Which ad format is known for sliding content to the left upon user interaction?

The slider ad format is specifically designed to allow content to move horizontally, typically sliding to the left upon user interaction. This format encourages engagement as users often can interact with the ad by swiping or clicking, prompting the content to shift. Slider ads are effective because they can showcase multiple pieces of content in a single ad unit, providing a dynamic visual experience that captures the user's attention.

In contrast, banner ads are static or can have limited animations but do not inherently involve sliding mechanics. Interstitial ads cover the entire screen and usually appear during transitions between content rather than utilizing sliding motion. Text ads are primarily composed of written content without any dynamic elements or sliding features. Thus, slider ads distinctly stand out due to their interactive and engaging content presentation, making them optimal for creating interest and user interaction.
