What is AI Response Optimization?

AI Response Optimization (AIRO) is the practice of refining and structuring your content so that it gets summarized in zero-click answers, such as Google’s AI Overviews, featured snippets, and “People Also Ask” results.

AIRO is better known as Answer Engine Optimization (AEO), but it’s all part of a larger strategy: Generative Engine Optimization (GEO).

While AIRO is focused on capturing a zero-click summary, GEO has a broader objective: to make your content visible and, crucially, cited as a source by generative AI platforms, like ChatGPT and Perplexity.

Simply put, AIRO is the targeted effort, while GEO is the broader strategy.

AI Response Optimization vs Traditional SEO

Don’t get it wrong: traditional SEO principles remain the bedrock of a healthy online presence. And I’m not just saying that because we’re an SEO agency (we have a stake in AI SEO optimization as well, FYI). I’m saying that because many tactics that you’ll find success with in SEO, you’ll also find success with in AIRO, AEO, and GEO.

Actually, I made a meme for our socials, making this exact point only a few days ago. I captioned it: “90% new acronyms, 10% new tactics.” Which basically sums it up: There are some differences between optimizing for AI, sure. But many of the strategies and tactics we already use in SEO work for AI SEO, too.

The best evidence of this is that websites that haven’t done a skerrick of AIRO or GEO appear in AIOs just fine. Coincidence? Sure, perhaps. Skeptical? Let’s look at some numbers, not just rely on my anecdotes.

Louise and Xibeijia over at Ahrefs uncovered these results in a recent study, and I quote:

• “76.10% of AI Overview-cited pages rank in the top 10”
• “9.50% of AI Overview-cited pages rank between position 11-100”
• “14.40% of pages cited in AI Overviews do not rank in the SERPs (i.e., rank below position 100)”

There’s some serious crossover here, you know, between AIRO and SEO. So, let’s start from there:

What AIRO and SEO Have in Common

The good news is that AI Overviews and other generative AI platforms do their damnedest to sniff out trustworthy, authoritative sources, which are the fundamentals you’ve been building on for years.

So let’s lean on Ahrefs once again to see what factors help you appear in both organic results and AIOs.

In this study, Ahrefs found that branded mentions, branded anchors, and branded search showed a moderate correlation of appearing within AIOs. Referring domains and backlinks showed a weaker correlation, but they did have some, if a small, impact on whether a site would appear in AIOs or not.

Of course, all these factors are either confirmed SEO ranking factors or widely accepted as such. Meaning, there is a crossover between SEO and AIRO. This intuitively makes sense, right? AI Overviews is a Google product, so you’d expect Google ranking factors to have some influence on AIO’s appearance.

What AIRO and SEO Don’t Have in Common

So, the fundamentals are still there. But the goalposts have moved, requiring a shift in strategy and a new set of tactics to align with the tastes and preferences of AI.

The most obvious change is the goal itself.

What I mean by this is that the primary objective is no longer just to rank in the top 10 of a traditional SERP. Nope, the new game is to get your content included in a summary or cited as a source in an AI-generated response.

This pivot from a click-centric to a citation-centric model changes everything about how we measure success.

We still care about rankings and click-through rates, of course, but we now also need to track things like citation frequency, citation share of voice, and citation retention rate to understand how our content is performing in AI Overviews and other generative platforms.

And with fewer clicks happening, brand presence becomes more important. Even if a user doesn’t click, they’ll still see your brand name. This is called an AI brand mention. Meaning, trust signals, topical authority, and recognition carry extra weight.

Content “freshness” is also a difference worth pointing out. While traditional SEO has long favored well-optimized, long-standing “evergreen” content, new research from Ahrefs suggests that many generative AI platforms show a strong preference for citing more recent content.

So, a higher frequency of content updates and the publishing of fresh content is now a direct signal that you need to optimize for if you want to appear in AI Overviews and other AI-driven platforms.

Why AI Response Optimization Matters Now

The evidence is clear. We’re seeing a shift in how users find information. Users want quick, fluff-free answers to hyper-specific questions. It’s a case of the chicken and the egg. Do users want quick answers out of preference? Or do they want them because they’re using AI platforms like ChatGPT and Google SERP features like featured snippets?

At the end of the day, it doesn’t really matter. The reality is that this demand is here, and it’s being met by AI platforms. The result? AI referrals have already surged 357% year-over-year, reaching 1.13 billion visits to the top 1,000 websites in June 2025, with ChatGPT alone accounting for over 80% of that traffic. The growth is even more dramatic in news and media, where AI referrals spiked 770% over the past year.

But why the sudden change? One reason: it’s a generational shift. Younger users, including Gen Z and below, are increasingly bypassing traditional search engines altogether. A Forbes survey found Gen Z is 25% less likely to use Google for brand discovery than Gen X. In fact, 41% of Gen Z now start their search journey on social media, ahead of search engines (32%) and chat-based AI tools (11%).

They’re turning directly to conversational AI tools, including Google AI Overviews for synthesized answers. This new breed of user trusts the content and insights presented in these AI answers, especially when it’s transparently sourced from a reputable authority.

True or not, they see the AI not as a single opinion but as an aggregator of multiple reputable sources, which can be perceived as more balanced and trustworthy than a single article.

Beyond the younger gens, a comparative study found ChatGPT users across different education levels reported higher satisfaction and perceived information quality than Google users, even when task performance was similar. If you use X (Twitter), you’ll see this in real-time when people interact with the platform’s in-built AI tool, Grok.

So, what does this all mean for the future of search? Is SEO dead? Heck no!

The traditional tactics that got you to the top of the SERP still matter, but they are no longer enough on their own. The shift toward AI-powered platforms and user demand for synthesized answers means that successful SEO is becoming a multidisciplinary field, combining traditional optimization with the science of AI response and content strategy.

Your job is now to ensure your content is not only a top search result but also a trusted source for an AI that is becoming a user’s first point of contact.

How AI Overviews Process and Surface Responses

AI Overviews’ generative summaries are built on a custom Gemini model that works in tandem with Google’s existing Search systems and the Knowledge Graph. They are designed to appear when Google’s systems determine that an AI-generated summary would be genuinely additive to classic search results.

The Pipeline at a Glance

The process from a user query to a live AI Overview is a multi-stage pipeline:

1. Interpret the Query: The process begins with the AI system interpreting the user’s query. Google may break down the initial question into multiple related sub-queries, a process known as “query fan-out,” to explore various subtopics and data sources, allowing the system to build an understanding before it even begins to compose an answer.
2. Retrieve Candidates from the Web and Knowledge Graph: Based on its interpretation and fan-out queries, the system retrieves relevant information from Google’s vast web index and its Knowledge Graph. This step, where traditional quality and ranking systems still play a significant role, ensures that the information being pulled to corroborate the final response comes from a trusted foundation.
3. Synthesize with Gemini: Once a set of credible source candidates has been retrieved, the Gemini model synthesizes across this evidence. It composes a new, concise summary, rather than just copying and pasting from a single source.
4. Surface Citations in the UI: Finally, Google displays the AI-generated overview in the UI, attaching links to the cited sources.

How Sources Are Chosen (Signals You Can Influence)

According to Google’s own documentation, there are no special “AIO-only” technical requirements beyond standard eligibility for Search snippets. AIOs may show a wider, more diverse set of helpful links than classic web search due to the fan-out process during generation.

Not to take Google at their word, large-scale studies, like the ones I cited earlier, consistently suggest an overlap between AIO citations and top organic results.

In fact, a significant percentage of AI Overview-cited pages rank in the top 10 of a traditional SERP for either the original or a fan-out query. This reinforces that classic SEO signals like high-quality content, backlink authority, and a strong domain foundation still serve as the primary signals for getting your content considered.

Knowledge Graphs, Semantics, and Entity Alignment

A key factor that gives your content an edge is its alignment with how AI systems understand the world. AI systems favor entity-rich, semantically structured content that aligns with knowledge graph models for clarity and recall.

If a search engine’s Knowledge Graph understands that “The Beatles” are a “band” with “members” like “John Lennon,” your content is more likely to be cited if it makes those connections clearly.

Differences vs. AI Mode (Context)

While both AIO and AI Mode use fan-out queries, there are subtle but important differences. AI Mode, which is a conversational experience, leans into deeper reasoning and exploration. It may use different model settings and techniques, and its conversational nature means that the response sets and cited links can vary significantly between AIO and AI Mode for the same initial query.

Conclusion and Next Steps

Your TL;DR:

1. AI Response Optimization (AIRO) is about one thing: getting your content cited in AI-generated answers, not just ranking in the traditional SERPs.
2. Structural clarity, aligning with how AI processes information, and demonstrating freshness and authority are your competitive edge.
3. SEO is still the foundational bedrock of everything you do. AI-first optimization is the new layer you should be building on top of it.
