I have a forum, and I would like to add
rel=author to my pages. However, each page has multiple authors, and I'm not sure how I should implement
rel=author if I have multiple authors.
Does anyone have any advice?
Maybe someone is still seeing this question, so it could be useful to point out that Google no more supports Google Authorship
And it encourages the use of structured data.
So, no more need to add
rel=author for Google. It still exists as microformat and could be used by other applications.
You can still add where you are author through Google+ for social purposes.
But that doesn't mean Google no more recognizes author of a post. It analyzes structured data, bylines, citations, as always it did.
I used the instructions on the article How To Implement Rel=Author for creating my page. The only difference is that I had two
rel=author links instead of one. I then tested the page with Google's rich snippets testing tool, and the first author that was linked was displayed as if it were the only author. The second author was not displayed at all.
rel=author links is something that I think Google should recognize, as pages like forums and wikis usually have more than one author.
I couldn't find any
author-specific information, but the HTML specs do allow you to define more than one link with the same relationship, e.g.
<link rel="alternate" hreflang="de" href="//de.example.com/my/page.htm"> <link rel="alternate" hreflang="en-gb" href="//uk.example.com/my/page.htm"> <link rel="alternate" type="application/rss+xml" href="/my/page.rss"> <link rel="alternate" type="application/atom+xml" href="/my/page.xml"> <link rel="alternate" type="application/pdf" href="/my/page.pdf"> <link rel="alternate" type="application/pdf" media="print" href="/my/print-page.pdf"> <link rel="alternate" media="handheld" href="/my/mobile/page.htm">
I would assume that the same could be done with the
According to the HTML5 Working Draft:
The author keyword may be used with link, a, and area elements. This keyword creates a hyperlink.
For a and area elements, the author keyword indicates that the referenced document provides further information about the author of the nearest article element ancestor of the element defining the hyperlink, if there is one, or of the page as a whole, otherwise.
While the specification does not indicate a resolution for multiple authors specified at the HTML5 document level, the element level does provide support for multiple authors within a single HTML5 document (which should cover your forum's needs).
Testing a page on the testing tool i saw this:
Note: The testing tool currently only checks the first rel=author link listed on a webpage for a link to a Google+ profile [...]. It's possible that authorship may in fact be working for this page because of other rel=author links on the page. To verify that authorship is working on this page, please ensure the first profile listed on the site links to the appropriate Google+ profile.
