Introducing Page Speed Online, with mobile support
By Andrew
Oates and Richard Rabbat, Page Speed TeamAt Google, we’re
striving to make the whole web fast. As part of that effort, we’re launching a new web-based
tool in Google Labs,
Page Speed
Online, which analyzes the performance of web pages and gives specific suggestions
for making them faster. Page Speed Online is available from any browser, at any time. This
allows website owners to get immediate access to Page Speed performance suggestions so they
can make their pages faster.
In addition, we’ve added a new feature: the
ability to get Page Speed suggestions customized for the mobile version of a page,
specifically smartphones. Due to the relatively limited CPU capabilities of mobile devices,
the high round-trip times of mobile networks, and rapid growth of mobile usage, understanding
and optimizing for mobile performance is even more critical than for the desktop, so Page
Speed Online now allows you to easily analyze and optimize your site for mobile performance.
The mobile recommendations are tuned for the unique characteristics of mobile devices, and
contain several best practices that go beyond the recommendations for desktop browsers, in
order to create a faster mobile experience. New mobile-targeted best practices include
eliminating
uncacheable landing page redirects and
reducing the
amount of JavaScript parsed during the page load, two common issues that slow down
mobile pages today.
Page Speed Online is powered by the same
Page
Speed SDK that powers the Chrome and Firefox extensions and
webpagetest.org.
Please
give
Page Speed Online a try. We’re
eager to hear your feedback on our
mailing list and find
out how you’re using it to optimize your site.
