The default purpose of the Tracking Code was to track which pages are viewed by your visitors. You can build rules in Center based on these visits. For example, if a user visits a Product Page, but does not visit the Checkout Page, then send them an email to follow-up.
The default Installation Snippet includes tracking the visit to the current page by calling
center('YourSiteName.send','view');. If you do not wish to track a given page, simply remove this command.
Websites using client-side rendering (tools like Angular or React) will not have traditional page views. Move the call to
center('YourSiteName.send', 'view') into your page rendering logic so that it is executed on major screen changes, or however you want to track visitor navigation.
