Overview
Building a great website isn’t just about technology or design; it’s about understanding human psychology. Don’t Make Me Think by Steve Krug offers essential principles and guidelines on user experience (UX) and usability. This book isn’t just for developers and designers—it’s for anyone who wants to understand how users interact with digital products and how to make websites and applications more intuitive.
Introduction: Timeless Principles of Usability
Initially published in 2000, Don’t Make Me Think emerged around the dot-com boom. Despite rapid technological advancements, Krug’s usability principles remain relevant because human psychology changes slowly. This 2013 revised edition updates the book with modern examples while maintaining its core focus: making websites easy to use.
The Three Laws of Usability
Usability means that an average person can navigate a website easily to achieve their goal without unnecessary effort. Krug distills usability into three core laws:
1. Don’t Make Me Think
Every time a user has to pause and think about how something works, it creates friction. A website should be self-explanatory, with straightforward navigation and obvious calls to action. Clickable elements should be easily recognizable, and language should be simple and intuitive, avoiding industry jargon or confusing phrasing.
2. Make Every Click an Obvious Choice
The number of clicks isn’t as important as ensuring each click is effortless. Users should never feel uncertain about whether they’re making the right choice. Clear labeling, intuitive navigation, and logical page flow help users move seamlessly through a site. However, minimizing clicks isn’t always the best approach in high-value sales and complex products. A website must guide the customer through decision-making when selling intricate products or services, much like a salesperson would in person.
3. Cut Half the Words, Then Cut Again
Concise content improves usability. Remove unnecessary words to reduce distractions, make key information stand out, and minimize scrolling. The only exception is content-heavy pages such as news articles or blog posts.
Designing Usable Websites
How People Use the Web
People don’t read web pages in a structured, detailed manner. Instead, they:
- Scan rather than read the content thoroughly.
- Users make choices based on “satisficing“—a combination of satisfying and sufficing. Instead of analyzing every option, they pick the first reasonable solution that meets their needs, even if it’s not the best choice. They rely on instinct and past experiences rather than exhaustive research.
- Rely on intuition rather than deliberate analysis.
To accommodate these behaviors, websites should be designed for scanning, using clear visual hierarchies, well-structured content, and eliminating unnecessary distractions.
eCommerce Challenges
Product pages in eCommerce must strike a balance between providing enough information to sell the product while remaining simple enough for novice buyers. Bullet points, images, and infographics often work better than large blocks of text. Many category pages are under-optimized, typically presenting a simple grid of products without context or differentiation. Heat maps show that most users click on the first product, return to the category page, and then click the second product—an inefficient process. For complex products, filtering options often confuse users who may not understand the attributes. Instead of just listing products, a website should guide visitors through their buying journey, just as a salesperson would in person.
Most eCommerce sites rely heavily on shopping campaigns for traffic, meaning many visitors land directly on a product page without a broader context. A secondary call-to-action (CTA) is critical. While the primary CTA is often “Add to Cart,” adding a secondary option like “See the rest of our collection” or “Read Our Buying Guide” helps guide users and keeps them engaged.
Web Navigation
Website navigation is like searching for something in a large department store—except it’s even more challenging because users don’t benefit from physical space. Effective navigation should help users:
- Find what they are looking for quickly.
- Understand their current location within the site.
- Know what options are available at each point.
Key elements of good navigation include straightforward global and local navigation, visible search functionality, intuitive page names, and indicators like “You Are Here” markers.
The Home Page
A website’s home page is one of the most challenging pages to design because it needs to serve multiple functions, such as:
- Communicating the site’s purpose and hierarchy.
- Providing search functions and navigation cues.
- Highlighting key content, features, or promotions.
A well-designed home page sets expectations and provides a strong foundation for user interactions.
Usability Testing
Usability testing involves observing real people using a website to identify friction points and improve functionality. It should be conducted at all stages of development, from early prototypes to post-launch refinements.
While professional usability consultants can be hired, Krug emphasizes that even DIY usability testing can provide valuable insights. A great way to identify “low-hanging fruit” usability issues is to ask friends or family who don’t regularly use the site to complete a simple task, such as “Find and purchase a product.” Record their session through screen recording and ask them to verbalize their thoughts. Many businesses assume users navigate their websites in a structured way, but these informal tests often reveal surprising user behaviors.
If visitors don’t convert on their first visit, consider the next best action. Educating visitors can improve engagement, boost SEO, and establish expertise. Offering downloadable eBooks or interactive buying guides provides value and generates leads.
Additional Usability Considerations
Although usability principles remain similar across platforms, mobile usability presents additional challenges. Mobile-friendly design requires:
- Breaking down content into smaller, digestible chunks.
- Ensuring key actions are easy to perform on small screens.
- Making navigation even more intuitive.
Beyond usability, Krug also covers:
- Maintaining user goodwill.
- Practical solutions for common usability issues.
- Strategies for getting management buy-in on usability improvements.
- Best practices for mobile application design.
