And according to this thread on StackOverflow it's not absolutely necessary to have the GA tracking script in the header. It only increases the change of having the beacon trigger before the user leaves the pages. And that time frame is a really short one, especially for a small landing page.

Thank you, Linus! The GA code may work in the body tag, but the favicon code does not work at all, unfortunately. The code I've been using only worked in the head tag.
