You can work on your content endlessly, but if AI cannot reach, read, understand or trust your website, you will not appear in the answers. A GEO audit exposes those blind spots. It is not an SEO audit in a new coat: where classic audits look at ranking factors, a GEO audit checks whether generative AI can actually process and cite your site. For the fundamental difference between the two channels, see GEO vs SEO: the difference and why you need both. Where What is an AI readiness score? explains why the four pillars matter, this checklist gives you the concrete points to tick off: 20 control points, spread across those four pillars. Work through them, and you will know exactly where your website is AI-proof and where it is not.
Pillar 1: Technical accessibility
The first question is whether AI can reach and see your site at all. This is the pillar where most websites unintentionally lose points.
- Are you letting the search crawlers in? Check in your
robots.txtthat you are not blocking the search crawlers. OpenAI confirms that sites that block OAI-SearchBot do not appear in the search answers of ChatGPT. The same goes for PerplexityBot. - Block on purpose, not by accident. If you do not want to be used for training, block the training crawler (GPTBot) specifically, or use Google-Extended for Gemini training. That does not hurt your search visibility, while a blanket block does.
- Is your core content in the server HTML? Most AI crawlers do not run JavaScript. According to an analysis by Vercel, the crawlers of ChatGPT and Claude do fetch JavaScript but do not execute it. Test it: turn JavaScript off or view your page source, and check whether your text is still there.
- Does your site run on HTTPS and load fast? A valid certificate and a quick load time are basic conditions for every crawler. Slow or heavy pages are fetched less thoroughly.
- Are your important pages indexable? Check for unintended
noindextags or blocks, and make sure your sitemap is up to date and contains your key pages.
Pillar 2: Structured data
The second pillar makes your page machine-readable. An important nuance up front: structured data is a hygiene factor, not a citation miracle cure. Ahrefs studied 1,885 pages and found that schema on its own barely adds AI citations. So do it for clear machine readability and search engine context, not as a magic button.
- Do you have correct Schema.org JSON-LD? Give your key pages valid structured data: Organization, WebSite and the right type per page type (Article for a blog, Product for a webshop).
- Is there FAQPage schema on your FAQ pages? Only where the FAQ is also visible on the page, with the question and answer matching the schema one-to-one.
- Are you using BreadcrumbList? Breadcrumbs give AI and search engines navigation context about where a page fits in your site.
- One schema block, no conflicts. Use a single
@graphwith@idreferences between entities, no duplicate or conflicting schema blocks on the same page. - Does your schema match the visible content? Never invent data such as reviews or ratings that are not on the page. Schema that deviates from the visible text is a risk, not a gain.
Pillar 3: Content signals
The third pillar determines whether AI can understand your content and pull passages from it. The academic GEO research shows that content with a clear structure, concrete figures and sources gets cited the most.
- Start every section with the answer. Write according to BLUF logic: the first sentence under a heading gives the direct answer, only then the context. AI models cite that first sentence.
- Use a clear heading structure. One concept per H2, phrased as the question your audience asks, so your heading matches the prompt.
- Back it up with concrete figures and sources. Replace vague claims with verifiable figures and source attribution. That increases your citeability and your credibility.
- Make your content extractable. Use definitions, numbered lists and tables. Structured content is easier for a model to take over than long blocks of text.
- Choose depth over breadth. Deep, specific content about one niche scores better in AI answers than shallow content about everything. Build authority in a defined topic.
Pillar 4: Authority
The fourth pillar determines whether AI recognizes you as a trustworthy entity. This is largely off-site work and builds over the longer term. It is also the pillar where you see results slowest, but the most durable: a brand that AI consistently recognizes as an authority stays in view longer than a brand that is only technically in order.
- Are you a consistent entity? Use the same brand name and details everywhere, with a clear About page and Person or Organization schema, so AI knows who you are.
- Are you mentioned externally? Mentions in authoritative, independent sources such as press, trade publications and industry bodies strengthen your entity recognition. This is the GEO equivalent of link building.
- Do you have reviews on authoritative platforms? AI models often consult review platforms for recommendation questions, so consistent, genuine reviews carry weight.
- Are you findable as an entity? A presence in sources that AI models rely on heavily, such as Wikipedia where relevant, strengthens your recognition. Do not force anything, but seize the chance where it is legitimate.
- Do you optimize per language? If your audience is multilingual, optimize per language separately. A French-language question draws from French-language sources, so language-specific work is a core factor for any multilingual market.
How do you use this checklist?
Start at the top, because the pillars are ordered by impact. Perfect authority does not help if an AI crawler is not allowed onto your site or cannot read your content. So work through pillar 1 and 2 first, those are technical points you often fix within a day, and then keep building on content and authority. Many sites already gain quickly from pillar 1 alone, because one wrongly set rule in robots.txt can be the difference between appearing in ChatGPT or not.
A manual run-through gets you far, but the measurable parts, such as your actual appearance in AI answers and your score per pillar, call for a tool. Veesie runs this GEO audit automatically and measures your AI visibility and GEO Score across ChatGPT, Claude, Gemini and Perplexity for marketers and agencies, and sums it up in an AI readiness score from 0 to 100 with concrete action points per category.
What do you do with the outcome of your GEO audit?
An audit is only valuable when you act on it. Do not simply count your points, but prioritize on impact: a blocked crawler or unreadable content weighs far heavier than a missing breadcrumb. Tackle the blocks that make you completely invisible first, and then work toward the fine-tuning.
Next, compare your position with the GEO benchmark per sector. If you see that competitors in your sector score higher, you know where the catch-up work lies. Veesie measures your AI visibility and keeps the GEO Score of your brand across ChatGPT, Claude, Gemini and Perplexity side by side with your AI readiness for marketers and agencies, so you can see whether a technical fix translates into more mentions. A strong audit without follow-up is a snapshot, an audit you repeat becomes a steering instrument.

Conclusion: AI-proof first, citeable second
A GEO audit comes down to one principle: first make sure AI can reach, read, understand and trust your site, and only then worry about getting cited more often. Most brands skip step one and wonder why their good content never shows up. With this checklist you reverse that order: get the technical foundation right first, then take on the content battle for the citation.
Work through these 20 points, fix the blind spots and measure the result. Veesie measures your AI visibility and GEO Score across ChatGPT, Claude, Gemini and Perplexity for marketers and agencies, so you do a GEO audit not as a one-off exercise but as an ongoing process. Because a website that AI cannot process stays invisible, no matter how good your content is. Want to know what counts after that, read 8 tips to improve your GEO Score. New to the topic?
