How to add or edit a Twitter Creator Username on any page or blog post
Assigning a Twitter Creator to content, whether it is a page or blog post, is important to help Twitter relate that content to a specific user when it is shared via Twitter.
For instance, if you run an editorial website with multiple content creators and you would like to relate certain content to them, well then you can do so by following this guide.
Your Twitter Creator Username should not be confused with the Twitter Site Username.
The Twitter Site Username is for your website owner or business name, e.g. uSkinned.
The Twitter Creator Username is defined on a page by page (or post by post) basis and should only relate to the content of that page.
Login to the CMS.
In the tree menu, go to any page or blog post.
Go to the SEO & Share tab.
Locate the label 'Twitter Creator Username'.
Enter the username of the person who has created this content. For example, uSkinned.
Save and publish the page or blog post.
The content on this page or blog post will now be directly linked with the user you enter in Step 5 whenever it is shared via Twitter.
