SEO vs AEO vs GEO: What Each One Means and Where to Start

A year or two ago a marketing plan had one line for search. Now proposals arrive with three: SEO, AEO and GEO, often priced separately. Business owners ask us whether they need all three, whether SEO is finished, and what any of it means for the enquiries they get. The short answer is that these are not three projects. They are three things a search result can do with your website, and most of the work overlaps.

This guide explains each one in plain terms, shows where they differ, and gives an order of work. It applies whether your buyers are in Dubai, Riyadh, London, Berlin or Karachi, and we point out where the markets differ.

The short version

SEO: still the foundation

Search engine optimisation is the work of getting pages crawled, indexed and ranked. It has not been replaced, because the AI products sit on top of it. Google's AI Overviews and AI Mode draw on Google's own index. ChatGPT search uses third-party search providers alongside OpenAI's own crawler, and Bing has been one of the main ones. Perplexity runs its own crawler and index. If a page cannot be crawled, or loads its text only after JavaScript runs, none of these systems can use it.

The basics have not changed much: a site that loads quickly on a phone, one clear topic per page, titles and headings that say what the page is about, internal links that connect related pages, and links from other sites that vouch for yours. What has changed is how much weak pages cost you. A thin page that ranked tenth used to get a trickle of clicks. Now it is rarely chosen as a source by anything.

AEO: being the passage that gets quoted

Answer engine optimisation is about the shape of the page. When someone asks a question, the search engine looks for a passage it can lift as it is: a two-sentence definition, a short list of steps, a table that compares options. Pages that bury the answer under three paragraphs of background are passed over for pages that give it straight away.

• Put the answer to the page's main question in the first 40 to 60 words, written so it still makes sense if it is quoted alone.
• Use headings that are the questions people ask, such as "How long does an ERP project take?", rather than labels like "Timelines".
• Put comparisons in tables and procedures in numbered steps. Both are lifted almost word for word.
• Be specific: a price range, a number of weeks, a named city, a named regulation. Vague sentences are not quoted.
• Add structured data that matches what is visibly on the page: Organization, Article, Product or Service, and FAQ where the page genuinely has questions and answers.

GEO: being the name the assistant gives

Generative engine optimisation deals with a different situation. When someone asks ChatGPT "which companies in Riyadh build custom CRM software?", the assistant does not return a page. It writes a short answer and names a few businesses, sometimes with links to its sources. To be one of those names, the assistant has to find you, understand clearly what you do and where, and see that other sources agree.

That last part is what makes GEO different. Your own website says you are good; assistants give more weight to directories, review platforms, comparison articles, industry press and discussions that mention you independently. A research team that coined the term, in the paper GEO: Generative Engine Optimization, found that adding citations to sources, quotations and statistics to a page raised its visibility in generative answers by up to about 40% in their tests. Those were controlled experiments, not a guarantee, but the direction matches what we see: specific, sourced writing gets used.

Where they overlap, and where they pull apart

All three reward the same habits: accurate information, clear structure, a site that loads properly and a business that is easy to identify. Write one excellent page per customer question and you have done most of the SEO and AEO work at once.

They pull apart in two places. First, SEO rewards a page, while GEO rewards a brand. You can rank well and still never be named by an assistant if nobody else mentions you. Second, AEO can reduce clicks. If the answer is shown in full on the results page, some people never visit. That is why measuring only traffic gives a misleading picture. A page can lose clicks while the business gains enquiries from people who saw its name in an answer.

How the three play out in different markets

• Gulf (UAE, Saudi Arabia, Qatar): buyers search in both English and Arabic, and good Arabic business content is still scarce. A well-written Arabic page often has less to compete with than its English twin. See our guide to Arabic SEO in the UAE and Saudi Arabia.
• Europe and the UK: every language is a separate competition with its own keywords, and assistants tend to answer from sources in the user's language. Consent rules also leave gaps in analytics data. See multilingual SEO for Europe.
• Pakistan and South Asia: search is overwhelmingly on mobile, many queries mix English with Roman Urdu, and local results lean on Google Business Profile and reviews. See local SEO in Pakistan.

What to do first

How to measure each one

Do you need three agencies?

No. A website built properly, with clean code, fast pages, clear structure and answer-first writing, covers most of SEO and AEO by itself. GEO is ongoing work on reputation: reviews, listings, client references and mentions in the press. Be wary of anyone who guarantees placement in ChatGPT or AI Overviews. Nobody controls what an assistant says in its organic answers, and anyone promising otherwise is selling something they cannot deliver.

If your website is the weak link, our web development work builds the SEO and AEO layer in from the first day: server-rendered pages, structured data, fast mobile loading and a content structure built around your buyers' questions. Tell us about your site and we will tell you honestly which of the three needs work first.
