Just a quick blog to show how easy it is to associate content with your google + profile and get your mugshot to appear next to the content in the search engine listings.
1) Using WordPress, set up author account and associate with email linked to the domain that the content is to be written on. E.g. For this site I will be using Nick@joelson.co.uk
2) Make sure that each article or post you publish on that domain has a clear byline identifying you as the author (for example, “By Nick Joelson” or “Author: Nick Joelson”)
3) Visit the Authorship page and submit your email address to Google. No matter how many articles or posts you publish on this domain, you only need to do this process once. Your email will appear in the Contributor to section of your Google+ profile. If you want to keep your email private, change the visibility of your link.
4) To see what author data Google can extract from your page, use the rich snippets testing tool.
Not sure how it takes but I just set this up so will update when ready.
