What is GEO content?
GEO content is content written and set up for generative engine optimization: raising the odds that an AI search engine picks your page as a source and names your brand in its answer. It is not a separate genre with secret tricks. It is plain good content, with a few requirements that weigh more heavily than they do in classic SEO.
Google says as much. Its documentation on AI features and your website states that there are no additional requirements or special optimizations needed to appear in AI Overviews or AI Mode, and that you do not need to create new AI text files or special markup. A page has to be indexed and eligible to be shown with a snippet; beyond that, the advice is to make helpful, reliable content written for people.
So what sets GEO content apart is not a hidden technique but emphasis: verifiable facts, clear sources, an answer that can be quoted on its own, and a company that is recognisable as an entity. Those are exactly the things that tend to disappear when you outsource content with nothing more than a topic and a deadline.
Why an ordinary content brief is not enough
An ordinary content brief is aimed at Google rankings, while AI search engines largely cite different sources. Brief for SEO alone and you get content that can rank in Google but stays invisible in AI answers.
Research across 1,000 queries, which we summarise in AI search vs Google: they cite different sources, found that the median overlap between GPT-4o's sources and the Google top 10 was 0%. For more than half of the queries, GPT-4o did not cite a single domain from the Google top 10. Ranking and being cited are two different games.
What AI search engines do reward was studied in GEO: Generative Engine Optimization, by researchers from Princeton and IIT Delhi, presented at KDD 2024. On a benchmark of 10,000 queries they compared nine ways of rewriting text. Adding quotations, adding statistics and citing sources came out on top; the best methods raised visibility in AI answers by up to around 40%. Keyword stuffing did little or nothing, and in a test on Perplexity it did 10% worse than the original.
For a content brief, that means word count and keyword density tell you very little. What counts is how much checkable evidence is in the text.
What goes in the brief: who supplies what
A brief for GEO content sets out, next to topic and audience, which evidence has to go into the text and who supplies it. The key point for clients: part of that evidence can only come from you.
| Part of the brief | Why it matters to AI search engines | Who supplies it |
|---|---|---|
| The question the page answers | AI systems look for a passage that answers a question directly | Both; the agency drafts, you check |
| Your own figures, project results, price ranges | Adding statistics was one of the strongest methods in the GEO research; nobody else has your data | You |
| Expertise and real examples | Concrete, first-hand information sets you apart from generic content | You (an interview or input from your specialists) |
| External sources for claims | Citing sources raises visibility; AI can check the claims | The agency |
| Quotes from experts or customers | Adding quotations scored highest in the GEO research | You supply the people, the agency writes them in |
| Author with role and profile | Makes the source recognisable and checkable | You (who stands behind it), the agency puts it on the page |
| Company details such as name, address and services | Consistent entity details help AI recognise your business | You supply them, the agency applies them consistently |
Skip the first four rows and you get a text that reads well but that any other company in your industry could have published. So when you outsource, plan a fixed moment each month when you or a colleague provides input. For the part of the work that sits outside the writing, see how we approach content and conversion.
Acceptance criteria: when an article is done
Agree on the criteria every delivered article has to meet, so you can check it rather than approve it on gut feeling. The same criteria make a good test for proposals.
- A direct answer in every section. Each subheading opens with a sentence that answers that section's question on its own.
- A source for every numerical claim. Every figure and every standard links to a source the agency has checked itself.
- At least one fact of your own. A figure, result or example from your business that appears nowhere else.
- Author and date, visible and machine-readable. Name and role on the page, publication and update dates in the code.
- Structured data that matches the text. Google asks that structured data matches the visible content; no schema for content that is not on the page.
- No filler. A paragraph you can delete without losing any information comes out.
Why spell it out? In our research across 310 Dutch SME websites, only 3 of 354 pages containing figures or claims linked to an independent source, and 41% of the sites had no machine-readable date. Without clear agreements, this is usually where it goes wrong.
What your content partner has to sort out beyond the text
GEO content only works when the site around it is readable and recognisable for AI systems; a good text on a site that blocks AI crawlers will not be found. So agree on who checks these points, even if you only outsource the content.
- Access for AI crawlers. In our research, GPTBot had no or insufficient access to 20% of the sites, while only one site had set that up deliberately in robots.txt. It is usually down to firewall or hosting settings.
- Organisation details as structured data. 52% of the sites we studied had no Organization or LocalBusiness schema, and 89% had no machine-readable address.
- Consistent mentions beyond your site. The same company name, description and details on your site, in business profiles and in mentions elsewhere.
- Indexing and snippets. Google names indexing and snippet eligibility as the only technical requirements; a noindex or nosnippet in the wrong place shuts a page out.
Measuring whether GEO content works
You measure GEO content separately from your Google rankings: with a fixed set of questions that you put to several AI search engines repeatedly, tracking whether your brand and your pages are mentioned. A rise in Google says little about AI visibility, because the sources largely differ.
Agree with your content partner on:
- A baseline before you start. Which questions does AI answer today, and are you in the answer?
- Several runs per question. AI answers vary; one screenshot is not a measurement.
- Several engines. ChatGPT, Perplexity, Gemini and Google AI Overviews behave differently.
- A separate report next to your SEO figures, so you can follow both on their own.

Red flags in a GEO content proposal
A GEO content proposal deserves suspicion when it promises mostly words, keywords and guarantees, and says little about evidence, sources and measurement. Watch for these signs:
| Sign in the proposal | Why it is a risk |
|---|---|
| A guaranteed mention in ChatGPT or AI Overviews | Google itself says inclusion is not guaranteed; nobody can promise this |
| Price per word only, with no source research | Rewards length, while evidence is what makes the difference |
| Keyword density as a quality measure | Keyword stuffing did worse than doing nothing in the GEO research |
| No request for your figures or experts | Then you get generic content with no evidence of your own |
| Reporting on Google positions only | Says nothing about AI visibility |
| Fully AI-generated text with no review | Google's guidance on generative AI content advises fact-checking all AI content by hand; mass-generated pages that add no value can fall under its spam policies |
Frequently asked questions about outsourcing GEO content
What is the difference between SEO content and GEO content?
SEO content aims for a high position in Google, GEO content aims to be cited in AI answers. In practice they overlap a great deal, but GEO content puts more weight on sources, figures, quotes, a direct answer in every section and recognisable entity details.
Do you need special markup or an llms.txt for AI Overviews?
No, not according to Google. AI Overviews and AI Mode need no additional technical requirements, AI files or special schema. A page has to be indexed and eligible to be shown with a snippet.
What do I need to supply myself when I outsource GEO content?
You supply what only your business has: your own figures and results, real examples, the expertise of your specialists, quotes, and an author with a name and a role. The agency takes care of structure, external sources and the technical side.
Can an agency guarantee that ChatGPT will mention my business?
No. No agency controls what an AI model answers, and Google says inclusion in its AI features is not guaranteed. An agency can raise the odds and measure whether it is working.
How long does it take before GEO content shows results?
It differs per engine and per topic, because AI systems first have to find and process the pages. So agree on a baseline and fixed measurement moments, so you see a trend instead of guessing.
Does it work to turn existing content into GEO content?
Yes, and it is often the quickest win. Pages that already do well in Google but do not show up in AI answers get a direct answer in every section, sources for their claims, figures of your own and structured data that matches the text.
