Which Headline Converted 30% Better?

37Signals used Google Website Optimizer to randomly rotate five different headline and subhead combinations on the signup page.

They measured the number of clicks on any green “Sign Up” button. They ran the test for 4000 page views, because the numbers didn’t change much after about 3000 page views, so they stopped at 4000.

So which ad converted 30% better than the original?

The answer….

Test ad #1 performed 30% better than the original. Test ad #2 performed 27% better; test ad #3 performed #15% better; and test ad #4 performed 7% better than the original.
