Social media is here to stay and has become a huge asset for companies to advertise themselves and build a relationship with existing and new customers.

The marketer will then need to create appealing, interesting and catching content that customers will reward with attention and hopefully with feedback. The company will also need to understand the level of the tech-related requirements for the site to work correctly, and how literate the users need to be regarding this. For example, will it use Java or Flash applications? Which screen resolution is optimal for maximum site appearance?
It is also imperative to think of the level of control the customer will have in the site. I believe that most of the time, people sign in on customer service websites, forums and discussion communities to complain about a product, and try to convince others to not acquire it. The marketer must keep an attention to detail in the wording and content in the website, so it brings positive memories from visitors and engages them to make comments about it. My point is: satisfied customers seldom comment on websites or Tweet about it, so encourage them to!
As any good online marketing program, it is imperative to keep the target in quality content instead of quantity of users. People who regularly check and interact with your site is better than having hundreds of followers that never do anything in it.
An arising issue with Social Media is privacy. Generally people would say that companies can access your information if you follow their pages on Facebook. They can, if you don’t take care of the settings. Facebook offers plenty of privacy settings so you can specify who is able to see what in your profile. However, the blasting majority of users only have the default privacy settings. Therefore, a lot of the 500+ million Facebook users are open for marketers to check their profile. Nonetheless, even if people were careless about companies checking up on their profiles, marketers would need a lot of spare time to check them in a one-by-one basis, so I don’t think anybody should take so much concern on this.
Companies from medium to large-size with important marketing efforts also need to maintain a balance between offline and online strategies and take care of both at the same time. The content must be coherent between both worlds. This increases time and efforts, which turn into additional costs.
Finally, firms must understand the increasing power of social media these days. So hop on the train, or be left behind.
