Short answer
There are four types of analytics. Descriptive tells you what happened. Diagnostic explains why it happened. Predictive estimates what is likely to happen next. Prescriptive recommends what you should do. Most beginners start with descriptive and diagnostic work, and value grows as you move toward prediction and clear recommendations.
The four types
- Descriptive: what happened? The site had 12,000 sessions last month.
- Diagnostic: why did it happen? Sessions fell because a top-ranking page dropped in Google.
- Predictive: what is likely to happen? Based on past seasons, traffic should rise 30% in December.
- Prescriptive: what should we do? Raise holiday ad budget two weeks early to catch rising demand.
