The Google Authorship Tag is a hidden text attribute that can be added to any web page or blog post to indicate who wrote it. When someone clicks on the link, they will be taken to the GoogleAuthors website, where they can learn more about the author and see their other work.
The benefit of using this tag is twofold. Firstly, it helps improve your credibility as an authority in your field by showing that you are well-respected by Google. Secondly, including this tag could help boost traffic from search engines, as people who click on links may look for insight into the author's background or expertise.
