Recently google introduced their new service "Google Page Speed Online" . after reading original post i am not getting how to use and how it will help to bloggers please help me?
It's very simple to use as you can see you just input your URL here: http://pagespeed.googlelabs.com/ This tool is to make sure your site is loading fast and it seems you can now test how fast your website loads on mobile devices. It's more useful to developers but if you page loads really slow, some have said, that Google doesn't like super slow websites. But really I think it's more to make sure that your users have a good experience on your website and to help developers make their sites load faster.
It is a Google analysing tool to test how fast a website loads. The website you entered will be given a score from 0 to 100 (example, 60/100), and along with that result, you will be given a suggestion on how to make that site load faster. This is really useful for website owners to reduce bounce rates (if these website owners thought their bounce rates caused the drop of their search engine ranking), and to improve their conversion rates.
I recently added the page load time feature on my blog. Here is my how to manual for tracking page load time via Google analytics
