Single-page sites (or single-page apps) typically have just one page load. When navigating the site, subsequent content is either uncovered from the DOM, where it’s been in a hidden state, or loaded from the server using HTTP requests that do not invoke a new page refresh. This behavior, however, has some implications for Google Analytics tracking, especially when configured via Google Tag Manager.
The crux of the problem is this: When you create a Google Analytics tracker, the URL of the page (without a possible #hash) from when the tracker was created is sent as the value of the Document Location field with every hit that uses this tracker.
