Twitter Cards are very nice looking representation of your website posts and pages that can enhance user experience when they see posts from your website on Twitter. Twitter Cards can be displayed inside the timeline, or when you open a tweet. With GD SEO Toolbox Pro you can easily configure how the Twitter Cards will look, and to control content displayed on the card for each page of your website.
You can select between two types of Twitter Cards (one with the large image, as on the image on the right), and you can add your Twitter username to connect your posts to your Twitter account.
Since every card needs to have a title, description, and image, it is important to provide fallback data for the plugin to use in the case where there is no sufficient data available.
