Have you noticed how some Google listings show a wee photo of the author along with a link to their Google Plus profile? This nifty feature is part of Google Authorship which is a way of associating your name and Google Plus profile with content you create around the web. Because results that have authorship stand out much more, you’ll see better click throughs to your content. It’s pretty easy to set up if you follow Yoast’s guide. This is the perfect reason to stop avoiding setting up your Google Plus profile !
