> First results for searching 'calendar': http://i.imgur.com/l3A5Wlh.png
Well in your screenshot it seems like you scrolled down on the "calendar" search results. I get some other random thing ahead of Google Calendar, in incognito or not.
It is really annoying (I too hate those things, I would have installed the app if I wanted the app), but the click through thing only happens once in my testing. Are you clearing your cookies regularly?
