The landing pages will be more effective on customers and also will jam more traffic into your product. In normal websites, the customer gets to divert by other information and much more. Whereas, for landing websites, their focus will be just on one product and its description.
You will give your customer a single call to action. Thus, you can control the steps of the person who has already come down on your page. There your customers will not get a wide range of options for them to click. The chance of navigation will be within the limit for customers, which will help to allure them.
