Micro-blogging site Twitter said it is testing a new way to display tweets that link out to e-commerce product pages. With a new Twitter card format, the company is experimenting with tweets that include a big "Shop" button and integrate product details directly into the tweet itself, including the product name, shop name and product pricing, TechCrunch reported last week.

This format could potentially come into play as part of Twitter's larger push to become a creator platform, with its recently announced plans for a "Super Follow" subscription.
