Comedian Jerry Seinfeld's new web series, "Comedians in Cars Getting Coffee," premieres July 19. What is noteworthy already is how the show has been marketed via online videos.

As ReelSEO noted, what sticks out about the video ads is that they both provide just enough to intrigue viewers without spelling out what exactly the show will be all about.

The first 58-second video ad, released July 9, simply showed Seinfeld and a few other comedians riding in classic cars. The second promo, a two-minute video released July 12, showed short clips of Seinfeld conversing with a variety of other famous comedians. The longer promo video had more than 235,000 views on YouTube after six days.

The key to the success of this video ad campaign, according to ReelSEO, was it relied on intrigue that built with each new video, as opposed to just relying on the celebrity names attached.

"But what I like about this series is just the way they're teasing it," ReelSEO writer Chris Atkinson said. "They're not giving away everything and they know exactly what to show in order to get you interested."
