Recent reporting has highlighted evidence that ChatGPT is building and using its own search infrastructure, including a search index referred to as Labrador in antitrust testimony and job postings. For SEO teams, the important shift is simple: ChatGPT visibility may depend on more than how a page performs in Google.
What the Labrador reports mean
The reports describe an internal search index used to support ChatGPT search. The existence of a separate retrieval system does not mean Google SEO stops mattering. It means AI search can have its own discovery and retrieval path.
Why SEOs should care
A page can rank well in Google and still be difficult for an AI system to retrieve for a specific prompt. Conversely, a useful page may be surfaced in an AI answer even when it is not a top organic result.
What to measure
- Brand mentions in ChatGPT answers.
- Cited URLs from your site.
- Pages retrieved for important prompts.
- Referral traffic from AI products.
- Conversions from AI-referred users.
How to prepare content
Keep important pages crawlable, useful and easy to understand. Use descriptive headings, clear entity names, original information and direct answers. Avoid creating thin pages only because a new AI search system exists.
Build a prompt test set
- List commercial questions customers ask.
- Add comparison and problem-solving prompts.
- Record cited sources and brand mentions.
- Repeat the test monthly and after major AI search changes.
- Compare retrieval with organic performance.
Do not chase citations blindly
A citation is useful only when the underlying page satisfies the user. Improve the page first. Then use AI-search tracking to see whether the stronger page is retrieved and cited more often.
How this fits with Google SEO
Keep technical SEO, internal linking and strong content as the foundation. Add AI-search measurement on top. You do not need two completely separate content strategies for every search engine.
