Work with a mobile site designer
A substantial number of designers believe they can design and develop for any device. You'll hear arguments that it's unnecessary to develop an additional site for handhelds, and that it's better to come up with one site that displays nicely on desktops, laptops and handhelds. Sad to say, designers' beliefs are not always accurate. The limited capabilities of handhelds should not restrict what you do on other platforms. That's why, in many cases, it's more fruitful to have one designer creating your standard websites and another working off that design to optimize different coding for handhelds.
Test extensively before launching
You don't have to be a rocket scientist to understand that testing a site -- any site -- is very important. There are lots of testing services available, as mentioned on the next page. Point some of these tools at your mobile site and you'll quickly discover whether or not it meets all the applicable standards. It's also possible to use handheld emulators to make sure that pages load correctly on each of the devices you expect to be serving.
Plan to exploit localization
One of the most exciting aspects of the mobile web is its capability for localizing each user. Right now, Google Maps can pinpoint a user's location within about 2500 feet (the distance to the nearest cell tower), but GPS-enabled phones are far more accurate. Why not explore the best ways to leverage this technology? From a marketing perspective, localizing can be incredibly powerful because it allows you to compete for a person's business as they walk or drive down the street. The trick, of course, is to get people to opt in, so you have their permission to deliver localized offers to their phones.
