Also, PCI (Payment Card Industry) is a crucial element in your site that will enable your customers to use credit and debit cards. You can also have SSL (Secure Socket Layers) certification to assure your customers that their data are safe. By doing this, you can easily convert the visitors to potential buyers.
Security will eliminate warning from browses
Google cannot keep those insecure sites. If your e-commerce website is not secure, Google will keep on sending warning for you to secure your site. If you fail to integrate your site with security features, your site will become inactive. With this, you can get losses. The effort you had to invest your business can go to waste which will force you to start the business from scratch.
