Sobre esta ferramenta
Use demographic_share to turn marketing metrics into decisions: cost, volume, efficiency and scenario comparison.
Marketing has many 'quick calculations', but assumptions (universe, window, attribution) change everything. Full mode makes it explicit.
Como usar esta ferramenta
- Fill in scenario data (spend, impressions, clicks, conversions, revenue).
- Confirm period and metric definition.
- Compare alternatives (two CPMs, two rates, two scenarios).
- Copy the result to briefs, reports or media plans.
Perguntas frequentes
Are CPM/CPC/CPA comparable across channels?
Carefully; channels differ in definitions, quality and attribution.
Common marketing math mistakes?
Mixing windows/periods, wrong base (reach vs impressions), ignoring attribution.
Does this replace BI?
No. It helps simulate and understand; BI validates and refines.
Technical notes
Fórmula usada: Participação do segmento (%) = (Segmento ÷ Total) × 100.
Unidade e escopo: dividimos o volume do segmento pela base total e multiplicamos por 100 para obter a participação percentual.
Fonte: Observação: prática comum; garanta que segmento e total sejam do mesmo período e universo.
