One of the events automatically tracked through Enhanced Measurements is click, which can represent any click made by the user but with this default tracking represents someone clicking a link that goes to a website that’s not the current one.

How does Google know what your current website is? The basic check is the domain that the user is actually on in the URL bar (eg. mysite.com.au). However, if your brand spans multiple domains, you should probably define them in your tracker’s settings. Google will then
try to track users across those domains, but it also won’t count clicks between those domains as external. This can help reduce the amount of extraneous data.

Note that for this tracking to work, the user has to click a link on a website that actually points to a different URL. Some websites use redirects for outbound clicks. For example, if I’m on mysite.com.au and the page links to anothersite.com.au, the actual URL is https://mysite.com.au/out/anothersite.com.au. Enhanced Measurement then won’t pick that up and you’ll need to tag that up manually.

The click event tracks a few different dimensions:

• Link domain: The domain of the website your page links out to.
• Link URL: The full URL of the website your page links out to.
• Link classes and link ID: The HTML classes and ID of the link clicked. This can sometimes be used to differentiate between multiple links from the same page to the same page.

The most top-level question for you to analyse is what are the top domains that users from your website are clicking to. This helps you work out where you are sending traffic and potentially adjust your content and marketing accordingly.

The other useful question is what are the actual top URLs you’re sending traffic to.

Finally, you might find some URLs that start with tel: and mailto:. These are click-to-call and click-to-email links on your website. They often represent high intent so you could even set these up as conversions.
