CRO: Landing Page Optimization Techniques

Have you had any experience of clicking an ad on a search results page that took you to the website, and you decided to come off it to look for another option for reasons unknown? I have experienced this many times without giving myself the time to analyze, when I could actually benefit from the site/page. As a marketer or a business owner, this is why you need to understand how neuroscience affects decision making and focus on creating the best landing page experience that would give the human brain a great experience in the conversion funnel.
