Search Engine Land has dubbed this experimental platform as Business Cards. Google first introduced it as means to share real time Presidential Candidate views on issues in a carousel of cards that could include pictures, text and video. At introduction, only presidential candidates and related organizations were approved for their use.
Since that time, search engine results have been found for a few companies using the carousel of posts technique. Note the arrow which allows you to shift through the posts.
In This Post at Google (https://www.google.com/posts/) , the platform is described and there is the suggestion that you may be able to sign up for it, but for now it is invite only.
Front Man Marketing will continue to watch and let you know if and when you can participate. Give us a call or see our Contact Us page.
