What is GEO, and how is it different from SEO?

Generative Engine Optimization (GEO) is the practice of structuring a website so that AI assistants like ChatGPT, Perplexity, Gemini and Google's AI Overviews can find it, understand what the business is, and cite it in their answers. SEO is the practice of ranking a page in a list of search results. They overlap, but they select for different things, and a site can do well at one while being invisible to the other.

This post explains the difference, what GEO actually involves, and what to do first if you run a small business.

What is Generative Engine Optimization?

GEO is optimisation for answers rather than for rankings. When someone asks an AI assistant "who is a good web developer in Colombo" or "what does a five-day website build include", the assistant does not return ten links. It reads a handful of sources, decides which ones it trusts, and writes one answer that names some of them. GEO is the work of being one of the sources it reads and one of the names it uses.

The term appeared in 2023 as AI assistants started answering commercial questions directly. The techniques are older: clear entity information, structured data, direct answers and consistent facts have been good practice for years. What changed is that they went from helpful to decisive.

How is GEO different from SEO?

SEO earns a position in a list; GEO earns a mention in a generated answer. That difference changes what each one rewards.

Three practical differences follow from that table.

First, assistants quote sentences, not pages. A page that ranks well because it is long and thorough may never be quoted because its facts are spread across 2,000 words of marketing prose. A short page with a plain definition in its first sentence gets lifted.

Second, assistants cross-check. If your about page says you were founded in 2026, your schema says 2024 and your LinkedIn says something else, an assistant treats the fact as unreliable and leaves you out. Consistency across surfaces is a GEO requirement and only a minor SEO concern.

Third, assistants read structure directly. Structured data, headings phrased as questions, lists and tables are not decoration. They are how the assistant works out what the page is claiming.

Does GEO replace SEO?

No. GEO builds on SEO and does not work without it. An assistant cannot cite a page that is not indexed, loads slowly, or is blocked by a robots file. The technical half of SEO, meaning crawlability, speed, canonical URLs, sitemaps and Search Console, is the foundation GEO stands on.

The right order for a small business is:

1. Basic SEO: make the site indexable, fast and correctly labelled
2. GEO: make the facts on it clear, consistent and citable
3. Content over time: publish the comparisons and answers assistants look for

Skipping step one and doing step two is wasted work. Doing step one and stopping is what most business websites do today, which is why so few of them appear in AI answers.

What does GEO involve in practice?

Five pieces of work, in this order.

1. Define the entity

One sentence that states what the business is, what it does, and where. For example: "CcinoCode is a web development studio that designs, builds and launches business websites in 2 to 5 days, with search and AI-search optimisation included." That sentence then appears verbatim on the about page, in the Organization schema, in the homepage meta description and in llms.txt. Every crawler reads the same fact in the same words.

2. Add structured data

JSON-LD schema that confirms in machine-readable form what the text says: Organization on every page, Service on each service page, FAQPage wherever there are questions and answers, BreadcrumbList on nested pages, Article on posts like this one. Validated, not guessed.

3. Restructure content into questions and answers

Headings phrased the way people ask, with the direct answer in the first sentence beneath. "How long does a website take?" followed by "A landing page takes 2 to 3 days and a multi-page site takes 4 to 5 days" is quotable. "Our streamlined process" followed by three paragraphs is not.

4. Add llms.txt

A plain-text file at the root of the site that summarises the business, lists its services and links to the key pages. It is a proposed standard that a growing number of AI crawlers read first, and it costs nothing to provide.

5. Format for citation

Short paragraphs. Lists and tables for anything comparable. Visible published and updated dates. Specific claims with numbers, names and dates instead of adjectives. "Fast" cannot be quoted. "Live in five days" can.

How do you know if GEO is working?

By asking the assistants. Rank trackers do not cover generated answers, so the measurement is direct: ask ChatGPT, Perplexity and Gemini the questions your customers would ask, and read what they say. Do it before the work and again a few weeks after, since assistants re-crawl on their own schedules.

We do this as a free AI visibility check. You send your business name and website, and within two working days you get what each assistant says, what it gets wrong, and what to fix.

What should a small business do first?

Fix the about page. It is the page assistants read to work out what you are, and on most business sites it is the vaguest page on the domain. Rewrite its first sentence as a plain statement of what the business is, does and where. Then make sure the same sentence appears in your Organization schema. That single change is the highest-return hour of GEO work available, and it costs nothing.

After that, the order above: basic SEO if it has never been done, structured data, question-shaped content, llms.txt, and formatting. On a new build we do all five inside the timeline. On an existing site it depends on how much of the content needs restructuring.
