WordPress plugin for the new Google original source meta tag
Publishers can now use metatag to help Google determine which URL(s) should be considered the original version of an article: « Original-source » meta tag. (see Google News help for publishers)
This plugin will add a meta box to your « add new » post and page to add up to 5 Original sources URLs.

By adding URLs, the plugin will automatically add « original source » metag tag to your posts and pages header.

If you publish an article that consists entirely of original reporting, do nothing and just let the plugin add your URL (permalink) as the original-source.

Just works like a charm, thanks.
Merci, c’est exactement ce qu’il me fallait pour tester. Si j’ai compris cela ajoute la balise uniquement aux articles et aux pages, pas aux catégories et aux tags
Exact Marc, parce que les tags et catégories ne contiennent pas généralement de contenu unique, mais les articles et pages si
Absolutely perfect – thanks
Is there such a module for Drupal Sites?
Armen our team is developping WP plugins only. For Drupal the easiest way to add metatags is probably to automatically search your post content for outbounds links with something like that in a php function:
and add them to the header by a function call.
Thanks for a great plugin!
An option to include the source at the bottom of the post as a link a’la engadget.com would be excellent
