Simple google authorship and avatar plugin

Provides an easy to use interface for site authors to claim google authorship, and use their google profile picture as an avatar.

Main features

  • Users authenticate their google accounts via Oauth protocol and get the required info using the appropriate google API calls.
  • Inserts a <link href=”User’s G+ profile URL” rel=”author”> into the head part of the HTML for any content type created by the user. The existence of the link lets google know that the user is the author of the content and display his picture next to search results.
  • Use the users google profile picture as avatar image in comments and admin

Back story

User authentication via the Oauth protocol eliminates the need for the user to find out what is his google profile URL, and copy&paste it without mistake. An already registered application is used as a proxy for authentication and using the API, and no extra work is involved. For the user, authentication, and gathering the required info, is just one click away.

Once authenticated, anyone who can edit the user’s profile can set it to show or hide authorship and use google picture as avatar.

Network considerations

The plugin will work for any sub site in the network for which it was activated (or if the plugin is network activated).

Any change the user will make to its profile will impact all the sites in the netwrok in which the user had posted or commented.


User still needs to aadd the site to his G+ profile “contributor to”  or “profile” links in order for the google authorship to work.
Only the user can authenticate himself, therefor an admin can not set authorship or avatar instead of the user.
In network usage, sub sites admins can’t edit other users profile therefor they will not have any control and only the super admin will be able to change the settings.

How many authors are in a blog page? many!

In my opinion , in the discussion around google authorship there is too much emphasize about main content writer authorship, but  almost no mention that the content indexed by google is made up also from comments and the have authors as well.

This is even more obvious in forums and Q&A sites. Who is the author of a page on stackexchange, the one who asked the question or the ones who supplied the answer. It is even more complex in wiki sites.

It feels like while people were rushing to see faces on the search results hoping for some SEO juice, they haven’t tried to reed the text of the spec

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.

And article elements are not necessarily the whole content of the page (emphasize mine)

The article element represents a self-contained composition in a document, page, application, or site and that is, in principle, independently distributable or reusable, e.g. in syndication. This could be a forum post, a magazine or newspaper article, a blog entry, a user-submitted comment, an interactive widget or gadget, or any other independent item of content.

But google right now will not let me claim authorship over my comments :( . The way you need to configure your profile to claim authorship is just not user friendly enough to do it for every site I comment on, just too much work.

Why would I as a site owner wish to let commenter claim authorship on comments? because if I have quality commentators people might come to my site because they follow them.

google fails to understand that authorship is a markup territory and not display territory

A quote from the webmaster tool help page

Hidden markup Make sure that your rel="author" link is not invisible to humans using techniques like display:none or CSS. Broadly speaking, Google won’t display any information that cannot be viewed by humans.

As if there is a way for a human to see the relationship info without viewing the source HTML. It is as if google needs more incoming links into the g+ profile pages to promote them in search results….

But even google understands how stupid this rule can be in practice and allows authorship info to be specified in link tags in the header. (which is actually exactly one of the options the HTML5 spec specifically specifies)
