With answer engines such as Google's AI Overviews, ChatGPT, Gemini, Perplexity and Copilot, people increasingly get a synthesised answer before, or instead of, a list of links. SEO aims to rank well in search results; AEO (Answer Engine Optimisation) aims to provide clear answers that can be used directly; GEO (Generative Engine Optimisation) aims to make content easy for generative systems to understand, verify and cite. The three overlap heavily and rest on the same foundation: a technically accessible site with useful, accurate and trustworthy content.
Let us be explicit from the start: nobody can guarantee that your content will be cited by ChatGPT, Gemini, Perplexity or AI Overviews. How these systems select sources is not publicly documented in detail, changes frequently and differs between products. Anyone promising guaranteed citations is not being honest. What you can do is work on the factors you control, which improve your chances of being found, understood and reused.
Three acronyms, one foundation
SEO: getting found and ranked
Search engine optimisation is still the base layer. Answer engines rely largely on search indexes and on pages that crawlers can reach. Google's Search Central documentation states that standard SEO best practices also apply to its AI features, with no special additional technical requirements. A page that is not indexed, loads slowly or is accidentally blocked in robots.txt is unlikely to be picked up anywhere.
AEO: answering directly
AEO means structuring content so that a specific question finds a specific, easy-to-locate answer: the answer in the opening lines, headings phrased as real questions, FAQs, definitions and step lists. It continues the work many sites already did for featured snippets and voice search.
GEO: being understood and cited by generative AI
GEO takes this further. A generative system assembles an answer from several sources and needs content that is clear, factual, consistent and attributable: who is speaking, on what basis, with what evidence. Vague, promotional or contradictory pages are hard to use.
What changes and what does not
| Aspect | Traditional search | Answer engines |
|---|---|---|
| Result format | List of links and snippets | Synthesised answer, sometimes with source links |
| Unit of value | The page | The passage, the answer, the verifiable fact |
| Click to your site | Main goal | Not guaranteed; some needs are met without a click |
| Measurement | Rankings, clicks, impressions (Search Console) | Partial; few reliable tools to track citations |
| Technical base | Crawling, indexing, performance | Same, plus access for each provider's crawlers |
| Trust signals | Quality, relevance, links | Same, with clarity and consistency weighing more |
What does not change: content has to help a real person. Manipulative tactics such as mass-produced low-value pages, duplicate content or keyword stuffing break Google's spam policies and deliver nothing lasting.
Practices you can control
1. Technical foundations
- Check indexing and coverage in Google Search Console and Bing Webmaster Tools.
- Review robots.txt: entire sections are often blocked by mistake. Each AI provider documents its own crawlers; decide deliberately which ones to allow.
- Serve your main content as HTML rather than relying solely on client-side JavaScript.
- Look after speed, mobile usability and an up-to-date XML sitemap.
2. Clear answers up front
For each important page, identify the main question and answer it within the first two paragraphs. Then expand with context, details, examples and limits. This inverted-pyramid structure serves both hurried readers and systems that extract passages.
3. Explicit headings and structure
Use H2 and H3 headings that genuinely describe each section, lists for steps and tables for comparisons. Each passage should make sense on its own, without relying on "as mentioned above".
4. Precise, sourced facts
Cite official sources, date your content and keep it updated. Avoid figures nobody can verify. Precise, attributed information is easier to reuse than broad claims.
5. A clear identity
Make it obvious who is publishing: an About page, contact details, address, author or responsible team. Business information should match everywhere: website, Google Business Profile, social profiles and directories.
6. Structured data
Schema.org markup (Organisation, LocalBusiness, Article, FAQPage, Course, BreadcrumbList and so on) helps search engines interpret a page. It guarantees no particular display and must match the visible content exactly.
7. Content only you can write
Generative engines summarise generic material easily. The value lies in your specific experience: how a process actually works in Tunisia, which local constraints apply, which mistakes you see repeatedly. A guide to exporting from Sfax, tourism seasonality in Sousse or local online payment options offers information generic content does not.
Example: a services SME in Sousse
Picture a B2B services company whose service pages are short and purely promotional. A sensible plan would be to:
- confirm in Search Console that every page is indexed;
- rewrite each service page to answer "what it is, who it is for, how it works and how long it takes" first;
- add an FAQ built from the questions customers actually ask by phone or email;
- publish a few in-depth guides on topics where the team has real expertise;
- align contact details across the site and Google Business Profile;
- add matching structured data.
None of these steps guarantees a citation in an answer engine. All of them improve the site for visitors and for traditional search.
Common mistakes to avoid
- Mass-publishing generic AI-written text with no expertise or review: it adds nothing the engines cannot already summarise.
- Burying the answer behind a long introduction or a mandatory form.
- Leaving contradictory information across pages, such as different opening hours or prices.
- Adding structured data that does not match the visible content, which goes against Google's guidelines.
- Chasing every new acronym instead of strengthening the fundamentals.
- Ignoring local context: a Tunisian audience searches in French, Arabic and sometimes English, so check which language your customers actually use for each topic before deciding what to publish.
Measure with realistic expectations
Measurement is the weak spot today. Search Console folds data from Google's AI features into overall web performance rather than offering a detailed separate report. For other answer engines, referral traffic in your analytics tool, for example GA4, gives a partial picture. Third-party tools offer citation tracking, but they rely on samples of queries, so treat them as trends rather than facts.
Above all, track what matters to the business: enquiries, calls, meetings booked, and the answer to "how did you hear about us?" asked of every new customer.
Prerequisites and limits
- No guarantee of citations or rankings, whatever the budget.
- Time: foundational work shows results over months, not days.
- Editorial resources: accurate content needs input from subject-matter experts.
- A moving target: answer-engine interfaces and policies keep changing, so ongoing monitoring is required.
- AI-generated content is not banned as such, but it must be reviewed, fact-checked and genuinely useful.
Bottom line
SEO, AEO and GEO are not three separate projects but three angles on the same work: making a site accessible, clear, reliable and useful. Those controllable factors are where Astronet Agency supports businesses, through training and advisory work.
