While designing a landing page for a retail banking site that possibly has to display n pieces of data, I try to adopt the principle 'more is less' and when it comes to user having to assimilate 'cognitive heavy' information I'm trying to restrict it further. Is there a set of rules that can help/guide the designer determine the ceiling limit? I'm also considering the 'progressive disclosure' and not finding it good enough as the data has to be displayed upfront. Any suggestions?
Less is more? :p don't think in a website as a service catalog or brochure.. Just add the information and links that users will need! I always try to find the most frequent tasks (analytics helps a lot!) and design accordingly. Of course, you have many customer types, and have to analyze that first.
For exAmple..Tasks Like... Opening an account, check fees, enter the home banking, find closest atm.. Contact a representative.. Get quotes.. That should be on the visible and main navigation area if you know
Lastly, check abanca website! I much like the way they conceived the site
