Appearing in ChatGPT search

Spencer Thursfield · Published 2026-08 · Evidence: OpenAI documentation

ChatGPT search is the AI surface with the clearest published rules, because OpenAI documents the mechanics. Here is what the operator states. It is less than the advice industry implies, and more useful.

The three published requirements

1. Access. OAI-SearchBot must be able to fetch your pages. Check your robots.txt, and check the layers in front of it: CDNs and firewalls that block "bots" wholesale exclude you in silence. Required
2. Relevance. ChatGPT rewrites the user's question into search queries. Your pages compete on those rewritten queries, so clear subject matter in retrievable text counts for more than clever phrasing. Official recommendation
3. Reliability and usefulness. OpenAI says ranking considers both, and states that inclusion cannot be guaranteed. Anyone selling guaranteed ChatGPT placement is selling what the operator says does not exist. Official recommendation

The measurable part

ChatGPT referral clicks arrive labelled: OpenAI appends utm_source=chatgpt.com to applicable links. Your analytics can count them today; see tracking ChatGPT referrals. This makes ChatGPT the easiest AI surface to connect visibility to actual visits.

What remains unknown

How often ChatGPT search cites small-business sites directly rather than directories and editorial sources; how stable its citations are between runs; whether its selections resemble Google's. Our benchmark measures these gaps. ChatGPT search is one of the pilot's three systems.
