Landing page optimization is about getting your landing page optimized or well-constructed for the visitors to stay long and read out your campaign details before clicking the CTA or call-to-action button.  A landing page must be well-constructed in the sense that it should have all the necessary parts like a capture form, a CTA button, words that explain your product or service in short, one or two testimonials about your product or service, a video (if necessary) and a few graphics that supplement your business.
