CHECK WEBSITE SPEED

Page load time (speed) is a factor currently in the AdWords quality score. But soon it may be coming to Google's organic ranking algorithm. If you have a really slow site, it may impact how high you rank in Google.

Page Speed is an open-source Firefox/Firebug Add-on. Webmasters and web developers can use Page Speed to evaluate the performance of their web pages and to get suggestions on how to improve them http://code.google.com/speed/page-speed/

Google wants the web to be a faster place and Google does control much of what people see on the web. So Google can influence that people find faster web pages, over slower ones.
