Nowadays content copying or duplicacy has become a very big issue that has effected many websites rank. However there is no need to worry about it and google has kept in mind these kind of issues. Google authorship is the example of this. Google has been taking steps to control the duplicacy issues. You need to activate google authorship so that google will know that you are a legitimate user for your blog posts or articles. In future if anybody copy your content to use in their website, Google will know it very quickly. As far as my knowledge concerned google will give you extra credit by showing your profile picture in the search results along with your blog posts or articles. In this way when people search for a keyword related to your content or post then your content or post will show up in the search results along with your profile pictures and your authentic name. I was searching for Google authorship on Google I found a blog very informative and want to share all of you.
