Twitter will start showing businesses selling products at the top of their profile page, the social networking company said Wednesday, as it seeks to capture a share of the lucrative online shopping world.

The San Francisco-based company is following in the footsteps of big competitor Facebook , which last year launched a “shop” feature to allow consumers to buy products directly via Facebook and Instagram .

Twitter says it will begin testing the new shopping feature in the United States with "a handful of brands."

Users can scroll through a carousel of products at the top of the brand's profile. The customer can tap on a product, and then pay through the retailer’s website.

This test is a new attempt to offer shopping on Twitter. The company has previously tested the "Buy Now" button and product page in 2015.
