Pass HTML Validation, Collect 1M$

Filed under:

I was recently pointed to another example of important bandwidth saving due to using proper XHTML and CSS. Nothing very new, but the figure of 1M$ is pretty interesting.

The standout paper was by Brett Jackson from Fairfax Digital, detailing how they moved to validated XHTML with CSS. They deliver 164,000,000 page impressions per month for the major dailies The Sydney Morning Herald and The Age. They do day parting: different kinds of stories are emphasized at different times of day. Later in the day people want gossip, analysis and entertainment but in the morning they want breaking news and weather.

This very much relates to the namespaceDocument issue the TAG has in its queue

Valid Markup saves battery life

Filed under:

T-Mobile in their position paper to the Mobile Web Initiative Workshop note that

The very fact that advanced browsers allow greater mark-up flexibility unfortunately reduced the amount of care taken to assure standards compliance and led to a broader use of sloppy mark-up – but unlike to desktop browsing this has quite severe consequences for users of devices with radically limited resources: rendering non-deterministic mark-up has a very real impact on CPU, memory and battery life, and also mostly leads to unwanted and costly data overhead on the radio transmission – for customers and operators all alike.
