I implemented a custom script in tankyou page in my woocommerce store to track google ads conversions. This is my implementation:
add_action( "woocommerce_thankyou", "pixel_analytics_conversion_track_script", 20 );
if ( ! function_exists( 'pixel_analytics_conversion_track_script' ) ) {
function pixel_analytics_conversion_track_script( $order_id ) {
if ( $order_id > 0 ) {
$order = wc_get_order( $order_id );
if ( $order instanceof WC_Order ) {
$order_id = $order->get_id(); // order id
$order_key = $order->get_order_key(); // order key
$order_total = $order->get_total(); // order total
$order_currency = $order->get_currency(); // order currency
$order_payment_method = $order->get_payment_method(); // order payment method
$order_shipping_country = $order->get_shipping_country(); // order shipping country
$order_billing_country = $order->get_billing_country(); // order billing country
$order_status = $order->get_status(); // order status
?>
<script type="text/javascript">
jQuery(document).ready(function( $ ){
console.log('PURCHACE EVENT');
/* Track conversion on facebook Pixel */
fbq('track', 'Purchase',
{
value: <?php echo $order_total ?>,
currency: "<?php echo $order_currency ?>"
});
/* Track conversion on Google Ads */
gtag('event', 'conversion',
{
'send_to': 'AW-693771414/0MhwCMa9rLYBEJa56MoC',
'value': <?php echo $order_total ?>,
'currency': "<?php echo $order_currency ?>",
'transaction_id': "<?php echo $order_id ?>"
});
});
</script>
<?php
}
}
}
}
The code works very well but some data is not precise and I think that probably the code above duplicates conversion if user goes to thank you page twice. We have an order confirmation email that has a link to the thankyou page of woocommerce.
As you can see Im sending the transaction_id
parameter, so my question:
If the user loads twice or N times the thank you page the conversion will appear dupplicated in Google ads even if you send the transaction_id
parameter?
Update: Added compatibility for HPOS
You can use order custom metadata to avoid duplicated Conversion tracking as follows:
add_action( "woocommerce_thankyou", "pixel_analytics_conversion_track_script", 20 );
if ( ! function_exists( 'pixel_analytics_conversion_track_script' ) ) {
function pixel_analytics_conversion_track_script( $order_id ) {
$order = wc_get_order( $order_id ); // Get order object
// Avoid if pixel analytics conversion track script has been run before
if ( is_a($order, 'WC_Order') && !$order->get_meta('_pixel_tracking') ) {
$order_id = $order->get_id(); // order id
$order_key = $order->get_order_key(); // order key
$order_total = $order->get_total(); // order total
$order_currency = $order->get_currency(); // order currency
$order_payment_method = $order->get_payment_method(); // order payment method
$order_shipping_country = $order->get_shipping_country(); // order shipping country
$order_billing_country = $order->get_billing_country(); // order billing country
$order_status = $order->get_status(); // order status
?>
<script type="text/javascript">
jQuery(document).ready(function( $ ){
console.log('PURCHACE EVENT');
/* Track conversion on facebook Pixel */
fbq('track', 'Purchase',
{
value: <?php echo $order_total ?>,
currency: "<?php echo $order_currency ?>"
});
/* Track conversion on Google Ads */
gtag('event', 'conversion',
{
'send_to': 'AW-693771414/0MhwCMa9rLYBEJa56MoC',
'value': <?php echo $order_total ?>,
'currency': "<?php echo $order_currency ?>",
'transaction_id': "<?php echo $order_id ?>"
});
});
</script>
<?php
// Flag the order (with custom meta data) to avoid pixel analytics conversion track script run multiple times.
$order->update_meta_data('_pixel_tracking', true);
$order->save();
}
}
}
Code goes in functions.php file of the active child theme (or active theme). It should works.
