Fine Tuning Mobile: A study of how large Webcos do it

Last week, dotMobi CTO Ronan Cremin published a very interesting study on Mobiforge looking at how some of the biggest companies on the web fine tune their mobile experience across different devices. He modeled a range of different devices with differing device capabilities and then calculated a ratio of the heaviest web experience  companies served, compared to the the lightest experience they served.

The results shine a seriously interesting light on something that differentiates the big players from the rest of the pack: they take performance, speed and optimization of their web content very seriously. The top 3 sites on the web - Google, Facebook and YouTube, all serve a wide range of experiences (and page weights) to their customers, depending on the device they are using.

The 'dynamic range' -- a measure of how big of a difference there is between the experiences they are serving -- are all very high showing that they are serving radically different versions of their content depending on what the requesting device is . Companies who serve the same experience to all devices have a dynamic range of just 1. The full study results, methodology and data are all published here.
