user awareness on the part of the site designer.
Design should first aim for optimum performance on mobile devices, with the desktop experience coming secondary.
In the 21st century, this is a risk worth taking; mobile users are far more fickle with greatly reduced attention spans.
It only takes one notification to take a viewer off your webpage and into a proprietary app that is purposely designed to keep users logged in.
The better your site experience on the phone, the longer it can resist the onslaughts of notifications and retain viewers on the site.
HTML5 can look and perform extremely sexy on a powerful device. And only on a powerful device.
For old devices running on old operating systems or browsers, these features are mostly emulated to be able to be properly rendered.
This consuming lot of processing power and memory space, something that is already at a premium in these not so high-end devices.
This results in at best an unusable webpage and at worst, a crashed device that needs to be rebooted.
So it would be best to refrain from the cutting edge technologies and instead focus on the established technologies that are supported by devices that are at least two to three generations old.
Analytic can be woefully misleading in that they only record data that has been successfully served to the clients.
If your data does not show any devices older than 2013, it does not necessarily mean that those old devices are not available in the market or that people are not using them anymore.
Instead, it may signify that your website is not being served on those devices at all, resulting in a proportion of traffic lost to bad design.
