Hello friends, As we know that Google is the mostly used search engine and it having so many algorithms for appearing sites in Google Search. There are so many crieteria exists in Google Algorithm to get site good ranking and currently Google pulished on their blog that today they are including a new signal in our search ranking algorithms: site speed. Site speed reflects how quickly a website responds to web requests.

Google has added one site performance feature in Google webmaster tool before, So you can check that your site is loading fast or taking so much time to load. According to Google “Speeding up websites is important — not just to site owners, but to all Internet users. Faster sites create happy users and we’ve seen in our internal studies that when a site responds slowly, visitors spend less time there. But faster sites don’t just improve user experience; recent data shows that improving site speed also reduces operating costs. Like us, our users place a lot of value in speed — that’s why we’ve decided to take site speed into account in our search rankings. We use a variety of sources to determine the speed of a site relative to other sites.”

Also Google suggests some free tools that you can use to evaluate the speed of your site:

• Page Speed, an open source Firefox/Firebug add-on that evaluates the performance of web pages and gives suggestions for improvement.
• YSlow, a free tool from Yahoo! that suggests ways to improve website speed.
• WebPagetest shows a waterfall view of your pages’ load performance plus an optimization checklist.
• In Webmaster Tools, Labs > Site Performance shows the speed of your website as experienced by users around the world as in the chart below. We’ve also blogged about site performance.
