Image Formats, Performance and Cognitive Load

Images are a crucial component for successful conversions: they evoke emotions, build trust and prompt action. They also form 2/3rds of our website’s weight & have a high correlation to page load time, Speed Index and Time To First Meaningful Interaction. That’s why at trivago, we’re working towards highly optimized and well-targeted visuals. In this talk, you’ll learn how we optimize and deliver images for maximum effectiveness and which important lessons we learned along the way.
