Run the citation-ready passage test
Check whether a passage states a bounded answer, names its evidence, exposes important limits, and remains understandable outside the surrounding page.
Citations
Make the answer easy to evaluate
Separate eligibility from citation-worthiness, expose sources, clarify entities, and write passages that survive retrieval out of context.
Evidence
Classify claims before drafting
Distinguish facts, observations, interpretations, recommendations, and opinions so each receives appropriate support.
Workflow
Use AI without publishing generic work
Bound the brief with sources, require an original contribution, and keep the final editorial judgment with a person.
Latest AEO & AI Search stories
Latest answer-engine articles

A useful standard
What this hub does—and does not—measure
AI answers vary by platform, query, location, account state, and time. A citation is an observation in one answer context, not a permanent ranking.
Eligibility is the first gate
A page still needs ordinary crawlability, indexability, useful content, and accessible text before any answer system can evaluate it.
Evidence creates inspectability
Primary sources, precise entities, dates, methods, and visible limits make a claim easier for readers and systems to check.
Retrieval is not causation
Referral and citation reports can document appearance. They do not prove why one source was selected or guarantee the next answer.
