Using Twitter cards in social media marketing

Twitter Cards enable publishers to attach media experiences to tweets — beyond the 140-character limit.
They add a few lines of HTML metadata to blog posts and other thought leadership content that enable brands to stand out from the pack in Twitter feeds that are full of text. They can help you drive website traffic, introduce new products and services, share rich content such as videos, and improve engagement. Bypassing the character limit also helps increase conversion rates.
Tweets with images and other media attract:
• 89 percent more “favorites”
• 18 percent more clicks
• 150 percent more re-tweets
