Book Review: Prioritising Web Usability

I can't recommend this book enough. A lot of the topics covered in this book are common sense. As a Web developer or designer you may think you create very usable sites already, but even if this is true, and you are a true usability guru, a lot of the facts and statistics in this book are useful for backing up your views, and getting your point across to clients who insist on functionality that you know full well will break usability conventions, and potentially harm their finished Web site.

The book is for people who have business goals for their Web sites or the Web sites they work on. This includes sites that match the following criteria:

  • E-commerce sites
  • Corporate sites
  • News sites
  • Non-profit organisations
  • Government agencies

If you are trying to get users' to accomplish something when they visit your site then you should be concerned about usability.

This book contains the results of many studies into how people behave on the Internet and consequently what makes Web sites succeed or fail.

This book alone is not enough to ensure your site will be the most usable it can be, but it is crammed full of tips and real world examples of what to do, and what not to do when it comes to designing Web user interfaces, writing Web copy and planning your Information Architecture. Ideally you will need to perform usability testing as well, but the information in this book will significantly help in improving your Web site.

The book begins by explaining how people use the Web and how to optimise your site accordingly. It explains how users' use search engines to find answers to problems, and how to improve your site to cash-in on these users.

Nielsen and Loranger then go back to the usability problems they found back in 1994 and discover what significant usability issues are still relevant today, including bugbears such as:

  • Breaking the back button
  • Pop-ups
  • Flash
  • Uncertain clickability
  • Plug-ins
  • Splash pages

The forth chapter helps you prioritise your Web site usability issues and decide what to tackle first. They do this by categorising usability problems by severity, frequency, impact and persistence.

Site search engines and their user interfaces and results pages (SERPS) are covered next, including a brief introduction to Search Engine Optimisation.

Chapters 6 and 7 concern navigation, information architecture, readability and legibility. This is followed by a chapter on how important it is to specifically write for the Web, using summaries for key points, and by using simple language. The importance of knowing your audience and how people skim read articles on the Web is talked about, as is the use of marketing slogans and hype.

The following chapter is geared towards your e-commerce goals. How to provide good product information and win consumer confidence in your site and product to increase and promote sales.

The penultimate chapter looks at presentation and users' expectations, while the final chapter in the book is all about balancing technology with people's needs. This covers the use of multimedia content such as videos and the use of familiar interface conventions in Web design.
