Answer Engine Optimisation (AEO) is changing what marketing teams need to deliver. If your organisation is not appearing in AI-generated answers, you are invisible to a growing share of your audience.
Check your AI visibilityFor years, digital marketing has centred on two things: getting found on Google, and converting visitors once they arrive. AEO introduces a third challenge - getting cited by AI assistants before a user ever visits a website.
When someone asks ChatGPT which charity does the best work in food poverty, or asks Perplexity which school in their area has the strongest STEM programme, the AI produces a confident answer. It draws on everything it has indexed about each organisation. If your content is thin, inconsistent, or structurally unclear, you will not appear - even if your work is genuinely excellent.
AEO (Answer Engine Optimisation) is the discipline of making sure AI assistants can find, understand, and confidently recommend your organisation. It sits alongside traditional SEO and PR, but requires its own thinking.
The marketing teams that move earliest on AEO will establish AI presence while their competitors are still relying on Google ranking alone. This is a rare window - the equivalent of being an early mover in SEO in the early 2000s.
Product Hunt, one of the world's largest product discovery platforms, ran a controlled experiment to understand why AI assistants were rarely citing their pages - despite having strong SEO and millions of reviews.
They used an AI visibility tracking tool to measure citation rates across ChatGPT and Google AI, then made a series of targeted changes. The results were striking:
The lesson is that AI visibility is not the automatic result of having good content. It has to be actively structured, monitored, and iterated - exactly as SEO performance had to be managed a decade ago.
AEO is not a bolt-on. It changes how marketing teams should think about content, terminology, and measurement. Here is what the evidence points to:
AI assistants retrieve content using the same vocabulary people use when asking questions. If your website describes your services in specialist jargon while your audience asks in plain language, you will not be cited. Audit whether your page titles and headings match common query phrasing.
The Product Hunt experiment found that FAQ sections significantly increased citation rates across multiple AI platforms. AI assistants are built to answer questions - pages that are already structured as questions and answers are naturally easier for them to use. Every key page should have an FAQ section.
Schema.org markup (JSON-LD) gives AI systems explicit signals about what your content is and who you are. Organisation, FAQ, and Article schema are the most valuable for AEO purposes. This is often overlooked by marketing teams and handled poorly by generalist web developers.
Many organisations are unknowingly blocking AI crawlers through their robots.txt file - sometimes because a developer added a blanket block, sometimes because of a Cloudflare configuration. If PerplexityBot or GPTBot is blocked, those platforms cannot index your content regardless of how well it is written. This is one of the most overlooked causes of poor AI visibility.
Traditional marketing metrics do not capture AI visibility. A competitor may be appearing in thousands of AI-generated answers about your sector while your web traffic looks stable. You need to know how often each major AI platform is citing your organisation - and whether that is improving over time.
These three disciplines are complementary, not competing:
Helps your pages rank in Google and other search engines. Still essential - AI platforms use search to research on users' behalf, so strong SEO is a precondition for good AEO.
Creates third-party credibility signals - media coverage, expert quotes, mentions in respected publications. These are among the most powerful signals AI systems use to evaluate authority.
Ensures your website is technically accessible to AI crawlers, structured so AI systems can understand it, and uses terminology that matches how people ask questions. Sits on top of SEO and PR.
One finding from the Product Hunt experiment that marketing teams should take seriously: AI citation patterns shift significantly when model updates are released. A source that was being cited consistently can drop overnight. A new source can suddenly appear.
This means AEO cannot be a one-time project. Citation rate needs to be monitored the way search ranking is monitored - on an ongoing basis, across multiple AI platforms. A quarterly scan is a reasonable minimum for most organisations; monthly is better for those in competitive sectors.
Seen-by.ai tests your visibility across all four major platforms simultaneously, so you get a complete picture rather than a partial one - and you can run it again whenever a model update might have changed your standing.
The first step is knowing your current AI visibility across all four platforms. A full competitive intelligence scan takes a few minutes and costs £4.99.
