Search engines have evolved from simple web page indexes to intelligent systems capable of understanding and answering questions. In 2015, Google showed direct answers for only 4% of queries. By 2025, this figure had grown to 48%, and for informational queries, it reached 76%. Users no longer want to search for answers among dozens of links — they want specific information here and now.
Answer Engine Optimization (AEO) — This is content optimisation for direct responses from search engines and voice assistants. Unlike SEO, where the goal is to bring the user to the website, AEO aims to provide an answer directly in the search results. According to Semrush, websites in the zero position receive 35% more clicks than the first organic position.
The voice search market is growing by 25% annually. In Ukraine, 31% of internet users regularly use voice assistants to search for information. This creates new opportunities for businesses willing to adapt their content to the changing needs of their audience.
AEO is a strategy for creating content that is optimised for direct display in search engines in the form of highlighted answers. The main task is to provide the most accurate and structured answer to a specific user question in the shortest possible time.
The AEO philosophy is based on the understanding that 65% of search queries are interrogative or imply a search for specific information. Users formulate queries in the form of complete sentences: "how to cook borscht without meat", "how much does it cost to develop a website in Kyiv", "when is the best time to plant tomatoes in Ukraine". The average length of a voice query is 4.2 words, compared to 2.3 words in text search.
Answer systems work by extracting the most relevant information from indexed content. Google uses the Passage Ranking algorithm, which can highlight a specific paragraph from a long article if it accurately answers the question. Microsoft Bing uses Intelligent Answers technology, which processes over 100 million sources to generate accurate answers.
Algorithms for selecting content for direct answers analyse three key factors: relevance (85% or higher match with the query), structure (clear information hierarchy) and source authority (domain rating of 40 or higher).
Natural language processing plays a critical role in AEO. Google's BERT model processes 512 tokens of context at a time, understanding the relationships between words in a sentence. This allows the system to distinguish between queries for "Bank Dnipro" (a financial institution) and "Dnipro Riverbank" (a geographical feature), returning relevant responses.
Ranking factors for featured snippets include: exact match to search intent (35% weight), optimal answer length of 40-60 words (25% weight), presence of Schema.org structured data (20% weight), freshness of content for time-sensitive queries (weight 20%). Pages with properly marked FAQs are 82% more likely to appear in featured answers.
Paragraph snippets account for 82% of all featured snippets. The optimal length is 45-55 words containing a direct answer to the question. For example, for the query "what is blockchain," Google will highlight the definition: "Blockchain is a distributed database that stores information in the form of sequential blocks protected by cryptography."
Bullet points account for 10.8% and work best for step-by-step instructions or lists. The ideal number of points is between 5 and 8. Search engines can combine points from different parts of an article if they are logically related.
Table snippets account for 7.2% and are effective for comparisons, prices, and specifications. Google can reformat data from text into a table if the information is structured appropriately. The maximum size of the displayed table is 3 columns and 9 rows.
Knowledge Graph generates instant answers for 16% of queries using verified data sources. To be included in Knowledge Graph, you need to have Organization, Person, or Product markup with at least 7 mandatory fields filled in.

SEO focuses on attracting maximum traffic through high positions in organic search results. Success is measured by the number of clicks, where the first position receives 28.5% of clicks, the second — 15.7%, and the third — 11%. The business model is based on converting this traffic into leads or sales.
AEO works with the concept of "zero click" — providing an answer without the need to visit the website. Paradoxically, the absence of a click can be a positive result: Moz research shows that brands that regularly appear in featured snippets have 23% higher brand recall even without direct visits.
The impact on business metrics is radically different. While the main KPIs in SEO are organic traffic and conversions, AEO measures featured snippet share (the percentage of queries where the brand appears in direct answers) and voice search visibility. Companies with a high featured snippet share report a 15-20% increase in direct traffic due to increased brand awareness.
The content structure for AEO requires an "inverted pyramid" — the answer in the first sentence, followed by explanations and details. SEO text can gradually lead up to the main idea, while AEO content must respond immediately. The optimal structure is: definition (1 sentence) + explanation (2-3 sentences) + examples or details.
Micro-markup is becoming critically important. While basic Article markup is sufficient for SEO, AEO requires specific types: FAQPage (increases chances by 70%), HowTo (for instructions), QAPage (for question-and-answer pages). Correct speakable markup tells voice assistants which parts of the content are suitable for voice output.
Content length works differently. SEO prefers comprehensive guides of 2,000 words or more for maximum coverage of a topic. AEO requires a modular approach: each section should be a self-contained answer to a specific question within 50-75 words, with the entire page containing 20-30 such modules.
Zero-click searches have grown from 25% in 2017 to 65% in 2025 for informational queries. Users get answers to questions about the weather, currency rates, definitions, and facts without having to leave the search results page. This fundamentally changes the user journey from "search → click → read → answer" to "search → answer".
The customer journey is transforming from linear to point-of-contact interaction. Instead of sequentially exploring a website, users receive micro-interactions through featured snippets. A brand can respond to dozens of user questions without bringing them to the website, but rather by forming an expert image.
New interaction models include voice commerce (12% of users made purchases via voice assistants), instant answers in messengers (45% year-on-year growth) and proactive assistance, where systems offer answers before the user has finished typing their question.
The optimal length of a paragraph snippet is 42-58 words or 285-375 characters. A study of 10 million featured snippets showed that 90% of successful answers begin with a rephrasing of the question and contain key information in the first two sentences.
Structural requirements include using simple sentences (average length 15-20 words), avoiding complex terms without explanation, and including numerical data. Snippets with specific figures are selected 38% more often. For example, "The average salary for a programmer in Kyiv is $2,500" works better than "Programmers in Kyiv earn well."
Examples of successful featured snippets demonstrate clear patterns. Definitions begin with "X is...", instructions use numbered steps, and comparisons present information in the format "unlike Y, X has...". Ukrainian websites that follow these patterns increased their appearance in featured snippets by 120% in 2024.
Voice queries are characterised by conversational phrasing and greater length. 70% of voice queries contain question words (what, how, where, when, why). The average voice query in the Ukrainian segment contains 5-7 words, compared to 2-3 words in text search.
Conversational content requires natural language and direct answers. Instead of "Website optimisation Kyiv price," the user will ask, "How much does website optimisation cost in Kyiv?" The content should respond to this exact wording, using complete sentences and conversational constructions.
Local context is critical for voice search — 58% of queries have a local component. "Where is the nearest pharmacy?", "What will the weather be like tomorrow in Kharkiv?", "Is Nova Poshta open on Sundays?" require accurate geolocation information and up-to-date data on operating hours.
FAQ markup increases visibility in search results by 82% and allows you to take up more space in the results. The optimal number of questions on a page is 5-10, each answer should be self-sufficient and contain 50-150 words. Google can show up to 4 questions at a time from a single source.
How-to markup works for step-by-step instructions and increases CTR by 28%. Required elements: total execution time, list of necessary materials, step-by-step instructions with time for each step. Images for each step increase the likelihood of display by 45%.
Q&A formats are effective for technical support and educational content. The "question-answer-additional resources" structure allows you to cover a wide range of queries. Pages with 20+ high-quality Q&As receive an average of 3.5 featured snippets versus 0.7 for regular pages.

Modern search engines use advanced language models to understand queries. BERT (Bidirectional Encoder Representations from Transformers) processes 110 million parameters and understands the context on both sides of each word. This allows it to distinguish between queries such as "apple company" and "apple fruit" with 94% accuracy.
Google's Multitask Unified Model (MUM) is 1,000 times more powerful than BERT and works with 75 languages simultaneously. It understands information in text, images, and videos, which is critical for multimodal search. Query processing time has been reduced from 0.8 seconds to 0.2 seconds, while intent understanding accuracy has increased by 40%.
Semantic analysis identifies not only keywords, but also relationships between concepts. The system recognises that "buy an iPhone in Kyiv" and "where to buy an iPhone in the capital" are identical in meaning. Semantic matching accuracy reaches 87% for Ukrainian, compared to 93% for English.
Google's Knowledge Graph contains information about 8 billion entities and 800 billion facts about them. Each entity has a unique identifier and links to other objects. For example, "Taras Shevchenko" is linked to 147 other entities: works, places, dates, people.
To be included in the Knowledge Graph, Ukrainian companies must have structured data in JSON-LD format with at least 12 mandatory fields: name, address, telephone number, opening hours, website, social profiles, and registration details. Having a listing on Google My Business increases the chances by 73%.
E-A-T (Expertise, Authoritativeness, Trustworthiness) in the context of AEO is measured by specific signals. Expertise is confirmed by the presence of an author with a verified profile (30% influence), citations in authoritative sources (25%), relevance of information (20%), and the presence of sources and references (25%). Pages with high E-A-T appear in featured snippets 2.8 times more often.
Mobile-first indexing directly affects AEO — 63% of featured snippets are taken from the mobile version of the website. Critical factors: loading speed less than 2.5 seconds (Core Web Vitals), font size at least 16px, interactive elements no less than 48x48px, no horizontal scrolling.
Speakable markup indicates the optimal fragments for voice assistants to read aloud. The ideal length is 20-30 words or 2-3 seconds of audio. Content should be written in a conversational style with simple sentences. Using speakable increases the likelihood of voice assistants reading aloud by 215%.
Localisation is critical for voice search — 76% of queries contain local markers ("nearby", "in Odessa", "closest"). Geolocation accuracy must be within 100 metres for urban queries. The relevance of information about operating hours affects ranking — outdated data reduces impressions by 45%.
Impressions take on a new meaning in AEO. While in traditional SEO, an impression means a display in search results, in AEO it means the display of your content as a direct answer. A featured snippet impression is 8.5 times more valuable than a regular display, as it occupies 23% of the visible screen area compared to 2.7% for a regular result.
Position zero tracking requires specialised tools. Standard positions 1-10 are supplemented by position 0 for featured snippets, position V for voice response, and position K for Knowledge Panel. Companies that track these positions find that they lose up to 35% of visibility when using only classic metrics.
Share of voice in featured snippets is calculated as the percentage of queries in a niche where the brand appears in direct answers. Market leaders achieve a 25-30% share of voice in their categories. For comparison: the top 1 in organic search only gives an 8-10% share of voice for the same queries.
Featured snippet ownership rate shows the percentage of targeted queries where your content is selected for a direct answer. The average rate is 3-5% for general topics and 15-20% for highly specialised niches. Ukrainian IT companies achieve a 35% ownership rate for queries about local technologies and solutions.
Voice search visibility is measured by the percentage of voice queries where the assistant reads your content aloud. The current average is 2.3% for Ukrainian-language content versus 5.7% for English-language content. The difference is explained by the smaller amount of optimised content in Ukrainian.
Answer box appearance frequency tracks how often different types of your content appear in answers: paragraphs (45%), lists (30%), tables (15%), videos (10%). Diversifying formats increases the overall appearance frequency by 67%.
Brand awareness through zero-click presence grows non-linearly. Brands that appear in featured snippets 50+ times a day see a 34% increase in direct traffic and a 56% increase in brand queries within 6 months. At the same time, organic traffic may decrease by 15-20%.
Attribution models need to be revised. The classic last-click model does not take into account the impact of zero-click impressions. Companies are implementing multi-touch attribution with a weight of 0.3 for featured snippet impressions, 0.5 for voice answers, and 1.0 for clicks. This shows the real contribution of AEO to conversions — up to 27% for B2B and 18% for B2C.
The ROI of an AEO strategy is measured comprehensively. Direct ROI (increased traffic and conversions) is 150-200% in the first year. Indirect ROI (improved recognition, trust, expertise) reaches 400-500% in 2-3 years. Investments in AEO pay off on average in 8-10 months, compared to 12-15 months for classic SEO.
