How to include website domain in GA4 Google Analytics?

[Charlotte]

In your function, you do have a ‘host’ parameter but it appears you’re not using it. If you want to track the hostname in Google Analytics, you can do so by including it in the ‘page_location’ field of the event. This field is meant to track the full URL including the domain ( hostname ). You can combine the host and the page path like this – host + pagePath, which gives you the full URL. Your code would look like this:

function pageViewGa(pagePath, pageUrl, host) {
    gtag("event", "page_view", {
        "page_title": pagePath,
        "page_location": host + pagePath,
        "page_path": pagePath
    });
}

This way, you will be tracking the hostname on Google Analytics.

You’re on the right track. It seems like you already have the “host” as a parameter in your function, but you’re not using it in the properties that you’re setting for the gtag pageview event. To track the hostname, you can simply append the hostname to the “page_path” and “page_location” properties.

For “page_location”, ideally, it should contain the complete URL such that it includes the protocol (http or https), hostname and path.

For “page_path”, it encompasses the page’s path and other information that comes after the domain name in the URL, you can add the hostname too for your reference.

Here’s how to do it:

`javascript
function pageViewGa(pagePath, pageUrl, host) {
gtag(“event”, “page_view”, {
“page_title”: pagePath,
“page_location”: host + pageUrl,
“page_path”: host + pagePath
});
}
`
Just replace “pageUrl” and “pagePath” with your “host + pageUrl” and “host + pagePath” respectively, this will contain your hostname.
Remember to make sure that “host” contains the correct value. If it doesn’t, you can get it from “window.location.hostname” in JavaScript.
