What is answer engine optimisation, and how is it different from SEO?
When the answer arrives before the click
Answer engine optimisation (AEO) is the practice of shaping your content so search engines and AI assistants can lift it as a direct answer, in featured snippets, Google AI Overviews, voice assistants and chat tools. SEO aims to rank a page and earn the click; AEO aims to be the quoted answer itself. For Danish businesses the two share most foundations but measure success differently.
In this explainer
What answer engine optimisation means
An answer engine is any system that responds to a question with an answer rather than a list of links. Google has been one for years in a small way: featured snippets, the “People also ask” boxes and knowledge panels all answer directly on the results page. Voice assistants such as Siri and Google Assistant read out a single answer. More recently, Google’s AI Overviews and chat tools such as ChatGPT, Gemini, Copilot and Perplexity write a summary and cite a handful of sources.
Answer engine optimisation is the work of making your content the source those systems choose. It is not a separate discipline invented from nothing. It grew out of the techniques people used to win featured snippets, and it has become more important as more searches end with an answer on the screen and no click at all.
You will also see the term GEO, generative engine optimisation. People use the two terms in overlapping ways. On our site, AEO covers being the direct answer to specific questions, while GEO covers how AI models understand and recommend your business more broadly.
How AEO differs from SEO
Traditional SEO and AEO share a lot, but they aim at different moments and reward slightly different writing.
| SEO | AEO | |
|---|---|---|
| Main goal | Rank a page and win the click | Be quoted or summarised as the answer |
| Typical query | Short keywords, such as “wedding venue Copenhagen” | Full questions, such as “how much does a wedding venue in Copenhagen cost?” |
| Unit of content | The whole page | A passage, list or table within the page |
| Where it shows | The ten blue links and map pack | Snippets, AI Overviews, voice, chat assistants |
| Main measure | Rankings, organic clicks, conversions | Appearances, citations, branded demand |
The biggest practical difference is the unit. SEO thinks about pages; AEO thinks about passages. A page can rank well and still never be quoted, because the answer is buried in the fourth paragraph after a long introduction. Equally, a single clear paragraph on a modest page can be lifted into an AI Overview.
The SEO foundations AEO depends on
It is tempting to treat AEO as a shortcut, but answer engines mostly draw on the same index and the same quality signals as search. Before anything else, a site needs:
- Pages that can be crawled and indexed, with no accidental blocks in robots.txt or noindex tags.
- Fast, mobile-friendly pages; Google uses mobile-first indexing.
- A clear site structure, so each topic has one obvious page.
- Signs of trust: who wrote the content, who the business is, how to contact it, and links or mentions from other credible sites.
- Accurate, up-to-date information, especially prices, opening hours and service areas.
Google has said that pages appearing in AI Overviews must be indexed and eligible to show in normal search, and that the usual SEO best practices apply. If those basics are weak, start with SEO, because AEO work will not hold on a shaky site.
Writing content that answer engines can lift
Once the foundations are sound, the writing itself makes the difference. A few habits help a great deal:
- Use the question as the heading. Phrase headings the way people actually ask, in their own words, including Danish phrasing where you write in Danish.
- Answer in the first sentence. Give the direct answer straight under the heading, in one or two sentences that make sense on their own, then explain.
- Keep answers self-contained. Avoid “as mentioned above”. A lifted passage has no “above”.
- Use lists and tables for steps and comparisons. They are easy for machines to parse and for people to scan.
- Be specific. Name places, numbers, time frames and conditions. Vague answers are rarely chosen when a specific one exists.
- State who you are. Name the business, the location and the author, so the source is clear when quoted.
Structured data in schema.org format, such as Organization, LocalBusiness, Article and FAQPage, helps machines understand what a page is about. Google limited FAQ rich results in 2023 to a narrow group of authoritative sites, so FAQ markup rarely produces the old expandable results now, but it still describes the content clearly. We build pages with this structure in our citation-ready pages work.
Finding the questions worth answering
AEO starts with the questions your customers actually ask. Good sources include:
- The “People also ask” boxes and autocomplete suggestions in Google, searched in both Danish and English.
- Search Console queries that are phrased as questions, filtered by words such as hvordan, hvad, hvor meget, how, what and cost.
- Questions your sales team, receptionist or customer service hear every week.
- Reviews, forums and community groups where people discuss your type of service.
- Asking the AI assistants themselves what they would tell someone looking for your service, and noting which sources they cite.
Prioritise questions that sit close to a buying decision, such as cost, timing, comparison and suitability, over general trivia. Being the quoted answer to “what is a DJ” does little for a business; being quoted for “how far ahead should I book a wedding DJ in Denmark” can bring real enquiries.
How to measure AEO when clicks go missing
Measuring AEO is harder than measuring SEO, and it is worth being honest about that. When an answer engine quotes you and the user is satisfied, there may be no visit at all. Google Search Console includes AI Overview appearances within its normal web search data, without separating them out, so you cannot see AEO performance in a single report.
A workable approach combines several signals:
- Regular manual checks of a fixed list of priority questions in Google, ChatGPT, Perplexity and Gemini, noting whether you appear and are cited.
- Impressions in Search Console for question-style queries, even when clicks are low.
- Referral traffic from chatgpt.com, perplexity.ai and similar sources in your analytics.
- Growth in branded searches and direct enquiries that mention finding you through an AI assistant.
Expect gradual change. Answer engines refresh and re-rank sources continually, and results for the same question can differ from one day or user to the next.
Where a Danish business should start
For most small and medium businesses, a sensible first step is to pick the ten to twenty questions that matter most commercially, check whether you already answer each one clearly on a single page, and fix the gaps. Rewrite the opening of each relevant page so it answers directly, add an FAQ section with genuinely useful answers, and make sure your company details are consistent everywhere they appear online.
A short order of work that suits most sites:
- Fix technical blockers so every important page is indexed.
- Choose one page per question and remove or merge pages that compete for the same answer.
- Rewrite headings and opening sentences so the answer comes first.
- Add FAQ sections, tables and lists where they genuinely help the reader.
- Add or tidy structured data for your organisation, location and articles.
- Recheck your priority questions every month and adjust.
That work also strengthens your normal search rankings, so it is rarely wasted. Search and answer engines are converging, and a page written to answer a real question clearly tends to serve both.
AEO in practice
Answer engines,
the follow-up questions
You need both, because AEO depends on SEO rather than replacing it. Answer engines such as Google AI Overviews mainly choose sources from pages that are already indexed, trusted and relevant, which is exactly what SEO builds. A page that does not rank at all is rarely quoted.
What AEO adds is a change in how content is written and structured: questions as headings, direct first sentences, self-contained passages and clear facts. In practice the two are best handled together, by the same people, in the same content plan. Treating AEO as a separate project with separate pages tends to create duplicate content and confuse both search engines and visitors about which page to use.
For some searches, yes, they can reduce clicks, particularly simple factual questions that the overview answers fully. Several independent studies have reported lower click-through rates on results pages where an AI Overview appears, though the size of the effect varies by query type and industry.
Searches with commercial intent behave differently. When people are choosing a supplier, booking a service or comparing options, they still tend to click through to check details and make contact. Being cited in the overview also puts your name in front of them at the moment of decision. The practical response is to focus on questions close to buying, make your pages worth the click, and measure enquiries rather than only visits.
Usually anywhere from a few weeks to a few months. First the search engine has to recrawl and reprocess the updated page, which can take days for frequently visited sites and longer for smaller ones. Then it has to decide that your passage answers the question better than the sources it currently uses.
Featured snippets and AI Overviews can change quickly once a page is reprocessed, while chat assistants that rely on their own indexes or training data may take longer to reflect new content. You can speed up discovery by submitting updated pages in Google Search Console and Bing Webmaster Tools and by linking to them from your other pages. Track a fixed set of questions monthly to see progress.
Yes, often more than for national brands, because local questions are specific and the competition is thinner. People ask assistants and search engines things like where to find a service in a particular area, what it costs or how far ahead to book. Few local competitors answer these questions clearly on their websites.
For a local business, AEO combines well with local SEO: an accurate Google Business Profile, consistent name, address and phone number across directories, and reviews that mention the service and area. Add clear answers to your most common customer questions on the relevant service pages, in Danish and in English if you serve international customers in Copenhagen, and you cover both maps and answers.
