What Is Generative Engine Optimization (GEO)? GEO vs SEO Explained for Business Owners

Over the past year, marketing conversations have picked up a whole set of new acronyms: GEO, AEO, LLMO, AI SEO. Agencies pitch "generative engine optimization", industry blogs write about "optimizing for AI", and business owners are left trying to figure out the basics. Is this a new discipline, a replacement for SEO or just a trendy name for the same old work? And do you need to pay for it separately?

Let's cut through the jargon. We will explain what an AI answer is and where your customers see it, what each acronym means, how GEO differs from SEO in results and metrics, and why one does not work without the other.

Where it all started: AI answers

All these acronyms exist because search itself has changed. People used to type a query and get a list of websites. Now they increasingly get an AI answer: a coherent text that an AI assistant wrote based on the pages it found. That text contains advice, numbers, company names and links to the websites it used as sources.

Customers see these answers in several places:

• In Google: AI Overviews on top of the search results, and AI Mode, where the whole search becomes a conversation.
• In AI assistants: ChatGPT, Gemini, Claude, Perplexity and Microsoft Copilot. People type "help me choose", "recommend" or "which is better" and get a list with explanations.
• In regional assistants: Yandex Alice AI in Russia, DeepSeek and Qwen in parts of Asia, and others depending on the market.

For users, it is convenient: no need to open ten tabs. For businesses, it is a new storefront, and a good ranking in regular search no longer guarantees a spot in it. We cover the platforms and answer formats in detail in our guide to AI search optimization.

What is generative engine optimization (GEO)?

GEO stands for generative engine optimization. "Generative engines" are AI systems that do not just return links but generate, that is, write, an answer. In marketing, GEO has nothing to do with geolocation or geotargeting, although the two get mixed up all the time.

GEO is the work of making sure AI assistants know your company, get the facts about it right, recommend it in their answers and cite its website. The work runs in two directions. On your website: technical accessibility, clear content and answers to customer questions. Beyond your website: brand mentions and articles on third-party sites that show your company can be trusted.

GEO vs AEO vs LLMO vs AI SEO: what the names mean

The short version: these are closely related names for the same field. The difference is what the person using the term wants to emphasize.

When a proposal lists "SEO, AEO and GEO", do not assume these are three separate services. Ask the agency a simple question: what specific work will be done, and how will you measure the results? To keep things clear, we use one term: GEO.

GEO vs SEO: what is the difference?

The main difference is where the customer sees the result and what exactly is being optimized. Here are the key differences in one table.

What gets optimized

SEO optimizes a page: it needs to rank higher than others for a specific query. GEO optimizes the company. An AI assistant does not answer with a link; it answers with a recommendation: "take a look at this company, it offers this and that." So what matters is not only the text on a page, but how consistently and clearly your company is described across the web. The same name, address and specialization on your website, in map listings and in directories. Experts with names and published work. Reviews on well-known platforms.

Where the result appears

The result of SEO is a position in a list, and the user decides what to click. The result of GEO is a presence inside the text the person reads first. That text often sits above the list of websites, and in AI chats there is no list at all. Your search ranking still matters, but the buyer sees it only after the AI has already named a couple of companies.

How results are measured

SEO metrics are familiar: rankings, impressions and clicks in Google Search Console and Bing Webmaster Tools, plus traffic in analytics. GEO adds a new metric: mentions in AI answers. We regularly run your tracked prompts through AI assistants and record three things: whether your company is named, which competitors appear next to it, and whether your website is cited as a source. The second metric is referral traffic from AI assistants, which you can segment in Google Analytics 4, as explained in our guide to tracking AI traffic in Google Analytics. Keep in mind that many users get their answer and never click, so clicks alone do not tell the whole story.

What SEO and GEO have in common

The differences are real, but both disciplines stand on the same foundation. In most cases, AI assistants find sources in a search index. Google AI Overviews and AI Mode are built on the Google index, and Copilot relies on Bing. When selecting sources, AI values the same things search engines have valued for years:

• the website is accessible to crawlers, loads fast and works without errors;
• pages are useful and answer the question directly;
• facts are specific and verifiable: prices, timelines, terms, company details;
• the company has authority beyond its own website.

That is why we call GEO a layer built on top of good old SEO. The way AI selects sources is already predictable enough, and consistent work on it delivers results, just as it does in SEO. We explain how AI decides whom to name in how AI assistants choose which businesses to recommend.

Why one does not work without the other

SEO without GEO: good rankings, fewer customers

A hypothetical example. A home remodeling company has ranked near the top for "kitchen remodeling in New York City" for years. Its rankings have not changed, but inquiries keep declining. Customers now ask AI assistants things like "how do I choose a kitchen remodeling contractor and what should I check in the contract?" The answer is assembled from a competitor's articles that spell out prices, project stages and warranties. Our company's website is indexed, but it has no direct answers to questions like these and almost no third-party mentions. So the AI names other companies.

GEO without SEO: plenty of articles, never cited

The opposite situation, also hypothetical. A company orders a batch of "articles for AI" and publishes them on its website. But the site is slow, some pages are not indexed because of technical errors, and the hosting firewall blocks unfamiliar crawlers. AI assistants either never find the articles or do not consider the website trustworthy. The money is spent, and AI answers stay the same.

The takeaway is simple: SEO gives your website a chance to be found, and GEO turns a website that gets found into a recommendation. You need both, ideally handled by one team. We explain why loud claims that "SEO is dead" do not hold up in practice in is SEO dead?

How to tell your business already needs GEO

The more expensive a wrong choice is for the customer, the more likely they are to ask for advice, including from AI. So it makes sense to start with GEO now if at least two of these points sound familiar:

• you sell services, B2B solutions or high-ticket products that people research and compare for a long time;
• customers ask a lot of questions before buying: about price, timelines, warranties and how you compare to competitors;
• your search rankings are stable, but clicks and inquiries are slowly declining;
• you asked an AI assistant to "recommend a company" in your industry and did not find yourself in the answer;
• AI assistants share outdated or wrong information about you;
• you sell in several countries or languages, and your buyers rely on Google, ChatGPT and Perplexity.

If none of these apply, that is no reason to relax. It is a reason to run a first AI visibility check and see where you are starting from, while few competitors in your industry are working on AI search on purpose.

What the work looks like when SEO and GEO run together

At AI Search Optimization, we do not split a website into a "search part" and an "AI part". The work runs as one stream:

• AI visibility audit. We check indexing and the technical health of your website and record what AI assistants currently say about you and your competitors.
• Prompt research. We add the questions customers ask AI to your keyword research.
• Technical fixes. We fix errors, speed up the site, give search engine and AI crawlers access, and add llms.txt and schema markup.
• New content. We write pages and articles that rank in search and are easy for AI assistants to summarize and cite.
• Brand mentions. We grow your company's presence on third-party websites.
• External publications. We create and publish articles in external sources to build the authority of your company and its experts.
• Tracking. We regularly check both search rankings and AI answers and adjust the plan.

One more important principle: AI evaluates your website as a whole. That is why we take care of the entire website from day one, from technical fixes to GEO. Audit recommendations do not wait months for a developer to become available. They are implemented by the same team that is responsible for them.

What this means for your marketing budget

When SEO and GEO are handled by different agencies, you pay twice for the same things: two audits, two sets of technical recommendations and two reports that someone still has to reconcile. When both are handled by one team, nothing is duplicated.

Our pricing is designed for ongoing work. The monthly fee is $290 per month, including the first 10 hours of specialist work. Every additional hour is $45. GEO work is billed on a time and materials basis: we invoice only the work completed and delivered that month. For example, 15 hours come to $515 and 20 hours to $740. A month heavy on content and publications takes more hours, and a quieter month takes fewer. We do not offer discounts or free months: the price is transparent from the first invoice.

The bottom line: not SEO or GEO, but SEO and GEO

GEO, AEO, LLMO and AI SEO all describe one goal: making sure AI knows your company and recommends it to customers. You get there not by abandoning SEO but by building on it. Search engine optimization makes your website visible and trustworthy, and GEO adds content for the questions people ask AI, third-party validation and a new way to measure results.
