Usability and the utility, not the visual design, determine the success or failure of a website. Since the visitor of the page is the only person who clicks the mouse and therefore decides everything, user-centric design has become a standard approach for successful and profit-oriented web design. After all, if users can’t use a feature, it might as well not exist.
We aren’t going to discuss the design implementation details (e.g. where the search box should be placed) as it has already been done in a number of articles; instead we focus on the main principles, heuristics and approaches for effective web design — approaches which, used properly, can lead to more sophisticated design decisions and simplify the process of perceiving presented information.
Please notice that you might be interested in the usability-related articles we’ve published before:
In order to use the principles properly we first need to understand how users interact with websites, how they think and what are the basic patterns of users’ behavior.
Basically, users’ habits on the Web aren’t that different from customers’ habits in a store. Visitors glance at each new page, scan some of the text, and click on the first link that catches their interest or vaguely resembles the thing they’re looking for. In fact, there are large parts of the page they don’t even look at.
Most users search for something interesting (or useful) and clickable; as soon as some promising candidates are found, users click. If the new page doesn’t meet users’ expectations, the Back button is clicked and the search process is continued.
Web users are impatient and insist on instant gratification. Very simple principle: If a website isn’t able to meet users’ expectations, then designer failed to get his job done properly and the company loses money. The higher is the cognitive load and the less intuitive is the navigation, the more willing are users to leave the website and search for alternatives. [JN / DWU]Users don’t make optimal choices. Users don’t search for the quickest way to find the information they’re looking for. Neither do they scan webpage in a linear fashion, going sequentially from one site section to another one. Instead users satisfice; they choose the first reasonable option. As soon as they find a link that seems like it might lead to the goal, there is a very good chance that it will be immediately clicked. Optimizing is hard, and it takes a long time. Satisficing is more efficient.
Users follow their intuition. In most cases users muddle through instead of reading the information a designer has provided. According to Steve Krug, the basic reason for that is that users don’t care. “If we find something that works, we stick to it. It doesn’t matter to us if we understand how things work, as long as we can use them. If your audience is going to act like you’re designing billboard, then design great billboards.”Users want to have control. Users want to be able to control their browser and rely on the consistent data presentation throughout the site. E.g. they don’t want new windows popping up unexpectedly and they want to be able to get back with a “Back”-button to the site they’ve been before: therefore it’s a good practice to never open links in new browser windows.
