How many times have you searched for a keyword, found a site that looked promising, clicked on it, then waited and waited before finally clicking your back button when nothing came up? You don’t want your site to be that one! Pingdom Tools provide an excellent page load time tester for your web pages.
One aspect of SEO that you really need to pay attention to is your page load time, and this site will give it to you. It shows you exactly what URLs are being requested, when the requests come in, and when they get processed. I found that when I started optimising my sites for speed, their rank in Google soon increased.
If you use a lot of scripts on your site such as Javascript, or if you have many CSS files, it may be worth seeking to compress or combine them. Since this site shows you exactly what is being downloaded, you can use the results to help make any decision that may improve the speed of your site.
