get google fonts onto your server with just one <link>
instead of
<link href="https://fonts.googleapis.com/css?family=Nunito+Sans|Roboto" rel="stylesheet">
use
<link href="goofi.php?family=Nunito+Sans|Roboto" rel="stylesheet">
and the script will get the fonts & css and then save it onto your server. After that, no more queries will be send to google's servers anymore ;-)
