Your website is where the magic happens. This is the place where your audience needs to convert. Whether it is encouraging prospective buyers to sign up for your newsletter or fill out a form for a demo, the key is to optimize your website for converting browsers into actual leads.  Pay attention to forms, Calls-to-Action (CTA), layout, design, and content.
If links and looks are set, begin interacting with the page. Abandon it, adjust the window size, convert. Are error messages appearing when they’re supposed to (if, for example, you don’t input all the form’s required info)? Is your CTA button working? If you abandon the page, are you retargeted with ads? When you resize the window, does your landing page respond accordingly?
