It is important to test and adjust your IA to make sure you are meeting the needs of most of your users.

To test IA, you ask users where they would search for particular types of content in your content categories and subcategories. This testing can be done in the form of scenarios (eg You are a parent trying to find out if the HPV vaccine is safe – where do you look for that information?; You are trying to find the bus timetable for Wollongong – what would you select?).

If users have trouble finding content, this is a sign you need to change your IA. You can think about changing:

• the structure – maybe the grouping is not what users expect
• the heading – maybe the label is not clear enough or the wording is not what users would commonly use.

Keep testing and updating until most users can find what they need.
