The purpose of the Twitter Card

Twitter Cards make content more attractive because it automatically illustrates your web links that you share. Each card has a built-in content assignment, which displays the appropriate Twitter accounts for the content specified by you. Users will be able to track and view the profiles of assigned accounts directly from the card. This makes it easier for the user to read by automatically illustrating shared web links without inputting a number of characters on the tweet. A tweet with metadata increases visibility and therefore virality among followers.

Combine Open Graph data with Twitter Cards

Twitter card tags are similar to Open Graph tags and are based on the same conventions as the Open Graph protocol.

When we use the Open Graph protocol to describe data on a page, we have the possibility of easily generating a Twitter card without duplicating the tags and the data.

When the Twitter card processor looks for tags on a page, it checks and secures the Twitter-specific property first, and if missing, reverts to the Open Graph supported property. Allowing it to be set on the page independently and lessen the amount of duplicate markup needed to describe content and experience.

To remember: in the code you must complete the words "twitter: card, twitter: site, and twitter: creator" with your information for perfect optimization.
