Seven tips for designing for older users

The discussion on web design for older site visitors often drift towards accessibility and get mixed up with looking at disabilities rather ability, but this should not forever be a given. Not every person over 65 years has eyesight so poor that they have to enlarge text size or change the contrast of text colours. Not each person over the retirement age has problems with motor control or significant short term memory loss. Here is a digested list of the most significant design tips based on research with users.

1. Make understandable what's clickable and what's not

You must clearly differentiate between paragraph, heading and link styles. Underlining link text within written text helps links to contrast with copy, but underlining links in the main navigation is not essential as each and every item should be obvious. Also, don't employ underlining to recognize headings. Buttons must also be made as huge and prominent as possible so they become a clear call to action. 3-Dimensional effects for buttons can help to make them stand out. Also, create links and buttons easy to aim and hit by rising their clickable area.

2. Utilize radio buttons rather than dropdown menus

A dropdown menu can be fiddly and time intense for site visitors, and can result in people selecting the wrong item by accident. If you have less than ten items in a dropdown menu use radio buttons if possible. These have the benefit of showing the number of options at a glance without having to click. However, you should keep dropdown menus where they are recognized conventions.

3. Wait in one window

If possible, always stay in single window. If you like to provide helpful tips or explanations, consider implement it in a way that the explanation appear on the same page. If you require including a pop-up or re-directing to a new window, then inform the users by telling them. A good example of showing helpful tips on the same page is twitter's sign-up page. Here the details comes up when users click into the field “Full name”.

4. Apply the shallowest possible information hierarchy

Ensure that you completely understand your users' goals and provide them with the shortest paths to completing their task. Pull out significant and frequently visited topics and display them on the homepage. You should also maintain consistent labeling of links and page names and permit site visitors to get to the content within 2-5 clicks. The path must be kept as clear as possible of distracters such as advertising, though you can display some after the task has been finished successfully. Provide about 3 useful cross-reference links that are related to the current task goal, but not many more in order to avoid distraction. Overall, try to minimize the options on screen to be as succinct as possible.

5. Include a site map and link to it from each page

A site map gives users a good overall picture of how the sites is organized and clearly define all the resources the website has to offer. The link to the site map can generally be found near the top or the bottom of the page and regularly placed near the link to 'contact us'. Internet savvy senior surfers are aware of site maps and make use of them to gain an outline of the site. They will also likely click on a sitemap link when they get lost on the site or if they cannot get what they want while browsing. 

6. Maintain your language simple  
          
Avoid technical language at all cost. However, if you employ newer functionality such as tagging for example, don not try to rename it, but provide an easy to know explanation for it. Include information in plain English where essential and always try to reduce the number of words displayed on the page. Use simple and small sentence and include bullet points where possible. For links on the homepage or landing pages include a short description to tell site visitors what to guess when following the link.

7. Show trustworthy

Senior surfers tend to be more cautious when browsing and can get puzzled when something unexpected occur such as a new window opening or an application installing. Firstly, clearly state the use of your site on the homepage. Also, offer a brief explanation with content links, so users know what to expect when following them. Explain in 'large print' how personal information will be handle before asking user to enter it. Make use of the well-known padlock icon to specify a secure part of the site. Show terms such as 'secure', 'safe' and 'confidential' in bold. Offer a content section on security when your site recommends financial services.
