The whole world is moving toward a faster and more energy efficient future. However, the amount of information being processed over the internet is growing exponentially.
In an effort to address these trends the W3C (World Wide Web consortium) as well as all of the world-leading search engines have recommended that websites take steps towards reducing their demand on both energy and bandwidth resources.
At the same time Google Caffeine, the latest update to the world’s most powerful algorithm, is now placing significant weight on the amount of time and processing power a website requires to load when creating their Search Engine Result Pages (SERPs).
Therefore, page loading time is now a powerful factor in Google’s search rankings. This alone should be enough to make all webmasters stand up and pay attention to this issue.
