# Session

Glossary · Analytics

Canonical page: https://datasdk.ai/glossary/session

A session groups website interactions within a defined period using a measurement system's rules.

## Why it matters

Understand how a reported visit differs from an individual page view.

## Illustrative example

An analytics tool groups several page views into one session.

## What to check

Session rules vary; a session is not proof of a unique person.

## How Data SDK fits

Data SDK connects website visits with available company details worldwide, from startups to larger businesses. Coverage and fields vary. Start free trial opens an email request; terms are confirmed with the team. The full API is coming soon.

These are suggested workflows, not a list of built-in integrations. Use your own approved analytics, CRM, and research process where needed. Matches and fields vary. A company match does not identify a person or prove buying intent.
