Google page speed insights keeps saying that I need to preload key requests and gives the following information on how to do that here:
Consider using <link rel=preload>
to prioritize fetching resources that are currently requested later in page load.
Problem is, I have no idea how to add this to my header and would like to know if there is a tutorial on how do do this? It is costing me 2.07 s per PSI report and I have been losing mobile traffic due to a low PSI score.
Thank you
