Probably this is an obvious thing, but I am not sure about it. I created websites for my clients, and I am allowed to place back-links to my portfolio site. I placed a link in the footer, but I am interested to also place it into the html head. Is there any way to achieve this?
I have seen code lines like this:
<link rel="author" href="https://example.com">
I am sure that the author relation is not the proper value for that.
