

All of these layers can appear together. The difference is that attention concentrates near the top.

This doesn’t kill organic search, but it changes how users interact with it. Some stop at the overview. Others continue if they need more detail or context.

When you look at the numbers, it looks like writing informational content is losing its appeal because zero-click searches jumped from 56% in May 2024 to 69% in May 2025. On mobile, the number is even higher — 83%. Which means you’re essentially competing dor 17% of the available clicks.

However, a look at the Daily Mail tells us a hopeful story. Yes, they also reported as much as an 80-90% drop in CTR in queries where AIO appears, but, over 60% of their traffic is direct and over 60% of its organic search is branded.

Know what this teaches us?

That brands with direct and branded search are better protected from the zero-click reality than those that rely on generic informational queries.

How AIO Impacts SEO Strategy

Now, it’s time to face reality. AIO is here to stay and is already causing a major shake-up, especially for sites that heavily rely on informational traffic. It’s time to go back to the drawing board, pull from what we know so far, and strategize effectively.

What’s Losing Value

Thin content that repeats widely available information
Pages built to capture clicks without real depth
Rankings without supporting authority

Content strategies built around high-volume, low-depth topics are starting to show their limits.

What’s Gaining Value

Strong topical authority across related content
Clear, structured explanations
Content that actually helps the reader understand something

One of the bigger shifts: visibility and traffic are no longer as tightly connected as they used to be. Being present in search doesn’t guarantee a visit the way it once did.

Let’s take another look at Hubspot. Its traffic collapse grabbed everyone’s attention, and its bounce-back? Also worth paying attention to. Despite the traffic drop, HubSpot maintains a 35.3% share of voice in AI-generated answers for their category, and commands over half of all brand mentions in their space.

Yes, they lost their click, but they maintained their authority. Your report has to show the distinct difference between those two now.

How to Optimize for AIO Visibility (A Practical Framework)

While we don’t have a checklist for getting citations in AI Overviews (no thanks to Google’s tight lips), we’re observing patterns in what gets surfaced and what doesn’t.

So, here’s a checklist you can use in your content strategy going forward to throw your hat in the game.

1. Build Topic Clusters, Not Isolated Pages

Cover topics in depth across multiple pieces. This establishes authority and gives Google more context to work with.

One reason Hubspot was able to bounce back quickly was because their traffic loss was concentrated in pages like “famous sales quotes” and “flush DNS” . These didn’t really have anything to do with their core business.

Pages with genuine topical depth in their core subject area held up far better. Broad coverage without deep expertise is now a liability.

2. Answer Questions Fully, Not Partially

Shallow answers are easy to skip over. Address the query completely, including related sub-questions where it makes sense.

This is important for AIO inclusions specifically because Google’s synthesis process compresses content. If your answer is already shallow, compression leaves almost nothing.

You need to answer every question related to the query including follow-up questions a reader would ask.

3. Structure Content for Extraction

Use clear headings, focused paragraphs, and logical flow. Ask whether a section could stand on its own and still make sense.

As mentioned earlier, AI Overviews average around 169 words when expanded. That’s roughly two focused paragraphs. If your best answer to a query is buried in a 2,000-word article with no clear heading structure, Google is unlikely to find and use it.

Each section of your content should be able to answer its heading question without relying on the sections around it.

4. Demonstrate Real Expertise

Generic advice disappears into the noise. Specific, experience-based insight stands out. Use examples and practical detail wherever you can.

If your content contains data that doesn’t exist anywhere else, Google’s model has to cite your source to reference it.

For us at DriveTraffic, that means drawing on client account data, campaign results, and patterns we see across industries.

AI can summarize the internet. It can’t summarize your direct experience.

5. Strengthen Internal Linking

Connect related content in a way that reinforces your coverage of a topic. This helps both user navigation and how search systems understand your site.

On authority signals, citation data tells us that brands are 6.5 times more likely to be cited through third-party sources than their own domains.

That means your internal linking strategy works alongside external signals — PR, industry mentions, guest contributions — not instead of them. If you want to show up in AI Overviews, you need people talking about you elsewhere on the web, not just on your own site.

Across all of this, clarity beats cleverness. If something is hard to follow, it’s less likely to be used.

Measuring Success in a Zero-Click World

This is where things get less straightforward.

Some teams are seeing stable rankings alongside declining traffic. That’s a hard thing to explain when you’re reporting performance.

Look beyond rankings. Other signals become more useful:

Impressions
Growth in branded searches
Assisted conversions
Engagement from users who do click through

Shifting the focus toward overall visibility and business outcomes makes for a clearer picture than clicks alone.

Tracking direct inclusion in AI Overviews is still limited. For now, it takes observation and trend analysis — not precise measurement.

Organizations are catching on gradually, and shifting success metrics from clicks and traffic to visibility and share of voice. So now, the question isn’t just “are we getting clicks”, it’s “when someone searches for what we do, are we part of the answer?”

Set up a regular cadence of manually checking whether your brand or content appears in AI Overviews for your most important queries. It takes ten minutes and tells you more than a ranking report does.

Who Needs to Care About AIO Right Now?

As much as AIO cuts across the majority of industries, its impact isn’t the same across the board.

Higher priority:

Publishers relying on informational traffic
Affiliate sites
SaaS companies using content for lead generation

Moderate priority:

Businesses with a mix of informational and transactional content

Lower immediate impact:

Pure e-commerce sites focused on product searches

If a large portion of your traffic comes from informational content, this needs your attention immediately.

Semrush data shows that health, science, education, and legal categories face the highest rates of AI Overview appearance, with science queries up 22.27%, health up 20.33%, and law and government up 15.18% between January and March 2025. If your clients are in healthcare, legal services, or education, the exposure is already significant.

For B2B and SaaS specifically: B2B tech queries now trigger AI Overviews 70% of the time, and some sectors are seeing 70-80% organic traffic drops.

The how-to guides, glossary pages, and comparison articles that B2B marketers spent years building are the most vulnerable to AI summarization.

Common Misconceptions About AIO

“SEO is dead.” It isn’t. It’s changing.

“Ranking number one guarantees inclusion.” It doesn’t. AI Overviews pull from multiple sources.

“AIO appears everywhere.” It doesn’t. Coverage is still uneven.

“Clicks are gone.” They’re reduced in some cases, not eliminated.

It’s easy to overreact in this industry because of how volatile it can get, however, we need to be clear on facts, and take informed decisions, not sensational ones.

What This Means for the Future of Search

From what I’ve observed, it’s clear to me that AI Overviews will likely expand with more queries triggering them. We’re also going to see changes in search experience and user behavior.

Despite the major shake-up and effects of AIO, there are still questions about accuracy, attribution, and how publishers will be affected long term.

Right now, all you can do is stay flexible and keep a close watch on how your key queries are evolving. Be open to testing and don’t lock in on assumptions too early.

From all my years of experience in search, I can confidently say that it’s never been a smooth-sailing industry. We’ve always had changes that rock the boat — this one just seems more visible than most.

Lots of publishers aren’t sitting down quietly either.

The likes of Chegg and Penske Media have filed antitrust charges against Google on the claim that Google is engaging in “coercive reciprocal dealing” — using its monopoly power to force publishers to accept unfavorable terms they would reject in a competitive market.

These lawsuits won’t reverse what’s already happened, but they may shape how Google handles attribution and citation going forward. Let’s keep an eye out for what happens next.

There’s also an opportunity to watch for here. ChatGPT referrals to news sites grew from approximately 1 million visits in early 2024 to 25 million in 2025.

AI Platforms are also beginning to send out traffic, not just absorb it. If your content is structured to be cited by AI systems generally, not just Google’s specifically, you’re building for a broader opportunity.

Bottom Line: SEO Isn’t Dead, But It’s a Different Game Now

When changes like this happen, people are often quick to throw the fundamentals out the window. Don’t.

You still need the fundamentals of SEO to compete, including some added layers.

Search is no longer just about ranking pages, but about being a trusted source that contributes to an answer.

If your strategy depends entirely on clicks, it will feel shaky. If it’s built around clarity, authority, and genuine usefulness, it has a much better chance of holding up.

I’ve been in digital marketing since the mid-90s, and the patterns that survive every major shift are the same ones: understand your audience better than anyone else does, produce content that actually helps them, and build relationships that hold up when the algorithm changes.

AI Overviews don’t change that. They just make it more obvious when you haven’t done it.

The teams that adapt early tend to do better because they focus on what actually matters and move with it.

Frequently Asked Questions (FAQs) About Google AI Overviews

My rankings haven’t moved but my traffic is down significantly. What’s actually happening?

What’s most likely happening is that your page still ranks where it did, but an AI Overview is now sitting above it and answering questions before the user gets to you. It’s even possible that your impression count will increase, but the click never comes.

If you’re seeing impressions or hold while your CTR drops, that’s your signal to filter your top informational keywords and check how many are now triggering an AIO.

Can I see which of my pages are being used in AI Overviews?

Not directly, and this is one of the more frustrating parts of the current situation. Google hasn’t built a clean AIO-specific filter into Search Console. There’s no way to isolate regular organic data from AIO clicks.

What you can do: use Ahrefs or Semrush to filter your keyword rankings by SERP features and look for the AI Overview flag. That tells you which of your ranking keywords are triggering one. From there, manually spot-check those queries in Google to see if your content is being cited.

My content is being used in an AI Overview but I’m not getting cited. Does that happen?

Yes, and it’s more common than most people realize. Google’s synthesis process pulls from multiple sources to build the overview, but not every source that contributed to the answer gets a visible citation. Your content may have influenced the response without earning the link.

If you suspect your content is being used but not credited, the clearest fix is to make your content more distinctly attributable — proprietary data, original research, specific frameworks with your name on them.

Is there a way to opt out of being included in AI Overviews?

Technically, yes. Google has said that pages using the nosnippet meta tag can prevent their content from being used in AI Overviews. But I’d be careful about doing that.

Opting out means you won’t be cited and won’t benefit from inclusion — including the CTR uplift that comes with being a cited source. For most sites, that’s a worse outcome than being in the overview without a click. The exception might be paywalled content or proprietary research you don’t want summarized without subscription.

For the vast majority of SEOs, the goal should be getting cited, not opting out. Optimize toward inclusion, not away from it.

Is top-of-funnel content basically dead now?

Not dead, but it’s the part of your content portfolio that’s under the most pressure right now, and you need to be honest about that in your planning.

Top-of-funnel informational content is exactly what AI Overviews were built to answer. If your ToFu strategy is built around driving volume through broad informational queries, that model is getting harder to sustain on clicks alone.

What’s changing is the purpose of that content, not its existence. ToFu content that earns AIO citations builds brand visibility even without clicks.

The mistake would be cutting ToFu entirely. The smarter move is being realistic that it now contributes to awareness and authority more than it contributes to session volume — and reporting it accordingly.

Should I be optimizing for ChatGPT and Perplexity separately from Google?

The tactics overlap significantly, but the citation dynamics are different enough that it’s worth understanding both.

Google’s AI Overviews pull heavily from pages that already rank in the top 10 — 76% of AIO citations come from there. So for Google, traditional SEO fundamentals still matter a lot.

ChatGPT and Perplexity behave differently. Research from Ahrefs found that about 80% of LLM citations don’t even rank in Google’s top 100 for the same query. These systems cast a wider net and are more likely to pull from Reddit threads, community forums, YouTube, niche publications, and third-party brand mentions than from your own site directly.

What this means practically: for Google AIO, keep doing SEO well. For ChatGPT and Perplexity visibility, your priority is third-party presence — getting your brand and your people mentioned on sites those systems trust.

You don’t need a completely separate strategy, but you do need to understand that “rank on Google” won’t get you into every AI answer anymore.

A note on the data cited in this article: The studies referenced above — from Seer Interactive, Pew Research Center, Ahrefs, Semrush, and BrightEdge — represent the best available research as of early 2026. This is a fast-moving area. Figures will continue to shift, and I’ll update this post as new data emerges.
