One of the problems I see with some non-profit websites is that they are hard to navigate and not intuitive. Overall, they lack a clear path for visitors. 

So how do you fix your site’s navigation so that users can get the information they need while nudging them in the direction you want them to take?

A tool we like to use for quickly organizing content is card sorting. We use it for designing a website’s architecture and navigation paths. We can use card sorting to find out how people think the content should be organized and get the user insights to make informed information architecture decisions.

What is card sorting?

Card sorting is a well-established research technique for discovering how people understand and categorize information. You can use card sorting results to group and label your website information in a way that makes the most sense to your audience.

I won’t go into details on how to conduct a card sort experiment as they are lots of sources available already like the one below.
