What is the rel=canonical tag?
This blog is hosted in a bunch of places:
https://jameshfisher.comhttp://jameshfisher.comhttps://jameshfisher-com.netlify.comhttp://jameshfisher-com.netlify.comhttps://jameshfisher.github.iohttp://jameshfisher.github.io
I prefer https://jameshfisher.com.
The others are old, or insecure, or implementation details.
To tell Google and everyone else which version you prefer, you can use the <meta rel="canonical" tag.
On every page you serve, you put a <link rel="canonical" href="..."/> element,
and this tells the client where the canonical location of that page is.
Like so for the page /foo/bar:
<!doctype html>
<html>
<head>
<link rel="canonical" href="https://jameshfisher.com/foo/bar"/>
</head>
<!-- ... -->
</html>
