"average Google user spends only 4 and a half active minutes on Google search per day, spread over about 22 page views. That’s roughly 11 seconds of attention invested in each Google page view. It doesn’t sound like a lot, but next time you do a search, count to 11- it’s a long time. This weekend, we took a hard look at Pac-Man D-Day and compared it with previous Fridays (before and After Google’s recent redesign) and found some noticeable differences. We took a random subset of our users (about 11,000 people spending about 3 million seconds on Google that day) The average user spent 36 seconds MORE on Google.com on Friday.. Thankfully, Google tossed out the logo with pretty low “perceived affordance” – they put an “insert coin” button next to the search button, but I imagine most users missed that. In fact, I’d wager that 75% of the people who saw the logo had no idea that you could actually play it. Which the world should be thankful for."
