Generative Engine Optimization: how to tell whether an AI can cite your website
Generative Engine Optimization (GEO) is the practice of making a website readable, understandable and quotable by generative models, so that it becomes one of the sources cited inside an AI answer. It overlaps with SEO in its technical foundations but rewards different signals: SEO optimizes for a position in a list of links, GEO optimizes for being the source named in the answer itself.
The question your site was optimized for is disappearing
For twenty years the goal was to appear in a list of 10 blue links. Increasingly the user gets one written answer with 3 or 4 sources attached. Either you are one of those sources or you are absent — there is no second page to land on.
The problem is that the signals that made you rank are not the signals that make you citable. A model does not weigh your backlink profile. It weighs whether your content can be extracted in self-contained fragments, attributed to an identifiable entity, and verified against something outside your own claims. Very few sites are built that way yet, which is why the gap between you and your competitors is narrower right now than it will ever be again.
What decides whether an AI cites you?
| Layer | Weight | What it asks |
|---|---|---|
| Discoverability | 25 | Can AI crawlers reach you, and do they know what they may do with your content? robots.txt, per-agent rules, sitemap, llms.txt. |
| Content accessibility | 30 | Does what a bot sees resemble what a person sees? This is where the rendering ratio lives. |
| Semantic structure | 30 | Can your content be sliced and quoted without losing meaning? Structured data, heading hierarchy, direct answers. |
| Entity authority | 15 | Can models identify you as a specific, consistent entity rather than one more website? |
Content accessibility and semantic structure weigh 30 % each, discoverability 25 % and entity authority 15 %. The one that fails most often is the rendering ratio: how much of your content only exists after JavaScript executes. A crawler that does not run your JS sees an empty shell where your argument should be. You can be first on Google and invisible to a model at the same time, and nothing in your analytics will tell you.
There is a fifth layer — whether your brand actually shows up in each model's answers. It cannot be measured by scanning a page: it takes hundreds of queries per engine, adapted to your category.
Does GEO replace SEO?
| SEO | GEO | |
|---|---|---|
| Goal | A position in a list | Being the cited source |
| Rewards | Links, domain authority | Extractable, attributable, verifiable content |
| Unit | The page | The quotable fragment |
Nothing GEO asks for damages your search ranking, and several of its requirements improve it: extractable content overlaps heavily with the quality criteria search engines already reward.
How do I know if AI can cite my site?
We built Primafonte to score this without guesswork: paste a URL and it returns a Citability Index from 0 to 100 with the four layers broken down and the concrete fix for each finding. The full report is shown in full — no sign-up, no email.
We built it because we needed it ourselves. This site is audited with it.
The diagnosis is the easy part
Plenty of tools will tell you that AI does not mention you and hand you a task list. The list becomes a backlog nobody prioritizes, because fixing it properly means touching the architecture of the site, not adding a tag.
So we also do the other half: a product landing built GEO-aligned from the start, or a rebuild of an existing WordPress site — same design, same content, same Google positioning, on a foundation models can actually read. Audit before and after, so the change is measurable rather than asserted.
