This brings another interesting fact, SiteCatalyst provides Single Access Visits but Discover has Single Page Visits. Did you notice the difference? Yes, its Access vs Page. So are these 2 metrics different?
Difference is a little more than just metric labelling, as I explain below:
Discover defines a single page visit as a visit where only one server-call being made by the visitor....while SiteCatalyst considers a single access as only one page being visited..... ahhh please clarify more.
It is possible to visit only a single page but still have multiple server-calls if:
- page is reloaded
- AJAX calls on page which are Omniture tracked
So as a result, Discover may have lower number of Single Page visits than SiteCatalyst and hence lower bounce rate for a single page.
So what should we use? Good question (yeah, asking questions is good), I suggest using SiteCatalyst as its Single Access visit is closer to definition of a bounced visit by WAA : -For a bounced visit, the entry page and exit page are the same page. Discover, even if a same page is entry and exit page, will not consider it a bounced visit because of reasons explained above.
