Where Is the URL Builder in Google Analytics?
The campaign URL Builder is not located inside Google Analytics.
It can be found on the Google Analytics Demos and Tools site, where you can find the builder, along with many other useful features that support the effective use of your Google Analytics platform.
The site is freely available to GA users and developers. You can use this link to go to the URL Builder for free to create manually individual tracking tags for your digital marketing campaigns, blogs, social media, email links and more.
