If one of your posts has been created by one more author, how can you give them credit for a single post? WordPress allows its user to give credit to a single user for a post. It means by default, posts are assigned to a single author.
But you can give credits to multiple authors for a single post. Just you have to install and activate the Co-Authors Plus plugin.
just go to the customize option of the respective post where you want to credit multiple authors. You will see there has a ‘Authors’ box just underneath the post editor.
Then you can add desired author name into the box.
This is how you can give credit to multiple authors for a single post.
