Building mobile websites: Critical issues that every developer should know

Some time ago we published a blog post with tips on developing a mobile web. That blog post generated new inquiries from readers, which were answered by the Tangelo’s developers. They are experienced professionals in the field who daily confront difficulties, generate solutions and constantly refine their work.

Based on these consultations we have produced this blog post, delving in some critical points that Tangelo’s developers have found necessary to excel in their projects for world-class companies.

We hope you enjoy it and continue asking us questions, because we are here to help you be better.


Limitations on the transfer speed, in 3G networks

Something very important when developing a website is to reduce the loading time to a minimum. Each second delay to download a web site is equivalent to 10% loss of new users. While this is important for every development, in the case of mobile websites, this is an even more sensitive issue because people do not always use a wifi network to access your website.

In addition, the waiting time to download “heavy resources”, such as images or videos, means normally an extra cost for users.

Limitations because of the screen size and navigation on mobile devices

Screens of mobile devices are small, so surfing the Internet can be difficult in certain devices, such as those which use the keyboard to surf the Net. The content of the website must be concrete. Thus, the user will do only a few keyboard strokes to get the desired information.

Variety of devices

On the market there is a large variety of mobile devices.

The greater the support desired by the developer (for differents devices), the greater must be the simplicity of the site developed. For example, if a site has flash content, it will not be 100% accessible from Apple devices. The complexity of the Javascript code is also a limitation for some devices, which will can not correctly render this code.
Juan Cruz Ghigliani, one of our developers, acknowledges that the Yahoo and Google sites (search engines and e-mail)  are very well adapted to the limitations of browsing in a mobile device: “Google’s site is very simple and fast, even this is 2 or 3 times faster than Yahoo, said Juan Cruz.
