[Gd] PageSpeed Service makes mobile sites faster

Google Developers Blog: PageSpeed Service makes mobile sites faster

PageSpeed Service (PSS) is an online service to speed up the rendering of your web pages by rewriting and serving them through Google. While PSS’s optimization techniques benefit most platforms and browsers, today I’d like to focus on some of the PSS rewriters that are especially effective on mobile web pages. PageSpeed Service optimizes the web pages in such a way that users can start viewing and interacting with your pages as soon as possible.



Prioritize Critical CSS: To avoid page reflows, modern browsers do not render pages until the CSS is downloaded and parsed. These CSS files are often tens of KBs because they include all the styles needed for the entire site. These blocking requests are especially bad on mobile devices, where network round trip times are high. The Prioritize Critical CSS rewriter speeds up rendering by identifying the minimal CSS required to render that page and including it in the HTML file. This not only saves an extra round trip to download additional files but also reduces the CPU consumed by the browser. Finally, a reference to the original CSS file is included at the end of the page to lazy-load the non-critical CSS.

Defer JavaScript: The HTML specification requires the browser to stop, download, and execute each synchronous JavaScript file before proceeding to build and render the page - this requirement can significantly slow down rendering. PSS circumvents this behavior by rewriting the HTML to defer execution of all JavaScript until after the page is first rendered. This benefits pages that are mostly rendered via HTML markup rather than JavaScript.

Optimize Images: Mobile screens are almost always smaller than their desktop counterparts. Large, high quality images translate to excessive bytes on the wire, slowing down page loads. PSS can resize images on the server to fit required dimensions and re-compress them to the optimal format, without perceptible visual loss. For very large images above the fold, PSS can also inline a low quality preview image for initial rendering. Once the rest of the page content loads, it is replaced by the original image, creating a seamless experience. Furthermore, images below the fold can be lazy-loaded, which prevents them from competing with the rest of the page load.

PageSpeed Service includes several rewriters that speed up the rendering of web pages. Using PageSpeed Service, the mobile pages of TopNewsToday and Net1News are now 61% faster and 68% faster respectively. Alex Tsvetanov of TopNews Today says, “With Google PageSpeed Service, we increased our unique visitors and total pageviews by 100%, while reducing our bounce rate by 30%”. Massimo Romanello, CEO of Net1News says, "Thanks to Google PageSpeed Service, we have been able to reach 200,000 unique daily visitors with the same existing infrastructure and have made our site one of the quickest in the news sector".

PageSpeed takes just a few minutes to set up and requires no code changes on your site. Check out how much PageSpeed can speed up your site. I encourage you to try out these features by signing up for PageSpeed Service and letting us know what you think at page-speed-service-discuss@googlegroups.com.


Ram Ramani is an Engineering Manager on the Make the Web Faster Team in Mountain View. He is a believer in "Faster is better".

[Gd] Update on Tablet App Guidelines and Screenshots

Android Developers Blog: Update on Tablet App Guidelines and Screenshots

Posted by Ellie Powers, Google Play team



More and more, developers are investing in a full tablet experience for their apps and seeing those investments pay off big. Starting today, it’s even easier to show off those tablet apps to users and to understand what it takes to make a great tablet app.



Many of you have already made optimizations to your apps to make them more beautiful and useful on tablets, and we’re giving you a way to showcase your application’s specialized tablet layouts. You’re now able to upload screenshots of your app running on 7” and 10” tablets to the Google Play Developer Console, and those screenshots are shown preferentially in Google Play to users on those devices.



In October, we published the tablet app quality checklist, which shares best practices for creating tablet applications that users will love. We've updated this checklist with additional tips and guidelines, as well as more details on specific technical checks you should perform to ensure your app is correctly optimized for tablets. Soon, we’ll start surfacing tips based on our tablet app quality guidelines directly in the Google Play Developer Console, and we’ll use these guidelines to help users better discover tablet apps in Google Play.



So upload your tablet screenshots and confirm your app follows the quality guidelines today.

Google Developers Blog: Fridaygram: fiber marches on, your brain on music, Earth from orbit

Just about two years ago, we said that Kansas City would be the first place to get very high speed Internet access from the Google Fiber project. This week we announced that Austin, Texas will be the next location for Google Fiber. Like Kansas City, customers in Austin will be able to get gigabit Internet and Google Fiber TV service. Many schools, hospitals, and other public buildings in Austin will get gigabit Internet at no charge.



If you live in Austin or Kansas City, and you want to find out more, take a look at the Google Fiber website. Or maybe you’ll want to plan to move to one of those cities.

Speaking of moving, the next time you’re moved by music, you might be interested to know what’s going on in your brain. Recent research shows that when people like a new song, the nucleus accumbens becomes active, while other parts of the brain work on pattern-matching and emotional connections. The more complex the activity among these various brain regions, the more the brain's owner likes a song, according to the research. Scientists are hoping to use this work to learn more about how we process all kinds of sounds, not just cool new tunes.

Finally, take some time this weekend to watch this amazing NASA video of Earth from orbit. It’s part of NASA’s Earth month, which includes a bunch of other images of our favorite planet that are also fun to look at. It’s sure to light up your brain.


With all its interplanetary travel, it’s nice of NASA to have a month just for us earthlings. And here on the blog, we’re happy to have Fridaygrams, which allow us to depart temporarily from developer world and just feature some random, nerdy, science-y stuff instead.
