Nearly a year ago, we launched
Page
Speed for Chrome, which has enabled Chrome users to get Page Speed performance
suggestions to make their desktop sites faster. Today, we are releasing an update to Page
Speed for Chrome that supports mobile Page Speed analysis via Chrome for Android. With Page
Speed for Chrome and Chrome for Android, you can perform Page Speed analysis on the mobile
version of your web pages, as they are loaded in the
Chrome
for Android mobile browser.
Many web sites serve mobile-specific versions of their pages. Often, the mobile pages have
very different Page Speed scores and Page Speed reports from their desktop counterparts. Page
Speed on Chrome for Android makes it easy to analyze both the desktop and mobile versions of
your web pages, so you can be sure that your pages load faster for the users of both your
desktop and mobile sites.
When analyzing the mobile version of pages, Page Speed for Chrome tunes its analysis to
reflect the unique performance characteristics of mobile devices and networks, suggesting the
optimizations that will have the biggest impact on reducing load times for your mobile users.
Using the powerful Chrome Developer Tools Extension APIs, Page Speed for Chrome can identify
renderer performance optimizations that are especially relevant on mobile, such as removing
unnecessary reflows and finding long-running scripts that slow down your pages. Page Speed for
Chrome will also automatically minify and optimize your HTML, JavaScript, CSS, and image files
and make them available for you to download, so you can easily deploy them on your web
server.
To get started using Page Speed on Chrome for Android:
- Follow the instructions to install the Page Speed
for Chrome extension on your desktop Chrome browser.
- Enable
remote debugging in Chrome running on your Android device.
- Navigate to the remote Chrome Developer Tools page in your desktop browser
(localhost:9222) .
- Select one of the Chrome tabs running on your Android device.
In addition to the full Chrome Developer Tools, you will see Page Speed in the
Developer Tools panel. Click the Page Speed icon to switch to the Page Speed tab, then click
Run Page Speed to generate mobile Page Speed suggestions for the web page
that’s loaded on your Android device.
We hope you’ll give Page Speed for Chrome on Android a try. Please send us feedback via our
