"Starting today, advertisers can now use the power of video to promote their mobile apps on Twitter," said Ivan Santana, product manager at Twitter.

According to the San Francisco-headquartered company, the Video App Card shows people a preview of the app, resulting in a more educated and more qualified user joining as a subscriber.

"In beta, we saw that this highly engaging format helped some advertisers nearly triple their conversion rate from app click to install," Santana said.

"The new feature auto-plays in timelines, giving the app maker an opportunity to engage their audience with attention-grabbing content at all points throughout their day," he added.

The company is offering its entire suite of targeting tools, including interest, keyword, device, location, and tailored audiences to ensure that the app maker reaches people most likely to be interested in their app, at just the right time.

According to Twitter's research, nearly 82 percent of users watch videos on Twitter, and 90 percent of video views are on mobile devices.
