The CTA
The CTA is an interactive Video Format in the Goldbach Video Network, where your spot is combined with a clear, prominent call-to-action. A clearly visible button appears during or after the video. This button directs users directly to your landing page, a form, or your shop. The Format is ideal for all campaigns in which concrete actions should result from attention.
