Method status: NRLC treats these as separate observable stages, not as a causal attribution model.

Under this method, referral sessions are downstream events. An observed answer may display source attribution without generating a referral click. Track citations and mentions on the prompt log; treat clicks as a separate, optional downstream event.

## Attribution ladder

- Source citation: the saved answer visibly attributes a URL or domain.
- Entity mention: the monitored entity appears without source attribution.
- Referral click: analytics records a visit from an identifiable answer surface.
- Business outcome: a separately measured conversion or offline result occurs.
Report each stage independently. A source citation is evidence of visible attribution in that observed answer; it is not proof of a click or business outcome. A mention without a citation does not identify the retrieved source.

## Zero-click reporting

For each prompt, retain the answer, source attribution, engine, interface, and date. Aggregate source citations with the same C / P convention used by the citation-tracking guide. Keep referral sessions and conversions in separate columns, and use “unattributed” when no defensible link exists.

## Limitations

This method measures observed outputs, not private model reasoning. Results can vary by engine, interface, prompt wording, account state, and time. A citation occurrence does not prove that a source caused an answer, produced a click, or generated revenue. NRLC has not published a worked citation-rate example because there is not yet an observation log with a prompt count, engine, dates, citation count, or citation rate. A missing visible citation cannot prove that a page was not used internally by an engine.

## Evidence

Method

NRLC AI Search Measurement method

Observation window

Declared per measurement run; no aggregate run is claimed by these method pages.

Dataset

Versioned prompt set and answer-observation log supplied by the operator

Method

Freeze prompts, name the engine and interface, classify observed citation and mention outcomes, preserve exclusions, then calculate C / P over eligible prompts.

Confidence

first-party operational convention; not asserted as an industry standard

Limitations

Observed outputs vary by engine, interface, prompt wording, account state, and time. The method does not expose private model reasoning or establish causal attribution.
