Stories make full use of the mobile screen, offering advertisers a beautiful, distraction-less canvas.
Stories expands to full-screen when the user interacts with the start banner/video in the feed. Choose between a click-to-play or swipe symbol to expand to Stories.
Photo and Video Stories are displayed in a timeline, 5-6 seconds is recommended per Story but is optional, and the user can tap to see the next one, tap back or pause the story – just place the finger anywhere on the screen.
The user swipes up to visit the landing page and you can add optional CTA-text to your Stories in our AdBuilder, making them more actionable, and drive Traffic, Conversions, Lead generation, or App-installs.
This format is easy to create in our AdBuilder by uploading videos and images and you can use our Color Picker for your CTA-text and swipe-up-symbol. You can also ask us to do it for you.
