For some time now we’ve had two different email newsletter sign up forms here on Baymard. The hypothesis was: The traditional “sidebar sign up form” have no space for explaining benefits + It doesn’t capture readers as well because it’s not placed right after the user has finished reading an article.
So we’ve also had an inline call-to-action box for newsletter sign up, placed right at the end of each article:
Our assumption was that the premium placement and the possibility to write some explaining copy would make the inline sign up form generate most of the new email subscribers.
Over the last year the sign up distribution has been 35% for the inline form and 65% have used the sidebar form. This was surprising because there isn’t any real copy in conjunction to the sidebar sign up form, and it requires the reader to scroll to the top - so “feature wise” the inline should have the upper hand. The sidebar sign up however have the benefit of having the same placement on most blogs throughout the last decade. Most web savvy users will instinctively look for it there.
This distribution, once more, tells us just how much a user’s assumptions and expectations from other sites will impact how your site is used. So while you can radically rethinking site structure, web conventions still rule.
