How we do it

This is a non-invasive test that runs your URL through our cloud-based Site Optimizer service, without touching your code or network. Because the various tests we run on your site require time and hands-on input from our Performance Engineers, your page test results can take up to 3 business days. More on how we do it.

Not for everyone

While Site Optimizer will improve the speed of most sites, it will not work for sites that rely exclusively on Flash or Silverlight.
