Generative Engine Optimization: Get Cited by AI
Generative engine optimization (GEO) is the practice of making your pages easy for AI assistants and AI search features to read and cite in their answers. In practice it means letting AI crawlers in, answering questions directly, keeping facts sourced and structured, and being the clearest page on the topic.
It overlaps with SEO more than the new name suggests. Here’s what’s different, what you can control, and what nobody can promise.
What is generative engine optimization?
The term comes from a 2023 research paper that studied how to make content more visible in answers written by generative engines: ChatGPT with search, Perplexity, Google’s AI Overviews and similar tools. Instead of ten blue links, these tools write an answer and cite a few sources, or none.
Classic SEO asks how to rank on a results page. GEO asks how to become one of the sources an answer is built from. The audiences differ too. A results page is read by a person deciding where to click. An AI answer is assembled by a model that reads your page for you and decides which sentence to use.
Why do some pages get cited and others don’t?
Picture a hypothetical founder, Ana, who runs a small invoicing app and writes a solid guide on late payment reminders. It ranks on the first page of Google. But when she asks an assistant the same question, the answer cites a competitor’s shorter page, and hers isn’t mentioned.
She compares the two. Her guide opens with three paragraphs about cash flow before it gives an answer. The competitor’s page answers in the first two sentences, then has a table of reminder timings, then a short FAQ. Her page also blocks one AI crawler in robots.txt, a setting left over from a site template.
None of this proves why the assistant chose one page over the other. AI providers don’t publish how they pick sources, and answers change from one run to the next. But the differences Ana found are the ones you can fix, and each one also makes the page better for human readers.
What can you control for AI citations?
More than you might expect, though none of it guarantees a citation.
| Lever | What to do | Why it plausibly helps |
|---|---|---|
| Crawler access | Check robots.txt for the AI crawlers you want, such as GPTBot or ClaudeBot | A page a crawler can’t fetch can’t be read or quoted |
| Direct answer | Answer the query in the first two sentences | Gives the model a self-contained passage to quote |
| Question headings | Write H2s as the questions people ask | Matches the shape of the questions users type into assistants |
| Tables | Put comparisons in tables | Structured facts are easy to extract accurately |
| Sources | Link the source of every number | Makes the page safer to repeat |
| Freshness | Update dates and facts when things change | Assistants answering current questions favor current information |
| Clarity on who you are | An About page, a named author, consistent product facts | Helps a model attribute claims correctly |
Most of these are ordinary good SEO. Our guide on blog post structure for SEO covers the on-page template, and FAQ sections for SEO covers the questions at the end.
Is llms.txt worth adding?
llms.txt is a proposed file, placed at the root of a site, that gives language models a short Markdown guide to your most important pages. It’s a proposal, not a standard, and it isn’t clear how many AI providers read it today. Adding one is cheap, so there’s little harm in it. Just don’t expect it to do much on its own, and don’t let it replace the work on the pages themselves.
How is GEO different from SEO?
The two share most of their methods and differ mainly in who reads the page first.
| SEO | GEO | |
|---|---|---|
| Goal | Rank on a results page | Be quoted or cited in an AI answer |
| Who reads first | A person scanning results | A model reading the page for the person |
| What wins | Relevance, links, a good result snippet | Clear, quotable, sourced passages |
| Measurement | Rankings, clicks, impressions | Hard to measure; few reliable tools yet |
| Overlap | Large | Large |
The measurement row is the honest weak spot. You can check whether assistants cite you for a handful of questions by asking them, but answers vary between runs and users. Treat anyone who promises a guaranteed citation rate with caution.
Where does GEO not matter much?
If your buyers find you through referrals or direct sales, AI citations may barely move your business, and your time is better spent elsewhere. The same goes for pages that don’t answer questions, like a login page or a checkout. GEO matters most for content that answers the questions your buyers ask before they buy.
How can you check a page for AI-citation readiness?
Start by hand: read your robots.txt for AI crawler rules, read the first two sentences of your key pages, and ask two or three assistants the question each page targets. Note who gets cited.
Copix Complete includes a page action in its seo tool that audits a live URL. It runs on-page checks and an AI-citation readiness score for a query, and it checks the host’s robots rules and llms.txt for AI crawler access. Each run spends SEO credits and reports what it found with a note on what ran. It can’t tell you whether an assistant will cite you; nothing can. If you only have a few key pages, the manual check above is enough. If you manage many, see the SEO section, compare the plans, or read whether AI content is bad for SEO if your pages are drafted with AI. The copy tools are on the home page.
FAQ
Is GEO replacing SEO?
SEO still comes first. AI answers draw heavily on pages that search engines already index, so the basics of SEO still decide whether your page is found at all. GEO adds a layer on top: making the page easy to quote.
Should I block AI crawlers?
It depends on what you want from those tools. Blocking them keeps your content out of some training or answers, and it also removes the chance of being cited by those tools. Decide per crawler, and check that your robots.txt says what you mean.
How do I know if ChatGPT or Perplexity cites my site?
Ask them the questions your pages answer and look at the sources. Some tools also show up as referrers in your analytics. Results vary between runs, so check more than once before drawing conclusions.
Do AI answers prefer long or short pages?
There’s no published rule. Pages that answer clearly near the top and keep each section focused are easier to quote, whatever their length.
Does GEO work for small sites?
A small site can be the clearest answer to a narrow question. Being specific and accurate matters more than size for many niche queries, though nothing guarantees a citation.
