Approaches which, used properly, can lead to more sophisticated design decisions and simplify the process of perceiving presented information
Usability  and the  utility , not the visual design, determine the success or failure of a web-site.  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.
In order to use the principles properly we first need to understand how users interact with web-sites, how they think and what are the basic patterns of users’ behavior. How do users think?
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.
Users appreciate quality and credibility. If a page provides users with high-quality content, they are willing to compromise the content with advertisements and the design of the site.
Users don’t read, they scan. Analyzing a web-page, users search for some fixed points or anchors which would guide them through the content of the page.
Web users are impatient and insist on instant gratification. Very simple principle: If a web-site isn’t able to meet users’ expectations, then designer failed to get his job done properly and the company loses money.
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 web-page 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.
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…”
Users want to have control. Users want to be able to control their browser and rely on the consistent data presentation throughout the site.
1. Don’t make users think
Let’s take a look at an example.  Beyondis.co.uk   claims to be “beyond channels, beyond products, beyond distribution”. What does it mean?
ExpressionEngine  uses the very same structure like Beyondis, but avoids unnecessary question marks.
2. Don’t squander users’ patience
Stikkit  is a perfect example for a user-friendly service which requires almost nothing from the visitor which is unobtrusive and comforting.
3. Manage to focus users’ attention
Humanized.com  perfectly uses the principle of focus. The only element which is directly visible to the users is the word “free” which works attractive and appealing, but still calm and purely informative.
Dibusoft.com  combines visual appeal with clear site structure. The site has 9 main navigation options which are visible at the first glance.
5. Make use of effective writing
Eleven2.com  gets directly to the point. No cute words, no exaggerated statements. Instead a price: just what visitors are looking for.
6. Strive for simplicity
Finch  clearly presents the information about the site and gives visitors a choice of options without overcrowding them with unnecessary content.
7. Don’t be afraid of the white space
White space is good.  Cameron.io  uses white space as a primary design element. The result is a well-scannable layout which gives the content a dominating position it deserves.
8. Communicate effectively with a “visible language”
In his papers on effective visual communication, Aaron Marcus states  three fundamental principles  involved in the use of the so-called “visible language” — the content users see on a screen.  ORGANIZE ECONOMIZE COMMUNICATE
Organize:  provide the user with a clear and consistent conceptual structure.  Consistency , screen layout, relationships and navigability are important concepts of organization. The same conventions and rules should be applied to all elements.
Economize:  do the most with the least amount of cues and visual elements. Four major points to be considered:  Simplicity Clarity Distinctiveness Emphasis.
Communicate:  match the presentation to the capabilities of the user. The user interface must keep in  balance legibility, readability, typography, symbolism, multiple views, and color or texture  in order to communicate successfully. Use max. 3 typefaces in a maximum of 3 point sizes — a maximum of 18 words or 50-80 characters per line of text.
9. Conventions are our friends
With conventions you can gain users’ confidence, trust, reliability and prove your credibility. Follow users’ expectations — understand what they’re expecting from a site navigation, text structure, search placement etc. (see Nielsen’s  Usability  Alertbox  for more information)
10. Test early, test often
Some important points to keep in mind: according to Steve Krug, testing one user is 100% better than testing none and testing one user early in the project is better than testing 50 near the end  testing is an iterative process.  usability tests always produce useful results.  according to Weinberg’s law, a developer is unsuited to test his or her code. This holds for designers as well.  Bottom line: if you want a great site, you’ve got to test.
