We optimize pages for AI models and test the result before you publish

We build a test environment that selects pages the same way AI search engines do. It shows whether your content will help your brand in AI answers before you publish, not after.We keep only the edits that worked, so that ChatGPT, Claude and Gemini cite your pages more often and mention your brand more prominently, and we confirm the result on real AI models.

GEO optimization is
not a one-time job.

AI models update often, and competitors publish new pages and improve old ones. To keep your brand from losing ground in AI answers, we repeat the cycle again and again.

Measurement

How much audience attention your brand captures in AI answers.

At Citeus, we build hundreds of prompts for your category that resemble how people actually ask AI models, and send them to ChatGPT, Claude, Gemini and, if needed, other AI models.

For your brand and each competitor, we calculate an attention index. The attention index shows how noticeable and memorable a brand is in AI answers and takes into account not only the brand’s visibility and position in each answer, but also how much detail the answer gives, how well the mention matches the user’s intent, and other factors.

We also estimate which sources and domains drive this brand attention the most.

Test environment

Built from the pages yours actually compete with in AI answers.

Our test environment reproduces AI search on a corpus of real pages. The corpus includes pages that AI models cited in the measurement step and pages that the search engine returned for fan-out queries but that did not make it into the answer. Fan-out queries are the sub-queries an AI model splits a user’s question into before it searches the web.

We add your website’s pages to the corpus, existing or new. On this corpus, the environment follows the same path as an AI model: it searches for pages, selects the best ones and writes an answer with links to them.

The test environment shows a page’s GEO potential in minutes, not weeks. In the test environment, the effect of an edit doesn’t get mixed up with competitors’ actions or search index updates.

With every cycle, we refine the test environment: we add pages from the latest measurement and compare the environment’s answers with the answers of real AI models.

Optimization

We edit your pages so they rank higher in the test environment.

We edit your pages: markup, structure and copy. Every edit runs through the same prompts as in the measurement step, so we see which changes get the page into AI answers and which don’t.

The edits we try draw on optimization methods studied and tested in academic GEO research and in our own experiments.

You get ready-to-use pages: the versions that AI models cite most often in the test environment.

We can preserve your SEO markup, brand tone of voice and other page requirements, so the pages stay useful for people and classic search, not just for AI models.

Once the optimized pages are live, the next measurement in ChatGPT, Claude and Gemini shows how brand mentions and citations have changed. Then the cycle can be run again with the next page.

A US travel project came to us before a full rebrand: a new domain, a new name and a rebuilt website with all-new copy. The niche and positioning were already settled. The goal was to make the pages of the future site more visible to AI models.

We optimized the draft of the new site and brought the new site into the top 5 by prominence in AI answers.

Measurement

We built a set of several dozen prompts that mirrors how real people ask AI models about travel and covers the whole category. As usual, we ran it in ChatGPT, Claude and Gemini, more than ten times each, enough runs to make the results statistically reliable. In the first measurement, the client’s brand was absent from AI answers.

Test environment

We collected 5,200+ real pages: the ones LLMs cited in our measurements and the ones the search index ranked highest for the 700+ queries LLMs made while answering. On this corpus, we reproduced AI search with three parts: a search algorithm, an LLM reranker and an LLM generator. Together they reproduce RAG (retrieval-augmented generation), the way AI models find sources and write answers based on them.

Optimization

We edited the draft pages step by step and checked every edit in the test environment on the same prompts. Only the edits that worked made it into the final version. As a result, the draft of the new site went from absence to the top 5 by prominence.

Realistic prompt set

Real conversations, no brand names.

Prompts should reflect how people actually talk to AI models: conversations and long, detailed questions, not short Google-style queries.

A perfectly realistic prompt set doesn’t exist, because what people ask ChatGPT, Claude and Gemini stays private. The one exception is Google AI Overviews, which answers regular Google queries. So any prompt set is a benchmark: an approximation of reality, not reality itself.

We build your prompt set from datasets of real conversations between people and AI models and from modern intent taxonomies, which classify what users want from an AI model.

Our prompts contain no brand names. A prompt that names a brand gives it close to 100% visibility and says nothing about the market. We want to know when the AI model names a brand on its own.

Beyond visibility

An integral index of brand attention in AI answers.

Brands don’t care about mentions for their own sake. They care about what mentions produce: visits, consideration and, eventually, purchases. In AI systems, these outcomes can’t be measured directly yet.

Most GEO tools rely on proxies such as visibility, average position or sentiment. Each of them captures only one aspect of a mention.

At Citeus, we believe the closest measurable proxy for purchase intent is the attention people pay to brands in AI answers. Brand attention depends on whether the brand appears, where the brand stands, how well the mention matches the user’s request and how much detail the brand gets. We combine these signals into a single attention index, measured across many responses from multiple LLMs.

We also calculate source weights: which pages and domains drive this attention for your brand, for each competitor and for the category as a whole. This shows where to focus first.

Tested edits, not urban legends

A test environment built on your category.

We test every GEO edit on pages from your own category instead of relying on generic recipes. GEO advice often rests on such recipes, and, as everywhere else, universal advice can work very differently in your industry. Our test environment is built from pages in your category: the pages yours actually compete with in AI answers.

The test environment rules out outside factors such as search index updates and new competitor publications, so you can focus on the effect of the edit itself. It helps optimize existing pages and create new ones and shows a page’s GEO potential before the page goes live.

Grounded in science

GEO methodology based on research.

Our GEO methodology is based on the best available research, and we keep updating it as new papers come out. GEO interests not only marketers but also researchers. We read scientific papers ourselves, with our own eyes, the way it was done before AI: this way we don’t miss details or make mistakes in our conclusions.

We are not looking for what “works”: put that way, it’s a conversation for marketers. We want to understand what “works” means, how we know something works, whether there is evidence that this particular thing works and not something else, and why it works. We bring academic knowledge into practice and adapt it to the applied task of GEO.
