document: How Fast Is Your Site ? Measure It With Google &#8217; s Page Speed Online Editors note : The following guest post is written by Josh Fraser . Josh is the co-founder of a new startup called Torbit which automatically optimizes websites for speed . Yesterday Google announced Page Speed Online , which provides a quick and easy way to accurately measure the speed of your website directly from the web . Previously available only as a browser add-on , Google Labs launch allows you to analyze your site from anywhere and receive instant feedback on making it faster . Chances are , your website could perform better - all of ours could . There are a lot of tools online that only measure server response time , giving an inaccurate picture of your site 's speed . For example , blazing fast servers might return your HTML in a fraction of a second , but visitors to your site will still be waiting for images to download or javascript to be executed . In contrast , Page Speed Online uses a webkit-based renderer to time all components of your site for a more complete picture of its performance . Page Speed Online is simple to use . Just enter a URL and get instant suggestions for performance improvements on your site . Page Speed Online gives you a score out of 100 and breaks down suggestions by their priority . Google caches the results , making it faster to use than comparative tools like WebPageTest which offers more features . With Page Speed Online you can also get mobile-specific recommendations . For instance , since mobile device CPUs are less powerful than desktop CPUs , suggestions that reduce CPU consumption will be featured more prominently . Performance matters . We all know that . Everyone can relate to the frustration of waiting on a site that takes forever to load . Website owners in particular should care about performance . The correlation between the speed of your website and revenue has been shown over and over again . Improving your site 's performance is the easiest way to increase pageviews , conversions and sales . For example , Yahoo found that a 400ms improvement to the speed of their site increased their pageviews by 9 % . Firefox shaved 2.2 seconds off their average page load time and increased download conversions by 15.4 % . Shopzilla reduced their loading time from 7 seconds to 2 and increased their pageviews by 25 % and revenue by 7-12 % . Google has been a long-time champion of making the internet faster . Not only did it rise to prominence by being the fastest search engine , but it also encourages other sites to be fast by using site speed in its web search ranking . Google has also released a slew of tools to help website owners measure and improve the performance of their sites . Google released Page Speed plugins for Firefox and Chrome and include performance data in its webmaster tools . Just yesterday , Steve Souders announced HTTPArchive which keeps an archive of how top websites are built and tracks their performance ranking over time . The data is being recorded using real browsers so the archive is an accurate representation of the experience of actual visitors . Performance is obviously a priority for Google and it 's something we all value . Venture capitalist Fred Wilson even calls speed '' `` the # 1 feature for startups '' '' . Page Speed Online is an important step for the web because it 's lowering the bar for people who want to do performance analysis on their sites . You no longer have to download desktop software , install a plugin or even have a copy of the browser that you 're testing -- all you need is any browser . Google employee and performance guru , Steve Souders told me a story from a party he attended where a startup CTO was asking him for site improvement suggestions : I did n't have my laptop handy and was about to give up , but then I remembered Page Speed Online . From my mobile phone I was able to run his site through Page Speed Online and give him specific performance fixes . On top of that were the suggestions for mobile . Page Speed Online provides performance analysis for any website for desktop and mobile from any web client . I also talked with the tech lead for Page Speed Online , Bryan McQuade and asked him what was next for the service . He says : Going forward we 're planning to add even more mobile-targeted analysis to the open-source Page Speed SDK , which powers Page Speed Online , our Page Speed browser extensions , and is used by WebPagetest and other sites . Of course , Page Speed Online will only tell you that your site is slow ; it wo n't fix it for you -LRB- although there is an Apache module that helps -RRB- . Our company , Torbit , and others such as Disrupt runner-up CloudFlare and Blaze.io , are working to automate all these best-practises to make websites fast . Torbit is still in private BETA , but you can sign up now to get in before our public launch .
