If a page is indexed but not retrieved by AI search engines, indexing only confirms crawl storage. Retrieval is a separate judgment about whether a fragment is extractable and worth grounding for a specific query.
To diagnose a page not retrieved by AI search engines: confirm the URL is indexed, then test whether a generative system cites or quotes a fragment from that URL for a target query. Indexing is crawl storage. Retrieval is eligibility. If indexed and still absent from answers, the usual causes are buried fragments, entity ambiguity, missing evidence, render-only text, or intent mismatch.

Diagnose why AI systems retrieve or surface your domain but fail to cite your content — covering citation eligibility, source confidence, and entity ambiguity.
Diagnose issue →Diagnose why your site is not appearing in AI-generated answers, AI Overviews, or LLM citations.
Diagnose issue →Understand why organic traffic declines while traditional rankings remain unchanged.
Diagnose issue →Identify why content is indexed but not cited in Google AI Overviews or other generative results.

Diagnose issue →Troubleshoot why structured data that previously worked is now ignored by generative engines.
Diagnose issue →People do not Google "best practices" when things break. They Google symptoms. These diagnostic guides map symptoms to failure modes and solutions.
Each diagnostic symptom maps to underlying decision traces in generative search. For intelligence framing on retrieval gaps, see LLM Compute Leak. For agent-ready remediation paths, see AI Agent Optimization.
Each diagnostic guide follows a symptom-first approach.
These guides funnel directly into GEO Failure Modes for detailed mechanics.
