A practical comparison of traditional search optimisation and answer-engine work—where the disciplines genuinely differ, where they overlap, and which actions should be funded first.
What is SEO?
Search engine optimization improves a website’s ability to be crawled, indexed, understood, ranked and chosen in organic search. It covers technical access, information architecture, content quality, internal links, external reputation, search appearance, user experience and measurement.
SEO is not limited to “ten blue links.” Modern Google Search includes product results, local results, images, video, featured snippets, AI Overviews and AI Mode. The surfaces evolve, but a page still needs to satisfy the relevant eligibility, quality and user requirements.
What is AEO?
Answer engine optimization is a marketing term for improving how accurately and visibly a brand, page or source appears when a system returns a direct or generated answer. Depending on the practitioner, AEO may include featured snippets, voice assistants, Google AI features, ChatGPT, Perplexity, Gemini Apps and other conversational products.
That broad usage is why the term can be confusing. Google does not describe AEO as a separate Google ranking system. Its 2026 guidance says that, from Google Search’s perspective, optimising for generative AI search is optimising for the search experience and therefore remains SEO. Outside Google, product-specific crawler controls, source behaviour and prompt-level monitoring may require additional operations.
AEO vs SEO: the useful difference
| Dimension | SEO programme | AEO / AI-search layer |
|---|---|---|
| Primary question | Can the right page be discovered, ranked and chosen? | Is the brand or source represented accurately in generated/direct answers? |
| Typical surfaces | Organic web, local, shopping, image, video and other search results | AI Overviews, AI Mode, ChatGPT Search, Perplexity and assistant answers |
| Research unit | Queries, intents, SERPs, landing pages and journeys | Prompts, follow-ups, answer contexts, sources and model/product conditions |
| Core deliverables | Technical fixes, intent-owned pages, internal links and authority development | Prompt sets, source-gap analysis, answer accuracy, citation/mention monitoring and corrections |
| Direct metrics | Impressions, rankings, clicks, CTR, organic conversions | AI-feature impressions, mention/recommendation rate, displayed sources and answer accuracy |
| Shared foundation | Accessible pages, useful original content, clear ownership, consistent facts, evidence and business measurement | |
The difference is operational rather than absolute. A good SEO page can be used in an AI answer; a useful answer-oriented page can also rank in traditional results. The work becomes harmful when teams create separate duplicate pages for every acronym or optimise an unexplained AI score instead of a customer decision.
Where AEO and SEO overlap
- Search intent: both start with the problem a real person needs to solve.
- Crawl and access: a product cannot retrieve a page it cannot access through its supported route.
- Useful content: original evidence, clear explanations and accurate claims serve users across surfaces.
- Information architecture: one strong intent owner and contextual internal links reduce duplication and ambiguity.
- Entity consistency: names, products, people, locations and policies should not contradict each other.
- Reputation and sources: credible independent coverage can help customers and systems verify a claim.
- Conversion: visibility has no business value unless the right audience can evaluate and contact or buy.
What changes when search returns an answer?
The customer may receive a synthesis, comparison or recommendation before visiting a site. That creates additional work that ordinary rank tracking does not fully capture:
- build branded and unbranded prompt samples from real buying decisions;
- record the product, model/mode, market, language, date and account conditions;
- separate a brand mention from a recommendation and a displayed link;
- verify whether the generated description is accurate, incomplete, stale or false;
- inspect which owned and third-party pages appear beside the answer;
- repeat comparable samples because generated answers can vary;
- connect AI visibility to branded search, referrals, assisted conversions and qualified leads.
This is an extension of search research and measurement—not evidence that classic SEO is obsolete.
What Google says about AEO and GEO
Google’s official generative AI Search guide says SEO best practices remain relevant because AI features use core Search ranking and quality systems. It also says website owners can ignore several widely marketed Google “AEO hacks”:
- Google Search does not require an
llms.txtfile or another special AI text file. - There is no required content “chunking” pattern or ideal AI word count.
- Content does not need to be rewritten in a special style only for AI systems.
- Inauthentic mentions are not a sustainable shortcut.
- Structured data is not required for generative AI Search and there is no special AI schema.
Google still recommends crawlable, indexed, people-first, non-commodity content; relevant images/video; accurate Merchant Center or Business Profile information; and structured data that matches visible content. Eligibility never guarantees crawling, indexing or selection.
Google Search, Gemini Apps and ChatGPT need separate controls
| Surface | Relevant access or measurement fact | Do not assume |
|---|---|---|
| Google AI Overviews / AI Mode | Uses Google Search systems; measure eligible properties in Search Console’s Generative AI report | That special schema, llms.txt or Google-Extended improves Search ranking |
| Gemini Apps | A separate product surface; Google-Extended affects Gemini Apps use but does not affect Google Search | That a Gemini app mention is a Search Console impression |
| ChatGPT Search | OpenAI says OAI-SearchBot access is needed for content to be included in summaries and snippets | That GPTBot and OAI-SearchBot serve the same purpose |
| Third-party AI tools | Require their own product, crawler and evidence checks | That a Google optimisation tactic automatically transfers unchanged |
Use the AI bot robots.txt guide before changing crawler policy. A broad “Allow every AI bot” block is not an optimisation strategy; access should match the organisation’s publishing and training preferences.
Should you prioritize AEO or SEO first?
| Current situation | First priority | Then add |
|---|---|---|
| Important pages are not indexed or technically unreliable | SEO access, canonical, rendering and quality fixes | AI-surface measurement after the pages are eligible |
| Organic visibility exists but the brand is absent from relevant AI answers | Prompt/source baseline and intent-gap analysis | Evidence-led page and external-source improvements |
| AI systems describe the company incorrectly | Fact and citation diagnosis | Owned/third-party corrections and repeat monitoring |
| Local or ecommerce facts are inconsistent | Business Profile, Merchant Center and canonical product/location data | Market-specific answer monitoring |
| Traffic exists but leads are weak | Intent and conversion-path work | AI visibility only for commercially relevant decisions |
| No reliable baseline exists | Measure Web Search, Google generative AI and selected assistants separately | Prioritise gaps by revenue risk and opportunity |
Most organisations should not allocate a fixed percentage to “SEO versus AEO.” Fund the bottleneck. A technically broken site needs technical and content fundamentals; an established brand with inaccurate AI descriptions needs source governance and monitoring.
A combined SEO and AEO workflow
- Define the business decision: which product, service, location or comparison should create a lead or sale?
- Map search and answer demand: combine Search Console, SERPs, sales questions, communities and prompt samples.
- Assign one intent owner: decide whether the service page, product page, guide, comparison or tool should rank and convert.
- Fix access and duplication: check status codes, canonical, rendering, internal links, robots policy and sitemap inclusion.
- Create non-commodity evidence: publish real process, examples, methodology, constraints, product facts or first-hand data.
- Clarify and connect facts: keep visible content, author/business identity and supported structured data consistent.
- Measure by surface: track Google Web, Google generative AI, assistant observations and business outcomes without blending them into one opaque score.
How to measure SEO and AEO without inventing ROI
| Layer | Measurements | Main limitation |
|---|---|---|
| Google Web Search | Queries, pages, impressions, clicks, CTR, average position | Does not isolate standalone assistant mentions |
| Google generative AI report | Impressions by page, country, device and date | Not a prompt-level Gemini Apps tracker |
| Assistant sample | Mention, recommendation, competitors, displayed links, accuracy | Results vary by prompt, model, market and time |
| Web analytics | Known referrals, engaged sessions and conversions | Many answer exposures create no attributable click |
| Business outcomes | Qualified leads, assisted revenue, branded demand and customer-reported discovery | Needs CRM and attribution discipline |
Do not promise a universal 2–8 week citation timeline, a 3–5× “hybrid lift” or a percentage of AI citation decisions explained by one signal. Establish a baseline, record the intervention and compare equivalent samples over a useful window.
Common AEO vs SEO mistakes
- Publishing duplicate acronym pages: separate SEO, AEO, GEO and LLMO pages often compete for the same user question.
- Confusing eligibility with selection: valid schema or crawler access never guarantees a citation.
- Using FAQPage as an AEO switch: markup must reflect visible content and Google limits FAQ rich-result visibility.
- Tracking one prompt once: a single generated answer is an observation, not a stable rank.
- Calling every related link a citation: product interfaces use different source and link conventions.
- Optimising a vendor score: require raw prompts, answers, dates, markets and collection methods.
- Ignoring conversion: a mention for an irrelevant prompt is not commercial success.
- Inventing case studies: label illustrative examples and publish real evidence only when it can be substantiated.
Use one search strategy, measured across several surfaces
The practical choice is not AEO or SEO. Build a reliable search foundation, add product-specific research and measurement where customers use answer engines, and prioritise the gaps that affect revenue or reputation. Maksut.net’s AI SEO and search visibility service connects technical SEO, intent ownership, source consistency, prompt monitoring and conversion measurement without selling unsupported citation guarantees.
AEO vs SEO FAQ
- What is the main difference between AEO and SEO?
SEO is the broader practice of earning visibility and business outcomes through search. AEO emphasises how a brand or source appears in direct and generated answers, adding prompt, source, accuracy and mention measurement.
- Is AEO just SEO with a new name?
For Google Search, Google says optimising for its generative AI features is still SEO. Across standalone assistants, AEO can describe additional product-specific access, prompt sampling, source analysis and answer-accuracy work.
- Does AEO replace SEO?
No. Useful, accessible and trustworthy pages remain the foundation. AEO adds answer-surface research and measurement; it does not remove technical, content, authority or conversion requirements.
- Should a new website invest in AEO or SEO first?
Start with customer intent, crawl/index eligibility, clear service or product pages and measurement. Add a small AI-answer baseline early, but do not divert the budget from critical foundations to speculative hacks.
- Does schema markup improve AEO?
Accurate structured data can support rich-result eligibility and consistent entity descriptions. Google says no special schema is required for generative AI Search, and markup does not guarantee an AI mention or citation.
- How long does AEO take?
There is no universal timeline. Crawling, indexing, external-source changes, model/product updates and prompt variability operate on different schedules. Record a baseline and compare equivalent samples instead of promising a fixed number of weeks.
