Twitter Inc said on Tuesday it is going to start testing ads on its Fleets, which is its new feature, since it works to give advertisers more options.

Social Media has previously stated that it has set an objective to double its annual revenues by 2023, in part through the sale of ads on more parts of its site and the mobile app.

The company said that fleet ads will be the first on Twitter to appear on phones with full screen. Advertisers often like full-screen ads because they attract the attention of the user.

The new offering is part of Twitter’s aim to catch up to larger social media platforms like Facebook Inc and Snap Inc, which have long offered a “Stories” posts feature that disappears after 24 hours and is monetized with ads.

Brands that create Fleet ads can also use a feature that would direct a user to the company’s website or other web destination if they swipe up on the ad.
