Mobile devices have limited memory, which means that large files requiring lots of memory download slowly. The file size of a web page is determined by the number of words, the number and size of pictures and videos, and other design elements on the web page. Use of flash technology is notorious for slowing download times. Pages that are cluttered or poorly designed take longer to download. All of these factors can be modified to make a site download quickly.
Proactively Design to Speed-Up Downloads
Reducing the resolution of pictures to 72 dpi and compressing videos can go a long way towards reducing file sizes. According to Reworkengine.com, the following steps will also help to optimize sites for mobile devices, speedup download times, and give sites a more favorable appearance on mobile devices:
Make optimal use of white space.
Keep sentences and paragraphs sweet and brief.
Keep the number of pages on your site to a minimum.
Keep the number of text entry boxes to a minimum.
Use Emulators to See How Sites Look
iPad Peek is a free web based service that shows how sites look on the iPad. WordPress and Drupal mobile plug-ins are also available to help optimize blogs and websites for mobile use.
