# Analytics Study Guide

Marketing analytics turns data into evidence for decisions. Reliable analysis starts with clear objectives, consistent definitions and trustworthy collection—not with a dashboard full of charts.

## Learning outcomes

- Translate business objectives into measurable KPIs.
- Describe events, parameters and conversions.
- Interpret traffic sources and campaign tags.
- Understand attribution limitations.
- Calculate and communicate core performance metrics.

## Measurement workflow

1. State the business question and decision the analysis should support.
2. Define the outcome, metric, numerator, denominator, time window and segments.
3. Document event names, parameters, conversion rules and ownership.
4. Validate implementation using test journeys and reconciliation checks.
5. Analyze trends and segments, checking sample size, seasonality and data quality.
6. Communicate findings, limitations and recommended next steps.

## Core formulas

- **CTR** = clicks ÷ impressions × 100%.
- **Conversion rate** = conversions ÷ stated eligible interactions × 100%.
- **Average CPC** = spend ÷ clicks.
- **CPA** = spend ÷ conversions.
- **ROAS** = attributed revenue or conversion value ÷ ad spend.
- **Marketing ROI** depends on the organization's definition; a common form is (incremental profit attributable to marketing − marketing cost) ÷ marketing cost × 100%. State the definition and cost basis.

## Reporting cautions

Check time zones, currency, duplicate events, missing tags, consent effects, channel grouping and changes in tracking. Attribution assigns credit according to a model; it does not by itself prove that a channel caused the outcome. Use experiments or other causal methods when the decision requires incremental impact.

## Practice task

Create a simple report for a campaign with spend, impressions, clicks, conversions and conversion value. Calculate CTR, CPC, conversion rate, CPA and ROAS; identify at least two data-quality checks and one limitation.
