The technical gates that determine whether a source can enter an AI search system’s searchable universe.
Crawling creates the possibility of discovery
Before a public webpage can participate in retrieval, an authorized crawler generally needs to access it. Robots controls, authentication, network errors, rendering failures, and inaccessible navigation can all remove a source before content quality is considered.
OpenAI distinguishes OAI-SearchBot, which supports discovery in ChatGPT search experiences, from GPTBot, which relates to potential model training. Allowing search discovery and allowing training are separate publisher decisions.
Indexing is a necessary state, not a visibility outcome
An accessible page may still be excluded from an index, treated as a duplicate, or deemed ineligible for a particular result. Indexing makes retrieval possible; it does not guarantee that retrieval will happen.
Google states that pages shown as supporting links in its AI features must meet ordinary Search technical requirements and be eligible to appear with a snippet. It does not require special AI markup.
Keep the technical states separate
A useful audit distinguishes at least four states: crawlable but not indexed; indexed but not retrieved; retrieved but not cited; and cited or used in the answer. Collapsing these states into “the AI cannot see us” prevents precise diagnosis.
Eligibility creates opportunity, not exposure.
Every downstream outcome remains conditional on retrieval, context selection, and generation.
Questions about this topic
Is OAI-SearchBot the same as GPTBot?+
No. OpenAI describes OAI-SearchBot as supporting search discovery, while GPTBot controls potential use for model training.
Does being indexed guarantee an AI citation?+
No. Indexing only makes a page eligible to be considered. The page must still be retrieved, selected for context, used, and visibly cited.
Do I need special GEO schema for Google AI features?+
Google says no special AI schema or markup is required. Standard crawlability, indexing eligibility, helpful content, and Search technical requirements remain foundational.
