To ensure that the new Search Ads 360 can measure all of your conversions regardless of the browser that your site visitor is using, use the Google tag (gtag.js) as the format for your Floodlight conversion action tags.
The Google tag sets new cookies on your domain, which stores a unique identifier for a user or the ad click that brought the user to your site. These cookies are refreshed when a user visits your site before the cookie expires. The cookies receive ad-click information from a GCLID (Google click identifier) parameter that's included in the conversion tracking tags.
Since Natural Search in the new Search Ads 360 involves using information from new cookies that are set on your domain, be sure to provide users with clear and comprehensive information about data collection and obtaining consent where legally required. Learn how to opt out of setting first-party cookies on your site’s domain.
Google tag benefits
- Faster and easier integration with other Google products
- Use the Google tag for Google Marketing Platform products and other products, such as Google Ads and Google Analytics,. If you use these products, the Google tag makes website implementation easier by providing a unified tagging experience.
- More accurate conversion tracking
- Use the Google tag to set new cookies on your domain, which store a unique identifier for a user or the ad click that brought the user to your site. This means Floodlight can measure conversions more accurately.
If you use Floodlight iframe or image tags, Google recommends you migrate to the Google tag or use Google Tag Manager with the Conversion Linker to measure conversions more accurately. You also benefit from the latest dynamic features and integrations as they become available.
How the Google tag works
A Google tag for Floodlight comprises two JavaScript snippets:
- A global snippet
- An event snippet
Global snippet
The global snippet should be placed in the <head> section of your HTML pages on all of your website's pages.
Here's an example of the global snippet in a Google tag:
<!--
Start of global snippet: Please do not remove
Place this snippet between the <head> and </head> tags on every page of your site.
-->
<!-- Google tag (gtag.js) - DoubleClick -->
<script async src="https://googletagmanager.com/gtag/js?id=DC-1234567"></script>
<script>
window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments)};
gtag('js', new Date());
gtag('config', 'DC-1234567');
</script>
<!-- End of global snippet: Please do not remove -->
This code snippet is only an example and won’t work on your website.
When you set up a Floodlight conversion action, you're able to view and copy the Google tag for your account. Learn more about the fields and other information in a global snippet.
Event snippet
The event snippet should be installed on the page with the event you're tracking. It can be placed anywhere on the page after the global snippet. For the best tracking accuracy, place the snippet within the <head> section, just after the global snippet.
Here's an example of an event snippet:
<!--
Event snippet for Thank You on http://example.com/thanks: Please do not remove.
Place this snippet on pages with events you’re tracking.
Creation date: 11/01/2017
-->
<script>
gtag('event', 'purchase', {
'allow_custom_scripts': true,
'value': '[Revenue]',
'transaction_id': '[Order ID]',
'send_to': 'DC-1234567/group1/thank123+transactions',
'u1': '[Custom Floodlight variable]'
});
</script>

ord=[Order ID]?" width="1" height="1" alt="">

<!-- End of event snippet: Please do not remove -->

When you set up a Floodlight conversion action, you are able to view and copy the event snippet for your account. Learn more about the fields and other information in an event snippet.
Using the Google tag for multiple Google products
The Google tag can be configured to send data to multiple Google products. For example, if you use Google Analytics, Google Ads conversion tracking, and the new Search Ads 360, you only need one Google tag on every page of your site. For each product, add a 'config' command to the global snippet, so Google knows how to route your data. Each conversion or event you want to track has its own event snippet. Learn how to use a Google tag that tracks conversions for both the new Search Ads 360 and Google Ads.
Cross-domain conversion tracking
You can enable cross-domain tracking to measure activity across multiple domains (such as when your landing page domain is different from your conversion domain), Add a set linker command to the Google tag on pages in your landing domain that can send visitors to your conversion domain. Learn more about cross-domain conversion tracking.
How to opt out
If you don’t want the Google tag to set first-party cookies on your site’s domain, add the highlighted portion below to your global snippet’s config command. Google doesn't recommend this method, as it leads to less accurate conversion measurement.
gtag('config', 'DC-1234567', {'conversion_linker': false});
How are Google Tag Manager and Google tag different?
Google Tag Manager and Google tag are separate, independent ways of tagging your website. If you want to manage Google and third-party tags from a single location without modifying your site’s code in the future, use Google Tag Manager. If you want to code tags on your site directly using JavaScript, use the Google tag.
