I am bit confused on which approach to take, the issue is we have 2 major sections, one is asking for user profile information - just 4 optional fields and the other is about user preferences to receive specific newsletters based on the preference selected.
My question is it worth dividing the form into a multiple step progressive approach when all the fields we require the user to fill fit in a single page and for most of the browsers in the first scroll. In the past when we moved to a single pager from a progressive approach for a business directory we got a 15-20% increase in the conversion.
The flow is: User enters information just email and name and signs up for a news letter. After successful sign up, should we present: 1. A single page having both the sections profile info(4 fields) and preferences OR 2. 2-3 steps dividing profile, password and preference into 3 steps
Is it worth dividing a single step into 2-3 steps just for 4 optional extra fields ???
