URL channels track individual pages, or groups of pages, based on the directory structure of your site.
By entering a full or partial URL, you can begin tracking its performance. The performance of all the pages below the URL you entered will also be included and reported but not as individual line items. If you want to track individual URLs, you need to add them separately in your URL channel.
URL channels don't require changes to your code, so once you've created a URL channel, it will track automatically and almost immediately.
