The Proof Ledger

RankEcho re-tests the exact prompts customers fix, on a schedule, and records whether the citation appeared. This page will publish the aggregate outcomes - reportable wins, median days to first citation, and the retrieval-vs-training pathway split. Until the dataset clears its publishing threshold, the methodology below is the page.

Collection context: 5 measured prompts and 0 reportable wins are currently stored. Both thresholds must be met before figures publish.

A tracked prompt counts as an observed win when the exact prompt - re-run on a schedule after a fix shipped - returns at least one citation of the tracked brand. It only graduates to a reportable win when sampling reaches medium confidence (at least 3 post-ship runs) and the post-ship citation rate beats that prompt's own pre-ship baseline.

First citation within 3 days of shipping is classed as a fast retrieval (RAG) effect; 14 days or later is classed as a slow training-cycle effect; in between is recorded as unknown.

• These are correlation-with-controls observations, not causal guarantees. AI answers vary by engine, model version, retrieval state, time, and wording.
• The sample is self-selected: prompts that RankEcho customers chose to fix and track.
• Figures stay withheld until at least 25 measured prompts and 10 reportable wins exist.
• No customer-level results, domains, or prompts are ever published here - aggregate counts and medians only.

Aggregate counts and medians only. This page never publishes customer-level results.
