The mobile web trouble users

A usability study by Jakob Nielsen shows that people using websites on their mobile phones suffer from old-time usability issues, such as slow download time, bloated pages, and difficulties using the browsers.

To improve usability of mobile web browsing, Jakob Nielsen recommends that big and rich sites provide different websites tailored to each type of mobile device on the market. Sites that need to serve mobile devices but can't afford building many different versions should supplement the main site with a single scaled-back mobile-optimized design, recognizing that it will serve high-end phones poorly.

The study reveals that people have problems with all kinds of mobile devices. Even the iPhone isn't perfect, though it is, as Jakob says, "the first mobile Internet device worth criticizing."

Speed matters

At a conference, Greg Linden heard Marissa Mayer from Google speak about how a response time delay of half a second at Google Search resulted in a traffic and revenue drop by 20%. Also, when they rolled out a lighter version of Google Maps, there was a substantial boost in traffic.

Greg Linden has experienced the same thing at Amazon.com. In a test they found that even very small delays would result in substantial and costly drops in revenue.

Apparently, speed - in terms of milliseconds - matters.

Download time doesn't impact on a site's usability

UIE keeps podcasting interesting interviews with Jared Spool. In this episode of the Usability Tools Podcast, Jared talks about a study that showed that a site's download time doesn't seem to impact on a site's usability. Instead, sites that are easy to use, fun and professional are perceived as being fast.

Apparently, people perceive time to take longer when they are in pain.

Server side usability - How to make web servers behave

Most usability professionals don't have a driver's licence to servers and are not aware of the step that can be taken to make them behave in a user-friendly way. The GUUUI Q4 2004 issue takes a look at how to avoid that server technology becomes an obstacle to usability.

The article suggests that we should:

- Make the "www" prefix optional
- Support "www" prefix typos
- Support domain name typos and spelling errors
- Support erroneous country codes
- Use tidy URLs
- Don't leave users in a dead end when a page cannot be found
- Alert users when a server error occurs
- Have a "We are updating" page ready

"Until user agents allow users to turn off spawned windows, do not cause pop-ups or other windows to appear

Speed Up Your Site

Jennifer Alvin from Digital Web Magazine reviews Andrew King's book Speed Up Your Site: Web Site Optimization:

"Andrew King offers a variety of ways to trim the fat in common design elements, as well as tips for increasing server performance. No other book I've seen covers so many types of optimization in one place with such a thorough investigation of why the tricks work. The extensive technical explanations alone are worth the list price, and each is backed up with a step-by-step approach to making your site a speedy champion."

User-friendly URLs

Often URLs are hard to type, remember and preserve, because they are littered with punctuation and identifiers that are irrelevant to us. Thomas A. Powell and Joe Lima show us how to design well-formed and user-friendly URLs.

Some highlights:
- Keep them short and sweet
- Use lower case
- Do not expose technology via directory names (e.g. /cgi-bin/)
- Avoid punctuation in file names (e.g. product_spec.html)
- Plan for host name typos (e.g. wwww.guuui.com or www.guui.com)
- Allow omission of the www prefix (e.g. guuui.com)
- Add guessable entry point URLs (e.g. www.guuui.com/about/)
- Remove or rewrite query strings (e.g. posting.asp?postingID=313 to posting313.asp)

iHotelier: Demonstrating the Potential of Flash for Web App Design

From a design perspective, creating a successful hotel reservation system can be one of the more complex user experiences.

Christine Perfetti (UIE) wrote about a Flash-based hotel reservation system that has recently caught attention: iHotelier.

It demonstrates how Flash-based applications can deliver users positive experiences, where HTML, DHTML and even sophisticated JavaScripting leave off.
