Your Site Is on Google — but ChatGPT Has No Idea It Exists

Google looks at backlinks, behavioral signals, and keywords when ranking. AI search engines — ChatGPT with web access, Perplexity, Google AI Overviews — look for something different when generating answers: machine-readable signals that a source is trustworthy.

If a site has no structured markup, the neural network sees plain text. It can't tell who the author is, what the organization does, or whether the content is credible. Without that context, the site doesn't make it into the answer — even if it ranks #1 in organic search.

Specifically, AI looks for:

JSON-LD markup (Schema.org) — the primary language a site uses to communicate with AI. Organization, Article, FAQPage, HowTo. Without JSON-LD, the neural network is flying blind.

E-E-A-T signals — authorship, publication date, an About page, contact information. ChatGPT and Perplexity evaluate trust in source selection much the same way Google does — only stricter.

FAQPage and HowTo schemas — the formats AI cites most often. The question-and-answer structure fits perfectly into a generative response: the model simply pulls a ready-made fragment.

OpenGraph tags — og:title and og:description are used by AI to understand page content, not just social networks.

Canonical URL and lang attribute — signals that the page is the primary source and is written in a specific language.

ChatGPT's audience is around 800 million users per week according to Reuters data from early 2025. This isn't the future. It's already happening with your customers today.

An e-commerce store can rank first for a query in search — and still be absent from the AI answer, because a competitor has FAQPage markup and they don't. A marketer managing 10 client sites may not know that half of them are invisible to Gemini and Perplexity — simply because no one checked.

Manually checking every signal means opening the page source, hunting for JSON-LD, inspecting meta tags, verifying canonical. An hour's work per site, if you know what you're looking for.

The report shows:

If the audit found problems, here's the priority order:

Step 1. Organization schema. The baseline trust signal for all AI systems. Name, URL, description, contacts, social media links — all in JSON-LD format. Without this, everything else works at half strength.

Step 2. FAQPage on key pages. Create a block with real customer questions and mark it up. This is exactly the content ChatGPT, Perplexity, and AI search pull into answers most often.

Step 3. E-E-A-T. An About page with specifics, contact information, article authors with publication dates. Sounds obvious — but most sites haven't done it.

Step 4. Canonical and lang. The technical minimum that's often skipped at launch and forgotten afterward.
