# Google Ads

{% hint style="info" %}
This guide applies only when selling pre-orders through Purple Dot's own checkout. Pre-orders sold through the Shopify checkout benefit from the same tracking as your regular sales.
{% endhint %}

If your store has Google tags enabled in the theme and you enabled the Google Ads integration on the Integration settings page in the [Merchant Portal](https://www.purpledotprice.com/merchant-portal/integration), then the Purple Dot checkout will forward the `conversion` event to Google Ads.

This is a client side integration.

```
send_to: <the provided Measurement ID>,
value: <total pre-order amount>,
currency: <currency shopper paid in>,
transaction_id: <Purple Dot pre-order reference>,
