“Plus Ones” are similar in function to a Like in Facebook or LinkedIn. Using +1 is a great way to indicate “I like this” or “I agree” on a post or comment without leaving a comment. +1’ing can occur on a post, a share, or a comment, as well as photos or videos.
Google+ has also given the ability to +1 an external website site by adding a bit of code to the website or blog. These +1s have the added benefit, if configured correctly, to quickly boost your search rankings in Google Search. Be sure to contact your website developer to have them implement the +1 button on your site. (Details on how to implement that are out of the scope of this book.)
