A usable site will be able to:
- Help users achieve a goal, usually to find something, like information, or acquire something, such as a book.
- Make it simple or easy for them to achieve that goal.
- Make it feasible to achieve the goal quickly.
- Make achieving of that goal a pleasant experience.
A site will be generally usable if it contains the following:
- The content is effective and relevant
- The content is easy to find
- The content can be found as fast as possible
- The page is pleasing to look at and clearly designed
Good content is critical
A site with an effective and good content, irrespective of its subject, is one that makes products to be available or provide information that is useful or beneficial to users. A good or effective usable site will make clear what information or content is on ground and at what price AND what is not on ground or not available. An effective usable site should state clearly all subscription packages offered.
Good navigation, precise location indicators, clear link text , secondary navigation and a well organized structure add to making information easy to find for a wide range of categories of users.
It may be necessary to include explanations of things you consider self explanatory, having in mind that many users are inexperienced, for instance, an inexperience user may need an over-view or explanation of how to make use of a drop down menu to go with. For people to use your website, make sure you make it as easy as possible.
Quick Access to Information
This is the main purpose or aim of web users. It can be divided into two important aspects:
Speed of Page Loading
This entails, in particular, attention to images or pictures to ensure they are well optimized and does not delay load time. It may also mean breaking up long articles and ensuring that the most important content is at the top of the page, where it will load first.
Speed of Access to Content
No important content should be more than 3 clicks from the home page – this is where the 3-click rule comes in. some standards says that it should be more than two clicks.
One useful way to speed access to content is to look into each type of user, select the content that they may likely be interested in and create links from the home page to one piece of content for each of the group. This will help in order to get them quickly to the suitable part of the site.
Cleanly Designed Pages
Cleanly designed pages are pleasant to look at and simple to read. It is almost not possible to make a site with an image that is shown as a tiled background usable- the whole thing is too confusing and distracting. To create clean pages does not require great design skills, it just require thoughts and adherence to the principle, when it comes to design, something that is less is usually more.
There should be clear download instructions provided. most paid membership websites does not really put more efforts on selling goods but are limited to online access and information download. Your website should also have a rough calculation of time of download for a user having a 56k modern, DSL; and so on and also state the size of the life in kilobytes.
Studies may be essential, while for large commercial sites investment in full-scale usability is very important. Some few small sites can provide such luxuries.
Nevertheless, identifying problems with usability for your site need not to be convoluted than asking a few (sincere) friends to act as guinea pigs on your site, if possible, observe them quietly as they do this. Watching users try to find information at your site can be both conveying and quite surprising.
Reminisce that if at any stage you feel the strong desire or urge to intervene and explain, then you have come across a usability problem.
List of the Most Common Usability Problem
- The site does not state its intention clearly
- There are some flashy elements that slow down loading, for example java applets, huge images and banner ads.
- The site request specific software to be used. Have you ever tried downloading a piece of software just to see a site or have you actually changed browsers.
- Inadequate navigation, too small navigation, too much navigation and, not uncommonly, no navigation at all.
- Faulty design leading to poor readability
- Distress due to ugly design or inconsistent design. Almost always because a designer overestimated their skills.
- Irrelevance of content – for instance the business site that includes biographies and photos of each of the board members. Happy egos on the board: the visitors will be bored.
- Complex or excessive originality of design, which ask of users to learn how it works in order to use it.
- Inaccessible – because the site cannot be used by browsers for people with disabilities.
