Introducing Page Speed Online, with mobile support

Webmaster level: intermediate



At 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 how you’re using it to optimize your site.

Flash support in Instant Previews

Webmaster level: All

With Instant Previews, users can see a snapshot of a search result before clicking on it. We’ve made a number of improvements to the feature since its introduction last November, and if you own a site, one of the most relevant changes for you is that Instant Previews now supports Flash.

An Instant Preview with rich content rendered

In most cases, when the preview for a page is generated through our regular crawl, we will now render a snapshot of any Flash components on the page. This will replace the "puzzle piece" icon that previously appeared to indicate Flash components, and should improve the accuracy of the previews.

However, for pages that are fetched on demand by the "Google Web Preview" user-agent, we will generate a preview without Flash in order to minimize latency. In these cases the preview will appear as if the page were visited by someone using a browser without Flash enabled, and "Install Flash" messages may appear in the preview, depending on how your website handles users without Flash.

To improve your previews for these on-demand renders, here are some guidelines for using Flash on your site:

• Make sure that your site has a reasonable, seamless experience for visitors without Flash. This may involve creating HTML-only equivalents for your Flash-based content that will automatically be shown to visitors who can't view Flash. Providing a good experience for this case will improve your preview and make your visitors happier.


• If Flash components are rendering but appear as loading screens instead of actual content, try reducing the loading time for the component. This makes it more likely we'll render it properly.


• If you have Flash videos on your site, consider submitting a Video Sitemap which helps us to generate thumbnails for your videos in Instant Previews.


• If most of the page is rendering properly but you still see puzzle pieces appearing for some smaller components, these may be fixed in future crawls of your page.

If you have additional questions, please feel free to post them in our Webmaster Help Forum.

As always, we'll keep you updated as we continue to make improvements to Instant Previews.
