AEO vs GEO vs LLMO: the acronyms explained

AEO, GEO and LLMO are overlapping labels for the same job: making your business easy for AI systems to find, understand and quote correctly. The labels differ far more than the work does.

The terms

• AEO: answer engine optimization. Focus on being the source of a direct answer. See what is AEO.
• GEO: generative engine optimization. Focus on appearing in the responses of generative AI tools.
• LLMO: large language model optimization. Focus on being represented accurately by language models.
• AI search optimization, AIO and similar phrases are used loosely for the same idea.

Why the work is the same

Whatever the label, the steps barely change. Let legitimate crawlers in, serve readable HTML, keep your facts consistent, add structured data, publish clear answers, and build a real presence on sources assistants read, such as your Google Business Profile and respected directories.

Because the terminology is still settling, do not buy a service on the strength of an acronym. Ask what, specifically, will change on your site and listings.

How it connects to classic SEO

All of these sit on top of ordinary search fundamentals. A fast, clear, trustworthy site helps everywhere. See SEO vs AEO for how the two relate.

What to ignore

Be wary of guaranteed recommendations, hidden text aimed at AI systems and fabricated reviews. None of them last, and all of them damage your reputation. See good vs bad AI practices.

Which label should you use on your own site?

Use plain language customers would search, such as "show up in AI answers" or "AI search visibility". Use AEO, GEO or LLMO only when your audience already knows the term, and define it on first use. Whatever the label, the work list is the same; see what is AEO for the steps.

Why there are so many labels

Search has always collected acronyms. SEO is the long-standing one. When AI chat tools and AI summaries arrived, people needed words for the new work, and different writers coined different terms at roughly the same time. Some emphasize the answer, some the generative tool, some the language model underneath. None of them has been adopted by a standards body, and none is more correct than the others.

This matters because it affects what you read and what you are sold. Two articles may use different words for the same advice, and two vendors may use the same word for different services. Understanding that the vocabulary is unsettled is the best protection against being impressed by jargon. Our AEO overview uses the term we find most plain, but the steps in it apply under any of the labels.

How to read a pitch that uses these terms

If someone offers GEO, LLMO or AEO services, the acronym tells you very little. What tells you something is a specific list of changes. Useful questions to ask:

• What exactly will change on my website, listings and files?
• How will you check the result, and how often?
• Who owns the work if we stop?
• What do you not promise?

A trustworthy answer names real tasks, such as fixing crawler access, correcting inconsistent facts, adding structured data and writing honest pages, and admits that nobody controls what an AI says. Be wary of guaranteed placement, secret techniques and anything involving fake reviews or hidden text. Our guides on questions to ask an AI vendor and what to prepare before you talk to an AI consultant go further.

The work behind every label, as one checklist

• Access: make sure legitimate crawlers can reach your pages. See robots.txt for AI crawlers.
• Readability: serve key content as plain HTML text.
• Consistency: keep name, services, area, hours and contact details identical everywhere.
• Structure: label those facts with schema markup.
• Answers: write pages and FAQs that respond directly to real questions. See how to write FAQs that get quoted.
• Presence: maintain your Google Business Profile and respected directory listings.
• Checking: test a fixed set of questions monthly. See how to measure your AI visibility.

Notice that nothing on the list depends on which acronym you prefer.

A worked example (hypothetical)

Imagine a small landscaping company that receives two pitches in the same week. One offers "GEO optimization" and the other "LLMO packages". Both sound technical, and neither says what will actually be done.

The owner replies to each with the same four questions from above. One vendor comes back with a clear list: fix the robots.txt file that blocks all crawlers, make the service area consistent across the site and listings, add structured data, and set up a monthly question test. The other replies with a promise of top placement and a request for payment up front.

The labels were interchangeable. The answers were not. The owner can now choose on substance, which was the point. This scenario is invented to illustrate the approach and does not describe any real company.

Common mistakes with the terminology

• Assuming a new acronym means a new discipline. Most of the tasks are the same ones good websites already needed.
• Buying on the label. A vendor's choice of acronym says nothing about quality.
• Using jargon with customers. Most customers search for plain phrases, not for acronyms.
• Waiting for a standard. The parts that matter most, such as clear pages and accurate facts, work today.
• Skipping the basics for a shiny extra. Files like llms.txt can be a cheap addition, but they do not replace readable pages and consistent facts.

What to do this week

• Pick the label your audience recognizes, or skip labels and use plain phrases.
• Run through the checklist above and note the two weakest items.
• Fix one of them before the week is out.
• If you are evaluating a vendor, send them the four questions and compare answers.
