# Introduction

> Track ad-driven traffic, events, and conversions with the Thrad Tag or the server-to-server API.

Two ways to send data to Thrad:

* **[Tag](/advertisers/attribution/tag/install)** — a JavaScript snippet you add to your site. Captures page views, events, and conversions from the browser.
* **[API](/advertisers/attribution/server-api/events)** — server-to-server endpoints for sending the same events and conversions from your backend (bearer-token auth).

Most advertisers start with the Tag.

## Where to start

<CardGroup cols={2}>
  <Card title="Install the Tag" href="/advertisers/attribution/tag/install" />

  <Card title="Track a conversion" href="/advertisers/attribution/tag/conversions" />
</CardGroup>

You'll receive a **tag ID** from Thrad in the format `adv_<name>_<id>`. Wherever you see `<YOUR_TAG_ID>` in this guide, replace it with the one we sent you.
