Does putting scripts on the bottom of a web page speed up page load?

by

It has a couple of advantages:

  • Rendering begins sooner. The browser cannot layout elements it hasn’t received yet. This avoids the “blank white screen” problem.

  • Defers connection limits. Usually your browser won’t try to make more than a couple of connections to the same server at a time. If you have a whole queue of scripts waiting to be downloaded from a slow server, it can really wreck the user experience as your page appears to grind to a halt.
