Google is now making page view data publicly available on the uptake of widgets in its directory. However, it is only releasing statistics broadly for widgets that consumers have added to their own web pages, not the Google Personalized Homepage. The most popular widget (which Google calls gadgets) is for Google Maps. It generated 4.8M weekly page views.
In addition, Google now gives developers the ability to track both page views and interactions using Google Analytics. Hopefully Google will start to release more of this information publicly the way it does for videos that are on Google Video.
