It used to be standard practice to create a designated landing page that would “squeeze” people into a sale because it focuses on one product, there’s no menu, no distractions, no alternate buttons, etc. This is not recommended because on average people view 2.8 pages before converting. So, this means a new visitor who lands on the website’s product page, might also view other products or view the homepage or the contact us page before going back to their original landing page to purchase/convert.
