For an example, let's search "baseball bats" and see if an ad effectively demonstrates what a customer will find on the landing page.
Ad
Landing Page (click to view)
Looking at the ad, we see some keywords that we expect to find in the webpage. These include: "free shipping," "free returns," "24/7 customer service." Now notice the first thing a customer will see at the top of the page is that there is free shipping everyday. For many customers, free shipping is going to catch their attention and give them a good reason to do business with this company. In to top right, there is a link for returns for customers that already bought a product but need to send it back. Customer service is a big deal for many consumers, and in several areas on the landing page, there are different ways for which a customer can contact the company with any questions or issues. On many websites, a customer may have to go through several pages to find this information. For them to have all of this on their landing page makes them seem like a company someone would want to do business with.
