The Metrics Library is reserved for Pro accounts and above. Sign in if you already have one, or upgrade to unlock all 90+ metric definitions used inside the 3LA framework.
Every metric defined with methodology and limitations
The Metrics Library documents every measurement in the 3LA platform. Each definition distinguishes between a readiness score (diagnostic) and an observed event (citation, mention, referral). Sample size requirements and known limitations are stated for each metric.
Read the denominator before comparing
Citation rate, mention rate and search click-through rate count different events. Check the population, reporting period and minimum sample whenever a percentage is used to justify an editorial decision.
Frequently Asked Questions
What is the Metrics Library?
Documents every metric: what it measures, calculation method, sample requirements and limitations.
What is the difference between citation and mention rate?
Citation = source-attributed link. Mention = brand name regardless of attribution. Different measurements.
What is a confidence band?
Statistical range based on sample size. Always displayed so you know the precision.
Is Layerscore a guarantee of citation?
No. It is a diagnostic readiness score. Actual citations depend on model, prompt and retrieval context.
Can I access individual metric pages?
Yes. Each metric has a dedicated page with methodology, requirements and glossary links.
