Standout tag

Google introduced a new content tag called "standout":-
Google said If we put the tag in the HTML header of one of our articles, Google News may show the article with a ‘Featured’ label on the Google News homepage and News Search results.

The syntax for this new tag is as:
<link rel="standout"href="http://www.example.com/scoop_article_100.html"/>

We can use the tag to point to own content or to point to others with standout stories.

Because the Standout tag put in the HTML header of articles, so readers can see.it will only be seen by automated systems like Google News.
This tags work best when news publishers recognize not just their own quality content, but also the original journalistic contributions of others when your stories draw from the standout efforts of other publications.Standout tags are just one of the signal among the many signals that algorithmically determine prominence on Google News.

Google will ignore tags when used more than 7 times in one week to promote internal content. There is no limit on using the tag to promote the work of another publication.
