For the past few months, we've been experimenting with homepage designs like this and have run several live tests on the site. We do these live tests when we are making a change that we think may fundamentally affect how people use the site. Initially, some of the experiment findings had us concerned, but one thing we have learned through our tests is not to judge the outcome too quickly.
All in all, we ran approximately 10 variants of the fade-in. Some of the experiments hindered the user experience: for example, the variants of the homepage that hid the search buttons until after the fade performed the worst in terms of user happiness metrics. Other variants of the experiment produced humorous outcomes when combined with our doodles — the barcode doodle combined with the fade was particularly ironic in its overstated minimalism. However, in the end, the variant of the homepage we are launching today was positive or neutral on all key metrics, except one: time to first action. At first, this worried us a bit: Google is all about getting you where you are going faster — how could we launch something that potentially slowed users down? Then, we realized: we want users to notice this change... and it does take time to notice something (though in this case, only milliseconds!). Our goal then became to understand whether or not over time the users began to use the homepage even more efficiently than the control group and, sure enough, that was the trend we observed.
Internally, a large number of Google employees have been using the new homepage. They have come to really like it — it represents our focus on great search yet helps searchers efficiently access all of Google's products. Like the new supersized search box we launched several months ago, this change is one that is very noticeable at first, and then quickly becomes second nature. We hope you like it!
