A sidebar can be a very diverse piece of a website and typically appears on the majority of a site’s internal pages. A sidebar is used to house important pieces of information that an organization doesn’t want to get lost within the body. It’s vital that this space be used wisely. If it becomes too cluttered, it’s less and less effective.
In a sidebar, you may find additional navigation, pertinent CTAs, upcoming events, or even just additional bits of highlighted content. But navigation again? Yes! It’s smart to make it as easy as possible for users to find the content you’ve worked so hard to thoughtfully put together.
