Generative Engine Optimization: How to Get Cited by AI Answer Engines

Search is splitting in two. Traditional search returns a list of links and you pick one. An answer engine — ChatGPT, Claude, Perplexity, Google's AI Overviews — reads a set of sources and writes you a single answer, citing a handful of them. Generative Engine Optimization, or GEO, is the work of being one of those cited sources.

What is Generative Engine Optimization?

GEO is the practice of structuring a website so AI answer engines can read, extract and attribute its content. It overlaps heavily with technical SEO, but the unit of success is different. SEO optimises for a ranking position. GEO optimises for a quotation: a passage lifted out of your page and reproduced inside someone else's answer, with your name attached.

That difference changes what matters. A page can rank well and never be quoted, because nothing on it is extractable as a self-contained claim.

Why most websites are invisible to AI crawlers

This is the part that surprises people, so it is worth being concrete. Many modern websites are built as single-page applications in React, Vue or Angular. The server sends an almost empty HTML file, and JavaScript builds the page in the browser afterwards.

Googlebot executes JavaScript, so it copes. The AI crawlers largely do not. GPTBot, ClaudeBot, PerplexityBot and CCBot fetch the raw HTML and read what is there. On a client-rendered site, what is there is nothing.

We measured this on our own site before fixing it. Every URL on digova.ca served zero words of body content to a crawler that does not run JavaScript. Every page. After adding a prerender step to the build, the same URLs served between 350 and 730 words of real HTML. The content had always existed; it simply was not visible to anything that could not run a browser.

If your site is built this way, no amount of keyword work or schema markup will help, because there is nothing on the page to read.

How do I check whether my site has this problem?

You do not need tooling. Open your site, right-click and choose View Page Source — not Inspect, which shows the page after JavaScript has run. If the source is a short file with an empty <div id="root"></div> and no visible text, that is what a non-JavaScript crawler sees.

The fix is server-side rendering or prerendering at build time. Both produce real HTML for every URL.

What makes a passage worth citing?

Once your content is readable, the question becomes whether it is quotable. In practice, four things separate cited passages from ignored ones.

• A specific, checkable claim. "Prerendering took our pages from 0 to 552 indexable words" can be quoted. "We deliver excellent results" cannot, because there is nothing in it to lift.
• Original data. If a number exists only on your site, an engine that needs that number has to cite you. Benchmarks, survey results and measurements from your own projects are the highest-leverage content you can publish.
• Self-contained structure. A question as a heading, answered directly beneath it. Engines extract passages, so each section must make sense without the paragraphs around it.
• Attribution inside the text. Name your organisation in the sentence, not only in the page header, so your name travels with the quote.

Does structured data help?

Yes, but as a supporting act rather than the main one. Schema.org markup — Organization, Service, Article, Review, FAQPage — tells a machine what an entity is and how facts relate to each other. It resolves ambiguity, and it makes your content easier to attribute correctly.

What it will not do is compensate for a page with no readable text or no substantive claims. Structured data describes content; it does not replace it.

Should I allow AI crawlers?

That depends on your business, and it is a genuine decision rather than a technicality. Blocking GPTBot and ClaudeBot in robots.txt keeps your content out of AI training and retrieval — and out of the answers those tools generate.

For a business that wants to be recommended when someone asks an AI assistant for a supplier, blocking is usually the wrong trade. For a publisher whose archive is the product, it may be exactly right. Decide deliberately rather than by default.

Where to start

In order of impact: make sure your pages serve real HTML; publish something factual that nobody else can source; structure each section so it can be lifted and still make sense; then add the schema markup that ties it to your organisation.

The first step is the one most sites fail, and it is invisible until you go looking for it.
