Twitter Fleets – the newbie in the world of Twitter marketing has taken a step ahead.

“Fleet ads are full-screen billboards for advertisers,” Twitter senior product manager Justin Hoang and global product marketing manager Austin Evers wrote in a post announcing the ads. It’s partnering with a “handful” of advertisers in what it calls an “experiment,” making the Fleet ads visible to a limited group of US users on iOS and Android.

The ads support images and video in 9:16, and videos can be up to 30 seconds long. Brands can choose to add a “swipe up” call-to-action and will be able to access standard Twitter ad metrics, including impressions, profile visits, clicks, website visits, and other information.

What are Twitter Fleets?

Fleets are Twitter posts that are temporary. After 24 hours, your Fleet is gone forever. Fleets are only post-able and visible on Twitter mobile apps. This is something similar to Instagram stories.

Today, people use Twitter Fleets to point to other tweets they’ve posted, or to share personal updates, photos and commentary. However, unlike Stories on other platforms, like Snapchat or Instagram, Fleets still offer a fairly bare-bones experience in terms of creator tools. You can change the background color, and add stickers and text, but that’s about it.

Twitter Fleet ads will launch today in the U.S. across both iOS and Android.
