Organising content for a website calls for designers to ask key questions on their planned Information Architecture (IA). Usability experts the Nielsen Norman Group (NN/g) broke down these problems, providing answers to the 3 most persistent questions many designers today struggle with when building sites.
How Many Categories do you Need?
The general rule of thumb is to have enough categories to show all the information offered on your site or app. However, what’s considered ‘enough’ will greatly depend on the content and intention of a site.
Most simple sites with a small range of content will usually do fine with a few categories. This minimalist approach helps users find the information they want as quickly as possible. Take for instance, Dyson’s website for their Airblade line of products (the Dyson Airblade is the company’s take on the quick hand dryer). The entire website has a solid IA scheme since all variations of the Airblade fit into 5 categories.

At the other end of the spectrum is RestroomDirect, a site that also sells hand dryers as well as a bunch of other fixtures for public bathrooms. Condensing all information on the site down to 5 categories makes it difficult for customers to find information on the company’s full range of products, which is why the site features 7 links in the top horizontal navigation, and 17 product categories in the vertical navigation. This combination allows users to easily access all relevant information on the site as efficiently as possible.
Both examples show the basic principle behind determining the appropriate number of categories in a website: go with what makes it easiest for users to access the information they need; don’t box yourself in by trying to hit a predetermined number.
Should you List Categories in Alphabetical Order?
Organising categories by a certain order is another issue frequently tackled by designers, many of whom feel that sorting categories alphabetically makes the most sense.
Unfortunately, there’s no one-size-fits-all approach to this problem, but what you can do is consider the following factors:
- What organising principle would be more meaningful than sorting alphabetically?
- Will visitors be familiar with the category names
- How many categories do you have?
More Meaningful Organising Principles
One approach that makes more sense than alphabetical organisation is frequency of use, which helps the majority of visitors on a site access the information they’re most likely looking for.
An example of this can be found on RightMove.co.uk, a property listing that has the categories For Sale and To Rent as the first two items in the navigation panel. This setup saves users a tremendous amount of time, since it makes sense to highlight content users are most likely to click on.
If you were to organise categories on this site alphabetically, you would get the unintuitive result below.
However, there are instances when alphabetical organisation is more efficient. If you have categories under just one label (e.g. product names or brand names), users naturally look for information they know, like a particular word—alphabetical organisation is more helpful in this situation.
Do you Need Hover Menus with Touch Devices
With the advent of mobile devices that rely on touch interfaces, UX designers are wondering whether sites should still have hover nav menus.
Hover activated menus are unwieldy for touchscreen users. Even with menus adapted for use with a tap instead of a hover, touchscreens are just too small to display an entire menu. This can result in problems scrolling the menu without deactivating it by touch something else on the page.
However, just because a part of your audience can’t use this feature, doesn’t mean you should withhold it from everyone else. Hover activated menus are still easy to use on conventional desktop interfaces.
The key here is graceful degradation: ensure that customers who can’t use hover activation still have a means of accessing your content. A good example of this setup can be found on the Fedex website, which provides both hover and tap options for all their users, whether on traditional desktop interfaces or touchscreens.

The mobile version of the Fedex site automatically replaces hover menus with a simpler tap interface
As always good website design is about taking in to account your audience and how you can get them to the information they are looking for quickly and easily. It is worth spending time in the initial concept phase on these types of questions to avoid costly redesign and coding later on. Need help with your site, want an objective review?
