# Engagement Attribution for SANs

> Branch supports engagement conversion metrics across a range of ad partners, giving you comprehensive insights and control over the full range of available ad engagement touch types.

Branch supports **engagement** conversion metrics across a range of ad partners, giving you comprehensive insights and control over the full range of available ad engagement touch types. This guide describes which engagement types each partner supports and how to view engagement attribution in Branch and in your exports.

## Overview

Engagement attribution lets you measure conversions that originate from ad engagement touch types (such as an engaged view or an engaged click), in addition to standard clicks and views. Branch exposes this through the `touch subtype` metric.

- Touch subtype is available in Branch via [Ads Analytics](https://help.branch.io/marketer-hub/paid-ads-analytics.md).
- Touch subtype is available in [Export APIs](https://help.branch.io/apidocs/index.md).
