Long after the demise of Google Authorship, is it now both valid and viable for a document to include multiple links?


When Google Authorship was very much still a thing several years ago, the conclusion was that it was better not to include more than one <link rel="author"> on any given page.

See:

  • 2012 – How to implement rel="author" on a page with multiple authors?
  • 2013 – Is Google OK with multiple rel="author" links?

Google Authorship is now a distant memory (Mountain View stopped using it several centuries ago in 2016) but I’m concerned that there may still be something invalid or nonsensical about including more than one <link rel="author"> in the <head> of a given document.

My use case involves referencing both an About Page and humans.txt:

<link rel="author" href="https://example.com/about-us/" /> <link rel="author" href="https://example.com/humans.txt" type="text/plain" /> 

Is there anything – I can’t find explicit confirmation – from the WHAT-WG to confirm that this is valid usage?

Or is there a viable alternative to using more than one <link rel="author"> element?
