What Is “Answer Engine Optimization” and Why It Matters for Business in 2025

Search engines have changed beyond recognition in recent years. If in the past the main task for businesses was to secure a spot in the top 10 and wait for clicks on links, today the rules of the game have been rewritten. More and more often, users now receive a ready-made answer directly in the search results — without ever needing to visit websites.

This shift has become especially pronounced with the rise of generative technologies: Google AI Overviews, Microsoft Copilot Search, Perplexity, and other engines that don’t just show a list of links, but instead construct a coherent response by merging information from multiple sources.

For companies, this is both a challenge and a new opportunity. On the one hand, the traditional strategy of “SEO = rankings” no longer guarantees visibility. Even if a website is ranked first, it may go unnoticed if the search engine surfaces the information in its own answer block. On the other hand, brands now have the chance to appear directly in those answers — and be closer to the customer than ever before.

Answer Engine Optimization (AEO) is a new field of digital marketing that helps businesses not just “be in search results,” but actually be at the heart of the user’s query. In 2025, AEO is becoming what SEO was ten years ago: a mandatory tool for anyone who wants to grow and compete on equal footing.

From SEO to AEO: How Search Has Changed

History: From Directories and Keywords to AI Answers

The history of search engines reflects how people learned to navigate the ocean of information. In the 1990s, the internet was small and poorly structured. Popular services were directories like Yahoo Directory or DMOZ, where websites were added manually. Search worked more like browsing a table of contents in a library.

Everything changed with the arrival of Google. The PageRank algorithm, which took into account links between websites, made it possible to sort pages by relevance. From that moment on, SEO became the main tool of digital marketing: the right keywords in text, meta-tags, backlinks — and a company could climb into the top search results.

For almost twenty years, SEO determined online visibility for businesses. But by the mid-2010s, it became clear that search queries were becoming more complex. Users were less likely to type things like “buy laptop Minsk” and more likely to ask fully formed questions such as “which laptop is best for a designer in 2025?” Traditional algorithms struggled with this complexity, paving the way for a new era — the era of answers.

People are asking increasingly complex questions, and our job is not just to provide a list of links, but a comprehensive, coherent answer. – Sundar Pichai, CEO of Google

This was the foundation for the emergence of generative search, where answers — not positions — became central.

What Is an Answer Engine (Examples: Google AI Overviews and Perplexity)

An Answer Engine is a next-generation search technology. Unlike classic search, it doesn’t just index pages — it generates a coherent response using a combination of ranking algorithms and generative AI.

Google AI Overviews became the first large-scale implementation of this idea. Launched in 2023, by 2025 they are available in 100+ countries, reaching more than a billion users per month. When a user types a query, Google forms a block with a ready-made explanation — sometimes a table or step-by-step list. Links to sources remain, but they are embedded into the text as validation, not as the main element of the results page.

Another example is Perplexity AI, a service that calls itself “an answer engine by design.” Unlike Google, Perplexity builds an explicitly conversational experience: you type a question, and the system provides a detailed response with cited sources. For many users, it feels closer to talking with an expert than using a traditional search engine.

Comparison of models:

Model	How It Works	Role of Website	Role of User
Classic Search	List of links based on keywords	Source of clicks	Chooses which page to open
Answer Engine	Ready-made answer from multiple sources	Fragment for citation	Gets value immediately

Thus, websites are no longer the final destination, but building blocks for generating answers. For businesses, this means: it’s not enough to be indexed — you need to make it into the shortlist of trusted sources from which answers are built.

Why Classic SEO No Longer Guarantees Visibility

Many companies still think in SEO terms from a decade ago: “as long as we’re in the top 3, traffic is guaranteed.” But reality is already different. Even if a site ranks first, it may not get clicks if Google or Perplexity includes the answer directly in the AI block.

This leads to a paradox: positions are maintained, but traffic falls. Studies show that click-through rates for traditional results drop by 20–40% in areas where AI answers are heavily used. Users often get enough information from the block itself and no longer need to click through.

In the new model, the winners are not those ranked highest in search, but those chosen by the algorithm as worthy of citation. – Rand Fishkin, SparkToro

In other words, SEO in its classic sense is no longer a guarantee of visibility. For businesses, this is a risk: you can keep investing in content, but real leads will decrease. That’s why AEO — optimization for Answer Engines — comes to the forefront.

The Difference Between SEO, AEO, and GEO

To properly integrate this new discipline into a marketing strategy, it’s important to distinguish between the three terms:

• SEO (Search Engine Optimization). The classic approach: optimizing a website for higher positions in search results. Metrics: CTR, rankings, organic traffic.
• AEO (Answer Engine Optimization). Optimization for engines that generate answers. The goal: to have your site cited inside AI blocks. Metrics: mentions in answers, clicks from AI Overviews, leads generated directly from those blocks.
• GEO (Generative Engine Optimization). A broader concept: optimization for any generative systems — search engines, chatbots, voice assistants, even AI systems inside social media.

In practice, AEO is the applied part of GEO, focused specifically on search. And in 2025, AEO becomes the core discipline: no longer an experiment, but the foundation of digital marketing.

Search has evolved from directories and keywords to generative engines. Users no longer want to choose a link — they want a ready-made answer. For businesses, this means that classic SEO can no longer guarantee traffic. AEO and GEO now take center stage — strategies that help brands appear in AI-generated answers and maintain direct contact with their audience in this new reality.

AEO in 2025: What It Means for Business

Answer Engine Optimization (AEO) has stopped being an experiment and has become part of daily business reality. If in 2023–2024 many companies still treated AI Overviews or Perplexity as “add-ons” to search, by 2025 it became clear: this is a new standard. The scale of adoption, the speed of user adaptation, and new behavioral patterns make AEO as essential to a marketing strategy as SEO was ten years ago.

Scale: 1+ Billion Users of AI Overviews and the Rise of Alternative Engines

Google officially announced that AI Overviews now reach over one billion monthly users. For comparison, that’s an audience on par with Instagram or YouTube during their global growth stages. In other words, generative answers have already become a mainstream channel of communication between brands and users.

And Google is not the only player. Microsoft Copilot is embedded into Bing and Windows. Perplexity is gaining traction among early adopters and is already widely used by professionals in the US and Europe. At the same time, niche answer engines are emerging for industries like medicine, law, and finance.

The search engine of the future is not a list of links, but a personal advisor. Companies must prepare for a world where customers expect answers here and now. – Satya Nadella, CEO of Microsoft

The scale makes one thing clear: ignoring AEO is no longer an option. This isn’t a trend for early adopters — it’s mainstream reality.

How User Behavior Is Changing

Users have quickly adapted to the new format. Where the average search query once contained 2–3 keywords, in 2025 “conversational” queries dominate: typically 6–8 words or more. People now phrase their queries as if speaking to a consultant, not a machine.

Example:

• Old style: “best CRM 2023”
• New style: “which CRM is best for a startup with a team of up to 10 people”

Instead of clicking through dozens of links, the user gets one comprehensive answer. This shift changes traffic mechanics.

Behavioral trends:

• Growth in long-form, highly specific queries.
• Fewer website visits (20–40% lower CTR in niches with AI blocks, depending on the data source).
• Rising trust in AI-generated answers: users increasingly treat them as “objective truth.”

For businesses, this means competition is shifting from the top 10 links to the top sources that the system deems citation-worthy.

New KPIs: Mentions, Clicks from AI Blocks, and Leads Instead of Traffic

Traditional SEO metrics are losing relevance. Rankings and CTR no longer reflect reality. A business might be “#1 in search” and still lose visibility if the answer has already been surfaced in an AI block.

Instead, new KPIs are emerging — the ones marketing teams are starting to track:

• Mentions in AI answers. How often a site is cited in Overviews or Perplexity.
• Clicks from AI blocks. When users do click, it’s important to track which AI block drove them.
• Incremental value. How much warmer and more conversion-ready AI leads are compared to regular SEO traffic.

Comparison table:

Old SEO Metrics	AEO Metrics
Rankings in SERPs	Mentions in answers
CTR	Clicks from AI blocks
Organic traffic	Leads from AI answers

Thus, effectiveness is no longer measured by “traffic for the sake of traffic,” but by real business value.

Risks: Losing Visibility by Not Adapting

As with any transformation, the shift to AEO comes with risks. The biggest is invisibility for companies that continue to rely solely on traditional SEO.

Imagine two competitors:

• The first optimizes for AEO — structured content blocks, FAQs, schema markup, expert quotes.
• The second keeps “pumping out keyword-driven text.”

In AI Overviews, users will see the first brand. The second will remain invisible — even if it holds higher rankings in organic search.

Invisibility in Answer Engines is the new invisibility. Your site may exist, but for the customer, it doesn’t. – James Murray, digital marketing researcher

That’s why in 2025 AEO is no longer optional — it’s a necessity. Those who adapt will maintain contact with customers. Those who don’t risk losing a channel that, until recently, delivered the majority of leads.

Answer Engine Optimization in 2025 is not “a trend,” it’s reality. The scale of AI Overviews adoption, the change in user behavior, and the shift in metrics make AEO a required part of any marketing strategy. Businesses must learn to compete not just for rankings in search results, but for placement inside AI answers. Otherwise, the risk of being left “in the shadow of algorithms” becomes too high.

How Answer Engine Optimization Works

To understand why AEO is becoming a mandatory part of digital marketing, it’s important to unpack how answer engines actually build their blocks. A generative engine is not a “black box” that randomly selects websites. It’s a complex combination of ranking algorithms, data structure analysis, and trust evaluation. And while Google, Microsoft, or Perplexity don’t disclose their exact formulas, the principles are clear: the winning content is the one that is easiest to cite and helps the system deliver a quick, clear answer to the user.

The Principle of Source Selection for Generative Answers

Answer Engines operate differently from classic search engines. While SEO competes for “placement” in search results, AEO competes for a “role” inside the answer itself. The algorithm doesn’t just look for relevant pages — it constructs a coherent piece of text. For that, it needs content fragments that are easy to insert directly into the answer.

In general, the system weighs three factors:

• Completeness of the answer — the text must directly respond to the question.
• Clarity of wording — the simpler and more structured the fragment, the higher its chances.
• Trustworthiness of the source — the site must be authoritative enough for its citation to appear reliable.

Google notes in its developer documentation: “Our models select fragments that help the user get an answer faster.” In other words, even perfectly optimized text will not appear in an Overview if it does not provide a direct and understandable answer.

The Role of Structured Data

Another core aspect of AEO is that generative search engines prefer structure. It is easier for the algorithm to take a ready-made block — a table, a step-by-step guide, an FAQ — than to reprocess a long paragraph of prose. This is why implementing structured data has become a critical tool.

Schema.org types — FAQPage, HowTo, Article — send signals that information is broken down into logical blocks and can be presented in user-friendly form. Step-by-step instructions or FAQs are almost guaranteed to surface in AI answers, at least partially.

Structured data is the new language of communication with search engines. The clearer you mark your content, the higher the chance it will be used in answers. – John Mueller, Google

Thus, AEO requires thinking not only about what you write, but also how you format it. Content must be technically “readable” for algorithms.

EEAT Signals: Expertise, Authoritativeness, Trustworthiness

Structure alone is not enough. Answer Engines heavily rely on the EEAT framework (Expertise, Experience, Authoritativeness, Trustworthiness). This concept first gained traction in SEO years ago, but in the age of generative search, it has become mission-critical.

The algorithm must not only find the right text but also verify that it comes from a reliable source. For example: if you run a medical website with no author attribution, no citations to research, and no visible contact information, your chances of being included in AI answers are minimal. Conversely, an expert article signed by a credible author, with references to peer-reviewed journals and transparent company details, is far more likely to be cited.

Examples of EEAT signals:

• The author is named and has verified expertise.
• References to authoritative sources (journals, studies).
• The brand or company is mentioned in the media.
• The site is transparent: contact details, privacy policy, “About Us” page.

Google emphasizes in its guidelines: “We aim to show users information they can trust. Sources must demonstrate transparency and expertise.” For businesses, this means working not only on SEO but also on brand reputation.

Content That Surfaces in AI Answers

On a practical level, several content formats are especially likely to be surfaced by generative systems:

• Short fragments that directly answer a question — concise 2–3 sentence paragraphs.
• Tables and comparisons — easy for the algorithm to extract and insert.
• Step-by-step instructions — the HowTo format fits AI blocks perfectly.
• FAQ sections — a universal way to provide quick answers to common questions.

Example: If a user searches “how to set up two-factor authentication in a SaaS app,” the AI Overview may show a direct step list: “Open settings → select Security → enable 2FA.” If you were the one to provide this sequence in structured form, your chances of being cited increase dramatically.

Answer Engines choose fragments that can be displayed without distortion. That makes brevity and clarity the key competitive advantages. – Bill Slocum, Perplexity

The Intersection of Relevance, Structure, and Trust

Answer Engine Optimization works at the intersection of three dimensions:

1. Relevance of the answer.
2. Technical structure of the content.
3. Trustworthiness of the source.

To appear in AI blocks, businesses must not only create high-quality content but also format it in ways that algorithms can easily use. Concise fragments, structured data, and strong EEAT signals are the new “currency of visibility” in the search landscape of 2025.

Practical AEO Strategy for Businesses

Answer Engine Optimization is not theory — it’s an applied discipline. For a business, it’s not enough to simply understand what AEO is; it’s critical to build a concrete strategy so that your site actually appears in AI-generated answers. Unlike classic SEO, success here doesn’t depend on the “number of pages” or the “volume of backlinks,” but on how well the site is prepared for generative engines — in terms of content, structure, and brand trust.

Auditing Your Current Website: Is It Ready for Answer Engines?

The first step is diagnosis. Most companies still optimize exclusively for classic search and don’t realize that their content is practically “unreadable” for Answer Engines.

Questions to ask during an audit:

• Are there fragments on the site that directly and briefly answer user questions?
• Are FAQ sections, tables, or step-by-step instructions used?
• Does the site contain structured data (Schema.org)?
• Are the services/products explained in a way that a non-expert can easily understand?

Mini-example: A page that says, “Our cloud infrastructure solutions enable businesses to achieve innovative growth,” is essentially empty text for AI. But a paragraph like, “Cloud infrastructure = renting computing power and storage from a provider instead of buying servers,” is usable in an AI-generated answer.

Content Optimization: Writing “for Answers”

In the AEO era, content must be not only long and expert-level, but also algorithm-friendly. The main principle: write so that an answer can be extracted and displayed on its own.

This means following several rules:

• Key questions should be written as subheadings.
• Answers should be short, clear paragraphs (2–3 sentences).
• Complex information should be presented in tables or lists.
• Each short answer should be accompanied by extended context nearby.

Good AEO content combines encyclopedic brevity with expert depth. — Neil Patel, marketer and SEO author.

This format works for both the user and the algorithm: the first gets clarity, the second gets ready-to-use material for citation.

Technical Foundation: Speed, Microdata, API Integrations

Even the best content won’t make it into AI answers without a solid technical base. Algorithms take into account how quickly a site loads, how well it displays on mobile devices, and whether microdata is present.

Schema.org microdata is essentially a “hint” for algorithms. Markups like FAQPage, HowTo, and Article help search engines understand the structure of a page. If the content is properly marked up, the probability of being included in an answer block rises significantly.

In addition, API integrations are becoming increasingly important. Google and Microsoft are already testing formats that allow direct access to company data via APIs. Businesses that provide structured data in this way will receive priority.

Takeaway: Speed + structured data + transparent APIs = the basic technical foundation of AEO.

Synergy with Other Channels: Social Media, Partner Content, PR

AEO should not be treated in isolation from your overall marketing strategy. Algorithms evaluate not only your site but also your brand’s presence in the wider information ecosystem.

• Social media provides signals of “live presence”: expert posts and quotes strengthen trust.
• Partnerships and guest posts reinforce the brand as an authoritative source.
• PR in professional media serves as an additional EEAT signal: if industry outlets cite you, your chances of appearing in AI answers increase.

Thus, AEO is directly tied to digital reputation. The more trust your brand builds across channels, the higher the likelihood that the algorithm selects it as a source.

Case Studies: Brands Already Winning with AEO

The first examples of success are already visible.

• FinTech companies in the U.S. noticed that articles with clear definitions and step-by-step instructions began appearing in Google AI Overviews more frequently than competitors’ long-form content.
• Medical startups invested in expert content with articles authored by doctors. As a result, they grew traffic from AI blocks even though their organic rankings were average.
• SaaS services implemented knowledge bases in FAQ and HowTo formats. This resulted in their answers surfacing for queries like “how to connect” or “how to set up,” leading to an increase in demo requests.

We saw that it wasn’t top positions, but rather inclusion in AI answers that started driving leads. This radically changed our approach to content. — HubSpot Research case study.

These cases show that AEO is not “something for the future” — it is already working today.

Summary: Content, Tech, Reputation

A practical AEO strategy is built across three layers:

• Content — write in fragments that can be lifted into answers.
• Technical base — speed, schema markup, API readiness.
• Reputation — signals from PR, partnerships, and social media.

The roadmap: audit your site, rewrite key materials “for answers,” strengthen the technical foundation, and build digital authority in parallel. Results may appear within months because Answer Engines update faster than traditional search indexes.

For businesses starting AEO in 2025, the competitive advantage is clear: their brand will appear directly inside the answers where customers expect to find solutions. That means leads, trust, and growth — without having to “fight” for top positions in classic SEO.

The Future of AEO: Forecasts and Roadmap for 2025–2026

Answer Engine Optimization is currently in a phase of rapid emergence. To draw a parallel, it’s like the early 2010s for classic SEO: it’s already obvious that the tool is vital for business, but there are still no established standards or turnkey solutions. By 2025–2026, AEO will no longer be an experiment for a few companies — it will become a mandatory element of marketing strategy. A business’s competitiveness in the coming years will depend directly on how quickly it adapts.

How Answer Engines Will Impact Competitive Markets

The biggest changes will come to industries with high competition and information density. In markets where dozens of players fight for customer attention, a place in an AI-generated answer will be more valuable than a top ranking.

• SaaS. Companies that build knowledge bases, publish step-by-step guides, and provide clear answers will appear in Google Overviews or Perplexity more often than competitors. If your product shows up in an answer block with text like, “To automate your hiring process, use…,” the likelihood that the user clicks on you rises dramatically.
• E-commerce. Here we’ll see direct traffic redistribution. Traditional “Top-10 product” lists will disappear. Answer Engines will deliver structured reviews instead: “The best smartphones of 2025” will no longer be a set of links but a generated comparison. Stores that get cited will win the lion’s share of traffic; those left out may lose up to 50% of their organic visitors.
• FinTech. For financial and banking services, trust will be paramount. Algorithms will favor companies with transparent licensing, links to regulators, and expert commentary. Startups without validated expertise risk becoming invisible.

Answer Engines are the new storefront. If you’re not there, you don’t exist for the customer. — Brian Dean, founder of Backlinko.

Thus, AEO is not just another tool — it is a true survival factor in competitive markets.

Metrics of the Future: “Share of Answers” as the New CTR

The paradigm shift in search means a change in metrics. CTR by position in search results no longer reflects reality: the user sees an AI-generated answer and often doesn’t click further.

A new metric is emerging: Share of Answers — the proportion of times a brand or website is mentioned in AI-generated answers within its niche. This becomes the new “currency of visibility.”

Yesterday’s Metric	Tomorrow’s Metric	What It Actually Shows
CTR	Share of Answers	How often a brand appears inside AI blocks
Organic traffic	Traffic from AI answers	The value of citations in lead generation
Top-10 positions	Mentions and quotes	The algorithm’s trust in the source

Companies that start measuring these indicators early will gain an advantage. Specialized AEO-tracking services are already emerging — still in their infancy, but within a couple of years they will be as standard as SEMrush or Ahrefs were for SEO.

First Steps: What Businesses Should Do Now

The future of AEO looks large-scale, but preparation must begin today. Google, Microsoft, and Perplexity are constantly updating their source databases, and the “spots in the sun” will go to those already present with quality content.

Step-by-step plan for businesses:

1. Audit. Check if your site has content that can easily be used in AI answers: short paragraphs, FAQs, tables, step-by-step instructions.
2. Content. Rewrite key materials so that they directly answer client questions (“What is it?”, “How to use it?”, “What makes it different?”).
3. Technical. Add Schema.org microdata, speed up page loading, and check mobile responsiveness.
4. Reputation. List authors, validate their expertise, and publish in industry media.
5. Monitoring. Start tracking whether your site appears in AI answers (for now, this can be done manually; later, specialized services will emerge).

In the race for Answer Engines, it’s not those with the biggest budgets who win, but those who started earlier. — Sarah Watson, Forrester.

Long-Term Outlook: AEO as Part of Digital Strategy

In one to two years, AEO will stop being a “separate trend” and will become embedded into overall digital strategy. SEO specialists, content marketers, PR teams, and developers will work together to make the brand convincing for both humans and algorithms.

We can expect:

• The emergence of AEO industry standards (like the first SEO guides in the 2010s).
• Integration of AEO metrics into Google Analytics and other analytics systems.
• Growth of specialized agencies offering “AI Overview optimization” just as they once sold SEO.

In a few years, we’ll stop contrasting SEO and AEO. There will be one unified visibility strategy, with AEO at its core. — Rand Fishkin, SparkToro.

The future of AEO in 2025–2026 is clear: generative search engines will become the standard, old metrics will fade, and new ones — such as Share of Answers — will take center stage. Businesses must act now: adapt content, implement structured data, and strengthen digital reputation. Those who move first will secure their presence in AI answer blocks for years to come.

In other words, AEO is not a fad or a passing trend. It is the new infrastructure of digital marketing, one that will determine over the next two years who remains visible to customers — and who disappears from the internet map.

Conclusion: AEO as the New Standard of Digital Visibility

Answer Engine Optimization is no longer an experiment — it is becoming a core part of business strategy. The user experience has shifted: people now expect to receive answers directly in search, not sift through dozens of links. If a brand does not appear in those answers, it loses a critical touchpoint with its audience.

Companies that are already adapting to AEO — creating structured content, implementing microdata, investing in expertise and reputation — will come out ahead. They will become trusted sources for generative engines and earn customer confidence at the very moment when first impressions are formed.

In other words, AEO is not an addition to SEO, but its new form. In 2025–2026, a brand’s ability to “be in the answers” will become the defining criterion of digital success.
