A before-and-after slider is a highly persuasive way to sell CGI creation because it turns your work into instant proof of transformation, not just a nice-looking image. By letting prospects drag between the existing space and the CGI vision, they can see the value you add in a split second, which builds trust and removes doubt about “what they’ll actually get.” This simple interaction keeps them engaged on the page for longer and makes your CGI far more memorable, helping move them from interest to enquiry much faster.
