So Facebook updated their login page. I couldn't help but wonder the reason behind having a Sign Up button in the header when there already is a Sign Up form in the body section.

What aspect of UX does it improve?

    I think Facebook is A\B testing its login page to see if it can drive greater conversions.

  • If you want the real answer you might try Quora to get somebody on the Facebook design team. Other answers would fall under speculation.

1 Answer 1


Are you still seeing that? I see no such "Sign Up" button at the top, only a "Log In" button.

enter image description here

which makes me think it may have been a temporary glitch or oversight.

    Facebook is known to roll out features/improvements in an iterative manner. E.g. They start with 1% of their user base. Nothing crashes? Up to 2%. Etc Commented Aug 3, 2016 at 7:59
