# Introduction

Importing data into Yandex Metrica offers you more comprehensive insights into users or traffic sources from your tag. This can help you associate user actions on the site with their activity off the site, build end-to-end analytics, or assess your expenses across different traffic channels, significantly expanding your data analysis capabilities.

## Importing offline conversions {#offline-conv}

Importing offline conversions allows you to transmit data about user actions outside the site, such as paying for services after filling out a site form. This data can be attributed to site sessions, helping you build end-to-end analytics and optimize your advertising efforts.
