The website design should always run on all platforms. If the customer has a cell phone or a tablet or desktop through your website, then the total web experience will be the same. It is more likely that the visitor will be on the website for a long time.
If visitors are not able to find what you want on your website, they find a key to converting online shoppers who are looking for products and services on the Internet, where the company is more likely to buy a mobile. There is a well designed and fully functional website on both device and desktop computer.
