I can't take credit for this, but it's something I refer to often in my bookmarks. In this StackOverflow discussion, someone asked what the best order was for elements in the <head> tag of an HTML page.
The order of most elements in the <head> doesn't really matter. It's a matter of preference, and they should be ordered any way you like.
Matej Janovčík provided this sample <head> tag with a tidy order as an example. I've made some minor adjustments and I use this snippet a lot, so I continue to update it as things change. You can add or remove whatever you like, or expand on this if you need more metadata:
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title></title>
