Websites require a lot of time, effort and money. Probably more than most people think. It’s not just technical things like development and hosting. Anyone involved in commissioning, writing or editing content is spending valuable time to help publish stuff. Over the course of a year this effort could be many thousands of hours of staff time, and many hundreds of thousands of pounds. A content audit will help you understand the size and shape of the thing everyone’s working on, so you can use resources more effectively.
Ask your users how you could improve your website. It’s likely one of their top answers will be: ‘make things easier to find’. It always is. But it’s hard to organise information into a sensible, logical structure that works for all users. And it’s virtually impossible if you don’t have a map of the thing you’re trying to restructure. The content audit is your map.
