The sign up button or link is an important call-to-action on the homepages of most web services. In a recent demo case Usabilla compared the sign up on the homepages of 10 different web services. Users found the sign up button on the Twitter homepage in 1.8 seconds. Animoto was a good runner up with 2.3 seconds. On average it took participants 3.5 seconds to find a way to sign up for these web services.
The differences between the performance of these websites on this important task are big. But what makes Twitter homepage stand out in this test? Why do the sign up buttons at Animoto, Vimeo and MyNameisE catch attention faster than those of Wakoopa, Basecamp, and PayPal? We would love to hear your opinion about these test results.
