As of 16 March 2010, Google Analytics has being displaying homepage views as “/” rather than “/index.html”, “/index.php” etc. I have reviewed a number of client accounts on different hosting platforms and the problem exists for them all.
This situation typically occurs in Google Analytics accounts where a default homepage (e.g. index.html) has not beenĀ specified for a profile. However in this instance the problem is occurring in long-established accounts. The problem is most likely on Google’s side. Hopefully it will be rectified shortly.
