Does size matter when converting site visitors?

A while back I shared the fascinating “Which Test Won?” case of a former client, Sony Creative Software. Today I played the guessing game with a different type of A/B test. It used Google’s Website Optimizer,¬†an amazing tool for multivariate testing.

The goal of one of the tests, shown below, was to see if the size of a call-to-action influences results.

It does, by an impressive 8 percentage points, but I won’t tell you which was the winner. What I will say is that, this time, my educated guess was dead wrong!

How about you?
