Conversion Optimization is the process of improving a website or landing page to increase the percentage of visitors who take a desired action, such as making a purchase or signing up for a newsletter. This involves analyzing user behavior, identifying barriers to conversion, and implementing changes to enhance the user experience. Techniques for Conversion Optimization include A/B testing, where different versions of a page are compared to see which performs better, and optimizing call-to-action buttons to make them more appealing. The goal is to create a seamless experience that encourages users to engage and convert effectively.
