I have three responsive ads within a page. Every ad unit loads adsbygoogle .jsbefore rendering.
<script async src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>
According to google, I understand I can load adsbygoogle.js once instead of three times. Ref: google's help document
My question is, can I place a single script tag before head close
</head>? Or should I include only within the body
