"Screenview URLs", or client-side only URLs, are when Single Page App scripts update/change the URL but there is NO network or server call to that URL. For those of your users that may use "Page URL" to search in Tealeaf, this will return ZERO results. However, there is a fix! The Tealeaf UIC/JS captures these URLs as a "Screenview LOAD" event. You can create an event to evaluate this occurrence, and make it searchable in the Portal (Event Values parameter). See the attached Edit Event screen capture for details. This can be another good differentiator from server logs, as Tealeaf will catch things like "/error" pages that may only show up on client side.
