I have a question regarding the implementation of Google Authorship, especially when having multi-author blogs in mind in the future (currently: single author). The Yoast WordPress SEO plugin represents the 2-link method, using the new <link rel="author" google+ url> meta tag on each post and page. This means masses of links to G+ from all these content pages/posts.
In contrast, the 3-link method links every content page/post via the tag rel="author" with its respective author page on the same domain (all internal linking), and there is a single rel="me" link that creates the connection to the respective author's G+ profile, for all pages and posts!
Q: Is there any SEO downside to using the 2-link method in terms of the number of outlinks it creates?
Q: Is it even possible to create this 3-link method using the Yoast WordPress SEO plugin? If not, how could this be achieved (rel="author" links
Q: Not directly related to this plugin, but to do with the implementation of Google authorship (which is part of the plugin). How can I customize the author bio page in WP?
