What is AEO and how do you optimize for AI search engines

In 2025 Google started showing AI Overviews at the top of search results for more and more queries. At the same time millions of people use ChatGPT and Perplexity as the first place to look something up. The result: people get an answer without ever clicking a link. AEO is the response to that shift.

What AEO actually is

AEO stands for Answer Engine Optimization. The goal is for an AI system to use and cite your content when it answers a question. Not to appear in a list, but to be the answer.

The difference with classic SEO sits in the outcome:

• SEO wants your page at position 1 in a list of ten results.
• AEO wants an AI to fold your information into a direct answer and name you as the source.

An AI system does not click, it reads. It picks fragments that answer a question completely and reliably. That is what you optimize for.

How AI search engines pick content

Models like the ones behind ChatGPT and Perplexity weigh three things heavily: clarity, structure and trust. A wall of text with no heading or answer is rarely cited. A page that answers a question in the first paragraph is.

The practical rule: write so an AI can copy your answer without having to invent anything. Give the fact, the number, the step.

This is exactly why we begin every blog post with a "quick answer" block of 50 to 100 words. That is no accident, that is AEO in action: the answer is ready for both the reader and the machine.

Five concrete AEO techniques

These steps we apply to our own content and to that of clients:

• Answer the question directly. Put the core answer in the first two sentences of a section, then the explanation.
• Use question-driven headings. An H2 like "What does a webshop cost?" matches how people ask an AI.
• Add structured data. FAQ schema and Article schema help machines understand your content.
• Make content citable. Short, self-contained paragraphs with facts, numbers and sources work better than long arguments.
• Build authority. AI trusts sources that are mentioned elsewhere. Mentions, reviews and consistent business data count.

FAQ sections are worth gold

A good FAQ at the end of a page is one of the strongest AEO instruments. Every question-answer pair is a bite-sized fragment an AI can lift directly. Keep answers between 40 and 80 words and answer exactly what is asked.

SEO and AEO work together

AEO does not replace SEO. An AI system draws largely from pages that also rank well in classic search results. Fast load times, a crawlable structure and relevant content remain the basis. So read our SEO approach too, because without that foundation AEO has no ground to stand on.

What changes is the unit of measure. Alongside positions and clicks you now also look at: are you cited in AI Overviews, does Perplexity name you as a source, does your brand name appear in ChatGPT answers. At NedDev we measure this for clients as part of the SEO and AEO service, because the traffic it produces often converts higher: people who arrive through an AI recommendation are already convinced.

The practical conclusion: keep making good content, but structure it so both a human and a machine find the answer at a glance.

The mistakes that cost you visibility

AEO is relatively new, so plenty of assumptions circulate that backfire. These three we see most often:

• Thinking it is a trick. There is no button to "get into ChatGPT". AI cites content that is factually correct, clear and authoritative. Structuring bad content well does not help.
• Dropping SEO for AEO. AI systems draw largely from pages that also rank well organically. Neglect your SEO and you disappear from the AI answers too.
• Hiding everything behind JavaScript. If your content only appears after heavy client-side rendering, crawlers and AI bots often cannot read it. Server-side rendering or static generation solves this.

Measure what counts in the AI era

The classic metrics stay, but new ones arrive. Alongside positions and clicks, track these too:

• Citations: does your brand or site appear as a source in AI Overviews and Perplexity answers.
• Referral traffic: check your analytics for visitors from domains like perplexity.ai and chatgpt.com.
• Brand mentions: does an AI name your company when someone asks a question in your field.

This traffic is small in volume but high in quality. Someone who reaches you through an AI recommendation is often already convinced and converts better than the average searcher.

Which questions you optimize for

Not every search ends in an AI answer. People use AI mainly for explanation, comparison and advice, less for pure navigation. So aim your AEO at the right types of questions:

• "What is" and "how does it work": explanatory questions an AI happily lifts a clear answer from.
• "What does it cost" and "how much": questions with a concrete, citable number as the answer.
• "Difference between X and Y": comparisons where a structured overview is worth gold.
• "Best way to": advice questions where your experience and concrete steps count.

For this kind of question you write content that gives the answer directly and completely. A table, a list or a short definition at the top works better than a narrative intro.
