Why Are Google Ads Enhanced Conversions Important?
Standard conversion tracking helps Google Ads record when someone completes a form. Enhanced Conversions can improve conversion matching by securely using eligible first-party customer data, such as email addresses, when available and permitted.
This can help you measure lead-generation performance more accurately and give Google Ads better conversion signals for campaign optimization.
Formidable Forms Tracking Code
To track form submissions reliably, you need to identify when the form has been successfully submitted and make the relevant form data available to GTM.
<script>
(function() {
var origXMLHttpRequest = XMLHttpRequest;
function pushFormidableEvent(formIdentifier, requestBody) {
var cleanedRequestBody = mapFormFields(requestBody);
if (isFormValid(cleanedRequestBody)) {
cleanedRequestBody.form_id = formIdentifier || 'default_form';
var eventToFire = 'formidable_form_fired';
if (!dataLayerContainsEvent(eventToFire)) {
window.dataLayer = window.dataLayer || [];
window.dataLayer.push({
event: eventToFire,
inputs: cleanedRequestBody
});
}
}
}
XMLHttpRequest = function() {
var xhr = new origXMLHttpRequest();
var origOpen = xhr.open;
var origSend = xhr.send;
var requestUrl = '';
xhr.open = function(method, url) {
requestUrl = url;
return origOpen.apply(this, arguments);
};
xhr.send = function(data) {
if (data instanceof FormData && requestUrl.includes('admin-ajax.php')) {
var requestBody = {};
data.forEach(function(value, key) {
requestBody[key] = value;
});
pushFormidableEvent(requestBody['form_key'], requestBody);
}
return origSend.apply(this, arguments);
};
return xhr;
};
function mapFormFields(inputs) {
return {
first_name: inputs['item_meta[17]'] || '',
last_name: inputs['item_meta[18]'] || '',
email: inputs['item_meta[3]'] || '',
phone: inputs['item_meta[16]'] || '',
message: inputs['item_meta[5]'] || ''
};
}
function isFormValid(inputs) {
return inputs.first_name && inputs.email && inputs.phone;
}
function dataLayerContainsEvent(eventName) {
return (window.dataLayer || []).some(entry => entry.event === eventName);
}
document.addEventListener('submit', function(event) {
var form = event.target.closest('form');
if (form && form.getAttribute('id') === 'form_contact-form') {
var formData = new FormData(form);
var requestBody = {};
formData.forEach(function(value, key) {
requestBody[key] = value;
});
pushFormidableEvent(formData.get('form_key'), requestBody);
}
}, true);
})();
</script>
