Social Media should have impacted on how you interact with your customers by now, not least if you are purely an online business. There is still a disconnect though between business’ Social Media efforts and their website.
Social network website design though is the inevitable next development for any true social business. Social media can fill in the gaps between what a bricks and mortar store or office offers and what can be offered online: and with a true social business take things even further. Even if you have a bricks and mortar premises for your business when people come to your website they should be able to communicate and interact with you as well as if they had visited your store. Many businesses of course direct people from their sites to external Social Media sites to interact but with social network website design you can keep people on your site and ensure that the way they can communicate and interact suits the offering you want to deliver.
